The remediation of executive function in patients with schizophrenia is important in rehabilitation because these skills affect the patient's capacity to function in the community. There is evidence that instructional techniques can improve deficits in the Wisconsin Card Sorting Test (WCST) in some schizophrenia patients. We used a standard test/training phase/standard test format of the WCST to classify 36 schizophrenia patients as high-achievers, learners or non-retainers. All healthy controls performed as high-achievers. An event-related fMRI design assessed neural activation patterns during post-training WCST performance. Patients showed a linear trend between set-shifting related activation in the anterior cingulate cortex and learning potential, i.e. increased activation in high-achievers, a trend for increased activation in learners, and no activation in non-retainers compared to controls. In addition, activation in the temporoparietal cortex was highest in patients classified as learners, whereas in non-retainers activation was increased in the inferior frontal gyrus compared to controls and high-achieving patients. These results emphasize the relevance of the ACC's neural integrity in learning set-shifting strategies for patients with schizophrenia. Also, our results support the hypothesis that compensatory neural activation in patients with schizophrenia helps them to catch up with healthy controls on cognitive tasks. 相似文献

People are often mistaken when estimating and predicting quantities, and sometimes they report values that they know are false: they lie. There exists, however, little research devoted to how such deviations are being perceived. In four vignette studies, participants were asked to rate the accuracy of inaccurate statements about quantities (prices, numbers and amounts). The results indicate that overstatements are generally judged to be more inaccurate than understatements of the same magnitude; self-favorable (optimistic) statements are considered more inaccurate than unfavorable (pessimistic) statements, and false reports (lies) are perceived to be more inaccurate than equally mistaken estimates. Lies about the future did not differ from lies about the past, but own lies were perceived as larger than the same lies attributed to another person. It is suggested that estimates are judged according to how close they come to the true values (close estimates are more correct than estimates that are less close), whereas lies are judged as deviant from truth, with less importance attached to the magnitude of the deviation. 相似文献

In these comments I briefly discuss three aspects of the empiricist account of the epistemic role of experience that Anil
Gupta develops in his Empiricism and Experience. First, I discuss the motivations Gupta offers for the claim that the given
in experience should be regarded as reliable. Second, I discuss two different ways of conceiving of the epistemic significance
of the phenomenology of experience. And third, I discuss whether Gupta’s account is able to deliver the anti-skeptical results
he intends it to. I close by suggesting that, once fully fleshed out, Gupta’s account is best understood in terms of the fusion
of certain core ideas within both the empiricist and the rationalist traditions. 相似文献

The aim of the study was to train and test support vector machines (SVM) and self-organizing maps (SOM) to correctly classify gait patterns before, during and after complete leg exhaustion by isokinetic leg exercises. Ground reaction forces were derived for 18 gait cycles on 9 adult participants. Immediately before the trials 7–12, participants were required to completely exhaust their calves with the aid of additional weights (44.4 ± 8.8 kg). Data were analyzed using: (a) the time courses directly and (b) only the deviations from each individual’s calculated average gait pattern. On an inter-individual level the person recognition of the gait patterns was 100% realizable. Fatigue recognition was also highly probable at 98.1%. Additionally, applied SOMs allowed an alternative visualization of the development of fatigue in the gait patterns over the progressive fatiguing exercise regimen. 相似文献

Young adults with a family history of mental illness may be vulnerable to develop mental health conditions based on genetic and environmental features. This study aimed to explore factors associated with the use of mental health websites for young adults aged 18–30 years who reported a family history of mental illness. Young adults (n = 469) who reported a family history of mental illness completed an online survey regarding their use of mental health websites, demographic questionnaires and the Depression, Anxiety and Stress Scales. In total, 194 (41%) participants reported using mental health websites, with the majority using these for their own mental well-being (n = 156; 33%). Having a previous history of a mental health condition was associated with mental health website use, along with having a prior history of drug use and having more than one family member diagnosed with a mental illness. 相似文献

This paper documents the multifaceted nature of pride in consumer behavior. Drawing on recent psychological research on pride, we provide evidence for two separate facets of pride in consumption. In a series of studies, we propose a model wherein luxury brand consumption and pride are systematically interrelated. Whereas authentic (but not hubristic) pride leads to a heightened desire for luxury brands, hubristic (but not authentic) pride is the outcome of these purchases, and is the form of pride signaled to observers by these purchases. Further, we show that these effects are generally exacerbated for those low in narcissism. These findings shed new light on why consumers purchase luxury brands, highlighting a paradox: these purchases may be sought out of heightened feelings of accomplishment (and not arrogance), but they instead signal arrogance to others (rather than accomplishment). 相似文献

The Probability of Guilt in Criminal Cases: Are People Aware of Being ‘Beyond Reasonable Doubt’? 下载免费PDF全文
Svein Magnussen Dag Erik Eilertsen Karl Halvor Teigen Ellen Wessel 《Applied cognitive psychology》2014,28(2):196-203
Data from a series of studies presenting video recorded witness statements to laypersons and legal professionals were examined to trace the relationship between judged probability of guilt and the willingness to vote guilty or not guilty in hypothetical trials, in the absence of specific jury instructions. The results show that a majority of jury‐eligible young and elderly participants, and police officers, were willing to convict a defendant when the judged probability of guilt exceeded .6. This is considerably below the legally accepted standard of ‘beyond reasonable doubt’, which usually is equated with a very high, around .9 perceived certainty. When jury deliberations were allowed, the threshold for conviction rose, approaching the standard evinced by trial judges under the same conditions. The results suggest that people prefer to vote for guilt according to a balance of probabilities principle, considering only the individual case, and disregarding the implied frequencies of false convictions.
