This research tested the hypothesis that children's perceptions of academic competence and their personal control over school-related performance affects subsequent intrinsic interest and preference for challenge in an evaluative setting. In a correlational study, children's self-reported perceptions of academic competence and personal control were found to relate positively to their intrinsic interest in schoolwork and preference for challenging school activities. A subset of this sample was exposed to varying levels of a controlling directive, and preference for challenge was assessed behaviorally during a free-choice period in which subjects were unaware that they were being observed. As predicted, the data indicated that when given the evaluative, controlling directive, children who had high perceptions of academic competence and control preferred a greater challenge than did children whose perceptions were low on these measures. No difference between groups in terms of preference for challenge was evident when no controlling directive was presented. These findings are discussed in terms of theories of intrinsic motivation and potential processes that underly these effects. 相似文献

Personal vulnerability, life events, and depressive symptoms: a test of a specific interactional model 总被引:4,自引:0,他引:4
We tested Beck's (1983) hypothesis that depressive symptoms occur when an individual experiences a negative life event that specifically matches the individual's personal motivational vulnerability. Ninety-eight undergraduates completed measures of depression level, recent life events, and sociotropic and autonomous achievement motivations. Consistent with the theory, sociotropy was associated with depression level and also served as a moderator of the relations between depression and frequency of recent negative social events. However, sociotropy also demonstrated nonpredicted interactive effects with negative events categorized a priori as autonomy related. Autonomy was unrelated to depression and showed no evidence of being a vulnerability to any type of life event. The findings generally support the value of examining the role in depression of interactions between personality characteristics and life events, although they do not support the specific matching predictions. 相似文献

An experiment was conducted to examine the effects of medical diagnostic-test results on illness appraisal and the recall of symptoms and behavior. Subjects were tested for a fictitious enzyme deficiency and were told either that the test result was positive (deficiency present) or that it was negative (deficiency absent). In addition, some of the subjects were told the test was accurate 95% of the time and others were told it was accurate 75% of the time. As predicted, subjects judged the enzyme deficiency as less serious and more prevalent when presented with positive test results. Subjects with positive test results also recalled more behaviors that had been labeled as risk factors. Although positive test subjects tended to report more deficiency-related symptoms, diagnosis did not affect the free recall of general symptoms. In addition, information concerning the reliability of the diagnostic test had no effect on judgments or recall but did affect information seeking. Subjects with positive test results were less likely to request a definitive follow-up test when their results were unreliable. The results are interpreted as evidence for independent confirmatory search and denial processes following medical diagnosis. 相似文献

This study examined attitudes among 290 residents of three villages in South-West England toward proposals to build a nuclear power station nearby. Respondents were split into four groups according to whether they were neutral or in favor of a new power station either locally or elsewhere in the UK (Group PN), against one locally but neutral or pro elsewhere (LO), or moderately (MO) or extremely (XO) against a new power station both locally and elsewhere. The perceived impact of a nuclear power station on local life was assessed by 30 items. The PN group expected most benefit or least damage on all 30 items. On a majority of items the mean ratings of the LO group resembled those of the XO's more than did those of the MO's. A stepwise discriminant analysis yielded two interpretable functions. The first reflected a trend over the groups in the order PN-LO-MO-XO and was marked particularly by concern with impact on personal peace of mind. The second fuction discriminated the LO's from the other groups, suggesting that they were relatively less concerned with specifically nuclear risks, but more concerned with environmental conservation. 相似文献

Neuroticism, extraversion, and related traits in adult twins reared apart and reared together 总被引:3,自引:0,他引:3

The relative importance of genetic and environmental factors for neuroticism, extraversion, impulsivity, and monotony avoidance were estimated in a sample of 99 monozygotic and 229 dizygotic pairs of twins reared apart (TRA) and a matched sample of 160 monozygotic and 212 dizygotic pairs of twins reared together (TRT). The average age was 58.6 (SD = 13.6); 72% of the twins were 50 or older. Model-fitting analyses verified the importance of genetic factors for all four measures; from 23% to 45% of the total variation was attributable to genetic sources. There was considerable evidence that these factors were operating in a nonadditive manner for extraversion and impulsivity. Shared environment accounted for less than 10% of the variance; some evidence for selective placement was found for neuroticism. 相似文献

Council, Kirsch, and Hafner (1986) obtained empirical support for the hypothesis that significant correlations between questionnaire measures of absorption and hypnotic susceptibility are an artifact of subjects' beliefs about their own hypnotizability. We tested this hypothesis in a two-session experiment. During Session 1, subjects completed questionnaire measures of absorption, mystical experience, daydreaming frequency, and paranormal beliefs. During Session 2, subjects were tested for hypnotic susceptibility. Subjects were also exposed to one of three information manipulations: They were told about hypnotic testing either before or after filling out the questionnaires or were not told about hypnotic testing. The information manipulation moderated the prediction of susceptibility by the questionnaire measures for women, but not for men. For women, scores on the absorption questionnaire predicted susceptibility only when subjects were informed about hypnotic testing. In the told-after condition, this effect generalized to all of the remaining questionnaire measures. For men, none of the questionnaires was a reliable predictor of susceptibility. 相似文献

Traits and states are concepts that people use to both describe and understand themselves and others. We show that people view these concepts as prototype-based categories that have a graded internal structure and fuzzy boundaries and identify a set of attributes that define the prototypical cores of two categories: traits and states. Prototypical traits are stable, long-lasting, and internally caused. Prototypical states are temporary, brief, and caused by external circumstances. These prototypes are not defined by averages, as the family-resemblance principle would suggest, but by ideal (or extreme) attribute values. Like other ideal-based categories, traits and states serve particular goals. Trait concepts permit people to predict the present from the past; state concepts identify those behaviors that can be controlled by manipulating the situation. These two complementary schemas are part of the extensive theory of psychological causality that is implicit in language. Abstract social concepts differ from object categories in their category standards, the nature of their attributes, and the interrelations among those attributes. 相似文献

Personality in adulthood: a six-year longitudinal study of self-reports and spouse ratings on the NEO Personality Inventory 总被引:20,自引:0,他引:20
Previous longitudinal studies of personality in adulthood have been limited in the range of traits examined, have chiefly made use of self-reports, and have frequently included only men. In this study, self-reports (N = 983) and spouse ratings (N = 167) were gathered on the NEO Personality Inventory (Costa & McCrae, 1985b), which measures all five of the major dimensions of normal personality. Cross-sectional and longitudinal analyses on data from men and women aged 21 to 96 years showed evidence of small declines in Activity, Positive Emotions, and openness to Actions that might be attributed to maturation, but none of these effects was replicated in sequential analyses. The 20 other scales examined showed no consistent pattern of maturational effects. In contrast, retest stability was quite high for all five dimensions in self-reports and for the three dimensions measured at both times in spouse ratings. Comparable levels of stability were seen for men and women and for younger and older subjects. The data support the position that personality is stable after age 30. 相似文献
