Three experiments are reported which show that in certain contexts subjects reject instances of the valid modus ponens and modus tollens inference form in conditional arguments. For example, when a conditional premise, such as: If she meets her friend then she will go to a play, is accompanied by a conditional containing an additional requirement: If she has enough money then she will go to a play, subjects reject the inference from the categorical premise: She meets her friend, to the (...) conclusion: She will go to a play. Other contexts suppress the conditional fallacies. The first experiment demonstrates the effects of context on conditional reasoning. The second experiment shows that the inference suppression disappears when the categorical premise refers to both of the antecedents, such as: She meets her friend and she has enough money. In this case, subjects make both the valid inferences and the fallacies, regardless of the contextual information. The third experiment establishes that when subjects are given general information about the duration of a situation in which a conditional inducement was uttered, such as: If you shout then I will shoot you, they reject both the valid inferences and the fallacies. The results suggest that the interpretation of premises plays an even more central role in reasoning than has previously been admitted. Trois expériences montrent que dans certains contextes les sujets rejettent des instances valides de modus ponens et de modus tollens dans des énoncés conditionnels. Par exemple, quand une prémisse conditionnelle comme: Si elle rencontre son ami, alors elle ira jouer, est accompagnée par une phrase contenant une condition supplémentaire: Si elle a assez d'argent, alors elle ira jouer, les sujets rejettent l'inférence liant la prémisse catégorielle: Elle rencontre son ami, à la conclusion: Elle ira jouer. D'autres contextes éliminent également les inférences conditionnelles fallacieuses. La premiére expérience démontre l'effet du contexte sur la raisonnement conditionnel. La deuxiéme expérience montre que la suppression de l'inférence disparait quand la prémisse catégorielle fait référence aux deux antécédants, comme: Elle rencontre son ami et elle a assez d'argent. Dans ce cas, les sujets font aussi bien les inférences valides et fallacieuses, quelle que soit l'information contextuelle. La troisiéme expérience établit que quand l'on donne aux sujets des informations générales à propos de la durée d'une situation dans laquelle une conditionnelle a été prononcée, comme Si tu cries, alors je te tire dessus, ils rejettent autant les inférences valides que les inférences fallacieuses. Ces résultats suggèrent que l'interprétation des prémisses joue un rŏle encore plus central dans le raisonnement que l'on admettait auparavant. (shrink)

Recently, a new method of considering successful intentional thought suppression has emerged. This method, the think/no-think paradigm has been utilized over a multitude of settings and has fairly robustly demonstrated the ability to interfere with memory recall. The following experiment examined the effect of intentional thought suppression on recognition memory of nonverbalizeable shapes. In this experiment, participants learned word–shape targets. For some of the pairs, they rehearsed the shape when presented with the word; for others, they suppressed the (...) shape when presented with the word. Finally, participants were shown multiple shapes, one at a time, and asked to identify which they had previously seen as paired with a word. Results of the experiment indicated that, similar to results involving words, participants were less accurate in identifying suppressed shapes, as compared to rehearsed shapes. Implications of these findings are discussed. (shrink)

This chapter focuses on one of the common fallacies in Western philosophy called the suppressed evidence. This fallacy is as simple as it seems: one commits the fallacy when one presents evidence or an argument for a position but leaves out (or suppresses) relevant evidence that would weaken or show false one's conclusion. Suppression of evidence is commonly found in the (mis)presentation of statistics. Suppression of evidence is most common among conspiracy theorists. The fallacy of suppressing the evidence (...) can come from left, right, or center. According to The Skeptics Dictionary, scientists sometimes do it, reporters do it, and pretty much everybody does it now and again. It is an extremely effective way to make one's argument appear stronger than it is. But those interested in the truth should always present all the evidence they can, regardless of whether it hurts or hinders what they want to believe. (shrink)

