Auditory feedback perturbation studies have indicated a link between feedback and feedforward mechanisms in speech production when participants compensate for applied shifts. In spectral perturbation studies, speakers with a higher perceptual auditory acuity typically compensate more than individuals with lower acuity. However, the reaction to feedback perturbation is unlikely to be merely a matter of perceptual acuity but also affected by the prediction and production of precise motor action. This interplay between prediction, perception, and motor execution seems to be crucial (...) for the timing of speech and non-speech motor actions. In this study, to examine the relationship between the responses to temporally perturbed auditory feedback and rhythmic abilities, we tested 45 adult speakers on the one hand with a temporal auditory feedback perturbation paradigm, and on the other hand with rhythm perception and production tasks. The perturbation tasks temporally stretched and compressed segments (onset + vowel or vowel + coda) in fluent speech in real-time. This technique sheds light on the temporal representation and the production flexibility of timing mechanisms in fluent speech with respect to the structure of the syllable. The perception tasks contained staircase paradigms capturing duration discrimination abilities and beat-alignment judgments. The rhythm production tasks consisted of finger tapping tasks taken from the BAASTA tapping battery and additional speech tapping tasks. We found that both auditory acuity and motor stability in finger tapping affected responses to temporal auditory feedback perturbation. In general, speakers with higher auditory acuity and higher motor variability compensated more. However, we observed a different weighting of auditory acuity and motor stability dependent on the prosodic structure of the perturbed sequence and the nature of the response as purely online or adaptive. These findings shed light on the interplay of phonological structure with feedback and feedforward integration for timing mechanisms in speech. (shrink)

In the 1970s and 1980s, a multitude of cognitive rehabilitation programs proliferated to facilitate recovery after brain injury. However only a few programs provided a framework for ameliorating disturbances in the cognitive, psychological, and interpersonal spheres of the brain-injured patient. Greatly influenced by Leonard Diller and Yehuda Ben-Yishay’s ideas and methods, George P. Prigatano began, in early 1980, a holistic neuropsychological rehabilitation program at the Presbyterian Hospital in Oklahoma City (Oklahoma). The objective of this paper is to summarize the contributions (...) of George P. Prigatano to neuropsychological rehabilitation and clinical neuropsychology during his 50th year of practice. The main body of the paper is structured in three sections. The first section briefly explains the history of neuropsychological rehabilitation in the twentieth century and the emergence of holistic neuropsychological rehabilitation programs in the 1970s. The second section describes the contributions of George P. Prigatano to neuropsychological rehabilitation and clinical neuropsychology (written by AGM). In the third section, the second author (GPP) prepared an autobiographical statement, which attempts to summarize some of the personal and professional experiences which influenced his work. George P. Prigatano’s contributions to neuropsychological rehabilitation and clinical neuropsychology are essential to understanding the therapeutic approaches currently used in the treatment of brain-injured patients.

Objective: Basic temporal dysfunctions have been described in patients with schizophrenia, which may impact their ability to connect and synchronize with the outer world. The present study was conducted with the aim to distinguish between interval timing and synchronization difficulties and more generally the spatial-temporal organization disturbances for voluntary actions. A new sensorimotor synchronization task was developed to test these abilities. Method: Twenty-four chronic schizophrenia patients matched with 27 controls performed a spatial-tapping task in which finger taps (...) were to be produced in synchrony with a regular metronome to six visual targets presented around a virtual circle on a tactile screen. Isochronous (time intervals of 500 ms) and non-isochronous auditory sequences (alternated time intervals of 300/600 ms) were presented. The capacity to produce time intervals accurately versus the ability to synchronize own actions (tap) with external events (tone) were measured. Results: Patients with schizophrenia were able to produce the tapping patterns of both isochronous and non-isochronous auditory sequences as accurately as controls producing inter-response intervals close to the expected interval of 500 and 900 ms, respectively. However, the synchronization performances revealed significantly more positive asynchrony means (but similar variances) in the patient group than in the control group for both types of auditory sequences. Conclusion: The patterns of results suggest that patients with schizophrenia are able to perceive and produce both simple and complex sequences of time intervals but are impaired in the ability to synchronize their actions with external events. These findings suggest a specific deficit in predictive timing, which may be at the core of early symptoms previously described in schizophrenia. (shrink)

PurposeChildhood onset speech fluency disorder is possibly related to dopaminergic dysfunction. Mesencephalic hyperechogenicity detected by transcranial ultrasound might be seen as an indirect marker of dopaminergic dysfunction. We here determined whether adults who stutter since childhood show ME.MethodsWe performed TCS in ten AWS and ten matched adults who never stuttered. We also assessed motor performance in finger tapping and in the 25 Foot Walking test.ResultsCompared to controls, AWS showed enlarged ME on either side. Finger tapping (...) was slower in AWS. Walking cadence, i.e., the ratio of number of steps by time, tended to be higher in AWS than in control participants.DiscussionThe results demonstrate a motor deficit in AWS linked to dopaminergic dysfunction and extending beyond speech. Since iron deposits evolve in childhood and shrink thereafter, ME might serve as an easily quantifiable biomarker helping to predict the risk of persistency in children who stutter. (shrink)

The phenomenon of experienced agency is related to perceptual‐motor coordination, and Solfo and van Leeuwen discuss two ways that context can change this relationship. One is that agency is experienced only in contexts where environmentally‐coupled actions are stitched together over time to form long‐range correlations. The other is that the locus of agency depends on the temporal relationship between actions and events in the environment.

Sense of agency can be defined as the self-awareness of bodily movement, whereas extended agency as the self-awareness of affecting, through movement, events concomitant with movement. As a distinctive manifestation of agency, we review Spizzo's effect. This effect arises when agents coordinate their rhythmic movements with visual pulses. Once coordination is established, agents feel controlling the onset or the offset of the pulses through their movements. Spizzo's effect, therefore, constitutes a manifest case of extended agency, in which agents are aware (...) of controlling, through movement, the pulses temporally concomitant with movement. We propose that sense of agency requires continuity of kinesthesia, which in turn requires the continuity of selfhood. The continuity of kinesthesia is necessarily deduced from the consistent kinematics observed in movements, whereas the continuity of selfhood may stem from the patterns of rhythmic coordination that humans encounter ever since intrauterine life. The primacy of these patterns in adults is in accordance with phenomena such as Spizzo's effect, which require coordination to be induced. We, therefore, propose coordination as the fundamental interaction from which selfhood, kinesthesia, and agency arise. (shrink)

Human beings adapt the spontaneous pace of their actions to interact with the environment. Yet, the nature of the mechanism enabling such adaptive behavior remains poorly understood. The aim of the present contribution was to examine the role of attention in motor timing using time series analysis, and a dual task paradigm. In a series of two studies, a finger-tapping task was used in sensorimotor synchronization with various tempi and motor complexity. Time series analyzes indicated that two different (...) timing strategies were used depending on the speed constraints. At slow tempi, tapping sequences were characterized by strong negative autocorrelations, suggesting the implication of cognitive predictive timing. When moving at fast and close-to-spontaneous tempi, tapping sequences were characterized by less negative autocorrelations, suggesting that timing properties emerged from body movement dynamics. The analysis of the dual-task reaction times confirmed that both the temporal and spatial constraints impacted the attentional resources allocated to the finger-tapping tasks. Overall, our work suggests that moving fast and slow involve distinct timing strategies that are characterized by contrasting attentional demands. (shrink)

