This paper suggests that aspects of paranoid character are structured around fantasies of magical and concrete connectedness to objects; these fantasies serve to avoid the terrors of object inconstancy. The authors describe how these fantasies are expressed in the psychoanalytic situation and explore their relation to common paranoid phenomena. The paranoid person must maintain these fantasies of connectedness at all cost or risk experiencing unbearable indifference between self and object. Paradoxically, the sacrifice of self and object boundaries inherent in these fantasies makes object constancy even more difficult to achieve because of the secondary defensive use of anger mobilized to protect the boundaries of the self. 相似文献

To study malevolent representations, earliest memories were reliably coded on scales of affect tone. Ss were diagnosed with borderline personality disorder: 31 without and 30 with concurrent major depression. Nonborderline comparison subjects had either major depressive disorder (n = 26) or no psychiatric diagnosis (n = 30). Borderline subjects were discriminated from comparison subjects by their more malevolent representations; they more frequently produced memories involving deliberate injury; and they portrayed potential helpers as less helpful. Results suggest the diagnostic significance of malevolent representations, which need to be explained by any theory of borderline personality disorder. 相似文献

Twenty depressed patients with major depressive disorder, 20 nondepressed matched control subjects, and 17 patients with anxiety disorders were compared in different measures of social problem solving. Problem solving was assessed with the Means-Ends Problem-Solving Test (Study 1), the solution of personal problems, and a problem-solving questionnaire (Study 2). Results showed that, as predicted, depressed subjects suffered from a deficit in problem solving in all three measures. The majority of these deficits were also displayed by the clinical control group rather than being specific to a diagnosis of depression. However, depressed subjects produced less effective solutions than did normal and clinical control subjects. The results suggest that depressed and anxious patients may have difficulties at different stages of the problem-solving process. 相似文献

To test Coyne's (1976b) theory of depression, students' levels of depressive symptoms, reassurance seeking, and self-esteem were assessed at Time 1, and their same-gender roommates' appraisals of them were assessed 5 weeks later. Mildly depressed students engaged in the type of reassurance seeking described by Coyne. Among men, but not women, mildly depressed students were rejected if they strongly sought reassurance and had low self-esteem but not if they did not seek reassurance or had high self-esteem. Although induction of depressed symptoms in roommates did occur, this contagion effect did not account for the depression-rejection relationship. The prediction that unsupportive, intolerant, or unempathic others would be particularly likely to respond with rejection to reassurance-seeking depressed students with low self-esteem received partial support. Implications for future work on the interpersonal aspects of depression are discussed. 相似文献

Effortful and automatic memory task performances were examined in 36 schizophrenic patients and 18 normal control Ss. Tasks included free recall, recognition, and frequency estimation. Patients demonstrated impairment in recall, in recognition, in semantic encoding, and in frequency estimation. Deficits were observed across tasks despite differences in attentional demands. The results suggest a basic compromise of memory function, which is consistent with recent neuroimaging evidence of structural or physiological abnormalities in frontal and temporal lobe structures in schizophrenia. 相似文献

Predictors and consequences of childhood depressive symptoms: a 5-year longitudinal study. 总被引:31,自引:0,他引:31
A 5-year longitudinal study investigated the interrelationships among children's experiences of depressive symptoms, negative life events, explanatory style, and helplessness behaviors in social and achievement situations. The results revealed that early in childhood, negative events, but not explanatory style, predicted depressive symptoms; later in childhood, a pessimistic explanatory style emerged as a significant predictor of depressive symptoms, alone and in conjunction with negative events. When children suffered periods of depression, their explanatory styles not only deteriorated but remained pessimistic even after their depression subsided, presumably putting them at risk for future episodes of depression. Some children seem repeatedly prone to depressive symptoms over periods of at least 2 years. Depressed children consistently showed helpless behaviors in social and achievement settings. 相似文献

The past fifteen years have seen the development of a considerable research literature on the social psychology of procedural justice (see Lind & Tyler, 1988, for a review). Procedural justice research reveals some serious shortcomings in the exchange theories that have traditionally dominated Western analyses of the social psychology of groups, and in so doing, the procedural justice literature has important ramifications for cross-cultural psychology. Results from a number of studies conducted in the United States and Western Europe show that individualistic, self-interest based models of human behaviour are insufficient to explain procedural justice phenomena. Instead, procedural justice effects frequently reveal strong group-oriented concerns and motivations even in cultural contexts generally thought to be characterized by individualistic orientations. The research literature also shows that if a group's procedures are judged to be fair, people are more likely to show group-oriented behaviour and to hold more favourable attitudes toward the group and its leaders. These findings have led to the development of a theory of justice judgments—the Lind and Tyler group-value theory—which is based on group norms and relations rather than on social exchange theory. We describe a general model of social behaviour that integrates group- and individually-oriented behaviour, and we discuss the implications of the model for social and cross-cultural psychology. 相似文献

When thinking under uncertainty, people often do not consider appropriately each of the relevant branches of a decision tree, as required by consequentialism. As a result they sometimes violate Savage's sure-thing principle. In the Prisoner's Dilemma game, for example, many subjects compete when they know that the opponent has competed and when they know that the opponent has cooperated, but cooperate when they do not know the opponent's response. Newcomb's Problem and Wason's selection task are also interpreted as manifestations of nonconsequential decision making and reasoning. The causes and implications of such behavior, and the notion of quasi-magical thinking, are discussed. 相似文献

In an article in the Journal of Applied Psychology, Vecchio (1990) purported to test cognitive resource theory (Fiedler, 1986; Fiedler & Garcia, 1987). We present evidence that Vecchio's article seriously misrepresented previous work on cognitive resource theory and also contained several flaws in methodology that call into question his conclusions regarding the validity of cognitive resource theory. 相似文献