We examine two competing effects of beliefs on conditional inferences. The suppression effect occurs for conditionals, for example, “if she watered the plants they bloomed,” when beliefs about additional background conditions, for example, “if the sun shone they bloomed” decrease the frequency of inferences such as modus tollens (from “the plants did not bloom” to “therefore she did not water them”). In contrast, the counterfactual elevation effect occurs for counterfactual conditionals, for example, “if she had watered the plants they (...) would have bloomed,” when beliefs about the known or presupposed facts, “she did not water the plants and they did not bloom” increase the frequency of inferences such as modus tollens. We report six experiments that show that beliefs about additional conditions take precedence over beliefs about presupposed facts for counterfactuals. The modus tollens inference is suppressed for counterfactuals that contain additional conditions (Experiments 1a and 1b). The denial of the antecedent inference (from “she did not water the plants” to “therefore they did not bloom”) is suppressed for counterfactuals that contain alternatives (Experiments 2a and 2b). We report a new “switched‐suppression” effect for conditionals with negated components, for example, “if she had not watered the plants they would not have bloomed”: modus tollens is suppressed by alternatives and denial of the antecedent by additional conditions, rather than vice versa (Experiments 3a and 3b). We discuss the implications of the results for alternative theories of conditional reasoning. (shrink)

Introduction: Pathological tremor is the most common motor disorder in adults and characterized by involuntary, rhythmic muscular contraction leading to shaking movements in one or more parts of the body. Functional Electrical Stimulation and biomechanical loading using wearable orthoses have emerged as effective and non-invasive methods for tremor suppression. A variety of upper-limb orthoses for tremor suppression have been introduced; however, a systematic review of the mechanical design, algorithms for tremor extraction, and the experimental design is still missing.Methods: (...) To address this gap, we applied a standard systematic review methodology to conduct a literature search in the PubMed and PMC databases. Inclusion criteria and full-text access eligibility were used to filter the studies from the search results. Subsequently, we extracted relevant information, such as suppression mechanism, system weights, degrees of freedom, algorithms for tremor estimation, experimental settings, and the efficacy.Results: The results show that the majority of tremor-suppression orthoses are active with 47% prevalence. Active orthoses are also the heaviest with an average weight of 561 ± 467 g, followed by semi-active 486 ± 395 g, and passive orthoses 191 ± 137 g. Most of the orthoses only support one DOF. Two-DOF and three-DOF orthoses account for 33 and 18%, respectively. The average efficacy of tremor suppression using wearable orthoses is 83 ± 13%. Active orthoses are the most efficient with an average efficacy of 83 ± 8%, following by the semi-active 77 ± 19%, and passive orthoses 75 ± 12%. Among different experimental setups, bench testing shows the highest efficacy at 95 ± 5%, this value dropped to 86 ± 8% when evaluating with tremor-affected subjects. The majority of the orthoses measured voluntary and/or tremorous motions using biomechanical sensors. Only one system was found to utilize EMG for tremor extraction.Conclusions: Our review showed an improvement in efficacy of using robotic orthoses in tremor suppression. However, significant challenges for the translations of these systems into clinical or home use remain unsolved. Future challenges include improving the wearability of the orthoses, and user control interfaces. We also suggest addressing non-technical challenges to make the technology more accessible. (shrink)

Participants scoring high and low on a measure of repressive coping style (Mendolia, 2002) first learned a series of related word pairs (cue–target). Half of the cues were homographs. In the subsequent think/no-think phase (Anderson & Green, 2001), they responded with targets on some trials and suppressed thoughts of targets on others. Suppressed targets were always emotionally negative, as were targets associated with baseline cues reserved for the final test. Some participants were provided with emotionally benign or positive substitutes to (...) help them suppress, and these substitutes were related to different meanings of the homographic cues, compared to those established by the targets. On the final test, all cues were presented for target recall. Only the repressors significantly benefited from the provision of positive substitutes to aid forgetting of the negative targets, regardless of the nature of the cues. (shrink)

The suppression task challenges classical logic. Classical logic is monotonic. However, in the suppression task, an inference with the form of modus ponendo ponens is inhibited by adding a new premise. Several explanations have been given to account for this fact. The present paper indicates three of them as examples: that of the theory of mental models, that based on logic programming and closed world assumption, and that referring to Carnap's concept of state‐descriptions. Besides, the paper offers one (...) more explanation linked to Carnap's idea of reduction. It proposes sentences akin to a reduction sentence, a pair reduction, and a bilateral reduction sentence. Those sentences are related to the initial conditional in the suppression task. This proposal tries to stay within first‐order predicate logic. (shrink)

