Twenty-eight boys and 28 girls at each of the Piagetian preoperational, concrete operational, and formal operational cognitive stages were given an interview focusing on their concepts of family. Half of each group were from intact families, and half were from divorced families. Interviews were scored for two structural aspects of the concept of family: conceptual level, and use of dimensions that structure the concept. The complexity of children's concepts was strongly related to cognitive stage and, to a lesser degree, to sex. Frequency of use of concept dimensions was strongly affected by general developmental level, though not specifically cognitive stage, and by intactness of family, but to a lesser degree by sex. Specific information is provided on the effect of these factors on perceptions of family composition, parental roles, and breadth of family activities. 相似文献

In an attempt to replicate the findings reported in this Journal by Weyant and Smith (1987), members or recent donors to a Canadian civil liberties organization were asked to donate money under one of three conditions: (a) In the control condition, they were simply asked for a donation; (b) in the “smaller request” condition, they were asked to make a donation, but amounts of Canadian $30 to $100 were suggested; and (c) in the “larger request” condition, amounts of $50 to $250 were suggested. Unlike the Weyant and Smith studies, we found no difference in the proportion of respondents making a donation, but significant differences in the size of the donations made by those making donations. In our study, the most effective way of getting large donations was to ask for a large amount. It was suggested that the most likely explanations for the differences in the results of the two studies were the following: First, our target population were previous donors to the organization, whereas those in the Weyant and Smith studies were not likely to have been. Previous research suggests that those who had been donors previously are influenced, positively, by requests for a specific large donation, whereas those not previously approached are, if anything, negatively influenced. Second, our “larger request” appears to be within a plausible range for donations, whereas the larger request in the Weyant and Smith study may have been seen as being outside of the plausible range. In any case, however, we would recommend caution in drawing a conclusion about the most effective request size to encourage people to donate money to charity. 相似文献

During the 1970s various professionals and social activists adopted an explicitly anti-psychiatry position which was perceived by many as a new phenomenon. Hostility to psychiatry actually predates the establishment of psychiatry as a profession in 1844, and organized opposition to psychiatric practices appeared in the late nineteenth century. The deinstitutionalization of the 1970s, which was aided by development within psychiatry, had a strong anti-psychiatry component, but the novel aspect was the organization of ex-mental patients themselves. By the 1980s the decline of psychiatric power, dissension among ex-patients, and new social trends vitiated the anti-psychiatry movement. 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

The authors offer the Intraview©: Communication Intervention Strategy as a means of reducing high Communication Apprehension (CA). This intervention strategy, based on helping individuals to know more about themselves and their interactions with others, was implemented in a pretest, posttest, and control design, and CA was reduced at a statistically significant level (.01). 相似文献

The present study presents a new, unit-weight scoring system for the Depressive Experiences Questionnaire (DEQ). One hundred thirty-one college students completed the DEQ, the Bem Sex-Role Inventory (BSRI), and the Beck Depression Inventory (BDI). The revised DEQ scales were shown to have substantial levels of internal consistency. The three subscales of the revised DEQ were significantly correlated with the BSRI masculinity and femininity scales but not with gender. Significant correlations were also obtained between DEQ anaclitic, DEQ introjective scales and the BDI. 相似文献

Ethical considerations in the use of computers in psychological testing and assessment are discussed. Particular attention is given to existing ethics and standards that provide guidance to users of computerized test interpretation and report-writing programs. Issues covering professional accountability and confidentiality are also discussed as they relate to computer-assisted assessment. Areas of appropriate use of computers in testing and assessment are suggested, including test scoring, the analysis of scores, and generating remedial recommendations. Findings are summarized and several guidelines are suggested for users of computers in testing and assessment. 相似文献