Background: Recently, attention has grown toward cerebellar neuromodulation in motor learning using transcranial direct current stimulation. An important point of discussion regarding this modulation is the optimal timing of tDCS, as this parameter could significantly influence the outcome. Hence, this study aimed to investigate the effects of the timing of cerebellar anodal tDCS on motor learning using a sequential finger-tapping task.Methods: One hundred and twenty two healthy young, right-handed subjects were randomized into four groups. They performed 2 days (...) of FTT with their non-dominant hand on a custom keyboard. The task consisted of 40 s of typing followed by 20 s rest. Each participant received ca-tDCS at the appropriate timing and performed 20 trials on the first day. On the following day, only 10 trials of FTT were performed without tDCS. Motor skill performance and retention were assessed.Results: All participants showed a time-dependent increase in learning. Motor performance was not different between groups at the end of T1. ca-tDCS did not facilitate the retention of the motor skill in the FTT at T2. Thus, our findings indicate an absence of the effect of ca-tDCS on motor performance or retention of the FTT independently from the timing of stimulation.Conclusion: The present results suggest that the outcome of ca-tDCS is highly dependent on the task and stimulation parameters. Future studies need to establish a clear basis for the successful and reproducible clinical application of ca-tDCS. (shrink)

Language experience shapes the gradual maturation of speech production in both native and second languages. Structural aspects like the connectedness of spontaneous narratives reveal this maturation progress in L1 acquisition and, as it does not rely on semantics, it could also reveal structural pattern changes during L2 acquisition. The current study tested whether L2 lexical retrieval associated with vocabulary knowledge could impact the global connectedness of narratives during the initial stages of L2 acquisition. Specifically, the study evaluated the relationship between (...) graph structure and L2 learners’ oral production in the L2 and L1. Seventy-nine college-aged students who were native speakers of English and had received classroom instruction in either L2-Spanish or L2-Chinese participated in this study. Three tasks were used: semantic fluency, phonemic fluency and picture description. Measures were operationalized as the number of words per minute in the case of the semantic and phonemic fluency tasks. Graph analysis was carried out for the picture description task using the computational tool SpeechGraphs to calculate connectedness. Results revealed significant positive correlations between connectedness in the picture description task and measures of speech production in the phonemic and semantic fluency tasks. These correlations were only significant for the participants’ L2- Spanish and Chinese. Results indicate that producing low connectedness narratives in L2 may be a marker of the initial stages of L2 oral development. These findings are consistent with the pattern reported in the early stages of L1 literacy. Future studies should further explore the interactions between graph structure and second language production proficiency, including more advanced stages of L2 learning and considering the role of cognitive abilities in this process.

Motor skills of professional musicians can be regarded as a model to investigate human skill acquisition after prolonged practice. Although rhythmic tapping skills of musicians such as drummers and pianists were investigated previously, the tapping performance of hand percussionists is still largely unknown. In this study, we investigated the tapping performance of professional and amateur darbuka players. Three tapping tasks were performed: single-, double-, and triple-finger tapping tasks. The participants were asked to tap as (...) fast as possible for 12 s in the single-finger tapping task while they tapped as fast and alternate/even as possible in the double- and triple-finger tapping tasks. The tapping speed and variability of inter-tap interval and tapping amplitude were assessed for each task. In the single-finger and triple-finger tapping tasks, there was no significant difference in the tapping speed between the professional and amateur darbuka players. In the double-finger tapping task, the tapping speed was significantly faster in the professional players than the amateur players. Interestingly, the professional players showed faster tapping speed in both familiar and unfamiliar patterns of finger coordination. The tapping speed of the double-finger tapping task was significantly correlated with the duration and the age of commencement of darbuka training. The professional players also showed less variability of ITI and tapping amplitude compared to the amateur players. These results suggest that prolonged practice of the hand percussion increases the performance stability and coordination speed of both familiar and unfamiliar patterns. (shrink)

Öz: Bu makale Neolitik döneme ait ve Anadolu’da inşa edilen ilk tapınak olma özelliğine sahip Göbeklitepe’yi ele almaktadır. Arkeologlara göre burası insanlığın en eski tapınaklarından biridir. Göbeklitepe, yerleşik hayattan ve tarımsal üretimden yoksun olan avcı-toplayıcı toplulukların dinsel inanışları hakkında çok önemli bilgiler sunar. Bu tapınak, arkaik insanların dinden ve inançtan yoksun ilkel bir hayat sürmediklerini, aksine bir inanca sahip olduklarını, inançlarını yaşamak için tapınak inşa ettiklerini ve zengin bir dinî sembol kullandıklarını göstermektedir. Göbeklitepe, insanların yerleşik hayata geçip kendisi için konut (...) yapmadan, hayvanları evcilleştirmeden ve tarımsal üretime başlamadan önce dinî ihtiyaçlarını karşılamak için tapınak yaptığının bir göstergesidir. Özet: Bu makale Neolitik döneme ait ve Anadolu’da inşa edilen ilk tapınak olma özelliğine sahip Göbeklitepe’yi ele almaktadır. Şanlıurfa yakınlarında 1995 yılında başlatılan arkeolojik kazılar, insanlık tarihine bakış açımızı değiştirmiş ve geçmiş hakkında sahip olduğumuz bilgilerin doğruluğunu test etme imkânı sunmuştur. Göbeklitepe, arkaik insanın inanç ve düşünce dünyası hakkındaki bilgilerimizin gerçeği yansıtmadığını göstermiştir. Yaşamını avcı-toplayıcı olarak sağlamaya çalışan, din ve soyut düşünceden yoksun olduğu düşünülen, çanak-çömlek yapmasını bile bilmeyen, tarımı ve yerleşik hayatı keşfetmemiş insanların yoğun ve zengin bir sembolik anlatıma sahip tapınaklar yapması, bilim adamlarını derinden etkilemiştir. Toplamda 20 adet olan ve çapı 10 -30 metre arasında değişen dairesel yapılardan oluşan Göbeklitepe tapınaklarının en ilgi çekici unsuru, T biçiminde olan ve üzerinde soyut sembol ve hayvan kabartmalarını bulunduran dikili taşlardır. Dairesel yapının merkezinde iki adet ve çevresinde 10 ile 12 adet arasında T biçiminde yaklaşık 200 tane dikili taş bulunmaktadır. Bu T biçimindeki dikili taşlar üzerinde kapsamlı bir inceleme yapıldığında ve kadim Anadolu ve Mezopotamya uygarlıklarının dinsel inanışları ve tapınak kültü göz önünde bulundurulduğunda, bu dikili taşların tanrıları sembolize ettiği anlaşılmaktadır. Göbeklitepe, çocukları veya daha küçük dereceli tanrılar tarafından çevrelenen ve bu tanrıların oluşturduğu çemberin merkezinde yer alan tanrı ve tanrıça çiftinin oluşturduğu tanrılar panteonunun kutsal alanıdır. Göbeklitepe bir tapınak olmanın ötesinde karanlıkta kalmış bir inanç sisteminin en önemli temsilcisi olarak karşımızda durmaktadır. Yazılı kaynakların bulunmadığı ve sınırlı arkeolojik verilerin elde edilebildiği Neolitik Dönemin erken evresine ait olan Göbeklitepe, bu dönemde yaşamış arkaik insanın inanç ve düşünce dünyasını bize göstermektedir. Bu megalitik yapının yapısal ve biçimsel özellikleri, arkaik insanın sanıldığı gibi ilkel olmadığını kanıtlamaktadır. Göbeklitepe, dinin doğuşu ve gelişimi konusunda çok önemli bilgiler sunmaktadır. Özellikle evrimci ve pozitivist bakış açılarıyla oluşturulmuş ve dinin büyü, ruh, korku, atalara tapma gibi basit ve asılsız yapılardan doğup zamanla karmaşık ve kurumsal inançlar biçimine dönüştüğünü öne süren teorilerin gerçeği yansıtmadığını göstermiştir. Araştırmacılar, avcı-toplayıcı toplulukların yerleşik hayata ve tarımsal üretime geçtikten sonra toplumsal yaşamla birlikte bazı sorunlarla karşılaştıklarını ve bu sorunlara çözüm arayışının dinlerin doğuşunu hazırladığını düşünüyorlardı. Diğer bir ifade ile kurumsal dinler, karmaşık toplumsal yaşamın bir ürünü ve sonucu olarak görülüyordu. Fakat Göbeklitepe dinsel inanışların düşünülenden çok daha eski dönemlerde, kurumsal olarak ve basit olmayan formlarda bulunduğunu göstermiştir. Göbeklitepe’nin, bilinen en eski ve ilk tapınak yapısı olduğu iddia edilmektedir. Kendisinden önce bilinen antik tapınaklardan en az 5000 yıl eski olan bu megalitik yapı, uygarlığın gelişiminde dinsel inanışların ne kadar etkili ve önemli olduğunu açık bir şekilde göstermektedir. Uzun yıllar kazı başkanlığını yapmış olan arkeolog Klaus Schmidt, Göbeklitepe’nin ortaya çıkmasıyla birlikte “.. önce tapınak kuruldu sonra şehir. ” sözleriyle, insanoğlunun genlerinde bulunan inanma ihtiyacının ne kadar öncelikli olduğunu ifade etmiştir. Göbeklitepe insanoğlunun konut, tarım ve çanak çömlek gibi temel ihtiyaçlardan önce görkemli ve karmaşık tapınaklar yaptığını ve bunun arkaik insan topluluklarının güçlü inanç duygusundan kaynaklandığını göstermiştir. İnsanın genlerinde bulunan inanma ihtiyacı insana her şeyden önce tapınak yapmayı ilham etmiştir. Göbeklitepe ile temsil edilen inanç sistemi ve düşünce dünyasının ne kadar zengin ve etkili olduğunu, aynı bölgede en az 5000 yıl sonra ortaya çıkan Anadolu ve Mezopotamya uygarlıkları üzerindeki etkisinden anlayabiliriz. Bu uygarlıkların tapınak yapıları ve dinsel inanışları, bu megalitik yapı ile dikkate değer bir biçimde uyuşmaktadır. Bu uygarlıkların karanlıkta kalmış yönlerini ortaya çıkarmada, Göbeklitepe kaçırılmayacak bir fırsat sunmaktadır. Bu megalitik yapı ortaya çıktığında büyük ses getirmiş ve bilim insanlarının ilgisini çekmiştir. Hakkında yazılı ve görsel basında çok sayıda haberin çıktığı bu tapınak kompleksinin, Aden bahçesi, Babil Asma Bahçelerinin kalıntısı, Şaman tapınağı ve uzaylıların merkezi olduğu iddiaları ortaya atılmıştır. Göbeklitepe üzerinde yapılan arkeolojik kazıların ilerlemesi ve onun hakkında daha fazla bilgiye ulaşılması, onun bir ritüel merkezi olarak tapınak olduğunu göstermiştir. Göbeklitepe’nin yapısal ve biçimsel özellikleri, bu yapının her şeyden önce bir tapınak olduğunu göstermiştir. Gerek dikili taşlardan oluşan dairesel yapıları ve gerekse yerleşim yerlerinden uzak yüksek bir tepede bulunması bu düşünceyi güçlendirmektedir. Göbeklitepe’yi avcı-toplayıcı toplulukların ibadet ettikleri, tanrılara kurbanlar sundukları, yılın belirli dönemlerinde dinî festival ve şölenler gerçekleştirdikleri, tanrıların yaşadığı kutsal mekânlar olarak gördükleri ve kutsalı tecrübe ettikleri bir tapınak olarak düşünmek daha doğru bir yaklaşımdır. Göbeklitepe’nin, tarih boyunca inanç merkezi olarak kalmış ve peygamberler şehri olarak bilinen Şanlıurfa’da ortaya çıkması ülkemiz için önemli bir ekonomik ve kültürel fırsat oluşturmuştur. Anadolu’nun ne kadar kadim ve zengin bir kültürel dokuya sahip olduğunu kanıtlayan bu megalitik yapı, ortaya çıktığı günden beri birçok yerli ve yabancı araştırmacının akınına uğramıştır. Bilimsel literatürün en eski ve ilk tapınağı olan Göbeklitepe, arkaik insanın günümüz insanına miras olarak bıraktığı ve insanlığın ilk dönem sırlarını taşıyan gizemli bir tapınak kompleksidir.

