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

The family is a fundamental learning environment for many basic skills such as the ability to solve everyday domestic problems. A lack of competence in this type of problem solving would expose the individual to more frustration and possibly create the conditions for greater aggression. Forty-two low SES families, each including an aggressive boy, were invited to the laboratory for a problem-solving session on two occasions, at an interval of two years. Subjects were asked to find four preset combinations of colours by systematic permutations of four colours using a computer. Three types of cognitive performance were examined: resolution strategies, autoregulation strategies and the success rate in finding the solution. Results showed that most of the families were consistent in their use of a non-systematic strategy. Although some improvement in planning is observed during the second testing, no other improvement in autoregulation strategies was observed. In general, families had a better rate of success in finding the solution in the second session. The low cognitive level of these families and its stability are discussed. Étant donné que la famille constitue un terrain privilégié d'apprentissage, l'aggressivité comportementale de certains enfants pourrait résider dans le peu d'opportunités offertes par leur famille d'apprendre à affronter les problèmes de la vie quotidienne d'une manière réfléchie. Quarante-deux familles de milieu socio-économique faible, dont un des enfants est à risque d'inadaptation sociale et dont les parents sont peu scolarisés, ont à résoudre un problème nécessitant l'intelligence logique et ce, à deux ans d'intervalle (T-1 et T-2). La tâche consite à résoudre un problème de permutations à quatre éléments et se présente sous la forme d'un jeu d'ordinateur. Le fonctionnement cognitif est examiné selon trois dimensions: les stratégies cognitivcs de résolution, les stratégies d'autorégulation exercées, sur la démarche cognitive et l'issue de la démarche cognitive. L'examen des stratégies cognitives révèle que la majorité des familles utilisent une approche non stratégique et que cette approche est maintenue aussi bien à l'intérieur d'une séance donnée que d'une séance à l'autre. Exception faite de l'amélioration relevée à la séance 2 quant au contrôle exercé par les familles sur le déroulement de leur démarche cognitive, aucun changement n'émerge sur les autres critères de l'autorégulation. Finalement, les familles obtiennent une meilleure performance à la deuxième séance. La discussion porte sur la relative stabilité du niveau de fonctionnement cognitif des familles ainsi que sur la pauvreté apparente de leur répertoire de schèmes.  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 Depressive Experiences Questionnaire: revision and validation   总被引:3,自引:0,他引:3  
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
