Attention Deficit Hyperactivity Disorder (ADHD) is a common and impairing neuropsychiatric disorder with onset at preschool age. Although a significant amount of progress has been made investigating the neurobiology of this disorder, its precise etiology still remains unclear. Converging evidence from studies of the neuropharmacology, genetics, neuropsychology, and neuroimaging of ADHD imply the involvement of fronto-striatal circuitry in ADHD. However, while it does appear that poor inhibitory control and the deficits in fronto-striatal circuitry associated with it are central, there is evidence to suggest that more posterior cerebral areas are also implicated in this disorder. Anatomical studies suggest widespread reductions in volume throughout the cerebrum and cerebellum, while functional imaging studies suggest that affected individuals activate more diffuse areas than controls during the performance of cognitive tasks. The future impact of new MR imaging methodologies on the field is discussed.  相似文献

HYPERFEMININITY AND INFLUENCE   总被引:1,自引:1,他引:0  
Murnen and Byrne (1991) have defined hyperfemininity as an exaggerated adherence to a feminine gender role as it relates to heterosexual relationships. Hyperfeminine women believe their success is determined by maintaining a romantic relationship with a man, and that their sexuality can be used to maintain this relationship. Extrapolating from theory concerning gender and status, including expectation states theory, it was hypothesized that a woman's expression of hyperfeminine attitudes would lead male college student participants to agree with her in response to a persuasive speech because it would indicate her compliance with women's subordinate status. It was found that men (but not women) who listened to a very hyperfeminine (high) speaker agreed with her more than did men who heard a mildly hyperfeminine (low) speaker, despite the fact that the high hyperfeminine speaker was judged less competent and knowledgeable. Implications of the results, including the idea that the sexual objectification of women perpetuates women's subordinate status, were discussed.  相似文献

We examined correspondence between preference assessment outcome and within‐session patterns of responding in one subject with autism. Responding maintained by a single highly preferred item resulted in a greater total number of responses, a slower decline in within‐session response rates, and a greater proportion of short interresponse times compared to responding maintained by varied moderately preferred (MP) stimuli. Presenting varied MP stimuli within the same session produced greater levels and more sustained responding than presenting those same stimuli individually.  相似文献

The Social Phobia and Anxiety Inventory (SPAI) is a new instrument composed of social phobia and agoraphobia subscales. The latter scale is used to detect social anxiety that may result from agoraphobia. The SPAI's construct validity was assessed through several procedures. First, confirmatory factor analyses were conducted to validate the existence of the two subscales. Second, exploratory factor analyses examined the underlying structure of the social phobia subscale. Third, a Q factor procedure determined if different anxiety diagnostic groups could be differentiated by their SPAI response pattern. The results confirmed the utility of the two SPAI subscales and identified a number of dimensions contained within the social phobia subscale which differed depending upon the specific subject sample. In addition, the complaints of social phobies appeared more homogeneous than those of an agoraphobic comparison group. The results are discussed in terms of construct validity and the sensitivity of the SPAI to various dimensions of social phobia fears.This study was supported in part by NIMH Grants 41852, 30915, 18269, and 16884.  相似文献

The experience of mixed emotions increases with age. Socioemotional selectivity theory suggests that mixed emotions are associated with shifting time horizons. Theoretically, perceived constraints on future time increase appreciation for life, which, in turn, elicits positive emotions such as happiness. Yet, the very same temporal constraints heighten awareness that these positive experiences come to an end, thus yielding mixed emotional states. In 2 studies, the authors examined the link between the awareness of anticipated endings and mixed emotional experience. In Study 1, participants repeatedly imagined being in a meaningful location. Participants in the experimental condition imagined being in the meaningful location for the final time. Only participants who imagined "last times" at meaningful locations experienced more mixed emotions. In Study 2, college seniors reported their emotions on graduation day. Mixed emotions were higher when participants were reminded of the ending that they were experiencing. Findings suggest that poignancy is an emotional experience associated with meaningful endings.  相似文献

In this article we first identify and provide evidence for feminist contributions to counseling psychology in four broad areas. These are policy and leadership in the field, theory and research, training and practice, and recognition of feminist scholarship and contributions by women. In view of the evidence, we conclude that feminist perspectives are irrevocably changing the field of counseling psychology by stimulating the rethinking of its premises and models with regard to normal development and by developing new approaches to inquiry and practice.  相似文献

Intrapsychic factors, including the dissociation of childhood wounds, rendered a mandated reporter of child abuse impotent to report a child's disclosure of abuse. The defenses of projective identification, splitting, denial, devaluation, and cognitive impairment prevented her from taking proper action. Passivity trained into her by the church and society reinforced her refusal to act to protect the child.  相似文献
