Attributions in marriage: review and critique 总被引:8,自引:0,他引:8
The prevailing behavioral account of marriage must be expanded to include covert processes. This article therefore examines the attributions or explanations that spouses make for marital events. A review indicates that dissatisfied spouses, compared with satisfied spouses, make attributions for the partner's behavior that cast it in a negative light. Experimental, clinical outcome, and longitudinal data suggest further that attributions may influence marital satisfaction. Rival hypotheses for these findings are examined. Because continued empirical development in this domain depends on conceptual progress, a framework is presented that integrates attributions, behavior, and marital satisfaction. This framework points to several topics that require systematic study, and specific hypotheses are offered for research on these topics. It is concluded that the promising start made toward understanding marital attributions holds considerable potential for enriching behavioral conceptions of marriage. 相似文献

The effects of Type A behavior and hardiness on depression and physical symptoms in the face of hassles were examined in 107 Japanese female college students. Analysis of variance indicated that Type A females had less depression under low hassles. There were no hardiness main effects or interactions. Neither Type A behavior nor hardiness moderated the adverse effect of hassles for Japanese women. An implication for research is suggested. 相似文献

Benefits of humor in reduction of threat-induced anxiety 总被引:2,自引:0,他引:2
The benefits of humor in reducing anxiety were investigated in a laboratory study, in which subjects were falsely led to believe that they would receive a shock in 12 min. Participants were 53 undergraduate students with either high or low sense of humor as measured by the Situational Humor Response Questionnaire of Martin and Lefcourt (1984). During the anticipatory period, subjects listened to either a humorous tape, a nonhumorous tape, or no tape. Dependent variables were repeated measures of self-reported anxiety, heart rate, and zygomatic facial activity. Anxiety increased over the anticipatory period, as predicted. A significant interaction between condition and time indicated that subjects from the humor condition consistently rated themselves as less anxious and reported less increase in stress as the shock approached. A three-way interaction concentrating on the final 3 min. indicated a tendency for subjects with low sense of humor to have higher heart rates in the no-tape condition than in the humorous or nonhumorous tape conditions. Analysis for zygomatic activity indicated more smiling by subjects with high sense of humor and by subjects in the humor condition. Also, the humorous tape elicited more smiling by subjects with high sense of humor. 相似文献

Ratings during acute and follow-up care by 35 families having members with traumatic brain injury showed none of the medical facilities met families' needs though some aspects of patients' care were rated higher in hospitals. Findings suggest comprehensive surveys are needed. 相似文献

This study replicated the results of an earlier one in which college women showing psychological similarities to anorexics indicated an unrealistically larger body-image relative to controls but only if they were relatively thin. This kind of perceptual enhancement was not found when inanimate objects were rated. The proposal that an enhanced body image plays a dynamic role in motivating food restraint (and may increase the risk of becoming anorexic) was supported by an analysis of dieting strategies. 相似文献

A comprehensive, multidimensional scale measuring job satisfaction was constructed for use in a major project concerned with personnel recruitment and retention of health professionals. 11 dimensions relating to opinions of immediate supervisors, physical working conditions, satisfaction with coworkers and with pay, aspects related to promotion and work motivation, are identified. These dimensions are shown to distinguish among health professionals on sex and between locations and different occupations. The scale also has high internal validity, producing a multiple R of .78 with over-all job satisfaction. 相似文献

R N Shepard 《Psychological review》1990,97(4):579-580
The neural net model of Staddon and Reid (1990) explains exponential and Gaussian generalization gradients in the same way as the diffusion model of Shepard (1958). The "cognitive" generalization theory of Shepard (1987), which also has been implemented as a connectionist network, goes beyond both of these models in accounting for classification learning. 相似文献

Scale invariance is a property shared by many covariance structure models employed in practice. An example is provided by the well-known LISREL model subject only to classical normalizations and zero constraints on the parameters. It is shown that scale invariance implies that the estimated covariannce matrix must satisfy certain equations, and the nature of these equations depends on the fitting function used. In this context, the paper considers two classes of fitting functions: weighted least squares and the class of functions proposed by Swain.Constructive comments by the referees are greatly appreciated. The author gratefully acknowledges Michael Browne's interest in his work. 相似文献