A recent contribution to the moral decision-making literature argues that individuals' moral behavior is partially shaped by the amount of moral approbation they expect to receive from their moral referent groups (Jones and Ryan, 1997). This paper examines the nature and content of these previously underexamined sources of moral guidance. In an open-ended empirical test of undergraduate business students (n = 369), we found that 1) significant differences exist between individuals' moral referent groups and work-related referent groups, 2) females (...) were more likely than males to include themselves in their moral referent groups, 3) females were more likely than males to be designated as moral referents, and 4) females were more likely to be included in moral referent groups than in work-related referent groups. The paper also includes a general description of the membership of these business subjects' moral referent groups and presents a variety of suggestions for future research. (shrink)

The existence of shoulder abduction (SA) and finger extension (FE) movement capacity shortly after stroke onset is an important prognostic factor, indicating favorable functional outcome for the hemiparetic upper limb. Here we asked whether variation in lesion topography affects these two movements in a similar or a distinct way, and whether lesion impact is similar or distinct for left and right hemisphere damage. SA and FE movements were examined in 77 chronic post-stroke patients using relevant items of the Fugl-Meyer (...) test. Lesion effects were analyzed separately for left and right hemispheric damage (LHD, RHD) patient groups using voxel-based lesion-symptom mapping. In the LHD group, SA and FE were affected only by damage to the cortico-spinal tract in its passage through the corona radiata. In contrast, following RHD, these two movements were affected not only by cortico-spinal tract damage but also by damage to white matter association tracts, the putamen and the insular cortex. In both groups, voxel clusters have been found where damage affected SA and also FE, along with voxels where damage affected only one of the two movements. The capacity to execute SA and FE movements following stroke is affected significantly by damage to shared and distinct voxels in the cortico-spinal tract in LHD patients and by damage to shared and distinct voxels in a larger array of cortical and subcortical regions in RHD patients.

Evidence exists that the UK National Health Service has had, over many years, persistent problems of negative and intimidating behaviour towards staff from other employees. The evidence also suggests the organisational responses to negative behaviour can be inadequate. A conceptual model of organisational dysfunction was proposed to assist in explaining those responses and the overall culture in the NHS. Through research this model has been tested. Based upon the findings, an extended and developed model of organisational dysfunction is presented. A (...) qualitative approach was taken to research the organisational responses to negative behaviour, and the reasons and motivations for those responses. Forty-three interviews and six focus groups were conducted. There seem to be “islands” and “pockets” with a positive culture; however, the generalised evidence suggests the NHS is systemically and institutionally deaf, bullying, defensive and dishonest, exhibiting a resistance to ‘knowing’, denial and “wilful blindness”; a dysfunctional, perverse and troubled organisation. Totalitarian and Kafkaesque characteristics are identified. The NHS could also be described as a coercive bureaucracy and under certain definitions, a corrupt entity. The NHS appears to be an organisation with a heart of darkness; a “self perpetuating dysfunctional system”. There may be widespread “learned helplessness”. It seems to be a “good news factory”, rejecting and hiding any “bad news”; retreating from reality. The NHS appears to have “lost its way” and its focus/purpose as an institution. The dysfunctional organisational behaviours manifest in the NHS need to be addressed urgently as there is a detrimental, sometimes devastating, impact on the wellbeing of both staff and patients. The NHS needs to embrace an identity of being a listening, learning and honest organisation, with a culture of respect. (shrink)

Stuttering is a neurodevelopmental speech disorder characterized by the symptoms of speech repetition, prolongation, and blocking. Stuttering-related dysfluency can be transiently alleviated by providing an external timing signal such as a metronome or the voice of another person. Therefore, the existence of a core motor timing deficit in stuttering has been speculated. If this is the case, then motoric behaviors other than speech should be disrupted in stuttering. This study examined motoric performance on four complex bimanual tasks in 37 adults (...) who stutter and 31 fluent controls. Two tasks utilized bimanual rotation to examine motor dexterity, and two tasks used the bimanual mirror and parallel tapping movements to examine timing control ability. Video-based analyses were conducted to determine performance accuracy and speed. The results showed that individuals who stutter performed worse than fluent speakers on tapping tasks but not on bimanual rotation tasks. These results suggest stuttering is associated with timing control for general motor behavior. (shrink)

