Symbols enable people to organize and communicate about the world. However, the ways in which symbolic knowledge is learned and then represented in the mind are poorly understood. We present a formal analysis of symbolic learning—in particular, word learning—in terms of prediction and cue competition, and we consider two possible ways in which symbols might be learned: by learning to predict a label from the features of objects and events in the world, and by learning to predict features from a (...) label. This analysis predicts significant differences in symbolic learning depending on the sequencing of objects and labels. We report a computational simulation and two human experiments that confirm these differences, revealing the existence of Feature-Label-Ordering effects in learning. Discrimination learning is facilitated when objects predict labels, but not when labels predict objects. Our results and analysis suggest that the semantic categories people use to understand and communicate about the world can only be learned if labels are predicted from objects. We discuss the implications of this for our understanding of the nature of language and symbolic thought, and in particular, for theories of reference. (shrink)

A central goal of typological research is to characterize linguistic features in terms of both their functional role and their fit to social and cognitive systems. One long-standing puzzle concerns why certain languages employ grammatical gender. In an information theoretic analysis of German noun classification, Dye, Milin, Futrell, and Ramscar enumerated a number of important processing advantages gender confers. Yet this raises a further puzzle: If gender systems are so beneficial to processing, what does this mean for languages that make (...) do without them? Here, we compare the communicative function of gender marking in German to that of prenominal adjectives in English, finding that despite their differences, both systems act to efficiently smooth information over discourse, making nouns more equally predictable in context. We examine why evolutionary pressures may favor one system over another and discuss the implications for compositional accounts of meaning and Gricean principles of communication. (shrink)

In _Wild Blue Media_, Melody Jue destabilizes terrestrial-based ways of knowing and reorients our perception of the world by considering the ocean itself as a media environment—a place where the weight and opacity of seawater transforms how information is created, stored, transmitted, and perceived. By recentering media theory on and under the sea, Jue calls attention to the differences between perceptual environments and how we think within and through them as embodied observers. In doing so, she provides media studies (...) with alternatives to familiar theoretical frameworks, thereby challenging scholars to navigate unfamiliar oceanic conditions of orientation, materiality, and saturation. Jue not only examines media about the ocean—science fiction narratives, documentary films, ocean data visualizations, animal communication methods, and underwater art—but reexamines media _through_ the ocean, submerging media theory underwater to estrange it from terrestrial habits of perception while reframing our understanding of mediation, objectivity, and metaphor.

Increasing emphasis on genetic research means that growing numbers of human research projects in Australia will involve complex issues related to genetic privacy, familial information and genetic epidemiology. The Office of Population Health Genomics (Department of Health, Western Australia) hosted an interactive workshop to explore the ethical issues involved in the disclosure of genetic information, where researchers and members of human research ethics committees (HRECs) were asked to consider several case studies from an ethical perspective. Workshop participants used a variety (...) of approaches to examine the complex ethical issues encountered, but did not consistently refer to the values and principles outlined in the National Statement on Ethical Conduct in Human Research (NHMRC 2007) or apply rational ethical approaches. Overall, the data suggested that both researchers and HREC members may benefit from further education and support regarding the application of ethical frameworks to the issues encountered in genetic research.

In this paper, we examine Sextus Empiricus' treatise Against the geometers . We first set this treatise in the overall context of the sceptic's polemics against the liberal arts. After a discussion of Sextus' attitude to the quadrivium , we discuss the structure, the sources and the target of the Against the geometers . It appears that Euclid is not Sextus' source, and neither he, nor the professional geometers, seem to be Sextus' main targets. Of course, Sextus never really makes (...) clear his precise target, but his attacks are rather directed against geometry as a means of modelling the physical world, thus ruining the support geometry was intended to bring to the physical part of dogmatic philosophy.

