Perceptual organization is thought to involve an analysis of bothtextural discontinuities andperceptual grouping. In earlier work, we found that textural discontinuities were detected normally even when visual attention was engaged elsewhere. Here we report how perceptual grouping is affected when visual attention is engaged by a concurrent visual task. To elicit perceptual grouping, we used the Gestalt demonstrations of grouping on the basis of proximity and of similarity. Four tasks were investigated, some requiring the observer to discriminate between horizontal and vertical grouping, and some requiring the observer to merely detect the presence or absence of grouping. Visual attention was engaged at the center of the display by a form identification task. The detection of a textural discontinuity served as a control task. Concurrent form identification conflicted with all four grouping tasks, resulting in a significant reduction of grouping performance in each case. No performance reduction was observed when either form identification or grouping discrimination was combined with the detection of a textural discontinuity. These results suggest that perceptual grouping and form identification compete for visual attention, whereas the detection of a textural discontinuity does not. 相似文献

This study examines the effects of informational cues on the attribution of success in a masculine task. Israeli managers (subjects) first evaluated the performance of a fictitious male/female manager and then attributed a cause to his/her success in attaining the managerial position. As predicted, performance evaluation affected the attribution and manager sex did not. An unexpected association between leadership style and attribution was found. Implications of these findings for female managers and for further research are considered. 相似文献

This is a survey of the prevalence of weight reducing and weight gaining in high school children. Our sample of 1,373 high school girls and boys was geographically, racially, and economically diverse. On the day of the survey, 63% of the girls and 16.2% of the boys reported being on weight reducing regimens; 9.1% of the girls and 28.4% of the boys were trying to gain weight. Most female reducers and male gainers were already normal weight. Compared to other racial groups, whites and Hispanics were more likely to be reducing, whereas blacks were more likely to be gaining. Exercise and moderate caloric reduction were most popular for weight reducing, and a small but significant number were regularly using fasting, vomiting, laxatives, and appetite suppressants. The direction of weight modification for girls and boys conformed to stereotyped physical ideals. The rate of weight reducing in female high school adolescents has increased significantly since similar surveys of American youths 20 years ago. 相似文献

An experimental simulation was conducted to examine potential differences in sensitivity to forces to supply and demand among male and female sex-typed jobs. Respondents faced with a labor shortage favored raising salaries for male sex-typed jobs, but favored alternatives to salary increases for female sex-typed jobs at entry and middle levels. Findings are discussed in terms of occupational sex stereotypes and differing perceptions regarding the urgency and difficulty of filling vacancies in male and female positions.Portions of this study were presented at the National Academy of Management Meetings, Chicago, 1986. 相似文献

The relationship of self-concept (self-esteem and mastery) and social support to psychological distress was studied among 68 Israeli women immediately prior to undergoing biopsy for suspected cancer (acute stress) and 3 months later for the noncancer group (everyday stress). It was predicted that women with stronger self-concepts and more social support would experience less state depression and state anxiety during the acute crisis than women with weaker self-concepts and less social support. It was further predicted that self-concept would be more critical than social support due to the acute nature of the event. Finally, self-concept was predicted to be related to psychological distress both during the acute and everyday stress situations (a direct effect), while social support was predicted to be related to psychological distress only during the acute stress situation (a buffering effect). The hypotheses were generally confirmed. However, self-concept and social support were seen as complexly related to psychological distress during the acute phase, one not necessarily being more critical than the other. The selective employment of available resistance resources to fit the situation and implications for preventive intervention were discussed. 相似文献

This experiment, with 167 introductory psychology subjects, successfully replicated and extended to a wider array of affective,
evaluative, and cognitive reactions, previous research on how would-be helpers cope when their help is rejected. It again
supported the thesis that violation of perceived expectancy of acceptance mediates the effects of rejection. Using an individual
difference measure of generalized self-perceptions of being a person who is sufficientlyefficacious and caring (acronym, EFCA) to help others, we found support for the predictions that high EFCAs would react more strongly than low EFCAs
on “proximal” forms of coping, but relatively less strongly on “confrontational” (future-oriented) forms. Our rationale was
that high EFCAs expect more acceptance, are more optimistic, and have greater self-investment in the outcome. Mixed support
was obtained for the prediction that situational differences in prior expectancy of acceptance moderate the effects of rejection.
Portions of the research were presented by the first author at the 98th Annual Convention of the American Psychological Association,
Boston, August 1990. 相似文献

Physics says that it cannot deal with the mind-brain problem, because it does not deal in subjectivities, and mind is subjective. However, biologists (among others) still claim to seek a material basis for subjective mental processes, which would thereby render them objective. Something is clearly wrong here. I claim that what is wrong is the adoption of too narrow a view of what constitutes ‘objectivity’, especially in identifying it with what a ‘machine’ can do. I approach the problem in the light of two cognate circumstances: (a) the ‘measurement problem’ in quantum physics, and (b) the objectivity of standard mathematics, even though most of it is beyond the reach of ‘machines’. I argue that the only resolution to such problems is in the recognition that closed loops of causation are ‘objective’; i.e. legitimate objects of scientific scrutiny. These are explicitly forbidden in any machine or mechanism. A material system which contains such loops is called ‘complex’. Such complex systems thus must possess nonsimulable models; i.e. models which contain impredicativities or ‘self-references’ which cannot be removed, or faithfully mapped into a single coherent syntactic time-frame. I consider a few of the consequences of the above, in the context of thus redrawing the boundary between subject and object. 相似文献

A self-fulfilling prophecy (SFP) occurs when the expectation of an event induces the behavior that increases the likelihood of the event's occurrence. Work organizations can be more or less effective as a result of SFP effects, whether naturally-occurring or deliberately induced by managers or consultants. Evidence for SFP at the individual level and at the collective level in work organizations is reviewed, including the Pygmalion, Galatea, Golem, and Messiah effects. Next, the SFP concept is extended beyond the single organization to the industrialization process at the national level. This leads to the novel hypothesis that, to the extent that persons in a developing nation expect industrialization to progress rapidly and successfully, the development process is facilitated. Several examples of SFP on Israel's path to industrialization are described, and emulation of these examples by other newly industrialized countries is proposed. 相似文献
