Interest in cognitive research in pigs is increasing, but little is known about the impact of environmental conditions on pigs’ cognitive capabilities. The present study investigated the effect of environmental enrichment on cognitive performance of pigs in a holeboard spatial task, in which they had to discriminate four baited buckets out of 16. Pigs (n = 32) were either housed in stimulus-poor, barren pens, or in larger pens enriched with rooting substrates. Pigs were subjected to 30 holeboard trials. Both working memory (WM), that is, the ratio (baited visits/total number of (re)visits to baited buckets), and reference memory (RM), that is, the ratio ((re)visits to baited buckets/total number of visits to all buckets), improved over trials. WM scores were higher in pigs from enriched pens than in pigs from barren pens. Housing did not affect RM scores. Personality type of the pigs, as assessed early in life using a backtest, did not affect WM or RM. In conclusion, housing conditions of pigs did not affect reference memory, but environmental enrichment improved working memory of pigs in a spatial discrimination task. Based on the findings of this study, we suggest that cognitive functioning of pigs may be impaired under commonly used housing conditions. 相似文献

What has the dispositional analysis of properties and laws (e.g. Molnar, Powers, Oxford University Press, Oxford, 2003; Mumford, Laws in nature, Routledge London, 2004; Bird, Nature’s metaphysics, Clarendon Press, Oxford, 2007) to offer to the scientific understanding of physical properties?—The article provides an answer to this question for the case of spacetime points and their metrical properties in General Relativity. The analysis shows that metrical properties are not ‘powers’, i.e. they cannot be understood as producing the effects of spacetime on matter with metaphysical necessity. Instead they possess categorical characteristics which, in connection with specific laws, explain those effects. Thus, the properties of spacetime do not favor the metaphysics of powers with respect to properties and laws. 相似文献

Metonymies are exemplary models for complex semantic association processes at the sentence level. We investigated processing of metonymies using event-related functional magnetic resonance imaging (fMRI).During an 1.5 Tesla fMRI scan, 14 healthy subjects (12 female) read 124 short German sentences with either literal (like “Africa is arid”), metonymic (“Africa is hungry”), or nonsense (“Africa is woollen”) content. Sentences were constructed so that they obey certain grammatical, semantic, and plausibility conditions and were matched for word frequency, semantic association, length and syntactic structure. We concentrated on metonymies that were not yet fossilised; we also examined a wide variety of metonymic readings.Reading metonymies relative to literal sentences revealed signal changes in a predominantly left-lateralised fronto-temporal network with maxima in the left and right inferior frontal as well as left middle temporal gyri. Left inferior frontal activation may reflect both inference processes and access to world knowledge during metonymy resolution. 相似文献

Temporomandibular disorders (TMD) are a painful condition present in 3% of the population. The aim of the present study was to develop a biofeedback-based cognitive-behavioral treatment for chronic TMD (BFB-KVT) and to evaluate its effectiveness compared to dental treatment. A total of 26 patients suffering from chronic TMD were randomly assigned to either BFB-KVT (n=15) or occlusal splint treatment (n=11). Preliminary data showed that both treatments reduced pain intensity and jaw disability. Greater improvement of pain-related disability was found for BFB-KVT, and its acceptance by the patients was higher. The proposed protocol appears to be an effective treatment for chronic TMD. The evaluation in a larger sample and of long-term efficacy will follow. 相似文献

‘Wearing a headscarf is my personal choice.’ With this statement, Jasmina, a 16-year-old Moroccan daughter of immigrants, characterizes her position in Dutch society. The headscarf indicates her religion and, indirectly, her origins. In wearing it, she indicates to others that she is a Muslim and a member of the umma, the Muslim community. Her comment that this is her personal choice is indicative of the process of individualization that is taking place in western Dutch society, where people are increasingly faced with having to make their own decisions. The process of individualization implies detachment from collective relationships such as religious communities, but the choice to wear a headscarf appears to indicate a choice made in the opposite direction. In this article the author discusses this paradox from an anthropological perspective. 相似文献

The recent discovery of individuals with superior face processing ability has sparked considerable interest amongst cognitive scientists and practitioners alike. These ‘Super‐recognizers’ (SRs) offer clues to the underlying processes responsible for high levels of face processing ability. It has been claimed that they can help make societies safer and fairer by improving accuracy of facial identity processing in real‐world tasks, for example when identifying suspects from Closed Circuit Television or performing security‐critical identity verification tasks. Here, we argue that the current understanding of superior face processing does not justify widespread interest in SR deployment: There are relatively few studies of SRs and no evidence that high accuracy on laboratory‐based tests translates directly to operational deployment. Using simulated data, we show that modest accuracy benefits can be expected from deploying SRs on the basis of ideally calibrated laboratory tests. Attaining more substantial benefits will require greater levels of communication and collaboration between psychologists and practitioners. We propose that translational and reverse‐translational approaches to knowledge development are critical to advance current understanding and to enable optimal deployment of SRs in society. Finally, we outline knowledge gaps that this approach can help address. 相似文献

