The perception of control may be established if an individual is provided with an opportunity to choose and if the outcome of the choice is moderately uncertain. In turn, perceived control has been shown to enhance motivation and performance. In the present experiment, the effects of uncertainty about environmental control were examined by measuring the speed with which choices were made. When control was implicitly provided, decision latencies were shorter than when control was either explicitly available or not available at all. Paradoxically, providing information about control may reduce uncertainty and thereby diminish the perception of control. The contribution of control and choice to the development of perceived control is discussed.This research is based on a thesis by the first author submitted in partial fulfillment of the master of science degree at Virginia Polytechnic Institute and State University and was supported by a grant from the U.S. Army Research Office to the second author. 相似文献

Current research has suggested that musical stimuli are processed in the right hemisphere except in musicians, in whom there is an increased involvement of the left hemisphere. The present study hypothesized that the more musical training persons receive, the more they will rely on an analytic/left-hemispheric processing strategy. The subjects were 10 faculty and 10 student musicians, and 10 faculty and 10 student nonmusicians. All subjects listened to a series of melodies (some recurring and some not) and excerpts (some actual and some not) in one ear and, after a rest, to a different series of melodies in the other ear. The task was to identify recurring vs. nonrecurring melodies and actual vs. nonactual excerpts. For student musicians, there was a right-ear/left-hemispheric advantage for melody recognition, while for student nonmusicians, the situation was the reverse. Neither faculty group showed any ear preference. There were no significant differences for excerpt recognition. Two possible explanations of the faculty performance were discussed in terms of physical maturation and a functionally more integrated hemispheric approach to the task. 相似文献

This investigation examined the strategies employed by individuals when testing hypotheses about the self. Participants known to possess masculine, feminine, or androgynous sex role identities tested hypotheses about their suitability for one of two jobs: either a job characterized in terms of the attributes and aptitudes typically associated with a “masculine” personality, or one characterized in terms of those typically associated with a “feminine” personality. When testing these hypotheses about themselves, participants preferentially reported those aspects of themselves that would suggest their suitedness rather than their unsuitedness for the job under consideration regardless of their sex role identity. Moreover, subsequent judgments of job suitability were positively related to the amount of suitedness evidence reported, but unrelated to the amount of unsuitedness evidence reported. Some consequences of these strategies for testing hypotheses about the self are discussed. 相似文献

The influence of individuals on situations: Implications for understanding the links between personality and social behavior 总被引:2,自引:0,他引:2
Mark Snyder 《Journal of personality》1983,51(3):497-516
In an analysis of the nature and origins of predictability in social behavior, two propositions are considered: (1) There exist categories of individuals whose social behavior is readily predictable from measures of personal attributes such as attitudes, traits, and dispositions as well as categories of individuals whose social behavior is readily predictable from situational and interpersonal specifications of behavioral appropriateness; (2) underlying these differences in predictability are systematic choices to enter and to spend time in social settings and interpersonal contexts that promote and facilitate one or other of these characteristic behavioral orientations. The implications of these propositions for the study of personality and social behavior are considered in the specific case of the psychological construct of self-monitoring and in the general case of understanding the reciprocal influences of individuals and their social worlds. 相似文献

There has been considerable controversy about whether human behavior is consistent across situations and time. Using the adjective generation technique (AGT), Allen and Potkay (1973, 1977a) found that subjects' self-favorability was quite variable and concluded that this did not support Bem and Allen's (1974) position that the consistency would be greater if idiographic assessment techniques were utilized. Bem (1977) criticized this conclusion, making the points that the AGT is not idiographic and that the favorability value of each day should be considered as a single item in a larger test rather than be considered independently. The present study was designed to address both the consistency of behavior across time and also the controversy regarding the AGT. Eleven psychiatric inpatients completed the AGT for 30 consecutive days. The results indicated that while AGT values are highly variable on a day-to-day basis, these values are quite consistent when averaged across even short periods of time. These results are very similar to those reported by Epstein (1979). 相似文献

Duplex perception, a phenomenon previously demonstrated for speech stimuli, is demonstrated here for musical stimuli. In the first experiment, major and minor chords are produced by dichotic fusion of two simultaneous piano notes presented to one ear (perfect fifth) with a “natural” or “flat” single note presented to the opposite ear. Musically trained subjects perceive simultaneously both the single tone and a fused (major or minor) chord. The chords are labeled more consistently than the single notes, even though the fused chords differ solely in terms of the contralateral notes. In a second experiment, using pure tones in place of piano notes, other musically trained subjects individually exhibited categorical perception for either the fused chord or the single tones, but never for both types of stimuli. The duplex phenomenon is discussed in terms of its implications for its specific component modes of perception. 相似文献

Type A coronary-prone behaviour has been repeatedly associated with an increased incidence of coronary heart disease (CHD) amongst middle-aged men and women. This association appears to be independent of other standard CHD risk factors such as smoking, high blood pressure and elevated serum cholesterol levels. This paper presents normative and correlational data for a number of commonly-employed self-report measures of Type A behaviour and the structured interview. These data replicate U.S. findings that self-report measures tend to correlate only moderately with the Structured-Interview method of assessment of Type A behaviour. The implications of these data for researchers attempting to assess Type A behaviour, especially with limited resources, are discussed. 相似文献

An apparatus is described that automates the elicitation of the proboscis extension reflex (PER) in dipterans. The PER has been used as a measure of both classical conditioning and central excitation. Most studies of PER have employed manual stimulation, which adds inter- and intraexperimenter differences in technique as another source of variance. The advantages of this apparatus are (1) elimination of individual differences in manual techniques of experimenters as a possible source of error variance and (2) capability of stimulating several flies individually during a single session. An experiment is reported comparing the manual and automated methods. 相似文献

A sample of 112 administrators provided self-report data used to test two hypotheses derived from Korman's consistency model of work behavior. As predicted, those with high self-esteem experienced significantly greater need gratification than did those with low self-esteem, and self-esteem also significantly positively moderated the relationship between n gratification and work satisfaction. Need gratification was assessed for only those needs that were most salient for each person, thus eliminating a rival interpretation of the findings derived from the self-enhancement model of self-esteem. The moderating effect of self-esteem on the n gratification-work satisfaction relationship was limited to those experiencing low levels of n gratification, indicating a possible “boundary condition” of consistency theory. A problem with the use of moderator variables in behavioral science was also discussed. 相似文献
