Children aged 7, 10, and 14 were shown sets of photographs of human figures for each of which they made judgments of age or attractiveness. Randomly determined responses appeared under each set of photographs. Half the children were told the responses represented choices of parents and the other half that they represented choices of unfamiliar adults. After the opportunity to imitate, children were asked whom they thought they agreed with the most. Findings indicated only a small, borderline-significant effect for same-sex imitation, but a large, highly significant effect for reported agreement, particularly in the unfamiliar adult condition (p < .001). Discussion centered on two issues: (1) Same-sex effects appear strongest when the act of choosing between adults and the adults' gender are accentuated; and (2) differences between present and previous findings regarding same-sex effects for parents vs unfamiliar adults may relate to the ages of the children investigated. 相似文献

This study investigated the relationship between life stress and measures of anxiety, depression, and hostility as a function of subjects' arousal-seeking status. Results indicated significant relationships between negative life change and measures of both anxiety and hostility. These relationships, however, held only for subjects who were low on the arousal-seeking dimension. The results suggest that arousal-seeking status may serve as a moderator variable in determining the relationship between life stress and other variables. 相似文献

Retention of a poison-based aversion after a 3-yr. period by 8 vervet monkeys (Cercopithecus aethiops) was found. The color of the visual cue appeared to effect the retention of the aversion. 相似文献

In Experiment 1, pictures were presented to subjects two, five, or eight times, and subjects were asked to imagine each pciture two, five, or eight times. Subsequently, subjects estimated the number of times each picture had been presented. Their estimates of the frequency of these external events were influenced by imagination trials; this effect was greater for good imagers than for poor imagers. Experiment 2 involved a similar design in which subjects were asked either to imagine the same referent for a word or to imagine a different referent for a word on successive imagination trials. Consistency (same referent) did not increase the influence of imaginations on immediate judgments of external frequency. Thus, the results of Experiment 1 were attributed to the greater accuracy (as opposed to greater consistency) of good imagers' internal generations of the stimuli. Furthermore, variation (imagining different referents), like greater accuracy, increased the effects of imagination trials on immediate but not on delayed judgments of frequency. Possible mechanisms underlying these effects are discussed. In general, the two studies show that qualitative characteristics of completely covert generations influence their impact on estimates of the frequency of external events. 相似文献

Durkheim divided suicide into four social types; egoistic, anomic, fatalistic, and altruistic assigning the first two to modern, western society while relegating the last two to pre-industrial social orders. However, contemporary studies of female suicidal behavior and depression show that such women exhibit personality characteristics of low self-esteem, passivity, dependence and living vicariously for others which correspond to the behavioral indices of impersonalism, submissiveness, passivity, and obedience that produce the lack of individuation characteristic of Durkheim's altruistic/fatalistic suicide categories. On this basis, the author suggests that altruistic/fatalistic suicide may even in the modern world be relevant to the explanation of female suicidal behavior, a hypothesis which, if true, would support the contention that "men and women inhibit different social worlds." 相似文献

Writings in psychoanalytic theory and social science that discuss the basis of men's motive to dominate women are reviewed. Both men's fear and envy of women and men's tenuous masculine identity arise from the exclusive early mother-child tie. It is suggested that an important step in altering the development of the motive underlying male dominance would be to have men, as well as women, care for infants. The possibility of greater equality in the family and in the economy is discussed.This article represents a considerable expansion of the first part of a paper entitled Sex Role Development and Sex Discrimination: A Theoretical Perspective by Jean Stockard, Miriam M. Johnson, Joan Acker, and Marion Goldman, presented at the annual meetings of the American Sociological Association in San Francisco in 1975. We wish to thank Joan Acker and Marion Goldman for the earlier discussions we had with them which led to this article. 相似文献

Resolution thresholds at 0° (fovea), 20°, 40°, and 60° along the horizontal meridian of the temporal visual field revealed a characteristic degradation in visual resolution with increasing stimulus eccentricity. However, substantial individual differences were found, particularly at 40° and 60° of eccentricity. Dramatic improvements in peripheral visual resolution occurred over a period of 11 practice sessions, with the time course of practice effects increasing for greater visual field eccentricities. Improvements with practice reduced, but did not eliminate, individual differences. The present visual resolution findings are compared to previous studies of peripheral motion detection and increment thresholds. 相似文献

Current on-line assessment applications are limited to mimicking instruments designed for paper and pencil. The development of an instrument designed specifically for on-line technology is described. The instrument provides research data on treatment effectiveness, clinical information for treatment planning, and management information for resource allocation. 相似文献
