The idea of a psychopathology of fate or what had come to be called a fate neurosis has failed to retain any established place in the structure of psychoanalytic thought. The clinical observations and theoretical formulations, to which the idea of a fate neurosis answered, have been subsumed in the course of things by more fundamental and systematic conceptualizations. A review of Helene Deutsch's (1930) paper, "Hysterical Fate Neurosis," is therefore bound to be largely an excursion into an area of intellectual history. However, such history never fails to shed light on certain ongoing clinical and theoretical problems that may have lost too much to current developments in psychoanalytic thought. It is with this historical purpose that the present study of Deutsch's classic paper on a fate neurosis is undertaken.  相似文献

This paper proposes test statistics based on the likelihood ratio principle for testing equality of proportions in correlated data with additional incomplete samples. Powers of these tests are compared through Monte Carlo simulation with those of tests proposed recently by Ekbohm (based on an unbiased estimator) and Campbell (based on a Pearson-Chi-squared type statistic). Even though tests based on the maximum likelihood principle are theoretically expected to be superior to others, at least asymptotically, results from our simulations show that the gain in power could only be slight.  相似文献

The effects of tobacco smoking on responses to electrical stimulation were studied according to a Method of Limits (ML) threshold analysis and a Sensory Decision Theory (SDT) analysis. For the ML procedure, Detection Threshold (DT), Pain Threshold (PT) and Tolerance Level (TL) measures were obtained. For the SDT procedure, nonparametric estimates of capacity to discriminate between stimulus intensities (P(A)) and response criterion (B) were calculated. There was no main effect of tobacco smoking on responses to electrical stimulation. Males had consistently higher ML thresholds than females in both the NS and S condition. Males also tended to increase in DT and PT after smoking. From a comparison between the effects of smoking on ML and SDT measures it was suggested that PT is related mainly to sensory factors and TL to response factors.  相似文献

The paper contains a detailed study of the St. Pauls' riots of April 1980. Particular attention is paid to the limits of participation in the event and the limits of crowd action. It is argued that these limits show clear social form and cannot be explained in terms of the individualistic theories that dominate crowd psychology. Instead a model of crowd behaviour based on the social identity model is advanced to account for the observations. It is concluded that crowd behaviour is more sophisticated and creative than hitherto allowed and that the neglect of this field should be remedied.  相似文献

Research into self-regulation and partner regulation strategies has largely involved parallel lines of research, thus, it is difficult to determine the relative contribution of both forms of regulation when it comes to relationship outcomes. Therefore, the question remains as to which form of regulation is more strongly associated with relationship quality; is it more important to focus on adaptive self-regulation or adaptive strategies to regulate one's partner? The current research addresses this important gap by comparing the relative associations of adaptive self-regulation and adaptive partner regulation strategies on romantic relationship quality. A community sample of mixed gender couples (N = 114) who were predominantly satisfied with their current relationships – but nonetheless still experienced relationship conflict – were administered self-report assessments of various self-regulation and partner regulation strategies as well as a measure of relationship quality. Couples also participated in a videotaped discussion of an unresolved relationship issue that was scored by trained coders for verbal and nonverbal indicators of self-regulation and partner regulation strategies. Actor–partner interdependence modeling revealed that for both men and women, adaptive self-regulation strategies were positively associated with their own evaluations of relationship quality as well as their partner's relationship quality. In contrast, engaging in adaptive partner regulation strategies was not significantly associated with men's or women's own, or their partner's relationship quality. Findings highlight the importance of focusing on self-regulation in relationships, as it is these strategies, over partner regulation strategies, that have more positive implications for the relationship quality experienced by typically satisfied couples.  相似文献