Regulations implemented by World Athletics (WA) require female athletes with differences of sexual development to suppress their blood testosterone levels in order to participate in certain women’s sporting competitions. These regulations have been justified by reference to fairness. In this paper, we reconstruct WA’s understanding of fairness, which requires a “level playing field” where no athlete should have a significant performance advantage based on factors other than talent, dedication, and hard work over an average athlete in their category. We demonstrate (...) that by placing regulations only on testosterone levels, while ignoring physical as well as socioeconomic advantages, WA consistently fails to meet its own definition of fairness. We then discuss several ways in which this definition could be met. Our analysis shows that a categorical system, in which athletes are divided into categories based on properties leading to significant performance advantages, is best suited for meeting WA’s definition of fairness.

The suppression of the Modus Ponens inference is described as a loss of confidence in the conclusion C of an argument ''If A1 then C; If A2 then C; A1'' where A2 is a requirement for C to happen. It is hypothesised that this loss of confidence is due to the derivation of the conversational implicature ''there is a chance that A2 might not be satisfied'', and that different syntactic introductions of the requirement A2 (e.g., ''If C then A2'') (...) will lead to various frequencies in the derivation of this implicature, according to previous studies in the field of causal explanation. An experiment is conducted, whose results support those claims. Results are discussed in the light of the Mental Logic and Mental Model theories, as well as in the light of the pragmatic approach to uncertain reasoning. (shrink)

Consciously attempting not to think about something is a mental control strategy known as thought suppression. This strategy can be successful under certain conditions, but it often promotes an increase in the accessibility of the thought to consciousness, and along with this, a number of ironic processes and unwanted effects.

Key Words mental control, intrusive thought, rebound effect, ironic processes Abstract Although thought suppression is a popular form of mental control, research has indicated that it can be counterproductive, helping assure the very state of mind one had hoped to avoid. This chapter reviews the research on suppression, which spans a wide range of domains, including emotions, memory, interpersonal processes, psychophysiological reactions, and psychopathology. The chapter considers the relevant methodological and theoretical issues and suggests directions for future research.

Byrne has demonstrated that although subjects can make deductively valid inferences of the modus ponens and modus tollens forms, these valid inferences can be suppressed by presenting an appropriate additional premise “If R then Q” with the original conditional “If P then Q”. This suppression effect challenges the assumption of all syntactic theories of conditional reasoning that formal rules of inference such as modus ponens is part of mental logic. This paper argues that both the syntactic and the mental (...) model accounts of the suppression effect are inadequate because they fail to give a principled account of the critical interpretive component involved in reasoning. In contrast, the relative salience model proposed in this study emphasized the centrality of the interpretative processes with the critical component being the relative salience of premises as judged by subjects on the basis of their prior knowledge activated in particular problem situations. Using 120 undergraduates and 120 policemen as subjects, predictions from the model were tested and confirmed in a suppression paradigm and evidence of convergent validity for the construct of salience were obtained. The results cannot be reconciled with either the syntactic view or the mental model view that have dominated theories of conditional reasoning. (shrink)

Self-reported lost memory of child sexual abuse (CSA) can be mistaken for “repressed memory.” Based on our longitudinal studies of memory and disclosure in child maltreatment victims who are now adults, we discuss findings relevant to “repressed memory cases.” We examined relations between self-report of temporarily lost memory of CSA (subjective forgetting) and memory accuracy for maltreatment-related experiences (objective memory). Across two studies involving separate samples, we find evidence for memory suppression rather than repression: (1) Most adults who claimed (...) temporary lost memory of CSA reported memory suppression and clarified that they could have remembered the event if asked; (2) subjective forgetting was positively associated with accurate objective memory for maltreatment-related experiences. Subjective forgetting was also related to increased adult trauma symptoms and related to childhood non-disclosure of CSA. Moreover, trauma-related psychopathology mediated the relation between non-disclosure and subjective forgetting. Implications for psychological theory and repressed memory cases are discussed.

