The purpose of this study was to investigate the use of a choice reaction time task, during which slides of sexually explicit and neutral stimuli were used as an interference task, to differentiate between groups of individuals on the basis of their sexual preference. Twenty subjects, in each of the four groups (heterosexual males, heterosexual females, homosexual males, and homosexual females), participated in this study. Sexual orientation was determined by self-report. Subjects were given a choice reaction time with interference task, followed by a recall incidental learning task. A significant higher-order interaction was found among gender, orientation, and stimulus type for all four groups. This interaction indicated a longer reaction time to slides depicting preferred sexual partners than to nonpreferred sexual partners or neutral scenes. These results indicate that sexual arousal does interfere with cognitive processing. A main effect for gender was found for the incidental learning task, with males having the fewest errors. 相似文献

There are a number of reasons for being interested in uncertainty, and there are also a number of uncertainty formalisms. These formalisms are not unrelated. It is argued that they can all be reflected as special cases of the approach of taking probabilities to be determined by sets of probability functions defined on an algebra of statements. Thus, interval probabilities should be construed as maximum and minimum probabilities within a set of distributions, Glenn Shafer's belief functions should be construed as lower probabilities, etc. Updating probabilities introduces new considerations, and it is shown that the representation of belief as a set of probabilities conflicts in this regard with the updating procedures advocated by Shafer. The attempt to make subjectivistic probability plausible as a doctrine of rational belief by making it more flowery — i.e., by adding new dimensions — does not succeed. But, if one is going to represent beliefs by sets of distributions, those sets of distributions might as well be based in statistical knowledge, as they are in epistemological or evidential probability. 相似文献

In addition to repeated reexperiencing of the event, the delayed effects of severe psychological trauma, i.e., post traumatic stress disorder (PTSD), present a paradoxical mix of symptoms. There is enhancement of the self-preservative catecholamine states; anger and fear with a contrasting sense of meaninglessness and a blunting of the emotional responses of the attachment behavior so critical for species preservation. Hormonally, there is a striking separation of the catecholamine response, which stays elevated and that of the hypothalamo-pituitary-adrenal (HPA) axis, which may remain at normal levels. Pathophysiologically, the reexperiencing of the trauma and the arousal may be associated with dysfunction of the locus coeruleus, amygdala and hippocampal systems. This article explores the consequences of an additional dysfunction: a dissociation of the hemispheres that appears to be responsible for the alexithymic avoidance and failure of the cortisol response that so often follow severe psychological trauma. There is neurophysiological evidence that the left and right hemispheres subserve different emotional sets that correspond to “control” and “appraisal,” i.e., very approximately to the self and species preservative behavioral complexes, respectively. Several studies point to physiological dissociation of hemispheric functions during alexithymia. This raises the question: What has been lost if in this condition the right side no longer fully contributes to integrated cerebral function? Right hemispheric damaged children lose critical social skills and in adults the related sense of familiarity critical for bonding is lost. Such losses of social sensibilities may account for the lack of empathy and difficulties with bonding found in sociopathy and borderline personality: conditions now believed to result from repeated psychological trauma during development. On the other hand, systems that promote right hemispheric contributions provide solacing access to a “Higher Power.” They also appear to protect against socially disordered behavior, substance abuse, the failure of the HPA axis and some aspects of the pathophysiology of chronic disease. 相似文献

Using a judgment and component analysis of facial actions, 14 muscle-contraction headache (MCH) patients were videotaped in headache and nonheadache states. In addition, patients were also required to undergo a resting physiological assessment (frontalis electromyography, temporal blood volume pulse, and heart rate), reaction-time task, and complete self-report measures of pain state and mood. Headache and nonheadache state of MCH patients were reliably identified by 20 observers. Characteristics of facial expressions that occurred most frequently in the headache state included furrowed eyebrows, closed eyes, slow eye blinks, lip pursuing, facial grimacing, and flat facial affect. Headache state was also associated with increased latency to respond to an auditory tone and mood disturbances, but no differences in baseline physiological activity were observed. Our findings provide support for the utility and clinical relevance of judgment and component analysis of facial actions in MCH patients. 相似文献

Like experts in other fields, expert computer programmers can recall at a glance far more information relevant to their field than novices can. One explanation for this difference is that experts not only have more information, they have it better organized into meaningful chunks. In this paper, we infer the details of individual programmers' chunks of key programming concepts using the Reitman—Rueter (Cognitive Psychology, 1980, 12(4), 554–581.) technique for inferring tree structures from recall orders. Differences in organizations accompany skill-level differences. Beginner programmers' organizations show a rich variety of common-language associations to these programming concepts; Intermediate programmers show mixtures of programming and common-language associations; and Experts show remarkably similar, but not identical, organizations based clearly on programming knowledge. 相似文献

This study illustrates the use of a response cost token system to decrease inappropriate behaviors of mainstreamed students in the regular classroom milieu. Data were taken on a student's inappropriate request for teacher attention and another student's inappropriate verbalizations. A reversal design was employed. Results showed that a response cost token system was a viable and effective method for decreasing inappropriate behaviors of mainstreamed students in the regular classroom. Reasons for the effectiveness of this technique were discussed. 相似文献

Tucker's three-mode common factor analysis is used to explore the intrinsic individual differences in a figural, disjunctive conceptual behavior task. The results reveal differential shifts in the structure of the individual differences during concept identification. Individual patterns can be described by five factors, each of which specifies the parameter vales for the shape of the individual performance functions. A three-way core further identifies the nature of the individual differences factors. These results indicate that averaged curves for the separate response measures would not have adequately reflected the individual data in this sample. The present findings are consistent with earlier work and suggest that a better approach to the study of complex human behavior is to identify the individual differences intrinsic to the situation before mapping antecedent influences on the dimensionality of the behavior. 相似文献
