To determine which variables impact developmental task attainment for young adults from divorced families, respondents completed demographic questions, the young adult version of the Personal Authority in the Family System Questionnaire, and the three family relationship subscales of the Family Environment Scale. Of the factors assessed, results suggest that the quality of post-divorce family functioning is the most salient predictor of development for young adults from divorced families. Additionally, although conflict and cohesion have unique effects on task attainment for young adults, expressiveness appears to be the dimension of post divorce family functioning most related to young adult development.  相似文献

This research attempts to assess the role of preexisting self-perceptions as moderators of individuals' reactions to preferential and merit-based selection. A laboratory experiment was conducted in which female participants were recruited to work on a temporary “job.” Participants were randomly “hired” for the job either because they passed a preemployment qualifying test or because of their gender. Results supported hypothesized self-consistent reactions to the hiring conditions among individuals differing in preexisting self-efficacy. Compared to high self-efficacy participants, lower self-efficacy individuals responded to preferential hiring with lower eventual task performance. Low self-efficacy individuals were also less apt to attribute performance during selection to ability when hired under a merit-based procedure, compared to high self-efficacy participants.  相似文献

Sex differences in ADHD: Conference summary   总被引:8,自引:0,他引:8  
Clinical samples of attention deficit hyperactivity disorder (ADHD) have been dominated by males. Consequently, female manifestations and sex differences have been relatively neglected in the extensive ADHD research. Because ADHD is so common (3% to 5% of school children) and chronic (lifelong in many cases), even a small proportion of females multiplied by such a large base means hundreds of thousands of girls and women with ADHD, a significant public health problem. An NIMH conference concluded that research is needed not only on sex differences related to ADHD, but also on manifestations of ADHD in females as such. Areas of focus should include differences in life course (sex-differential age effects); effects of hormones; effects of ADHD parenting (in utero and postnatal) on the next generation; response to and implications for design of psychosocial treatment; effects of differential comorbidity; normative background sex differences that influence the manifestation of ADHD; differences in development of verbal fluency and social behavior; possible interactions of sex and ethnicity; a prospective study of both sex offspring of ADHD adults; and such methodological issues as appropriate instruments and diagnostic thresholds, power to prevent false negatives, valid impairment measures, validity and reliability of child self-reports, and more inclusive samples (all three subtypes: inattentive, hyperactive-impulsive, and combined).The following participants in the November 16–17, 1994, NIMH Conference on Sex Differences in ADHD may be considered ghost co-authors of the contents in this summary. Special thanks are due to Euthymia Hibbs, Ph.D., co-organizer of the conference; Peter Jensen, M.D., who suggested the successful format; Delores Parron, Ph.D., who gave much helpful advice on the conference arrangements; Emily Areia, Ph.D., who thoroughly critiqued the summary; Joan Cole, who helped abstract the recorded proceedings; and Jose Bauermeister, Ph.

In this investigation, the relative importance of the effects of anticipated test format and anticipated test difficulty on performance was examined by simultaneously manipulating both. Experiments 1 and 2 showed that test performance was affected more by anticipated test format than by anticipated test difficulty. This suggests that the superior performance of subjects who had anticipated a recall test versus those who had anticipated a recognition test, reported here and in previous studies, is more likely to be due to anticipating a recall format than to anticipating a more difficult test. Experiment 2 showed that subjects who had anticipated a recall test studied longer than subjects who had anticipated a recognition test, even when recall tests were less difficult than recognition tests. One explanation for this finding is that subjects inaccurately monitor the relative difficulty of tests across test formats. Subjects rated recall items as more difficult than recognition items, even when recall items are actually less difficult (Experiment 3). These findings suggest that a priori metacognitive knowledge may reduce the accuracy of on-line metacognitive monitoring.  相似文献