Modus ponens is the argument from premises of the form If A, then B and A to the conclusion B. Nearly all participants agree that the modus ponens conclusion logically follows when the argument appears in this Basic form. However, adding a further premise can lower participants’ rate of agreement—an effect called suppression. We propose a theory of suppression that draws on contemporary ideas about conditional sentences in linguistics and philosophy. Semantically, the theory assumes that people interpret an (...) indicative conditional as a context-sensitive strict conditional: true if and only if its consequent is true in each of a contextually determined set of situations in which its antecedent is true. Pragmatically, the theory claims that context changes in response to new assertions, including new conditional premises. Thus, the conclusion of a modus ponens argument may no longer be accepted in the changed context. Psychologically, the theory describes people as capable of reasoning about broad classes of possible situations, ordered by typicality, without having to reason about individual possible worlds. The theory accounts for the main suppression phenomena, and it generates some novel predictions that new experiments confirm. (shrink)

The Think/No-Think (T/NT) task was designed to test whether the deliberate avoidance of retrieving a memory (i.e., suppression) hinders the subsequent recall of that memory. Forgetting effects obtained with the T/NT-task (Suppression-Induced Forgetting) are thought to result from memory inhibition: the deactivation of the representation of the to-be-suppressed memory. Memory inhibition can be specifically inferred from decreased performance on a test using Independent Probes—cues that are unrelated to the initial study phase in the T/NT-procedure. The present contribution explores (...) the evidence for the idea that Suppression-Induced Forgetting obtained with such Independent Probes may provide a viable model for repression.A review of the literature on Suppression-Induced Forgetting with Independent Probes (SIF-IP) suggests that reliable estimates of the overall effect size are unavailable, that the extent to which the literature suffers from publication bias is unknown and that reporting bias may obstruct a clear view of the percentage of studies that find a statistically significant effect. In addition, it is difficult to study SIF-IP in autobiographical memories, due to their complexity and idiosyncrasy. All in all, it seems questionable whether suppression-induced forgetting obtained with independent probes provides a viable model of repression. (shrink)

‘Type’ in biology is a polysemous term. In a landmark article, Paul Farber (Journal of the History of Biology 9(1): 93–119, 1976) argued that this deceptively plain term had acquired three different meanings in early nineteenth century natural history alone. ‘Type’ was used in relation to three distinct type concepts, each of them associated with a different set of practices. Important as Farber’s analysis has been for the historiography of natural history, his account conceals an important dimension of early nineteenth (...) century ‘type talk.’ Farber’s taxonomy of type concepts passes over the fact that certain uses of ‘type’ began to take on a new meaning in this period. At the closing of the eighteenth century, terms like ‘type specimen,’ ‘type species,’ and ‘type genus’ were universally recognized as referring to typical, model members of their encompassing taxa. But in the course of the nineteenth century, the same terms were co-opted for a different purpose. As part of an effort to drive out nomenclatural synonymy – the confusing state of a taxon being known to different people by different names – these terms started to signify the fixed and potentially atypical name-bearing elements of taxa. A new type concept was born: the nomenclatural type. In this article, I retrace this perplexing nineteenth century shift in meaning of ‘type.’ I uncover the nomenclatural disorder that the new nomenclatural type concept dissolved, and expose the conceptual confusion it left in its tracks. What emerges is an account of how synonymy was suppressed through the coinage of a homonym. (shrink)

The fairy tale The Three Princes of Serendip can be taken to be allegorical of not only chance discovery (serendipity) but of other aspects of scientific discovery as well. Just as Horace Walpole coined serendipity, so can the term bahramdipity be derived from the tale and defined as the cruel suppression of a serendipitous discovery. Suppressed, unpublished discoveries are designated nulltiples. Several examples are presented to make the case that bahramdipity is an existent aspect of scientific discovery. Other examples (...) of non-ideal scientific research and discovery are provided in order to contrast and clarify the meaning and use of bahramdipity. Additional allegories of scientific discovery are taken from the tale and a hope for the strengthening of scientific integrity is expressed. (shrink)

