Covert face recognition in neurologically intact participants 总被引:1,自引:0,他引:1
Prosopagnosic patients may maintain some ability to recognize familiar faces, although they remain unaware of this ability.
This phenomenon – called covert face recognition – was investigated in neurologically intact participants, using priming techniques.
Participants were quicker to indicate that a target-name was familiar when the preceding prime-face belonged to the same person
compared with an unrelated familiar person. This was observed both when prime-faces could be recognized overtly and when they
were presented too briefly to be recognized overtly (Exps. 1 and 2). Thus, covert face recognition was observed in neurologically
intact participants. In Exp. 3, participants were quicker to recognize a familiar face when that person's face had been seen
previously, but only when it had been recognized overtly on the first encounter. These results are interpreted within the
framework of an interactive activation model of face recognition.

Body checking and avoidance and the core features of eating disorders among obese men and women seeking bariatric surgery 总被引:1,自引:0,他引:1

This study examined two aspects of body checking and avoidance, and their relations to the core psychopathology of eating disorders (EDs), in severely obese men and women seeking bariatric surgery. A consecutive series of 260 (44 male and 216 female) gastric bypass candidates were administered measures to assess body checking and avoidance, binge eating, restraint, and overevaluation of weight and shape. The majority of patients reported regularly pinching areas of their body to check for fatness and avoided wearing clothing that made them particularly aware of their body. Significant associations were observed between checking and restraint, and between avoidance and binge eating. Both checking and avoidance behaviors were significantly associated with overevaluation of weight and shape. The positive associations between each of the two behaviors (body checking and avoidance) with overevaluation of weight/shape remained significant even after controlling for the effects of avoidance on body checking and vice versa. Stepwise multiple regression analyses revealed that binge eating, body checking, and avoidance behaviors made significant unique contributions and jointly accounted for 22-25% of the variance in overevaluation of weight and shape, respectively. This study documents the presence of eating disorder psychopathology among severely obese patients seeking bariatric surgery. The findings support the view that body checking and avoidance behaviors are manifestations of overevaluation of weight and shape and disordered eating. 相似文献

This study examined the psychometric properties of the Revised Child Anxiety and Depression Scale (RCADS) in a clinical sample of 513 youth referred for mental health assessment at a university clinic. Internal consistency and factor analysis provided support for the factorial validity of the RCADS. Convergent and discriminant validity tests against both clinical interview and self-report criteria also suggested favorable properties of the RCADS. In comparative tests with traditional measures of anxiety and depression, the RCADS generally showed greater correspondence to specific diagnostic syndromes. Clinical cutoffs are reported for the purposes of future clinical and research applications. 相似文献

This study evaluated the efficacy of adding contingency management techniques to vocational rehabilitation (VR) to improve treatment outcome as measured by entry into competitive employment. Nineteen dually diagnosed veterans who entered VR in the Veterans' Administration's compensated work therapy (CWT) program were randomly assigned to CWT (n = 8) or to CWT with enhanced incentives (n = 11). Over the first 16 weeks of rehabilitation, those in the incentives condition could earn up to dollar 1,006 in cash for meeting two sets of clinical goals: (a) remaining abstinent from drugs and alcohol and (b) taking steps to obtain and maintain a competitive job. Results indicate that relative to participants in the CWT-only group, those in the incentives condition engaged in more job-search activities, were more likely to remain abstinent from drugs and alcohol, were more likely to obtain competitive employment, and earned an average of 68% more in wages. These results suggest that rehabilitation outcomes may be enhanced by restructuring traditional work-for-pay contingencies to include direct financial rewards for meeting clinical goals. 相似文献

Pediatric psychologists use the tools of assessment to evaluate the psychological functioning of youth with chronic and acute medical illnesses. This study is an exploration of the use of a performance-based measure, the Hand Test (HT; Wagner, 1983), with pediatric medical patients. A sample of medical inpatients (n = 27) and psychiatric outpatients (n = 24) were administered the HT, a self-report measure, and a parent-report behavior rating scale. Results indicate that the psychiatric group scored higher than the medical group on HT Aggression, Withdrawal, and Pathological scores. The Aggression (d = 0.90) and Pathological (d = 0.80) variables were particularly robust in differentiating between groups, but the Crippled variable did not differ between groups. Hierarchical logistic regression demonstrated the incremental validity of the HT over behavior ratings alone in the classification of clinical groups. Analyses indicated that the HT can add important information in the differentiation of medically ill children from those with psychological disturbance. 相似文献

Processing of a probe stimulus can be affected either positively or negatively by presenting a related stimulus immediately before it. According to structural accounts, such effects occur because processing of the prime activates or inhibits the mental representation of the probe before it is presented. In contrast, transfer-appropriate processing accounts suggest that success in processing a probe depends on resources made available by earlier experiences of related stimuli. The authors manipulated the similarity between the prime and probe on color, lexical status, and orthographic structure, requiring either lexical decision or color identification on each. The authors observed a complex pattern of positive and negative transfer that cannot easily be explained through activation-inhibition of mental structures. Instead, that pattern provides evidence in favor of transfer-appropriate processing. 相似文献

The authors examine the repetition blindness effect--the failure to report one of the occurrences of a word presented twice in a rapid list. This phenomenon has been ascribed to inhibitory processes that prevent immediate tokenization of the 2nd occurrence of a repeated word. The authors present several kinds of evidence against that account, including observations that repetition blindness (a) does not occur when repetitions are not embedded in a list of familiar orthographic units, (b) is alleviated by precuing the subject with the identity of the word that may repeat within a rapid list, and (c) can be caused by cues presented after the list, when the opportunity for inhibition has passed. It is proposed that repetition blindness can better be understood through the principles of construction and attribution. 相似文献

This article relies upon structural symbolic interactionism and five of its organizing concepts (i.e. symbols, the definition of the situation, roles, socialization and role-taking, and the self) to put forth a novel conceptual framework for understanding the terrorist identity. In order to demonstrate the practical utility of the framework, applications to various terrorist groups around the globe are incorporated into the analysis. Overall, both the theoretical and application work help reorient the academic and practitioner behavioral science communities to the importance of culture, self, and society when investigating one's membership in and identity through militant extremist organizations. Given the unique approach taken by this article, several provisional implications are delineated. In particular, future research on terrorism, strategies linked to counter-terrorism, legal and public policy reform, and the relevance of utilizing a sociologically animated social psychology in the assessment of other forms of criminal behavior are all very tentatively explored. 相似文献

Speech comprehension difficulties in older adults: cognitive slowing or age-related changes in hearing? 总被引:3,自引:0,他引:3
Speech comprehension declines more rapidly in older adults than in younger adults as speech rate increases. This effect is usually attributed to a slowing of brain function with age. Alternatively, this Age X Speed interaction could reflect the inability of the older adult's auditory system to cope with speed-induced stimulus degradation. When the authors speeded speech in a way that produced minimal degradation, both age groups were equally affected. However, when speech was speeded using other methods, word identification declined more in older than in younger adults. Hence, auditory decline rather than cognitive slowing may be responsible for older adults' poorer performance in speeded conditions. 相似文献