The purpose of this randomized controlled study was to investigate the effects of a 12-week coordinative ability training program on adolescents’ cognitive functioning, using evaluation tests of visuospatial perception, attention, and working memory. We randomly assigned 60 public school students (14–15 years) to either an experimental coordinative abilities training (∼40 min twice/week) group (n= 30) or a control group (n= 30) who received general psycho-physical wellness training (∼40 min., twice a week). At baseline and after training we used two standardized (...) motor tests and a single cognitive measure (Corsi’s Block-tapping test) to assess students’ visuospatial perception, attention, and working memory. We found a significant Time x Group interaction for the Throwing and Catching Test and Corsi’s Block-Tapping test, reflecting a meaningful experimental group improvement (p< 0.001), and there were no significant pre-post changes found in the control group. Thus, a 12-week program of coordinative abilities was able to improve not only coordination skills but aspects of cognitive functioning relevant to academic achievement. (shrink)

We offer a new outlook on the vexed question of the reference of natural-kind terms. Since Kripke and Putnam, there is a widespread assumption that natural-kind terms function just like proper names: they designate their referents directly and they are rigid designators: their reference is unchanged even in worlds in which the referent lacks some or all the properties associated with it in the actual world, and which are useful to us in identifying that referent. There have, however, been heated (...) debates about what should be taken as a natural-kind term. Some challenge the very existence of a separate category of natural-kind terms ; some their being directly referential ; some raise the possibility that direct reference extends to terms beyond those usually assumed to fall under the category, e.g. to ‘polemical’ terms. When these debates turn on the question of what natural kinds are, they take on a strong epistemological or metaphysical dimension. We think the issues can be clarified within the limits of the philosophy of language: by looking into what ranges of general terms are perceived by speakers as rigid designators of natural kinds. The first step to take is to ground the various kinds of semantic externalism in distinct brands of semantic deference. This we define as speakers’ being disposed to use words in line with the norms of their linguistic community and as consenting to being corrected when it is manifest that their use and understanding of a word does not match common practice. When those dispositions are present, speakers defer semantically to something beyond themselves. Here, our focus is on spotting the words for which speakers would defer not to the current usage of the word in the linguistic community, nor to the current experts of the field to which the word pertains, but ultimately to the very nature of the referent of the term. When speakers’ deference conforms to that pattern, we argue, that is evidence that indexical externalism provides the right metasemantic account of how the meaning of the word is determined. In other words, one can say that the word is treated like a natural-kind term. But how can patterns of deference be measured? In an ongoing survey, participants are confronted with conditions that may prompt them to revise certain classificatory statements, e.g. An emu is a bird. Each condition makes salient one of the targets we have identified for deference: the community usage, the experts, the ‘world as it is’. In the condition that seeks to tap into the latter kind of deference, participants are presented with a scenario in which future scientific discoveries result in excluding from the extension of a term certain members currently thought to fall under that extension, e.g. discoveries that require excluding certain species now thought to be birds from the Aves class. The scenario is such that it is clear that the ‘discoveries’ bring us closer to the actual essence, if there is one, of birds. Our reasoning is that, if participants significantly modify their statements in the light of that scenario, they can be taken to ‘defer’ to the nature of the referent, thus vindicating indexical externalism. We test if words not normally assumed to be natural-kind terms – for instance summer, contract or rape – exhibit patterns of deference similar to those for bird. If so, then there’s a case for an extension of indexical externalism beyond the usual set of terms. What would be shown in this way is that speakers have something like realist intuitions with respect to words whose meaning is usually taken to be purely conventional or polemical. We are at the pre-test stage for the survey. We cannot yet report on our results. We should, however, have initial results by March, which, we believe, will enrich the observations made by previous empirical studies. References: Braisby, N., Franks, B. & Hampton, J. 1996.

Children with autism spectrum disorder show marked difficulties in reading comprehension, a complex cognitive skill fundamental to successful daily functioning that is associated with core executive functions. However, the neurophysiological mechanisms underlying reading comprehension deficits in these children remain elusive. Twenty-one right-handed males with high-functioning ASD and 23 age-, IQ-, educational level-, sex- and handedness-matched typically developing individuals underwent a reading comprehension test and the semantic verbal fluency test that tapped core executive functions underlying reading comprehension during concurrent (...) prefrontal functional near-infrared spectroscopy measurement. Participants’ information processing efficiency was also assessed. High-functioning ASD children exhibited general reading comprehension [main effect of group: F = 7.58, p = 0.009], selective verbal fluency deficits [Group × category interaction: F = 4.90, p = 0.032] and slower processing speed. Regarding the hemodynamics of the prefrontal cortex, although ASD individuals showed comparable patterns of PFC brain activation to their healthy counterparts, lower PFC intrahemispheric [main effect of group: F = 11.36, p = 0.002] and interhemispheric [main effect of group: F = 7.79, p = 0.008] functional connectivity were evident during the semantic verbal fluency test. At the whole-group level, poorer reading comprehension performance was associated with poorer performance in the semantic verbal fluency test. Moreover, poorer semantic verbal fluency test performance was associated with slower information processing speed, which is associated with reduced left medial PFC functional connectivity. Abnormal intrahemispheric and interhemispheric prefrontal hypoconnectivity is associated with deficits in executive processes essential for reading comprehension in ASD. Our study has provided important implications for the neuropsychological and neurophysiological mechanisms underlying reading comprehension deficits in ASD. (shrink)

Recently, psychologists have developed indirect measurement procedures to predict suicidal behavior. A prominent example is the Death/Suicide Implicit Association Test (DS-IAT). In this paper, I argue that there is something special about the DS-IAT which distinguishes it from different IAT measures. I argue that the DS-IAT does not measure weak or strong associations between the implicit self-concept and the abstract concept of death. In contrast, assuming a goal-system approach, I suggest that sorting death-related to self-related words takes effort because (...) death-related words trigger avoidance-impulses, which suicide ideation weakens. The DS-IAT taps into weakened automatic responses from the self-preservation system. Additionally, the suggested cognitive structure, illuminated with the selfish-goal theory, explains predictable suicidal behavior. (shrink)

This article aims to further test the cognitive claims of the so-called subjectivity account of causal events and their linguistic markers, causal connectives. We took Mandarin Chinese, a language that is typologically completely different from the usual western languages, as a case to provide evidence for this subjectivity account. Complementary to the commonly used corpora analyses, we employed crowdsourcing to tap native speakers’ intuitions about causal coherence, focusing on four result connectives kějiàn ‘therefore’, suǒyǐ ‘so’, yīncǐ ‘so/for this reason’ (...) and yúshì ‘thereupon/as a result’. The analysis shows systematic differences regarding the use of connectives in relations that differ in terms of subjectivity, demonstrating that native speakers make use of subjectivity to encode and decode different types of causal relations in discourse. Moreover, our study evidences that a comprehensive model of subjectivity should include the epistemic dimension of certainty about the subjectivity scale that might be indicated by other linguistic elements. In-depth analyses of the test items revealed that the presence/absence of modality words in the result segments are related to different preferential patterns for the connectives. There is a trade-off between the epistemic dimension of certainty and the expression of subjectivity in the four connectives involved. (shrink)

