Twenty couples living together, 10 married and 10 unmarried, were given the Bem Sex-Role Inventory and a questionnaire on the performance of household responsibilities. Findings provided partial support for hypotheses relating more traditional sex roles, living arrangements, and division of household responsibilities. Results also indicated a greater variability in household responsibilities for unmarried males and for males and females who were not traditionally sex typed. The latter results support a model which was formulated relating changes in sex-role attitudes with changes in sex-related behavior. In this model, a period of uncertainty intervenes between the change in attitude and the change in related behavior. 相似文献

Normal rats showed faster learning of a serial negative patterning (NP) discrimination (X+, A+, X-->A-) than of a comparable feature negative (FN) discrimination (A+, X-->A-). This advantage was absent in rats with lesions of the amygdala central nucleus. Earlier data indicated that this brain lesion interferes with surprise-induced increases in attention specified by the Pearce-Hall model (J. M. Pearce & G. Hall, 1980). In the NP task, but not the FN task, omission of the reinforcer after X on X-->A- trials was surprising. A variation of the NP task (NPX), in which X was reinforced on both X+ and X-->A- trials, was learned more rapidly than the NP task. Lesioned rats were unimpaired in learning the NPX task. Evaluation of the lesion effects and the results of posttraining transfer tests suggested that the NP advantage involved attentional processes, whereas the NPX advantage was based on the acquisition of inhibitory control by aspects of excitation conditioned to X. 相似文献