Background: At a time when British nursing has been under scrutiny for an apparent lack of compassion in education and practice, this paper based offers a perspective on the notions of vocation and altruism in nursing. Objectives: To understand the vocational and altruistic motivations of nurses through the application of Pierre Bourdieu's concepts of ‘symbolic capital’, ‘field’ and ‘habitus’ through a long interview with nurse respondents. Research design: A reflexive qualitative study was undertaken using the long interview. A thematic analysis (...) of the data, using a qualitative data software package for analysis, was undertaken. The ideas of Pierre Bourdieu (Habitus, Capital and Field) were used to analyse and explain the content of community nurses' ‘talk’. Participants: Twelve Community Nurses working in a variety of local primary care settings volunteered to participate in the study. It was a self-selecting convenience sample of nurses responding to an invitation to be interviewed. Research context: A study in support of a doctoral thesis conducted within NHS primary care settings with registered nurses. Ethical considerations: The key considerations for this study were to be mindful of the possibility of emotional harm or distress being caused to the respondents during the retelling of their experiences. It was also essential to ensure that the locations or names of patients or staff (if discussed) were anonymised. Ethical approval was sought and granted by both the Local NHS Primary Care and the University Ethics committees before the study commenced. Findings: The nurse respondents had highly individual and at times contradictory views on their motivations to nurse including their views on vocation and altruism in nursing careers. Discussion: Bourdieu's ideas apply well to the nursing context and provided a useful theoretical framework to explore the social and cultural influences on nursing careers. Gender is important consideration in all aspects of nursing but class and educational experience is an important dimension in the stories nurses tell. Conclusion: The culturally determined experiences of these nurses in practice offer an authentic and realistic insight into the complex motives and predispositions of community nurses. This paper argues that nurse motivations whether vocational or altruistic, are better understood as culturally, rather than spiritually, driven. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Demea's Departure James Dye Although Demea's departure atthe end ofpart 11 is one ofthe dramatic highlights ofthe Dialogues,1 it has prompted little comment. That is a pity, since it is a striking departure from Hume's Ciceronian model in De natura deorum, and the motivation for the change is far from clear. What is clear is that to this point Philo and Demea have been informal allies. The conclusions ofPhilo's (...) sceptical arguments have dovetailed nicely with Demea's negative theology—an alliance, as it were, between reason aware of its own failure and faith which accepts the invincible mysteriousness of the divine. Both distrust reason's competence to attain knowledge of God. After Demea's departure, Cleanthes and Philo seem to embark on a more conciliatory relationship for which the preceding parts have so ill-prepared the reader that Philo's "reversal" or "confession" in part 12 has become a standard exegetical problem in the literature. If Demea must go to facilitate the reconciliation ofPhilo and Cleanthes, what motivates his exit now? The usual view takes the departure to be motivated by Demea's unhappiness with Philo's disquisition on evil. This is so vague as to be useless, especially since through most of part 10 Demea eagerly co-operates with Philoin describinglife in terms which make thereaUty of evil all the more compelling. If the dialogue is psychologically coherent, the subsequent conversation must introduce something else tomotivate Demea's departure. Whatis ofsuch significance that Hume chooses to punctuate it with the dramatic flourish of Demea's exit? It does have much to do, I think, with something Philo says, but not about "the problem ofevil" as that is usually construed. It has something to do with the problem of evil, but more with the implications of what Philo says than with his explicit claims. It will be necessary, however, to setthese factorsin theircontext; andfor that purpose,let's startwith part 9. Part 9 Many have located the beginnings ofa Demea-Philo rupture in part 9, not in Demea's perception ofPhilo, but in Philo's willingness to attack Demea. Specifically, Philo has commonly been taken to approve Cleanthes'criticisms ofDemea's argument and to add his own to them. The temptation to interpret Philo as endorsing Cleanthes' criticisms is particularly strong because those criticisms seem to echo Volume XVIII Number 2 467 JAMESDYE characteristically Humean positions. However, in this context, as criticisms ofDemea's argument, they are question-begging and, in fact, backfire on Cleanthes.2 Moreover, Philo does not say that he accepts Cleanthes'arguments. (Heisperhaps astonished that Cleanthes, inhis eagerness to attack any view which smacks of "old-fashioned" a priorism, can forcefully espouse views which undercut his own position.)3 His first remarks after Cleanthes' exceptionally spirited attack on Demea strongly resemble his remarks in part 2 following Demea's equally spirited initial objection (appealing to tradition and authority) to Cleanthes' argument.4 Both responses are playfully ironic, and we should no more presume that Philo endorses Cleanthes' argumentation in part 9 than we should assume him to endorse Demea's in part 2. Nor are Philo's own contributions to part 9 such as to give affront to Demea. He pointedly classifies the first ofthe two points he makes as "upon another topic" (D 191). Then he invokes as an example the fact that adding the digits ofany product of9 always yields either 9 or some lesser product of 9. The point of the example is that this fact, which initially seems marvellous and inexplicable, ceases to astonish one who understands mathematics sufficiently well to see that it is arithmetically necessary that the products of 9 have this property. Philo claims that it is probable that the similarly astonishing order of the universe may in like manner be determined by some intrinsic necessity in matter, which would seem equally unremarkable to us had we far more thorough knowledge of the nature of matter than we currently possess. The crux ofPhilo's argument is that ifa remarkable regularity or orderfound in certain numbers is numerically necessary, itrequires no further explanation; similarly, ifa remarkable regularity or order in nature is necessary, it does...