The controversy over vaccines has recently intensified in the wake of the global COVID-19 pandemic, with calls from politicians, health professionals, journalists, and citizens to take harsh measures against so-called “anti-vaxxers,” while accusing them of spreading “fake news” and as such, of endangering public health. However, the issue of suppression of vaccine dissenters has rarely been studied from the point of view of those who raise concerns about vaccine safety. The purpose of the present study was to examine the (...) subjective perceptions of professionals (physicians, nurses, researchers) involved with vaccines through practice and/or research and who take a critical view on vaccines, about what they perceive as the suppression of dissent in the field of vaccines, their response to it, and its potential implications on science and medicine. Respondents reported being subjected to a variety of censorship and suppression tactics, including the retraction of papers pointing to vaccine safety problems, negative publicity, difficulty in obtaining research funding, calls for dismissal, summonses to official hearings, suspension of medical licenses, and self-censorship. Respondents also reported on what has been termed a “backfire effect” – a counter-reaction that draws more attention to the opponents’ position. Suppression of dissent impairs scientific discourse and research practice while creating the false impression of scientific consensus. (shrink)

Executive control of attention refers to processes that detect and resolve conflict among competing thoughts and actions. Despite the high-level nature of this faculty, the role of awareness in executive control of attention is not well understood. In this study, we used interocular suppression to mask the flankers in an arrow flanker task, in which the flankers and the target arrow were presented simultaneously in order to elicit executive control of attention. Participants were unable to detect the flanker arrows (...) or to reliably identify their direction when masked. There was a typical conflict effect (prolonged reaction time and increased error rate under flanker-target incongruent condition compared to congruent condition) when the flanker arrows were unmasked, while the conflict effect was absent when the flanker arrows were masked with interocular suppression. These results suggest that blocking awareness of competing stimuli with interocular suppression prevents the involvement of executive control of attention. (shrink)

Brain mapping studies using dynamic imaging methods demonstrate areas regional cerebral blood flow (rCBF) decreases, as well as areas where increases, during performance of various experimental tasks. Task holds for both sets of cerebral blood flow changes (CBF), providing the opportunity to investigate areas that become and “activated” in the experimental condition relative to control state. Such data yield the intriguing observation that in areas in emotional processing, such as the amygdala, the posteromedial cortex, and the ventral anterior cingulate cortex, (...) although flow as expected during specific emotion-related tasks, flow decreases performance of some attentionally demanding, cognitive tasks. Conversely, in some of the areas that appear to subserve cognitive functions, as the dorsal anterior cingulate and the dorsolateral prefrontal cortices, increases while performing attentionally demanding cognitive tasks, but during some experimentally induced and pathological emotional Although the specific nature of such reciprocal patterns of regional remains unclear, they may reflect an important cross-modal interaction during mental operations. The possibility that neural activity is less in areas required in emotional processing during some higher cognitive processes holds implications for the mechanisms underlying interactions cognition and emotion. Furthermore, the possibility that neural in some cognitive-processing areas is suppressed during intense states suggests mechanisms by which extreme fear or severe may interfere with cognitive performance.

Moran conceives of conscious belief as a conscious activity, rather than awareness of a mental state. Once conscious belief is understood in this way, the notion of suppressed belief becomes problematic. In this paper, I draw on the work of Merleau-Ponty to sketch an account of suppressed belief. I suggest that suppressed beliefs should not be understood as attitudes towards propositions. Instead, they should be conceived as ways of perceiving and interacting with the world that are out of keeping with (...) how one repre-sents it as being. (shrink)

The attentional blink (AB) is an impairment of attention, which occurs when subjects have to report a target stimulus (T2) following a previous target (T1) with a short delay (up to 600 ms). Theories explaining the AB assume that processing of T2 is more vulnerable to decay or substitution, as long as attention is allocated to T1. Existing models of the AB, however, do not account for the fact that T2 detection accuracy reaches the minimum when T2 is presented after (...) about 300 ms and not immediately following T1. Therefore, a new model is suggested, which is based on chronometrical considerations together with recent neurophysiological findings concerning the relation between the P3 event-related potential and the AB, the interaction between P3 and gamma oscillations, and the significance of the early evoked gamma band response. We hypothesize that suppression of the early gamma response to T2, accompanying the P3 related to T1, causes the AB. (shrink)

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).

Stalinism is above all a regime, a personal power, an autocracy that repudiates democratic principles of social and political life, unifies culture, and embraces a repressive ideology formed around a mythological cult of a single person—the Master, and one value—Order. Here politics is replaced by intrigue, science—by servicing utilitarian and pragmatic ends, and philosophy—by the ideology of the ruling clique at the helm of a command-bureaucratic system, which also oppressed by the despotic will of the autocrat.