IntroductionPrevious transcranial magnetic stimulation studies have revealed that the activity of the primary motor cortex ipsilateral to an active hand plays an important role in motor control. The aim of this study was to investigate whether the ipsi-M1 excitability would be influenced by goal-directed movement and laterality during unilateral finger movements.MethodTen healthy right-handed subjects performed four finger tapping tasks with the index finger: simple tapping task, Real-word task, Pseudoword task, and Visually guided tapping task. (...) In the Tap task, the subject performed self-paced simple tapping on a touch screen. In the real-word task, the subject tapped letters displayed on the screen one by one to create a Real-word. Because the action had a specific purpose, this task was considered to be goal-directed as compared to the Tap task. In the Pseudoword task, the subject tapped the letters to create a pseudoword in the same manner as in the Real-word task; however, the word was less meaningful. In the VT task, the subject was required to touch a series of illuminated buttons. This task was considered to be less goal-directed than the Pseudoword task. The tasks were performed with the right and left hand, and a rest condition was added as control. Single- and paired-pulse TMS were applied to the ipsi-M1 to measure corticospinal excitability and short- and long-interval intracortical inhibition in the resting first dorsal interosseous muscle.ResultsWe found the smaller SICI in the ipsi-M1 during the VT task compared with the resting condition. Further, both SICI and LICI were smaller in the right than in the left M1, regardless of the task conditions.DiscussionWe found that SICI in the ipsi-M1 is smaller during visual illumination-guided finger movement than during the resting condition. Our finding provides basic data for designing a rehabilitation program that modulates the M1 ipsilateral to the moving limb, for example, for post-stroke patients with severe hemiparesis. (shrink)

Perception and action are tightly coupled. However, there is still little recognition of how individual motor constraints impact perception in everyday life. Here we asked whether and how the motor slowing that accompanies aging influences the sense of visual speed. Ninety-four participants aged between 18 and 90 judged the natural speed of video clips reproducing real human or physical motion. They also performed a finger tapping task and a visual search task, which estimated their motor speed and visuospatial (...) attention speed, respectively. Remarkably, aged people judged videos to be too slow, as compared to younger people: the Point of Subjective Equality, which estimated the speed bias in the SoS task, was +4% in young adults, +12% in old adults and +16% in elders. On average, PSE increased with age at a rate of 0.2% per year, with perceptual precision, adjustment rate, and completion time progressively worsening. Crucially, low motor speed, but not low attentional speed, turned out to be the key predictor of video speed underestimation. These findings suggest the existence of a counterintuitive compensatory coupling between action and perception in judging dynamic scenes, an effect that becomes particularly germane during aging.

Cognitive and biological theories of emotion consider surprise as an emotional response to unexpected events. Four experiments examined the latency and the duration of one behavioural component of surprise: The interruption of ongoing action. Participants were presented with an unannounced visual event—the appearance of new perceptual objects—during the execution of a continuous action—a rapid alternate finger tapping—which allowed a precise measurement of the latency, and the duration of an action interruption induced by the surprising event. Of the participants, (...) 78% interrupted the tapping with a mean latency of 214 ms and a mean duration of 995 ms. Variations of the number and perceptual heterogeneity of the new objects revealed that the perceptual analysis of the surprising event contributes significantly to the interruption duration.

Hemodynamic response to motor execution (ME) and motor imagery (MI) was investigated using functional near-infrared spectroscopy (fNIRS). We used a 31 channel fNIRS system which allows non-invasive monitoring of cerebral oxygenation changes induced by cortical activation. Sixteen healthy subjects (mean-age 24.5 yeas) were recruited and the changes in concentration of hemoglobin were examined during right and left hand finger tapping tasks and kinesthetic MI. To suppress the systemic physiological interference, we developed a preprocessing procedure which prevents over-activated reporting (...) in NIRS-SPM. In the condition of ME, more activation was observed in the anterior part of the motor cortex including the pre-motor and supplementary motor area (pre-motor and SMA), primary motor cortex (M1) and somatosensory motor cortex (SMC; t (15) > 2.27), however, in the condition of MI, more activation was found in the posterior part of motor cortex including SMC ( t (15) > 1.81), which is in line with previous observations with functional magnetic resonance imaging (fMRI).

The potential benefits of priming intermittent theta burst stimulation with continuous theta burst stimulation have not been examined in regard to sensorimotor oscillatory activities recorded in electroencephalography. The objective of this study was to investigate the modulatory effect of priming iTBS delivered to the motor cortex on movement-related and mirror visual feedback -induced sensorimotor event-related desynchronization, compared with iTBS alone, on healthy adults. Twenty participants were randomly allocated into Group 1: priming iTBS—cTBS followed by iTBS, and Group 2: non-priming iTBS—sham (...) cTBS followed by iTBS. The stimulation was delivered to the right primary motor cortex daily for 4 consecutive days. EEG was measured before and after 4 sessions of stimulation. Movement-related ERD was evaluated during left-index finger tapping and MVF-induced sensorimotor ERD was evaluated by comparing the difference between right-index finger tapping with and without MVF. After stimulation, both protocols increased movement-related ERD and MVF-induced sensorimotor ERD in high mu and low beta bands, indicated by significant time effects. A significant interaction effect favoring Group 1 in enhancing movement-related ERD was observed in the high mu band [F = 4.47, p = 0.049], compared with Group 2. Our experiment suggests that among healthy adults priming iTBS with cTBS delivered to the motor cortex yields similar effects with iTBS alone on enhancing ERD induced by MVF-based observation, while movement-related ERD was more enhanced in the priming iTBS condition, specifically in the high mu band.

Exposure to environmental contextual changes, such as those occurring after an earthquake, requires individuals to learn novel routes around their environment, landmarks and spatial layout. In this study, we aimed to uncover whether contextual changes that occurred after the 2009 L’Aquila earthquake affected topographic memory in exposed survivors. We hypothesized that individuals exposed to environmental changes—individuals living in L’Aquila before, during and after the earthquake (hereafter called exposed participants, EPs)—improved their topographic memory skills compared with non-exposed participants (NEPs) who moved (...) to L’Aquila after the earthquake, as only EPs had to modify their previous cognitive map of L’Aquila. We also hypothesized that memory improvement was selective for the navigational space and did not generalize across other spatial and verbal domains. To test these hypotheses, we compared the topographic and spatial memory skills of 56 EPs without post-traumatic stress disorder (PTSD) symptoms to the skills of 47 NEPs using the Walking Corsi Test (WalCT; memory test in the navigational space) and the Corsi Block-Tapping Test (CBT; visuospatial memory test in the reaching space); EPs and NEPs were matched for gender, education and general navigational skills. A sub-group of participants also underwent the Rey-Auditory Verbal Learning Test (RAVLT; verbal memory test). The results showed that only EPs had better performances on topographic learning (TL) assessed using the WalCT rather than spatial learning assessed by the CBT. This outcome suggests the possibility that EPs specifically improved topographic memory. This effect may be due to continuous exposure to environmental changes that have required individuals to learn novel paths within the city and integrate novel information, such as “new towns,” into their pre-existing mental representation of the city. Implications and limitations of the study are discussed. (shrink)

Aphasia is an acquired impairment of language functions resulting from a brain lesion. It is usually accompanied by deficits in non-linguistic cognitive processes. This study aimed to investigate in patients with aphasia the complex interrelationships between selected cognitive functions: auditory speech comprehension, working memory, and temporal information processing in the millisecond time range. Thirty right-handed subjects aged from 27 to 82 years suffering from post-stroke aphasia participated in the study. Verbal working memory and spatial working memory were assessed with: a (...) receptive verbal test and the Corsi Block-Tapping Test, respectively. Both these WM tests used the forward tasks and backward tasks. Auditory comprehension was assessed by receptive language tests, and TIP efficiency was assessed by auditory perception of temporal order in the millisecond time range. We observed better performance of forward WM tasks than backward ones, independently of the type of material used. Furthermore, the severity of auditory comprehension impairment correlated with the efficiency on both forward and backward VWM tasks and the backward SWM task. Further analysis revealed that TIP plays a crucial role only in the latter task. These results indicate the divergent pattern of interactions between WM and TIP depending on the type of WM tasks. Level of verbal competency appeared to play an important role in both VWM tasks, whereas TIP appeared to be important for SWM, but only on the backward task. (shrink)