Ethical issues are an inevitable part of genetic counseling practice. Prior research identified 16 domains of ethical and
professional challenges encountered by practitioners in the United States. In order to further validate these domains, the
present study surveyed Australian genetic counselors. Sixty-three respondents rated the frequency with which they encountered
each domain, and 39 individuals also provided personal anecdotes detailing their most challenging ethical and professional
dilemmas. Every domain reportedly was experienced by the Australian sample. However, there were some differences between Australian
respondents and U.S. genetic counselors in frequencies of domain occurrence, and in strategies recommended for resolving them.
Several anecdotes illustrate challenging situations due to Australia’s geography, universal healthcare system, and the genetic
counseling profession’s evolution in that country. The results generally validate domains identified for U.S. genetic counselors.
They further suggest that certain ethical issues may manifest in ways unique to a given country, and therefore they must be
addressed in a culturally-appropriate manner. 相似文献

The aim of this paper is to show that the widespread opinion, according to which functional role theories of representation
fail to account for content explanations of human and animal behaviour, cannot be confirmed with respect to each type of functional
role theory. Functional resemblance theories (as referred to by O’Brien and Opie in Representation in mind, Elsevier, 2004) allow for content explanations of successfully performed cognitive abilities as much as for explanations of systematic errors
resulting from misrepresentation. How functional roles do their explanatory work in actual scientific research examples is
shown by a detailed exploration of model assumptions about homing performances based on path integration mechanisms in humans
and animals.

Toward a theory of visual consciousness. 总被引:3,自引:0,他引:3
The visual brain consists of several parallel, functionally specialized processing systems, each having several stages (nodes) which terminate their tasks at different times; consequently, simultaneously presented attributes are perceived at the same time if processed at the same node and at different times if processed by different nodes. Clinical evidence shows that these processing systems can act fairly autonomously. Damage restricted to one system compromises specifically the perception of the attribute that that system is specialized for; damage to a given node of a processing system that leaves earlier nodes intact results in a degraded perceptual capacity for the relevant attribute, which is directly related to the physiological capacities of the cells left intact by the damage. By contrast, a system that is spared when all others are damaged can function more or less normally. Moreover, internally created visual percepts-illusions, afterimages, imagery, and hallucinations-activate specifically the nodes specialized for the attribute perceived. Finally, anatomical evidence shows that there is no final integrator station in the brain, one which receives input from all visual areas; instead, each node has multiple outputs and no node is recipient only. Taken together, the above evidence leads us to propose that each node of a processing-perceptual system creates its own microconsciousness. We propose that, if any binding occurs to give us our integrated image of the visual world, it must be a binding between microconsciousnesses generated at different nodes. Since any two microconsciousnesses generated at any two nodes can be bound together, perceptual integration is not hierarchical, but parallel and postconscious. By contrast, the neural machinery conferring properties on those cells whose activity has a conscious correlate is hierarchical, and we refer to it as generative binding, to distinguish it from the binding that might occur between the microconsciousnesses. 相似文献

Principled moral sentiment and the flexibility of moral judgment and decision making 总被引:1,自引:0,他引:1
Bartels DM 《Cognition》2008,108(2):381-417
Three studies test eight hypotheses about (1) how judgment differs between people who ascribe greater vs. less moral relevance to choices, (2) how moral judgment is subject to task constraints that shift evaluative focus (to moral rules vs. to consequences), and (3) how differences in the propensity to rely on intuitive reactions affect judgment. In Study 1, judgments were affected by rated agreement with moral rules proscribing harm, whether the dilemma under consideration made moral rules versus consequences of choice salient, and by thinking styles (intuitive vs. deliberative). In Studies 2 and 3, participants evaluated policy decisions to knowingly do harm to a resource to mitigate greater harm or to merely allow the greater harm to happen. When evaluated in isolation, approval for decisions to harm was affected by endorsement of moral rules and by thinking style. When both choices were evaluated simultaneously, total harm -- but not the do/allow distinction -- influenced rated approval. These studies suggest that moral rules play an important, but context-sensitive role in moral cognition, and offer an account of when emotional reactions to perceived moral violations receive less weight than consideration of costs and benefits in moral judgment and decision making. 相似文献
