This study assessed the construct validity of the Revised Behavior Problem Checklist (RBPC) by measuring attention, autonomie arousal, and personality in 40 behaviorally disordered children aged 7 to 15 years. Conduct Disorder and Socialized Aggression subscales were characterized by high Psychoticism, Impulsivity, and Lie personality scores, by lower heart rate levels, and by more errors on a continuous performance reaction-time task. Conversely, Attention Problems, Anxiety Withdrawal, and Motor Excess were characterized by greater variability in reaction times. Conduct Disorder alone was related to an external locus of control, while only Attention Problems was characterized by low scores on the WISC Freedom from Distraction factor. These differential relationships suggest (a) support for the construct validity of the RBPC, (b) that antisocial behavior and hyperactivity/attention deficits are dissociated disorders, and (c) that hyperactivity/attention deficits may be characterized by fluctuations in the allocation of attentional resources rather than a core structural deficit in attention. 相似文献

Silberberg and Ziriax (1985) report that a modification of Vaughan's (1981) procedure produces results inconsistent with melioration (the position advocated by Vaughan) but consistent with a process they term molecular maximizing. Here it is argued that the theory of molecular maximization is not sufficiently unambiguous that researchers other than the developers can test its predictions, and that in any case none of the data presented by Silberberg and Ziriax are both clearly consistent with molecular maximization and inconsistent with melioration. 相似文献

How do people go about choosing between alternatives in relatively simple settings? This study explores some of the variables that past work suggests may be relevant. Volunteer subjects worked for money in six procedures in which the probability of a payment from either of two alternatives was 1.0, but the rate of pay (i.e. the speed with which a payment was delivered or the size of the payment) interacted with the subjects recent allocation of choices, which we define as the ‘internalities’. Because of the internalities, choosing the currently more profitable alternative did not maximize total earnings. Subjects were more likely to fail to maximize when the interaction between present pay and past choices was spread over longer sequences of choices, or when the reward variable was the speed, rather than the value, of each payment. Subjects often disregarded the internalities and were instead guided by the current yields of the two alternatives, which is a frequently observed tendency, called ‘melioration’, in experiments on choices by animals. The tendency toward melioration was only partially counteracted by explicit instructions on how to maximize earnings. We discuss a theoretical framework for melioration that postulates both motivational and cognitive sources. 相似文献

In a new series of regular reports, research groups active in personnel psychology from a number of countries will present a briefing on work-in-progress. In the first in this series, the HRM Group at the Department of Psychology, University of Nottingham, describe their ongoing work into organization change and training validation, employee socialization, computer-based testing, and personality test construction and assessment centre validation. 相似文献

We describe a plan for integrating an experimental control language, PsyScope, into under-graduate laboratory exercises of perceptual and cognitive experiments on Macintosh computers. PsyScope is a powerful and versatile system with which students can modify standard research paradigms and execute experiments of their own design, thus facilitating student-initiated independent research. Data are summarized with a general-purpose program, PsySquash, for import into Statview or SuperAnova for further analysis. This system provides an effective means of implementing student projects. 相似文献

Application of modal logic to programming 总被引:1,自引:0,他引:1
Vaughan R. Pratt 《Studia Logica》1980,39(2-3):257-274
The modal logician's notion of possible world and the computer scientist's notion of state of a machine provide a point of commonality which can form the foundation of a logic of action. Extending ordinary modal logic with the calculus of binary relations leads to a very natural logic for describing the behavior of computer programs.This research was supported by NSF Grant No. MSC - 7804338. 相似文献

Several recent experiments have demonstrated that modulation of the facial expressive response is accompanied by changes in autonomic arousal and subjective response to painful stimuli. The present study asked whether facial self-regulation may also bring about changes in covert vicarious emotional experience. Three groups of subjects were exposed to a videotaped model displaying intermittent pain to shock in a differential vicarious autonomic conditioning paradigm. Subjects in the inhibit and amplify groups were asked, respectively, (a) to inhibit their facial muscles or (b) to pose a facial response of pain when the model was shocked. It was predicted that the inhibit group would show less autonomic arousal to the model's expressive display (empathy) and less conditioning (as measured by skin conductance and heart rate change), and the amplify group more empathy and conditioning, than a third group who was given no facial instruction. In fact, the amplify group showed more skin conductance arousal, heart rate acceleration, and activity in response to the model's expressive display of pain than did the other two groups (which were not different from each other), but no more autonomic or facial conditioning. The overall pattern of physiological data is interpreted as generally supportive of a facial feedback theory of emotion: where significant between-groups' differences were obtained in facial activity, as in vicarious instigation, autonomic arousal differences also emerged; where no expressive differences were obtained, as in vicarious conditioning, no differences in autonomic arousal were found. 相似文献
