To test the agreement between two observers who categorize a number of objects when the categories have not been specified in advance, Brennan & Light (1974) developed a statistic A′ and suggested a normal approximation for its distribution. In this paper it is shown that this approximation is inadequate particularly when one, or both, of the observers place a fairly equal number of objects in all of their categories. A chi-squared approximation to the distribution of A′ is developed and is shown to work well in a variety of situations. The relative powers of A′ and the ordinary X2 test for association are dependent on the type of ‘agreement between the observers’ that is assumed. However a simulation for a fairly general type of agreement indicates that the X2 test is more powerful. As the X2 test is also much easier to apply, it would seem preferable in most situations. 相似文献

This article considers what justification can be found for selecting randomly and in what circumstances it applies, including that of selecting patients to be treated by a scarce medical procedure. The author demonstrates that balancing the merits of fairness, common good, equal rights, and equal chance as they apply in various situations frequently leads to the conclusion that random selection may not be the most appropriate mode of selection. Broome acknowledges that, in the end, we may be forced to conclude that the only merit of random selection is the political one of guarding against partiality and oppression. 相似文献

One hundred and forty-four male and female Australian subjects rated an Australian or a Vietnamese target group on the possession of five socially desirable and five socially undesirable personality traits. As predicted, the out-group was perceived less favourably than the in-group, but only by the males, the females not making the distinction. 相似文献

The relative effectiveness of incentive and minimal justification techniques in promoting electrical energy conservation among 90 homeowners was investigated. Subjects in the Questionnaire condition were asked to complete a short energy conservation survey. Those in the Commitment condition were asked to curtail their consumption of electricity by 15%. In the Questionnaire + Commitment condition, subjects received both requests. These three groups were compared to an Incentive condition, where individuals were offered a highly attractive monetary incentive for conserving electricity, a Questionnaire + Commitment + Incentive condition, and a Control condition. The groups did not differ in electricity consumption during baseline, initial request, or follow-up periods. However, during the conservation period, homeowners in the Commitment and the combined treatment groups conserved more electricity and contained more conservers than either of the remaining groups. These outcomes were discussed in terms of the comparative effectiveness of minimal justification and incentive strategies for inducing behavioral change. 相似文献

The idealized physique preferences of a group of 94 male college students were measured and correlated with scales measuring attitudes toward women and personality rigidity. Three hypotheses, derived from sex-role research, were tested and confirmed: (1) Males who have negative attitudes toward women would like most to have a tapering V physique. (2) Males who have a rigid personality structure have stronger preference for an idealized muscular physique than males with more flexible personalities. (3) Males have a generally greater preference for a tapering V physique than women. It was concluded, from the results of this and other studies, that body preference is related to certain aspects of sex-role attitudes. 相似文献

Reports of learning from 119 participants of 18 general psychodynamic groups from the 1981 and 1982 annual meetings of the Canadian Group Psychotherapy Association were investigated. Two main learning factors emerged from a factor analysis of participant ratings, learning about oneself in a small group (factor one) and learning how to be an effective leader with professional skills (factor two). Participants reported moderate to considerable learning for both factors even though the stated task of the groups did not emphasize the learning of professional skills. Relationships between several classes of variables (group, leader, demographic) and reported learning were studied. Results that were consistent with several previous investigations were found. The discovery of a participant, sex-difference finding, i.e., greater reported learning by the women, generated a number of questions that may be addressed in future investigations.This article was derived from a paper presented at the Fourth Annual Meeting of the Canadian Group Psychotherapy Association, October 27, 1983, Banff, Canada. 相似文献

The present study examined the hypothesis that violation and role-playing instructions are necessary conditions for facilitation
on Wason’s selection task and that facilitation due to memory cueing via thematic content is secondary. The results of a factorial
experiment employing these factors did not support the hypothesis. Memory cueing was indicated as the primary factor, but
violation instructions did increase the amount of facilitation observed. This interactive effect and the nature of facilitation
by memory cueing are briefly discussed. 相似文献