Sometimes I think: I'm flying. And why am I flying? Because of the dress. The flesh, I think, is multiplying itself. Here are the children, I think, going away from me and coming to me. If all is one, I think, why this split?My body of thought is likewise made of a womb of wombs. Whatever it begets begets its own body [in this sense I may be said to be multiparous].I am beautiful like a snip of ivory. My face (...) is like the negative of another woman's face. Whatever she does I do moving backward.I spread a hundred fingers up against the wind and the wind dries the lacquer. At these parties I have no given name. I may be called Flora and I may be called Rosamund. The images of color that I set up in space redeem me.In the morning. After the dreams. I see the white body stitched in bed. My corporal body. The veins that store the precious fluid. What I think have they hauled up there from the deep?I get up as in the miracle that Our Teacher Rabbi Loew worked upon a lump of clay and turn on the stove.Sometimes the light bounces off of forks and knives into the eyes. The light of the fork into the eye of the fork and the light of the knife into the eye of the knife.What am I what am I I am thinking flattening out knives and forks on those wooden headstones they call a table?The bread is the showbread and the butter is the clot of my blood. What are they looking for in these blue thighs?The kitchen windows [as in the ancient Icelandic language] are the wind's eye. This is the house and these are the children's table-napkins.... Now. When everything is in place. I am waterboiling. Water pours out of the mouth of the tap into the mouth of the kettle and I am thinking about these hairs that I have. About the hundreds of thousands of fine threads that rise at night in utter silence from the skin. The walls close in on me but my head. As in the Book of Creation. Extracts from nothingness black streams.Through the drinking glasses I see a great field of ice. A white antelope eating a fish.... What am I with a round shoulder and milk muttering prices of chemicals. The cash registers cut the boundaries of my skin.In supermarkets with thousands of tins of canned peas ought to ambulate people covered with hair. Let them block one another's cart like they once did in the hippodromes of Byzantium.Let them speak—with those colorful rags that they tie around their necks—into mouthpieces of telephones. Let their voices run crisscross like stifled crow calls between wires inside the earth. Why have they enclosed me—I, who can cover entire fields like Bermuda grass—within the confines of an electric bell?At 7:20. As if down the ladder of angels painted by Raphael. The child descends the wooden staircase. His toes are depressed precisely according to the divine image of grief. Each toe and its mirror reflection in the other foot.The forest creatures on the pajama fabric with their mouths gaping open as in the sudden vision seen by our primogenitor when they spread the coat of many colors before him and said: Surely he has been torn to pieces.... When the child turned inside me and stood in the placental fluid with his head to the ground, the two of us were the complete converse figure. One head toward the outer boundary, the other head toward the middle point.It was unnatural how the head emerged. Why did it pierce the membrane in which it was enfolded and discharge the water?Windows previously shut were torn apart. Lids of cookware dropped to the floor. This rupture [Michael. Michael.] gave birth to unreason.The child [in my imaginations he is chasing gadflies] is sitting at the table waiting for his cornflakes. He is eating them flake by flake and inside every flake are little crystals of sugar.This game [being able to hold shreds of sugar inside tiny dents] fills his heart.... The light that radiates in every thing is the light of late autumn. I play with it the age-old game. Ask for its name and it replies.The kitchenware too bear their names [just as they bear the form].... I can write an inner play about The Non-Intervention of Time in Kitchenware. Time will get the leading role.In Act One it will set out [like Ulysses] on a journey. The kitchenware will stay put, each ware in its respective place, within daily life.In Acts Two and Three time will travel so far that one or two wares should drop out of place.Act Four will be called Fatal Incidence and Act Five, The Return of Time.... I shout [an inner shout] Dolores Dolores as if I had a friend whose name were like that.How do you do Dolores [I say in my heart] and exchange recipes for dresses with her.Then Dolores sets out in both directions at once. The direction of the great bird in the sky and the direction of Nachlat Binyamin St.... I can see [by means of two mirrors] my silk dressing gown.The silk dressing gown enfolds me and prepares me for verbal exchange. It enables me to communicate information. If it slides down I kneel down until it slides up [and then I kneel down].... When I think of recollection I wonder how the image of myself gets duplicated.The bathtub gets duplicated and the light above the bathtub. Time sends a facsimile of itself.In the black margins outside the sheet of paper hides my mother. Come out come out she is calling to me like you would to a snail.At that time were created the archetypes of things.The complete washbasin. The complete mirror. Next to every sound was inscribed the right clef.Every movement was a perfectum mobile: I jump and by force of this jump I jump again.... Through the window I see the crow called Salpeter.Good morning Old Salpeter. Did you get your black robe back from the dry cleaner?Sometimes you see me obliquely from the right and sometimes obliquely from the left. What am I? A very strange female crow?I adore your rich language. This single word of yours that has in it all the verb stems.... What is so logical about the sky? The window frame.The window frame is like the twelve apostles. Three in each lintel and in their midst [behind the nebula] is sitting the child Michael.The motion of a doll turned over and the motion of the trains sent by him flying in the air are the divine edict. Get'p get'p he tells me all of you and go'ver there.... See Dolores how simple everything is: There is the kitchen. There is the child. There is the wooden staircase.Whom are we to thank for this grace. The colors are so right Dolores and the shapes precise. Every thing I spell out is cut with utmost perfection for the space allotted to it and for the sequence of time.... My biography may easily be canceled.First cancel the alienation. Then cancel the kneeling in the dark. The joy of the assigned date. The bridal veil and the porcelainware.If a medical ground is required I can say I have edema.... I like the words earth quake.Sometimes I think the earth is quaking and the words are not and sometimes the words are quaking and the earth is not.The great catfish know the earth is about to quake and the Chinese who paint the words with a fine paintbrush six lines for the earth and fifteen for this quake set guards to watch the great catfish who knows what is about to take place.... As if after a very severe accident I have to practice life anew.My physiotherapist tells me: Now a slight movement with the right hand. Now a shake of the head.I learn to press handles. To turn sharply in this or that direction.Lately when they ask me anything I pretend that the reply answers the question.Look Dolores how I refute the theory about the formation of species:I take a bubble of soap from the sink and elevate it to the sun.... There is a thing Dolores and it is infinitely good and I shall not tell you what it is.You can hear it in the first hours of the night when darkness is gaping. It has the property of withdrawing into a point tiny as a tittle.Or you can search for it in places where there appears to be something and there is not. (shrink)