Illusions that produce perceptual suppression despite constant retinal input are used to manipulate visual consciousness. Here we report on a powerful variant of existing techniques, Continuous Flash Suppression. Distinct images flashed successively around 10 Hz into one eye reliably suppress an image presented to the other eye. Compared to binocular rivalry, the duration of perceptual suppression increased more than 10-fold. Using this tool we show that the strength of the negative afterimage of an adaptor was reduced by (...) half when it was perceptually suppressed by input from the other eye. The more likely the adaptor was completely suppressed, the larger the reduction of the afterimage intensity. Paradoxically, trial-to-trial visibility of the adaptor did not correlate with the degree of suppression. Our results imply that formation of afterimages involves neuronal structures that access input from both eyes, but that do not correspond directly to the neuronal correlates of perceptual awareness.

Participants were asked to carry out a series of simple tasks while following mental control instructions. In advance of each task, they either suppressed thoughts of their intention to perform the task, concentrated on such thoughts, or monitored their thoughts without trying to change them. Suppression resulted in reduced reports of intentionality as compared to monitoring, and as compared to concentration. There was a weak trend for suppression to enhance reported intentionality for a repetition of the action carried (...) out after suppression instructions had been discontinued. (shrink)

The Gospel of John reflects several layers of social memory and theological creativity concerning Jesus’s death. In the early material, there seems to be a suppressed awareness of Jesus’s fate and an unwillingness to unfold it in narrative form – something that recalls the hypothetical sayings gospel Q and the Gospel of Thomas. There is also a search for alternative, figurative ways to visualize the endpoint of Jesus’s earthly life. Eventually, the narrative memory of Jesus’s passion, as told in Mark (...) and Matthew, was adopted with some modifications. Among the modifications of the passion storyline is the narrativization of the image of Jesus as a Paschal Lamb, an image already known to Paul. The most remarkable innovation, however, was the figure of the “Beloved Disciple” as an eyewitness to Jesus’s passion and death. (shrink)

The 1945 discovery of ancient documents at Nag Hammadi in Egypt would have great significance for New Testament scholars.

The study focuses on the emotional-motivational experiences of Bedouin-Arab beginning teachers during the induction period, from the perspective of Self-Determination Theory. A phenomenological study was employed. Seventy-four teachers participated, 62 of whom completed open questionnaires, while semi-structured interviews were conducted with 12 other participants. The findings indicate that the beginning teachers reported experiences of coercion, exploitation, and gender-based discrimination. They also experienced a judgmental attitude, lack of assistance, and difficulties with students, and their sense of relatedness to the school is (...) impaired due to cultural factors. As a result, they expressed controlled motivation, a sense of burnout, stress, impaired well-being and disengagement in school. They also suppressed their students' autonomy. At the same time, the findings also show that when the teachers experience a sense of need satisfaction, they integrate well into the school. These findings indicate the necessity for establishing a need-supportive school environment for beginning teachers during their induction period. (shrink)

Erdelyi's two key tenets – that repression may be conscious (“suppression”) and that it is context-sensitive – resonate well with findings on unipolar depression. Drawing from this field, I argue that (1) “oppression,” namely, pressure from significant others to refrain from attending to certain mental contents, influences individuals' repression/suppression; and that, (2) individuals actively create the very contexts that facilitate their repression/suppression.

Tactile perception is often impaired during movement. The present study investigated whether such sensory suppression also occurs during back movements, and whether this would be modulated by attention. In two tactile detection experiments, participants simultaneously engaged in a movement task, in which they executed a back-bending movement, and a perceptual task, consisting of the detection of subtle tactile stimuli administered to their upper or lower back. The focus of participants’ attention was manipulated by raising the probability that one of (...) the back locations would be stimulated. The results revealed that tactile detection was suppressed during the execution of the back movements. Furthermore, the results of Experiment 2 revealed that when the stimulus was always presented to the attended location, tactile suppression was substantially reduced, suggesting that sensory suppression can be modulated by top-down attentional processes. The potential of this paradigm for studying tactile information processing in clinical populations is discussed. (shrink)

The results of the work show that the relatively small differences in declared, negative emotional states between people suffering and not suffering from cancer can be explained by the suppression of negative affect in the former.

