This study examined the differential evaluation of male and female stimulus cues and the effect of subject's androgyny level on their evaluations. Male and female college students filled out the Bem Sex Role Inventory (1974) and responded to set of five in-basket tasks taken from the Rosen, Jerdee, and Prestwich (1975) study of male managers. Sex of subject, sex of stimulus cue in the in-basket tasks, and androgyny level were varied in a series of 2 X 2 X 3 analyses of variance. On some tasks, male and/or female subjects responded in a sex role stereotyped manner. There were no effects for androgyny level. The discussion focused on circumstances under which stereotyping occurs and implications of the study. 相似文献

Recent research suggests important age and sex differences in the sex-typing of children's vocational interests. The present study adds to this area by examining several dimensions of job choices in children of four age groups (early and late preschool, second and fourth grade). The 120 children interviewed were asked three fixed-choice questions regarding nine jobs, along with open-ended job choice items. Analysis of age effects on several predetermined dimensions showed that older children were more selective in personal job choice, especially in regard to jobs attributed to the opposite sex. Avoidance of choices associated with the other sex was stronger in boys, but other sex differences were dependent on mode of inquiry rather than on sex. Girls were less limited than boys in job interests when asked about specific jobs but expressed more restricted choices on open-ended items. Implications of these findings both for further research and educational practices are considered. 相似文献

Controllability and human stress: method, evidence and theory. 总被引:4,自引:0,他引:4
S M Miller 《Behaviour research and therapy》1979,17(4):287-304
Concepts are defined and evidence reviewed on whether control reduces stress in man. Individuals seem to prefer instrumental control over an aversive event, seem to prefer to administer it to themselves, and are less aroused when waiting for a controllable event. When groups without control have equal predictability, having control is still less arousing; as potential (but unexercised) control seems to be. The evidence also suggests that controllable events may hurt less. Methodological weaknesses and empirical gaps in these data are pointed out. These data are grossly inconsistent with Relevant Feedback theory and rather inconsistent with Information-seeking theory and Safety Signal theory. A Minimax hypothesis is proposed: When individuals control aversive events, they believe relief to be caused by a stable source—their own response. This belief entails that maximum future danger will be minimized. When they have no control, they believe relief to be less stable, which entails no guarantee that maximum future danger will be minimized. The data are largely consistent with the Minimax hypothesis and wholly consistent when Minimax is supplemented by the premise that aversive events hurt less when encountered against a background of relaxation. 相似文献

The present study evaluated the effects of live modeling, covert modeling, and rehearsal in unassertive psychiatric patients. Psychiatric patients scoring 19 or below on the Wolpe-Lazarus Assertiveness Scale were assigned to one of five conditions, with 10 subjects in each group: (1) Test-retest (no treatment). (2) Live modeling plus rehearsal. (3) Live modeling without rehearsal. (4) Covert modeling plus rehearsal, and (5) Covert modeling without rehearsal. All subjects were videotaped (pre- and post-test) while responding to eight interpersonal situations (four training scenes; four generalization scenes) requiring assertive responses. Pre- and post-test responses for all subjects were rated independently by judges on several verbal and non-verbal components of assertiveness. The results indicated that live modeling and covert modeling effected improvements in the assertive behavior of the patients, but that the two treatments were not differentially effective. Generally, the addition of rehearsal to live or covert modeling failed to enhance treatment. But on two measures, the covert modeling plus rehearsal condition was superior to the other treatments. There was evidence for transfer of treatment effects from training to generalization scenes. No differences were found among the groups on the Wolpe-Lazarus Assertiveness Scale and the Eysenck Personality Questionnaire. The results were discussed in light of prior findings with live and covert modeling procedures. 相似文献

It was shown that either enhanced or decreased avoidance responding by rats could be produced by the same response blocking procedure occurring after avoidance training. The particular result produced depended on (1) the duration of the blocking trial and (2) when during the retention interval the blocking trial occurred. Results were interpreted in terms of a memory reactivation explanation and implications for the therapeutic uses of extinction were discussed. 相似文献
