This article examines the theoretical basis of decision-making deficits exhibited by cocaine abusers in a laboratory decision-making
task first described by Bechara, Damasio, Damasio, and Anderson (1994). A total of 12 male cocaine abusers and 14 comparison
subjects performed the task, and the cocaine group performed significantly worse than the comparison group. A cognitive modeling
analysis (Busemeyer & Stout, 2002) was used to estimate three parameters that measure importance of the cognitive, motivational,
and response processes for determining the observed performance deficit. The results of this analysis indicated, for the first
time, that motivational and choice consistency factors, but not learning/ memory were mainly responsible for the decision-making
deficit of the cocaine abusers in this task. 相似文献

it is the worst oppression, that is done by colour of justice --Sir Edward Coke A sign that says "men only" looks very different on a bathroom door than on a courthouse door. --U.S. Supreme Court Justice Thurgood Marshall "Is Parkinson's the toughest opponent you've ever faced, Muhammed?" someone asked. "Toughest was my first wife," he said. --Former World Heavyweight Boxing Champion Muhammed Ali A great deal of sociological evidence has been collected in the past three decades on the prevalence of abuse among adult heterosexual partners in domestic relationships of some degree of permanence. Partly as a result of this information, partner abuse has been identified as an important social ill that must be addressed aggressively through public-awareness campaigns, the funding of a broad range of support services, and the re-training of law-enforcement authorities--including police, prosecutors, and judges. However, in at least one important respect, these policy initiatives diverge substantially from what the sociological data, which ostensibly motivates them, would indicate: they have been, to date, overwhelmingly gender specific. That is, partner abuse is routinely portrayed and acted upon as though it were almost exclusively about men abusing and victimizing innocent women and, by extension, their children--despite the overwhelming sociological evidence that a significant amount of abuse is also suffered by male partners. Persistent anecdotal reports from victims and even some participants in the law-enforcement system suggest that this ideological emphasis on the male as perpetrator has had a deleterious effect on the impartial administration of justice, resulting in men being treated much more harshly than women who are accused of partner violence. This study attempts to determine whether the anecdotes are scientifically supportable. 相似文献

This study describes the effects of different weekly work intensity levels on adolescent functioning in a sample of 3,083 high school students in rural South Texas, where economically disadvantaged and Hispanic youth are heavily represented. Anonymous surveys were conducted in 10th- and 12th-grade students' classrooms in 1995. The following effects were associated with long hours of weekly employment during the school year: (1) decreased performance/engagement in school and satisfaction with amount of leisure time, and (2) increased health risk behaviors and psychological stress. The effects of school-year work on academic factors and health behaviors differed by grade, but not by race/ethnicity, parent education, or race/ethnicity and parent education considered together. It was concluded that parents and professionals should continue to monitor the number of weekly hours that students work during the school year. 相似文献

Cognitive behaviour therapy for eating disorders: a "transdiagnostic" theory and treatment 总被引:4,自引:0,他引:4
This paper is concerned with the psychopathological processes that account for the persistence of severe eating disorders. Two separate but interrelated lines of argument are developed. One is that the leading evidence-based theory of the maintenance of eating disorders, the cognitive behavioural theory of bulimia nervosa, should be extended in its focus to embrace four additional maintaining mechanisms. Specifically, we propose that in certain patients one or more of four additional maintaining processes interact with the core eating disorder maintaining mechanisms and that when this occurs it is an obstacle to change. The additional maintaining processes concern the influence of clinical perfectionism, core low self-esteem, mood intolerance and interpersonal difficulties. The second line of argument is that in the case of eating disorders shared, but distinctive, clinical features tend to be maintained by similar psychopathological processes. Accordingly, we suggest that common mechanisms are involved in the persistence of bulimia nervosa, anorexia nervosa and the atypical eating disorders. Together, these two lines of argument lead us to propose a new transdiagnostic theory of the maintenance of the full range of eating disorders, a theory which embraces a broader range of maintaining mechanisms than the current theory concerning bulimia nervosa. In the final sections of the paper we describe a transdiagnostic treatment derived from the new theory, and we consider in principle the broader relevance of transdiagnostic theories of maintenance. 相似文献

The tripartite model of anxiety and depression: symptom structure in depressive and hypertensive patient groups 总被引:2,自引:0,他引:2
Marshall GN Sherbourne CD Meredith LS Camp P Hays RD 《Journal of personality assessment》2003,80(2):139-153
The structure of self-reported symptoms representative of the tripartite model was examined using data drawn from the Medical Outcomes Study (Tarlov et al., 1989). Participants were persons who had been diagnosed 48 months previously as suffering from either depression (N = 315) or hypertension (N = 403). Results of confirmatory factor analyses were broadly consistent with the tripartite model (L. A. Clark & Watson, 1991). Factors emerged corresponding to each of the 3 posited first-order dimensions of negative affect, positive affect, and physiologic arousal. Nonetheless, some discrepancies were found between the observed data and the hypothesized tripartite model. First, the obtained physiologic arousal factor was best viewed as reflecting nonspecific somatic distress rather than physiologic arousal. Finally, although differentiable in the strictest statistical sense, all three domains were significantly correlated (.36 to.86, absolute value). In particular, contrary to the tripartite model, positive and negative affect covaried markedly (-.81 to -.86). Findings raise issues concerning the utility of the tripartite model as a heuristic framework for enhancing understanding of individual differences in normal mood as well as mood disorders. 相似文献

Longitudinal data from a representative sample of 1,978 Black and White adolescents were used to examine the role of personality in multiple risk or problem behaviors. Results indicate that covariation among diverse behaviors (educational underachievement, delinquent behavior, substance use, sexual behavior) can be adequately modeled by a single higher order factor, and that impulsivity and avoidance coping serve as generalized risk factors for involvement in these behaviors. Whereas none of the personality variables examined explained change in problem behaviors once established, avoidance coping prospectively predicted involvement among a subgroup of adolescents with little or no prior involvement. Results suggest that dysfunctional styles of regulating emotions and emotionally driven behaviors are core features of risky or problem behaviors during adolescence. 相似文献

The relationship between optimism and two potential sources of optimistic beliefs--promotion pride (based on a history of success in promotion regulation) and prevention pride (based on a history of success in prevention regulation)--was explored. Optimism was more strongly related to promotion pride than prevention pride (controlling for neuroticism), consistent with past work showing that anticipating success increases eagerness motivation but decreases vigilance motivation. This suggests that the psychology of prevention regulators is not captured well by the existing literature on optimism. Although prevention pride does not predict self-reports of well-being, it does predict adaptive functioning independent of optimism, neuroticism, and promotion pride. Promotion pride uniquely predicted a sense of purpose in life or goal directedness. Both promotion and prevention pride predicted active coping. It is argued that promotion and prevention pride tell us something unique and important about the role of successful self-regulation in determining quality of life. 相似文献