At the end of 2015‘s The Witch, isolated and beaten protagonist, Thomasin, ultimately rejects her puritanical upbringing to become a witch, accepting the invitation of the Devil (in the guise of the family’s goat Black Philip). This essay will discuss Thomasin’s sexual deliverance in terms of her turning away from the authoritarian ‘Law of the Father’ towards female liberation that comes in the form of the Witch. Thomasin transitions from girl to woman, but does not want to do so in (...) the restrictive Puritan fashion where patriarchy and oppression rules. She becomes a woman by embracing her sexuality in the figure of the witch and Black Philip as the figure of lust helping her become free. Western folklore posits the goat as a symbol of fertility, independence, and lust; Black Philip is a figure who represents a connection to wild desires. Therefore, Black Philip becomes not only a physical representation of the devil, but also a symbolic representation of Thomasin’s sexual desire. Drawing on theories of the monstrous-feminine (Creed, Kristeva, Arnold), the symbolism of folklore and Freud’s Electra complex, this work argues that, despite its message of feminine empowerment, The Witch cannot fully reject or escape patriarchal discourse.

Lying and deceit are instruments of power, used by social actors in the pursuit of their practices as they seek to maintain social order. All social actors, nurses included, have deceit and dishonesty within their repertoire of practice. Much of this is benign, well intentioned and a function of being sociable and necessary in the pursuit of social order in the healthcare environment. Lying and deceit from a sociological point of view, is a reflection of the different modes of domination (...) that exist within a social space. French philosopher Pierre Bourdieu theorized about the way that symbolic power works within social space. The social structures and the agency of individual actors moving within it are interrelated and interdependent. Bourdieu's ideas will be used to theorize about real clinical experiences where acts of deceit can be identified and a case example will be presented. Nurses are actors in the social space of clinical care, and their world is complex, challenging, and often fraught with the contradictory demands and choices that reflect and influence their behaviours. An exploration of lying and deceit in nursing as an instrument in the modes of domination that persist enables us to challenge some of the assumptions that are made about the motives that cause or tempt nurses to lie as well as to understand the way on which they are sometimes lied to, according to the acts of domination that exist in the field. Lying or acting dishonestly is a powerful act that is intent on retaining stability and social order and could be seen to be a justification of lying and deceit. However, we need to pause and consider, in whose interests are we striving to create social order? Is it in the end about the comfort of patients or for the comfort of professionals? (shrink)

Past research shows that the bilingual experience may enhance cognitive executive function. In this experiment, we evaluated cognitive control in bilinguals relative to monolinguals by using a dimensional overlap model to predict performance in a task composed of Stroop and Simon stimuli. A group of 24 Spanish monolinguals and 24 bilinguals with differing first languages and all having Spanish as a second language did a picture naming task and a task composed of Stroop and Simon stimuli, where the effect of (...) different overlap conditions between stimuli and responses were examined. The tasks were performed in Spanish for both groups and performance was indexed with behavioral and electrophysiological measures. We hypothesized that the bilinguals’ daily language practice in L2 reflected overlap conditions similar to the Simon task. Both naming a picture in L2 and the Simon task would involve conflict at the response level. L2 picture naming entails interference between two potential oral responses, to name in L2 vs. L1. Similarly, incongruent stimuli in the Simon task produce interference because the irrelevant dimension overlap with an incorrect response. In contrast, the manual Stroop task involves a different type of conflict between two overlapping stimulus dimensions. We predicted for these reasons a superior performance in Simon tasks over Stroop tasks for bilinguals, while monolinguals were expected to have a similar performance in both tasks. We also expected to see a correlation between the performance on the picture naming task and the Simon task in bilinguals. However, the behavioral results did not confirm these hypotheses. In fact, both groups had similar congruency effects as measured by reaction times and error rates, and there was no correlation between the picture naming and Simon task in bilinguals. Despite this, the electrophysiological data suggested a relationship between the picture naming task and the P300 congruency effect in bilinguals. Our findings provide insights into the neurocognitive bases of language and serve as a research avenue for language behaviors in bilinguals. (shrink)

