Some aspects of executive function are thought to be dysfunctional in psychopathic individuals. We administered a small battery of neuropsychological tests (spatial alternation task, object alternation task, and Porteus Maze) to two samples of college students and obtained a measure of psychopathy via a self-report questionnaire. Psychopathic traits were related to the tests of object alternation and Porteus Maze but not to the spatial alternation task. Our results support the hypothesis of orbitofrontal cortex (OFC) dysfunction with sparing of dorsolateral prefrontal cortex (DLPFC) in psychopathy and provide a downward extension of this theory to sub-clinical levels of psychopathy. 相似文献

When adults are asked to recall their earliest autobiographical memories most can recall nothing about their infancy and early childhood, a phenomenon commonly referred to as childhood amnesia. There is general consensus regarding the existence of childhood amnesia, but there remains considerable debate over its boundary. Most researchers have argued that the boundary of childhood amnesia occurs between the ages of 3 and 4 years, but in 1993 Usher and Neisser published a highly influential paper, which has subsequently been used to argue that the boundary may be as low as 2 years. In the present experiment we examined how changes in scoring criteria influence our estimates of the age of adults’ earliest memories. We conclude that some coding criteria are more valid than others and that the best estimates of childhood amnesia will include measures of free recall in addition to the specific questions that have dominated prior research in this area. 相似文献

This article seeks to document the characteristics and themes of later trauma recovery using a grounded theory analysis of interviews with trauma survivors enrolled in outpatient treatment. Little research exists that speaks to patients’ own accounts of the process of trauma recovery. Such accounts might elucidate how psychotherapy helps survivors make and remake meaning of their lives, their experience of traumatic events, and the resources they might call on in psychotherapy to secure recovery. This study examined narrative material gathered in a series of interviews with trauma survivors (n?=?14) who had been in treatment for an average of 8 months and could be described as in a later phase of the recovery process. Two significant themes emerged from the analysis: (a) greater coherence to the trauma narrative, and (b) the emergence of a more reflective and observational stance with respect to one's history. Implications for trauma-informed therapy are discussed. 相似文献

In this I essay I analyse four sermons delivered at Shan festivals that celebrates the end of the Rains Retreat (Waa). I first argue that sermons in general are important sources of information about lived Buddhism. I next provide background information necessary to understand the sermon events and the sermons. In conclusion, I compare the sermons and discuss what laypeople can learn from sermons and what we, as academics, can learn from them. 相似文献

We conducted two studies to investigate if and how: (1) the rate of skill acquisition was related to motor performance at retention of a serial RT task (Study 1); and (2) whether rate of skill acquisition and baseline performance could be used to design schedules of practice related to contextual interference (CI) to enhance motor learning (Study 2). In Study 1, a slower rate of skill acquisition of repeating sequences in practice was related to faster response times at retention. Based on performance in Study 1, three levels of individualized CI were created for Study 2. Compared to low and moderate levels of CI, the higher CI practice condition led to faster response times in retention. We conclude that an individualized ‘challenge point’, which generates high CI enhances motor learning by optimizing challenge. 相似文献

Bayesian rationality is the paradigm of rational behavior in neoclassical economics. An economic agent is deemed rational when she maximizes her subjective expected utility and consistently revises her beliefs according to Bayes's rule. The paper raises the question of how, when and why this characterization of rationality came to be endorsed by mainstream economists. Though no definitive answer is provided, it is argued that the question is of great historiographic importance. The story begins with Abraham Wald's behaviorist approach to statistics and culminates with Leonard J. Savage's elaboration of subjective expected utility theory in his 1954 classic The Foundations of Statistics. The latter's acknowledged fiasco to achieve a reinterpretation of traditional inference techniques along subjectivist and behaviorist lines raises the puzzle of how a failed project in statistics could turn into such a big success in economics. Possible answers call into play the emphasis on consistency requirements in neoclassical theory and the impact of the postwar transformation of U.S. business schools. 相似文献

Emerging evidence suggests that variants of specific genes may influence some youths to seek out or associate with antisocial peers. Using genotypic data (N = 1,816) from the National Longitudinal Study of Adolescent Health (J. R. Udry, 1998, 2003), the authors tested this possibility. They found that the 10R allele of the dopamine transporter (DAT1) gene was associated with self-reported delinquent peer affiliation for male adolescents from high-risk environments (β range = .13-.14) despite controlling for delinquent involvement, self-control, and drug and alcohol use. The authors discuss the importance of using a biosocial framework to examine issues related to adolescent development. 相似文献

The reliability and validity of the Parent's Observations of Social Interactions (POSI), a new, seven‐item screening instrument for autism spectrum disorders (ASD), is examined in two substudies. In Study 1, parents of 217 children (18–48 months) evaluated at a developmental clinic completed intake questionnaires that included the POSI and the Modified Checklist for Autism in Toddlers (M‐CHAT) checklist. POSI and M‐CHAT scores were compared to clinical evaluation results to assess reliability and validity. In Study 2, parents of 232 children (16–36 months) from both primary care and subspecialty settings completed the POSI, the M‐CHAT, and a report of their child's diagnoses. POSI and M‐CHAT scores were compared to reported diagnoses to assess reliability and validity. In both studies, the POSI demonstrated adequate internal reliability (Cronbach α = 0.83 and 0.86, respectively). In Study 1, POSI sensitivity (89%) was higher than that for the M‐CHAT (71%; p < .05); specificities were not significantly different (POSI: 54%, M‐CHAT: 62%). In Study 2, sensitivity (83%) compared favorably to that for the M‐CHAT (50%), although specificity was lower (75 vs. 84%). Despite its brevity, the POSI demonstrated good internal reliability and comparable sensitivity/specificity to the M‐CHAT checklist in two independent populations. If results are reproduced in larger, more diverse samples, the POSI may provide an efficient method for ASD screening in young children. 相似文献

The current study seeks to advance the faceted multidimensional scaling (termed FMDS) procedure used in much of the investigative psychology research. To this end, recent research on street robbery by Goodwill and colleagues will be utilised to illustrate the effectiveness of a facet scale method for offender profiling. Four FMDS themes of street robbery (Con, Blitz, Confrontation and Snatch) were revealed by the crossing of two underlying axial facets: the offenders' level of violence and interaction with the victim. The facet scale method, utilising offenders' axial facet scores, was compared to previous count, proportional and centroid classification methods in the prediction of offender criminal histories. Utilising logistic regression and receiver operating characteristic analyses, the axial facet scale method was found to significantly outperform the qualitatively based dominant theme classification methods that typically employ angular and radial facets for FMDS interpretation. Implications for the use of axial facet scales within FMDS analysis for offender profiling research are discussed. Copyright © 2012 John Wiley & Sons, Ltd. 相似文献

AbstractPositive psychology has made significant advances in our understanding of well-being, yet agreement about the definition and nature of well-being remains elusive. This study explores the experience of well-being from a bottom-up, naturalistic point of view and compares these inductive notions with existing a priori theories. Using a qualitative-focused case study methodology, this paper explores how everyday people describe well-being in the context of job loss among a sample of 20 workers from the Ottawa, Canada technology sector. Findings support integrated conceptualizations of hedonia and eudaimonia while also potentially identifying new notions of well-being. Identified themes include (a) life evaluation, (b) transitory experiencing, (c) growth and grounding, (d) environmental mastery/stability, (e) mental ill-being/ill-health, and (f) motivational mindsets/conditions. This study shows well-being to be a rich, pluralistic construct which includes the non-dualistic notions of both subjectivity and objectivity as well as encompassing notions related to the ‘what’ and ‘how’ of well-being. 相似文献
