Connectionist models offer concretemechanisms for cognitive processes. When these modelsmimic the performance of human subjects theycan offer insights into the computationswhich might underlie human cognition. We illustratethis with the performance of a recurrentconnectionist network which produces the meaningof words in response to their spellingpattern. It mimics a paradoxical pattern oferrors produced by people trying to read degradedwords. The reason why the network produces thesurprising error pattern lies in the nature ofthe attractors which it develops as it learns tomap spelling patterns to semantics. The keyrole of attractor structure in the successfulsimulation suggests that the normal adult semanticreading route may involve attractor dynamics, andthus the paradoxical error pattern isexplained. 相似文献

Moral intensity is a construct that relates to issues in terms of their perceived moral significance. Individuals' perceptions of moral intensity should impact their recognition of issues as posing moral dilemmas and should also affect ethical judgments and behavioral intentions regarding issues. This study examined the relationship between 4 dimensions of moral intensity and the ethical decision-making process. Two work-related actions were presented to respondents, who then completed measures of the 4 dimensions of moral intensity, whether the actions posed an ethical issue, ethical judgments regarding the actions, and the likelihood that they would engage in the actions. Results indicate that moral intensity dimensions were associated with individuals' ethical decisions. Social consensus and seriousness of consequences were particularly important influences on the ethical decision-making process. 相似文献

This paper contrasts two approaches to agentive self-awareness: a high-level, narrative-based account, and a low-level comparator-based
account. We argue that an agent’s narrative self-conception has a role to play in explaining their agentive judgments, but
that agentive experiences are explained by low-level comparator mechanisms that are grounded in the very machinery responsible
for action-production. 相似文献

Effects of two meditation and mindfulness-based spiritual interventions were examined in college undergraduates (N=44). Compared to a control group, both interventions decreased negative religious coping (d=−0.80, p<.01) and images of God as mainly controlling (d=−.73, p<.01). One intervention provided more training in tools for learning from community and tradition-based spiritual exemplars.
It produced gains in famous or traditional spiritual exemplars’ perceived influence (d=+.81, p<.05) and availability (d=+.66, p<.10), in self-efficacy for learning from spiritual exemplars (d=+.92, p<.05), and in nonmaterialistic aspirations (d=+0.65, p<.05). 相似文献

Live identification procedures in England and Wales have been replaced by use of video, which provides a sequential presentation of facial images. Sequential presentation of photographs provides some protection to innocent suspects from mistaken identification when used with strict instructions designed to prevent relative judgements (Lindsay, Lea, & Fulford, 1991 ). However, the current procedure in England and Wales is incompatible with these strict instructions. The reported research investigated whether strict instructions would enhance the reliability of identification from video. The effect of using moving rather than still video clips was also investigated. Participants witnessed a live staged incident, and attempted to identify the culprit later from police video lineups, which were run double blind. Strict instructions produced a significantly lower rate of correct identifications in culprit present lineups, but did not significantly reduce the rate of mistaken identification in culprit absent lineups. Moving images yielded fewer mistaken identifications in culprit absent lineups. Copyright © 2006 John Wiley & Sons, Ltd. 相似文献

Research has demonstrated that repeated retrieval enhances memory for practised verbal information, but undermines correct recall of unpractised related verbal information, a phenomenon known as retrieval-induced forgetting (RIF). This paper addresses the question of what happens with memory for unrehearsed aspects of an emotional picture when retrieval of other aspects of that picture is practised. In two experiments we investigated whether repeated retrieval of certain details of negative emotional slides undermines recall of unrehearsed details of such slides. In Experiment 1 retrieval of peripheral details was practised. The results demonstrated that recall for peripheral details was enhanced. However, correct recall of unpractised central details remained unaffected. Furthermore, retrieval practice did not alter the number of commission errors. Experiment 2 revealed that repeated retrieval of central details enhanced memory for these details. Although more commission errors were produced, again correct recall was not impaired for the unrehearsed central and peripheral details. This failure to find retrieval-induced forgetting effects for complex visual material is at odds with the RIF literature, and potential reasons for this are discussed. The data also extend previous studies in demonstrating that extensive retrieval can increase the number of commission errors. 相似文献

This research paper presents an examination of the journey to and from crime for auto‐theft offenders in the UK. For 852 offences, ‘wheel’ distances are calculated for triangles formed by offenders' home location, theft location, and vehicle disposal location. The study demonstrates typical isosceles mobility triangles; distances travelled to and from home locations are roughly equal, whereas distances between theft and disposal points were shorter. Distances travelled by offenders under 17 years old and offences involving drug and drink were shown to be shorter than comparison groups. Prolific offenders tend to travel further, although there is significant variation in this subgroup. Explanations and implications are discussed. Copyright © 2008 John Wiley & Sons, Ltd. 相似文献

The emergence of modern humans with their extraordinary cognitive capacities is ascribed to a novel type of cognitive computational process (sustained non-routine multi-level operations) required for abstract projectuality, held to be the common denominator of the cognitive capacities specific to modern humans. A brain operation (latching) that allows this novel computational process is proposed as well as a physics-inspired mechanism that could explain its rather recent emergence without invoking unlikely genetic or structural changes. 相似文献

Two experiments contrasted interactions between group leaders with interactions between individuals in a mixed-motive setting. Consistent with the idea that being accountable to the in-group implies normative pressure to benefit the in-group, Experiment 1 found that accountable leaders were more competitive than individuals. Consistent with the idea that being unaccountable to the in-group implies normative pressure to be cooperative and that high guilt proneness provides motivation to be moral, Experiment 2 found that when guilt proneness was high, unaccountable leaders were less competitive than accountable leaders and did not differ significantly from individuals. In other words, the robust interindividual-intergroup discontinuity effect was eliminated when groups had unaccountable leaders who were high in guilt proneness. 相似文献

OBJECTIVE: To determine the relationship between joint variation in 2 dopaminergic genes and the likelihood of nonsmoking following treatment with bupropion sustained release (SR). DESIGN: Three hundred twenty-three participants in a bupropion SR smoking cessation effectiveness trial with 12-month follow-up were genotyped for variants of dopamine receptor gene DRD2 and dopamine transporter SLC6A3. MAIN OUTCOME MEASURES: Self-reported 7-day point prevalence of nonsmoking. RESULTS: Neither genotype alone was associated with 7-day point-prevalent nonsmoking at the 12-month follow-up. However, in the presence of the DRD2 A1 allele, SLC6A3 status was significantly associated with the likelihood of nonsmoking at the 12-month follow-up (individuals with DRD2 A1+ and SLC6A3 9- were more likely to be smoking). In the absence of the DRD2 A1 allele, the association between SLC6A3 status and nonsmoking was nonsignificant. CONCLUSION: Although these results are suggestive, a more compelling test is needed of the hypothesis that dopaminergic gene interaction underlies, in part, the likelihood of smoking following treatment with bupropion SR. Most likely this will come from larger studies involving prospective randomization to treatment based on genotype. 相似文献