The results confirmed that the connection of cancer and depression became significantly stronger while the self-esteem defensiveness and past (...) stress are statistically controlled. (shrink)

Today in education as well as in a society suppression and aggression reveal itself very actively. The word "suppression" in a modern society is used in many meanings; it includes all forms of physical, psychological and economic suppression. There is no system or mechanism to oppose it, to protect the education area of suppression and aggression, they are not outworked. Philosophy of education considers non-aggressive activity as a modern trend in Russian education, which developing non-aggressive relations (...) as a standard of social life will help the society to overcome the revealed suppression and aggression. Non-suppression is a principle, action, position. Non-suppression is an ideological, ethic and vital principle, which is based on recognition of all living, a man and his life, rejection of suppression as a way of relation of a man with the world, the nature and other people. There are many methods of non-suppressedactivity in education. First of all, it is a refusal of force; non-suppressed action as a collaboration, joint activity; non-suppressed action as a help; non-suppressed action as a reduction of aggressive value of opposite side.

Val Plumwood and Richard Sylvan argued from their joint paper The Semantics of First Degree Entailment and onward that the variable sharing property is but a mere consequence of a good entailment relation, indeed they viewed it as a mere negative test of adequacy of such a relation, the property itself being a rather philosophically barren concept. Such a relation is rather to be analyzed as a sufficiency relation free of any form of premise suppression. Suppression of premises, (...) therefore, gained center stage. Despite this, however, no serious attempt was ever made at analyzing the concept. This paper shows that their suggestions for how to understand it, either as the Anti-Suppression Principle or as the Joint Force Principle, turn out to yield properties strictly weaker than that of variable sharing. A suggestion for how to understand some of their use of the notion of suppression which clearly is not in line with these two mentioned principles is given, and their arguments to the effect that the Anderson and Belnap logics T, E and R are suppressive are shown to be both technically and philosophically wanting. Suppression-freedom, it is argued, cannot do the job Plumwood and Sylvan intended it to do. (shrink)

Introduction: Advantageous effects of biological motion detection, a low-perceptual mechanism that allows the rapid recognition and understanding of spatiotemporal characteristics of movement via salient kinematics information, can be amplified when combined with motor imagery, i.e., the mental simulation of motor acts. According to Jeannerod’s neurostimulation theory, asynchronous firing and reduction of mu and beta rhythm oscillations, referred to as suppression over the sensorimotor area, are sensitive to both MI and action observation of BM. Yet, not many studies investigated the (...) use of BM stimuli using combined AO-MI tasks. In this study, we assessed the neural response in the form of event-related synchronization and desynchronization patterns following the observation of point-light-walkers and concordant MI, as compared to MI alone.Methods: Twenty right-handed healthy participants accomplished the experimental task by observing BM stimuli and subsequently performing the same movement using kinesthetic MI. We recorded an electroencephalogram with 32 channels and performed time-frequency analysis on alpha and beta frequency bands during the MI task. A two-way repeated-measures ANOVA was performed to test statistical significance among conditions and electrodes of interest.Results: The results revealed significant ERD/S patterns in the alpha frequency band between conditions and electrode positions. Post hoc comparisons showed significant differences between condition 1 and condition 3 over the left primary motor cortex. For the beta band, a significantly less difference in ERD patterns was detected only between condition 3 and condition 4.Discussion: Our results confirmed that the observation of BM combined with MI elicits a neural suppression, although just in the case of jumping. This is in line with previous findings of AO and MI eliciting a neural suppression for simulated whole-body movements. In the last years, increasing evidence started to support the integration of AOMI training as an adjuvant neurorehabilitation tool in Parkinson’s disease.Conclusion: We concluded that using BM stimuli in AOMI training could be promising, as it promotes attention to kinematic features and imitative motor learning.

The ability of Glenberg's model to explain the development of complex symbolic abilities is questioned. Specifically, it is proposed that the concepts of clamping and suppression fall short of providing an explanation for higher symbolic processes such as autobiographical memory and language comprehension. A related concept, “holding in mind” (Olson 1993), is proposed as an alternative.

Although Glenberg 's theory benefits from the incorporation of a suppression concept, a more differentiated view of suppression would be even more effective. We propose such a concept, showing how it accounts for phenomena that Glenberg describes and also for phenomena that he ignores.