To what extent do we pay attention to the text and images that cover our hospital walls and do we offer any critique either as professionals or service users? In the past we might have expected to see functional or helpful instructions about where to go (or not to go) and in more well‐endowed buildings, perhaps we would see some works of art, sculpture, stained glass even, with the intention to encourage, distract or even forewarn us. However, it is now (...) common in UK hospitals, for wall space to be used as a portal for a range of institutional political messages, that convey information about everything from its own values, behaviours to advertisements for products and services to requirements for rule following. Michel Foucault's ideas about Heterotopic space can help us to see that hospitals tend to fall (awkwardly) between being a public and personal health care space, and this is a possible explanation for the confused material culture and messages that are shared there. This paper draws on ethnographic methods to reflect on personal experience in order to offer a critique of the contemporary political discourse which has become 'literally' written onto our hospital walls.

In lieu of an abstract, here is a brief excerpt of the content:120 A WORD ON BEHALF OF DEMEA Little attention has been given to the a priori argument for God's existence espoused by Demea in Hume's Dialogues concerning Natural Religion. This circumstance is neither surprising nor unjustified. Given Hume's well-known theological sympathies, certainly no one would be tempted to regard Demea as Hume's spokesman. Demea's argument plays so small a role in the Dialogues as to suggest that Hume does (...) not take it at all seriously. He may present it only to establish that he is aware of alternative arguments for God's existence, but thinks them even less successful than the design argument and hence undeserving of extensive critique. Yet, if a philosopher criticizes an argument he deems unworthy of respect, he should still provide sound, not spurious, reasons for rejecting it. This is exactly what D. C. Stove has argued that Hume fails to do in Part IX of the Dialogues, assuming, as is generally done, that the speeches of Cleanthes and Philo present reasoning that Hume would personally endorse. Stove argues that most of the criticisms of Demea's argument are "extremely defective, and that they even include an inconsistency" (Stove, p. 300). This contention has been challenged by Donald Stahl, who has published a succinct point by point rebuttal of Stove's contentions.3 The Stove-Stahl controversy only deals with the reasoning presented in paragraphs 5, 6, 7, and 10 of Part IX because those are the contentions Stove attacks. He has "nothing to say against" the criticisms presented in paragraphs 8 and 9, which he assumes will be generally agreed to be 121 less important than the others (Stove, p. 308). He totally ignores the argument of paragraph 11. However, I am not convinced that the criticisms of these paragraphs are less important and I do have something to say against them. Consequently, instead of intervening directly on either side of the dispute between Professors Stove and Stahl, I shall attend principally to the argumentation of paragraphs 8, 9, and 11. I shall (1) summarize Demea's argument, (2) argue for the significance of the criticisms of paragraphs 8-9, (3) examine those criticisms, and (4) assess the role of Philo's concluding remarks in paragraphs 10-11. 1. Demea's Argument Early on Hume has Demea speak so obviously inconsistently as to make the reader wonder whether this character is supposed to think at all about the implications of the claims he espouses. At the beginning of Part II, he proclaims that God's existence is surely not at issue, since no one of common sense... ever entertained a serious doubt with regard to a truth so certain and self-evident." The nature of God is the only proper object of theological inquiry, and that is "altogether incomprehensible and unknown to us" (D 141)! Given such a radically apophatic position (Hume calls it "mystical"), it is hardly surprising that the sceptical Philo readily concurs, once he specifies that he takes 'God' to mean just "the original cause of this universe (whatever it be)" (D 142). But Demea immediately buttresses his alleged self-evident truth by appealing to the authority of Father Malebranche and the whole tradition of Christian theology, apparently oblivious to the impropriety of 122 supporting an indubitable truth by citing authorities (D 141-142). Further, scarcely more than a page later, after Cleanthes has sketched out the design argument, this same Demea is horrified that Cleanthes gives no abstract arguments or a priori proofs and calls for a "demonstration of the being of a God" (D 143). When, in Part IX, Demea himself undertakes to provide the "simple and sublime argument a priori" (D 188) he expected from Cleanthes, he characterizes the argument as "the common one," which suggests he is more engaged in paraphrasing authority than in thoughtfully arguing. The argument, in fact, as has been generally recognized, closely follows one given by Samuel Clarke in the Boyle Lectures of 1704. 5 Demea begins by assuming that "whatever exists must have a cause or reason of its existence," (D 188) since nothing can cause itself to exist. He then states a dilemma: in tracing the... (shrink)