Many experiments with infants suggest that they possess quantitative abilities, and many experimentalists believe that these abilities set the stage for later mathematics: natural numbers and arithmetic. However, the connection between these early and later skills is far from obvious. We evaluate two possible routes to mathematics and argue that neither is sufficient: (1) We first sketch what we think is the most likely model for infant abilities in this domain, and we examine proposals for extrapolating the natural number concept (...) from these beginnings. Proposals for arriving at natural number by (empirical) induction presuppose the mathematical concepts they seek to explain. Moreover, standard experimental tests for children's understanding of number terms do not necessarily tap these concepts. (2) True concepts of number do appear, however, when children are able to understand generalizations over all numbers; for example, the principle of additive commutativity (a+b=b+a). Theories of how children learn such principles usually rely on a process of mapping from physical object groupings. But both experimental results and theoretical considerations imply that direct mapping is insufficient for acquiring these principles. We suggest instead that children may arrive at natural numbers and arithmetic in a more top-down way, by constructing mathematical schemas. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Figuring Myself Out:Certainty, Injury, and the Poststructuralist Repositioning of Bodies of IdentityJames Haywood Rolling Jr. (bio)CertaintyI have been attempting to figure myself out. Out of chaos and incompletion, toward increased certainty. I have been at this task of construction for quite some time now. I have just proposed my dissertation and my intentions are once again uncertain. My dissertation is to be a self-study. It is also a story (...) about uncertainty and my attempts to redeem a clear definition, to be named a peer and a colleague among artists, writers, and teachers. I have been uncertain as a little boy; uncertain as a son; uncertain as a student of architecture; uncertain as an artist and writer; uncertain as a teacher; uncertain as a black man. To compensate, I have sought the conferral of certainty, a name among leaders in many fields of inquiry. Still, it is not easy to forget that certainty has also been the cause of great injury to my body, to my mind.On sunny afternoons after school all the kids came outside to play. The air would fill with echoes going back and forth between the red brick and stone buildings on both sides of our narrow street. Pounding rubber balls, the taps and scratches of shoe heels, and the slapping of sneakers on the cement and asphalt.Sometimes white chalk would appear and hopscotch boxes were quickly drawn on the neat squares of cement pavement in front of my Grandma's house. Grandma lived next door to us. Houses on our block were side by side, sharing each other's walls.On a particular day, similar to other days, I watched as a small flat stone was tossed to bounce across the cement into a numbered box. I watched the one foot, two feet, one foot hops from box to box to stop and balance on one small hopping foot, steadying itself, to drop a hand to pick up the stone. Some little girl came to sit beside me and asked me to look at her. We were sitting on one of Grandma's two wooden benches, just inside the front gate. [End Page 46] Two steps down was the sidewalk and other kids. I ignored the girl. I made sure my body had no contact with hers on the bench. Why was she talking to me anyway? Didn't she see I didn't have anything I wanted to say?"Look at me!" she said, tugging at my arm."Will you stop it!" I snapped back, jerking my arm away. Being touched was not natural to me. My family didn't touch. I tightened the skin of my eyebrows and the bridge of my nose into a frown."Smile!" the little girl said slyly, trying to tickle me."Leave me alone!" I yelled. I tried to move away from the touching.I must have grinned. Grinning relaxes the frowns on faces. The girl clapped a hand over her mouth, all giggles. I asked what she was laughing so loud for. The kids out in front of us now had our attention. I felt like I was now being watched. I can't remember the faces, just the noise and voices that seemed to stop. The little girl stood up, pointed at my face and declared, finger in my face, pointing, speaking out loud, "Look! He only has one dimple! See?! Look at his face!""No I don't," I said, dropping my face, my eyes, my voice. My head was down and I didn't want to see if anyone was looking. The attention made my face warm and I needed to move away fast. "No I don't," I repeated, stiffly. My whole head seemed to glow brightly, very hot, drawing lots of attention. I was beneath windows, very near, on both sides of the street, always with onlookers. I rushed through the painted iron gate, going quickly next door, upstairs to "our house," to the second floor apartment we lived in, down the hallway so dark after the bright outside, around a curve and a corner, into the bathroom, closing the door behind me.

Individuals typically produce auditory sequences, such as speech or music, at a consistent spontaneous rate or tempo. We addressed whether spontaneous rates would show patterns of convergence across the domains of music and language production when the same participants spoke sentences and performed melodic phrases on a piano. Although timing plays a critical role in both domains, different communicative and motor constraints apply in each case and so it is not clear whether music and speech would display similar timing mechanisms. (...) We report the results of two experiments in which adult participants produced sequences from memory at a comfortable spontaneous (uncued) rate. In Experiment 1, monolingual pianists in Buffalo, New York engaged in three production tasks: speaking sentences from memory, performing short melodies from memory, and tapping isochronously. In Experiment 2, English-French bilingual pianists in Montréal, Canada produced melodies on a piano as in Experiment 1, and spoke short rhythmically-structured phrases repeatedly. Both experiments led to the same pattern of results. Participants exhibited consistent spontaneous rates within each task. People who produced one spoken phrase rapidly were likely to produce another spoken phrase rapidly. This consistency across stimuli was also found for performance of different musical melodies. In general, spontaneous rates across speech and music tasks were not correlated, whereas rates of tapping and music were correlated. Speech rates (for syllables) were faster than music rates (for tones) and speech showed a smaller range of spontaneous rates across individuals than did music or tapping rates. Taken together, these results suggest that spontaneous rate reflects cumulative influences of endogenous rhythms (in consistent self-generated rates within domain), peripheral motor constraints (in finger movements across tapping and music), and communicative goals based on the cultural transmission of auditory information (slower rates for to-be-synchronized music than for speech).

BackgroundAdults with ADHD exhibit a neuropsychological profile that may present deficits in many cognitive domains, particularly attention and executive functions. However, some authors do not consider executive disfunction as an important part of the clinical profile of the syndrome; this could be related to the use of inappropriate neuropsychological tests, probably not adapted and not sufficiently ecological. Moreover, new data are required on specific correlation of attentive-executive symptoms with socio-demographic factors. Therefore, the aim of this study is to analyze the (...) neuropsychological performance of a group of adults with ADHD, also evaluating the influence of gender, age and education level.MethodsWe retrospectively collected health-related personal data of 40 adult ADHD patients, clinically diagnosed and evaluated via a battery of 4 neuropsychological tests and 1 self-administered questionnaire. Gender, age and years of education differences were assessed.ResultsAttention and EFs deficits have been highlighted mainly on the d2-R and 5-point neuropsychological tests, which therefore seem to be more sensitive in measuring the attention-executive dysfunction in an adult ADHD population, than TAP Go/No-go and ROCFT. ADHD patients also manifested subjective behavioral impulsivity disorders on BIS-11. There were no statistically significant gender differences in cognitive performance. On the contrary, younger patients performed worse on subscales TAP Go/No-go errors and 5-points number of drawings, while participants with a higher education level performed better on subscales d2-R speed of execution and d2-R errors. This supports a reduction in the number of errors and the execution time as a function of older age and a higher level of education. Finally, patients with higher education also self-reported greater impulsivity in planning.ConclusionOur preliminary findings suggest that adult ADHD is not a lifelong stable disorder, but it may change over time. Moreover, attention-executive deficits may be influenced and partially counterbalanced by experience and a higher level of education. This could underlie the development of specific psycho-behavioral and cognitive compensatory strategies. The use of self-administered questionnaires is therefore recommended to highlight attentional and executive difficulties that may not result in neuropsychological tests. (shrink)

