V. M. Sloutsky and A. V. Fisher reported 5 experiments documenting relations among categorization, induction, recognition, and similarity in children as well as adults and proposed a new model of induction, SINC (similarity, induction, categorization). Those authors concluded that induction depends on perceptual similarity rather than conceptual knowledge. Despite the useful contributions of this work, there are some important limitations. The experimental designs examined a limited range of phenomena that are not the most revealing about the use of nonperceptual information. The main results involved a simple triad task, for which the SINC model's predictions are equivalent to the predictions of previous models of inductive reasoning. It is also unclear whether the SINC model can account for the observed relations between similarity and recognition. Implications for future work on induction and related cognitive activities are discussed. 相似文献

How do people walk to a moving target, and what visual information do they use to do so? Under a pursuit strategy, one would head toward the target's current position, whereas under an interception strategy, one would lead the target, ideally by maintaining a constant target-heading angle (or constant bearing angle). Either strategy may be guided by the egocentric direction of the target, local optic flow from the target, or global optic flow from the background. In four experiments, participants walked through a virtual environment to reach a target moving at a constant velocity. Regardless of the initial conditions, they walked ahead of the target for most of a trial at a fairly constant speed, consistent with an interception strategy (experiment 1). This behavior can be explained by trying to maintain a constant target-heading angle while trying to walk a straight path, with transient steering dynamics. In contrast to previous results for stationary targets, manipulation of the local optic flow from the target (experiment 2) and the global optic flow of the background (experiments 3 and 4) failed to influence interception behavior. Relative motion between the target and the background did affect the path slightly, presumably owing to its effect on perceived target motion. We conclude that humans use an interception strategy based on the egocentric direction of a moving target. 相似文献

Psychometric properties of the life events checklist 总被引:1,自引:0,他引:1
The Life Events Checklist (LEC), a measure of exposure to potentially traumatic events, was developed at the National Center for Posttraumatic Stress Disorder (PTSD) concurrently with the Clinician Administered PTSD Scale (CAPS) to facilitate the diagnosis of PTSD. Although the CAPS is recognized as the gold standard in PTSD symptom assessment, the psychometric soundness of the LEC has never been formally evaluated. The studies reported here describe the performance of the LEC in two samples: college undergraduates and combat veterans. The LEC exhibited adequate temporal stability, good convergence with an established measure of trauma history -- the Traumatic Life Events Questionnaire (TLEQ) -- and was comparable to the TLEQ in associations with variables known to be correlated with traumatic exposure in a sample of undergraduates. In a clinical sample of combat veterans, the LEC was significantly correlated, in the predicted directions, with measures of psychological distress and was strongly associated with PTSD symptoms. 相似文献

The purpose of this study was to investigate the extent to which subroles inherent in managerial positions are gender-typed and whether men or women engage in relatively more gender typing of managerial roles. We obtained perceptions of 19 management subroles from 263 business students in the United States Results confirmed predictions that some subroles are viewed as more feminine in nature whereas other subroles are perceived as more masculine. Male respondents saw most subroles as more masculine in nature than did female respondents. Results are discussed in terms of implications for researchers studying management, as well as for managers in the workplace. 相似文献

It is argued that analyzing and listing reasons can lead to poorer predictions because reasoners either access information inappropriate to the task or have difficulty integrating the information they do bring to mind. To test this hypothesis, self-described basketball experts predicted the outcomes of actual basketball games in a national tournament. Half of the participants were asked to analyze and list reasons for their predictions before making them, and half were told explicitly not to analyze their reasons. Compared to nonreasoners, reasoners predicted fewer winners of the games and predicted margins of victory that differed more from both the actual margins of victory and the margins of victory predicted by experts. The relationship between expertise and reasons analysis, and the implications of the results for other domains of prediction are discussed. 相似文献

A reanalysis of a large multi-generational,predominantly Caucasian sample of adults found a largegender difference in self-reported depression involvinganxiety, appetite and sleep disturbance, and fatigue (anxious somatic depression) butnot in pure depression unaccompanied bymany of these other symptoms, replicating earlierfindings on high school and college samples. Anxioussomatic depression was prevalent among women whosefathers reported attitudes of male superiority and amongwomen whose mothers reported emphasizing the importanceof professional success but feeling that the jobs they held were not respected by others. Anxioussomatic depression, but not pure depression, was foundto be prevalent among women who did not attend collegeand among those who attended college but felt that the jobs they held were not respected byothers. 相似文献

Two experiments explored the role of mimicry and self-perception processes in emotional contagion. In Study 1, 46 subjects watched two brief film clips depicting an episode of startled fear. In a separate procedure, subjects adopted facial expressions of emotion, and reported whether the expressions had caused them to feel corresponding emotions. Those who reported feeling the emotions were identified as more responsive to self-produced cues for feeling. Subjects who visibly moved to mimic the behavior of the actor were significantly more likely to be those who were more responsive to self-produced cues. In Study 2, 57 subjects watched three film clips depicting happy people. During clips when they inhibited the movements of their faces, subjects reported less happiness than during clips when they moved naturally and were able to mimic, or when they exaggerated their movements. This effect occurred only among subjects who, in a separate procedure, had been identified as more responsive to self-produced cues.The authors would like to thank Paul Ekman, Jerry Ginzburg, and an anonymous reviewer for very helpful suggestions for ways to improve the paper. 相似文献

Recent research suggests that many females who mature during periods of great change in women's roles develop, beginning at adolescence, depressive symptomatology combined with such somatic problems as headache, dyspnea, insomnia, disordered eating, and preference for thinness. In this study of possible psychological mechanisms underlying the apparently paradoxical development of such symptomatology during periods of increased opportunity for women, 20% of females attending a suburban high school reported concerns regarding the limited achievements of their mothers and the limitations being female had placed upon their mothers. Compared to other female students, these respondents exhibited a greater correlation between depressive and somatic symptomatology and a higher prevalence of depression combined with somatic symptomatology. Prevalence of combined symptomatology was particularly high among respondents who also reported paternal biases against females and among those who indicated concerns regarding the limitations that being female had placed upon themselves. 相似文献