Climate cuisine is about eating the future you want into being. In this article, I examine how seaweed recipes can be forms of climate fiction through the way that the reader is invited to participate in sustainable foodways. I examine several popularizations of seaweed aquaculture that imagine practices of eating and growing seaweeds. Their formal similarities center on participation: they include the direct address of the reader through the second person voice, and position themselves as instructional models. Bren Smith’s Eat (...) Like a Fish (Smith, Eat like a fish: My adventures as a fisherman turned restorative ocean farmer, Penguin, 2019) interpellates the reader as eater, invited to cultivate eating habits that, on a societal scale, would produce a more materially sustainable relation with the planet. The vignette “Ghost Bar,” which appears in Holly Jean Buck’s After Geoengineering: Climate Tragedy, Repair, and Restoration (Buck, After geoengineering: Climate tragedy, repair, and restoration, Verso, 2019), sensorily emplaces the reader in a future seaweed farm as a window into the kinds of livelihoods and forms of work that could be part of mitigating global warming. I trace the similarities between Smith's recipes and Buck’s interpellation of a reader, both of which use the second-person mode addressing an unmarked “you,” inviting this “you” to imagine and actualize the future dish or future scenario they sketch. While these texts have their own limitations at the level of the social imagination, such popularizations of seaweed aquaculture model an important way of understanding the intimacies of climate fiction and recipes. Recipes not only popularize the sustainable eating of seaweeds, but actively constitute a form of climate fiction through their intention to actualize more seaweedy futures. (shrink)

This study investigates the procedural learning, retention, and reactivation of temporal sensorimotor sequences in children with and without developmental coordination disorder. Twenty typically-developing children and 12 children with DCD took part in this study. The children were required to tap on a keyboard, synchronizing with auditory or visual stimuli presented as an isochronous temporal sequence, and practice non-isochronous temporal sequences to memorize them. Immediate and delayed retention of the audio-motor and visuo-motor non-isochronous sequences were tested by removing auditory or visual (...) stimuli immediately after practice and after a delay of 2 h. A reactivation test involved reintroducing the auditory and visual stimuli after the delayed recall. Data were computed via circular analyses to obtain asynchrony, the stability of synchronization and errors. Firstly, an overall deficit in synchronization with both auditory and visual isochronous stimuli was observed in DCD children compared to TD children. During practice, further improvements were found for the audio-motor non-isochronous sequence compared to the visuo-motor non-isochronous sequence in both TD children and children with DCD. However, a drastic increase in errors occurred in children with DCD during immediate retention as soon as the auditory stimuli were removed. Reintroducing auditory stimuli decreased errors in the audio-motor sequence for children with DCD. Such changes were not seen for the visuo-motor non-isochronous sequence, which was equally learned, retained and reactivated in DCD and TD children. All these results suggest that TD children benefit from both auditory and visual stimuli to memorize the sequence, whereas children with DCD seem to present a deficit in integrating an audio-motor sequence in their memory. The immediate effect of reactivation suggests a specific dependency on auditory information in DCD. Contrary to the audio-motor sequence, the visuo-motor sequence was both learned and retained in children with DCD. This suggests that visual stimuli could be the best information for memorizing a temporal sequence in DCD. All these results are discussed in terms of a specific audio-motor coupling deficit in DCD.

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)