In a recent study (Chen et al., 2018), we conducted a series of experiments that induced the “four-hand illusion”: using a head-mounted display (HMD), the participant adopted the experimenter’s first-person perspective (1PP) as if it was his/her own 1PP. The participant saw four hands via the HMD: the experimenter’s two hands from the adopted 1PP and the subject’s own two hands from the adopted third-person perspective (3PP). In the active four-hand condition, the participant tapped his/her index fingers, imitated by the (...) experimenter. Once all four hands acted synchronously and received synchronous tactile stimulations at the same time, many participants felt as if they owned two more hands. In this paper, we argue that there is a philosophical implication of this novel illusion. According to Merleau-Ponty (1945/1962) and Legrand (2010), one can experience one’s own body or body-part either as-object or as-subject but cannot experience it as both simultaneously, i.e., these two experiences are mutually exclusive. Call this view the Experiential Exclusion Thesis. We contend that a key component of the four-hand illusion—the subjective experience of the 1PP-hands that involved both “kinesthetic sense of movement” and “visual sense of movement” (the movement that the participant sees via the HMD)—provides an important counter-example against this thesis. We argue that it is possible for a healthy subject to experience the same body-part both as-subject and as-object simultaneously. Our goal is not to annihilate the distinction between body-as-object and body-as-subject, but to show that it is not as rigid as suggested by the phenomenologists. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:On the NoseDavid F. Bell (bio)I recently underwent a COVID test. As the technician inserted the rather ominous cotton-tipped probe into my nostril, she told me that it was going to feel as if she were tickling my brain. Indeed… This experience, shared by many during the past three years, and likely multiple times, prompted me to think about my nose. Not since cocaine reentered American mainstream culture (...) in the 1970s and '80s—and found its way into countless movies that reflect the trend—has the nose been so central to a certain state of public life. It's difficult to find a film dealing with American culture from that period and beyond, from Scarface to The Wolf of Wall Street, in which there is not a scene depicting characters snorting the obligatory line or spoon of cocaine. Yes, snorting, sniffing, sneezing, ingesting the line through the nose and finishing leftover dust by collecting it with a moist finger, rubbing it lovingly against the front gum of the mouth. Freud's "Über Coca" looms ominously in the background, the work of a phase in Freud's professional career complicated by his obscure relationships with Parke-Davis (now a subsidiary of Pfizer) and Merck, pharmaceutical companies that supplied him with early samples to tickle his nose (Freud; Merkel). The Sacklers of the moment. In our day, Pfizer wants to transform our noses into defenses against the virus rather than conduits toward mind-altering dreams. In the wake of the Freud and William Halsted cocaine addictions chronicled by Howard Merkel, the irony of the contemporary link between Pfizer and the nose is patent.The nose: that orifice through which the virus creeps, the first stage in breathing, the first filter for air-borne pollutants. Recently, important immunological analyses of COVID have focused on the question of viral load, how much virus is necessary to overcome the nose's filtering function and reach the deeper airways leading to the lungs. The processes triggered by any of the major vaccines prepare antibody blueprints and actual antibodies that can be dispatched to the linings of the nose to counter the virus as soon as the body detects its presence. The Delta, Omicron, and subsequent variants remind us that the virus has mechanisms to challenge this response, namely, increased viral load that intensifies transmissibility and the potential to overwhelm antibodies. It seems, however, that [End Page 231] so-called breakthrough infections are still well controlled by the body's vaccinated immune system. Hysteria about the dangers of such incursions is partially a product of biased and often incorrect or incomplete media coverage of the COVID vaccine, which has terrified the vaccinated and fueled the skepticism of the unvaccinated.The virus tries to overpower and confuse the filtering nose in another way, more immediately apparent to our conscious selves. As many as eighty-five percent of COVID infections result in the loss of smell, generally recovered in about two to three weeks in sickened people who overcome the infection. About five percent of COVID victims, however, have not recovered their sense of smell six months or more after they have shed the virus.1 What might it mean to lose one's sense of smell? In our vision-oriented culture, both sound (the ear) and smell (the nose) have been less recognized as primary defense mechanisms than in other cultures. When one hears a sound, the first reaction is to prepare for a threat, before the sonic source is seen or understood. Orientation in the world, knowing from which direction the sound emanates, is key to preparing the body for an encounter with an unknown phenomenon: "To sound (an alarm) means to warn. Isn't any emerging sound understood as a warning? Any unexpected sonic occurrence is seen as an indication of something that is to come and that must be clarified rapidly" (Deshays 34). By the same token, to sample surroundings by sniffing what is in the air signals whether one should inhale or somehow try to hold one's breath in search of cleaner, more palatable air. Without olfaction, we are at potentially heightened risk of asphyxiation. We are more likely to... (shrink)

Change is the new normal, but so it has been for ages. Experience to navigate change is something you get just after you needed it, unless you tap into age-old experience. The Fourth Industrial Revolution (4IR) is bringing about wide-ranging changes. With people having to adjust, the question is whether Christianity, with its roots in preindustrial times, may support people to navigate these changes. This conceptual article focusses on the relationships amongst constructs, exploring logical arguments about how these constructs are (...) associated. The 4IR is briefly described from differing vantage points, as to whether it is a valid description thereof. Whether a revolution or evolution, it is a complex system, and therefore the theory of complex systems is used, with the conclusion that one may merely participate in such systems. Being novel situations, one needs to participate creatively, based on a cognitive understanding of creativity. Creative solutions do not materialise out of thin air but are the novel use of existing knowledge structures. Christian traditions include institutional memories of how people managed situations of radical change, as reflected in Genesis 1 and Lamentations 4. These passages provide building blocks that may be used in creative coping strategies during times of change. Both passages suggest the strategy to juxtapose order and chaos, and borrowing from that, a ‘Grip-Grapple-Grow’ scaffolding system is suggested. To test the usability thereof, the issue of face masks during the Coronavirus Disease 2019 pandemic was touched upon, to evaluate how the interplay amongst 4IR, disruption, (Christian) beliefs and technological advancement may play out. Contribution: The Fourth Industrial Revolution is speeding up the pace of change, with people having to adapt. This article explores processes of change management, juxtaposing the theory of complex systems, the cognitive science understanding of creativity and institutional memories afforded by some Christian traditions reflecting on how people managed order and chaos.

(b) the mitball (static light) was the representative sample that provoked much eye contact, produced satisfactory reactions to activities,; (c) the quality of fluorescence enhanced the levels of pleasure and the reactions to the activity. We propose that dynamic and reflective materials can be adopted to divert the attention of children, and fluorescent toys can then employed to sustain parent-child interaction. (shrink)

Life history theory is a fruitful source of testable hypotheses about human individual differences. However, this field of study is beset by unresolved debates about basic concepts and methods. One of these controversies concerns the usefulness of instruments that purport to tap a unidimensional life history factor based on a set of self-reported personality, social, and attitudinal variables. Here, we take a novel approach to analyzing the psychometrics of two variants of the Arizona Life History Battery: the Mini-K and the (...) K-SF-42. Psychological network analysis generates models in which psychological variables comprise the nodes of a network, while partial correlation coefficients between these variables comprise the edges of the network. Centrality indices operationalize each node’s importance based on the pattern of the connections in which that node plays a role. Because childhood environments are hypothesized to influence adult LH, we tested the hypothesis that among the Mini-K items, and the K-SF-42 scales, those that tap relationships with parents are central to the networks constructed from these instruments. In an MTurk sample and an undergraduate sample that completed the Mini-K, and an MTurk sample that completed the K-SF-42, this hypothesis was falsified. Indeed, the “relationships with parents” items were among the most peripheral in all three networks. We propose that network analysis, as an alternative to latent variable modeling, offers considerable potential to test hypotheses about the input-output mappings of specific evolved psychological mechanisms.

Two decades ago, the introduction of the Implicit Association Test (IAT) sparked enthusiastic reactions. With implicit measures like the IAT, researchers hoped to finally be able to bridge the gap between self-reported attitudes on one hand and behavior on the other. Twenty years of research and several meta-analyses later, however, we have to conclude that neither the IAT nor its derivatives have fulfilled these expectations. Their predictive value for behavioral criteria is weak and their incremental validity over and above (...) self-report measures is negligible. In our review, we present an overview of explanations for these unsatisfactory findings and delineate promising ways forward. Over the years, several reasons for the IAT’s weak predictive validity have been proposed. They point to four potentially problematic features: First, the IAT is by no means a pure measure of individual differences in associations but suffers from extraneous influences like recoding. Hence, the predictive validity of IAT-scores should not be confused with the predictive validity of associations. Second, with the IAT, we usually aim to measure evaluation (“liking”) instead of motivation (“wanting”). Yet, behavior might be determined much more often by the latter than the former. Third, the IAT focuses on measuring associations instead of propositional beliefs and thus taps into a construct that might be too unspecific to account for behavior. Finally, studies on predictive validity are often characterized by a mismatch between predictor and criterion (e.g., while behavior is highly context-specific, the IAT usually takes into account neither situation nor domain). Recent research, however, also revealed advances addressing each of these problems, namely (1) procedural and analytical advances to control for recoding in the IAT, (2) measurement procedures to assess implicit wanting, (3) measurement procedures to assess implicit beliefs, and (4) approaches to increase the fit between implicit measures and behavioral criteria (e.g., by incorporating contextual information). Implicit measures like the IAT hold an enormous potential. In order to allow them to fulfill this potential, however, we have to refine our understanding of these measures, and we should incorporate recent conceptual and methodological advancements. This review provides specific recommendations on how to do so. (shrink)