Unfairness, Anger, and Spite: Emotional Rejections of Ultimatum Offers   总被引:1,自引:0,他引:1  
This paper addresses an anomaly in experimental economics, the rejection of ultimatum offers, and uses a psychological explanation for this essentially economic event. The wounded pride/spite model predicts that informed, knowledgeable respondents may react to small ultimatum offers by perceiving them as unfair, feeling anger, and acting spitefully. Results of a large scale experiment support the model, showing that rejections were most frequent when respondents could evaluate the fairness of their offers and attribute responsibility to offerers. In addition, anger was a better explanation of the rejections than perceptions that the offers were unfair. The discussion addresses the rarely studied but frequently observed emotions that negotiations provoke.  相似文献

The concept of corporate consciousness is defined and discussed. In response to Campion and Palmer (1996), it is asserted that corporate consciousness is not a construct related to conscientiousness or moral responsibility, but an entirely new paradigm, related to awareness and information processing; the concept is cognitive, not metaphysical. Corporate consciousness serves as a framework for understanding the current trend within organizations toward greater awareness of societal realities, and of the organization's impact within larger systems. This framework borrows heavily from the cognitive, social, and organizational psychological literature and can be understood from both micro and macro levels of analysis. Also discussed are the issues of why and how to study corporate consciousness, as well as implications for the organizational practitioner.  相似文献

The effect of contextual constraint on eye movements in reading was examined by asking subjects to read sentences that contained a target word that varied in contextual constraint; high-, medium-, or low-constraint target words were used. Subjects fixated low-constraint target words longer than they did either high- or medium-constraint target words. In addition, they skipped high-constraint words more than they did either medium- or low-constraint target words. The results further confirm that contextual constraint has a strong influence on eye movements during reading.  相似文献

In this paper I formulate an approach for evaluating probabilistic forecasts in terms of signal detection theory. Signal detection theory provides a powerful perspective for this type of problem, and a rich empirical background including methodological tools as well as an extensive body of research in many domains. I propose procedures which emphasize the maximization of expected utility for the decision maker who uses the forecasts. Further, I suggest approaches to obtaining indices of calibration and resolution within this framework. I also present arguments that the proposed indices will exhibit the same basic properties as do decompositions of Brier's (1950, Monthly Weather Review, 78, 1–3) mean probability score. However, the properties may be reflected in different ways, and hence, the present methods may lead to different conclusions about forecasting ability. Finally, I argue that the use of an expected utility loss function makes this approach more appropriate for practical applications as well as for theoretical research than other procedures with more arbitrary loss functions.  相似文献

This study was designed to investigate the role of sensory reinforcement in the motivation of self-stimulation. If self-stimulatory behavior is maintained by its sensory consequences, such as the proprioceptive, auditory, or visual stimulation it produces, then such behavior should extinguish when those sensory consequences are not permitted. The present study introduces a new procedure, Sensory Extinction, in which certain sensory consequences are masked or removed, to examine whether self-stimulation is operant behavior maintained by sensory reinforcement. The effectiveness of Sensory Extinction was assessed by a reversal design for each of three autistic children, and the results showed the following. First, self-stimulation reliably extinguished when a certain sensory consequence was removed, then increased when that consequence was permitted. This was replicable within and across children. Second, different Sensory Extinction procedures were required for different self-stimulatory behaviors, since the sensory reinforcers supporting them were idiosyncratic across children. Finally, regarding clinical gains, the data suggest that Sensory Extinction may be a relatively convenient and rapid alternative for the treatment of self-stimulation. The present findings extend the efficacy of extinction as a behavior-modification technique to instances in which the reinforcer is purely sensory. The implications of these results for the treatment of other forms of deviant behavior are discussed.  相似文献

A model of subjective magnitude comparisons is explored, which assumes that subjects compare symbolic stimulus magnitudes with respect to a reference point. The reference point may be established implicitly by the question (e.g., “Which is larger?” vs “Which is smaller?”) or be presented explicitly (e.g., “Choose the stimulus closer to X.”). The model was tested in five experiments in which subjects judged which of two comparison digits was closer to (or further from) a reference digit. Regression analyses in three experiments revealed that reaction time depended on the ratio of the distances from the comparison items to the reference point. The other two experiments provided evidence that subjects can strategically vary the processes by which they compare stimuli to a reference point. The results indicated that subjects can perform various types of “analog arithmetic” using either the linear number scale or a nonlinear scale of subjective digit magnitude.  相似文献
