Attributional models of depression suggest that depression is associated with internal, stable, and global causal explanations of events. However, the models do not specify whether the depressive attributional process involves the selection of certain causes, the assignment of dimensional meanings to those causes, or both. A distinction between these two processes was suggested by the findings that the choice of causes does not reliably indicate the perceived dimensions and that there is poor convergence between existing methods that assess causes and those that assess dimensions. When causes and dimensions were each measured in a manner that avoided confounding by the other, each made a unique contribution to the prediction of depression scores. Cause ratings alone were significantly associated with depression scores, but the optimal prediction of depression included both causes and dimensions. The implications of the distinction between these two processes for experimental manipulations of attributions and for reattribution training programs are discussed.  相似文献

Revision of the self-monitoring scale   总被引:14,自引:0,他引:14  
Snyder's (1974) Self-Monitoring Scale exhibits a stable factor structure that does not correspond to the five-component theoretical structure he presents. Sets of face-valid items that better approximate the theoretical structure are described. Correlations between these sets of items and measures of other constructs reveal that four of the five components are positively related to social anxiety. Effective social interaction is supposedly the high self-monitor's forte, and social anxiety appears to be incompatible with this. The correlational results therefore question the entire theory and indicate the need for a narrower definition of the construct. Adopting such a definition from Snyder's review article (1979), we present a 13-item Revised Self-Monitoring scale which measures only sensitivity to the expressive behavior of others and ability to modify self-presentation. A 20-item Concern for Appropriateness scale is also described. This scale measures 2 variables that are directly associated with social anxiety--cross-situational variability and attention to social comparison information. Both scales have acceptable internal consistency, and both yield 2 subscale scores as well as a total score. Prospective users of either scale are advised to treat the 3 scores separately.  相似文献

This paper explores a technical procedure, that of asking for one more response after the patient has given response(s) to Card X of the Rorschach. This "one last response" in the context of "ending" is discussed. Endings have many meanings but the ending of the Rorschach can be more than just a relief to the weary patient and/or tester who may have been experiencing the disquieting inner workings of the patient's unconscious. The ending of the Rorschach with the additional "one last response" can be the source of valuable clinical questions and inferences applicable to treatment.  相似文献

This article is intended to provide counselors with an overview of narcissism and its treatment. In the first section, dysfunctional narcissism is described, drawing on the diagnostic indicators presented in the DSM-III and the contemporary object relations theories of Heinz Kohut and Otto Kernberg. The second section focuses on counseling narcissistic clients.  相似文献

This study examined social skills components that precede the delivery of a skilled overt interpersonal response. Using a cognitive-behavioral systems approach to assertiveness, a task analysis of how women receive and process information in interpersonal situations requiring an assertive response to men was performed. Forty women were assigned to high- or low-assertive groups based on their Rathus Assertiveness Schedule scores. In small group sessions, each woman viewed four videotaped problem situations requiring an assertive response to both pleasant and angry males. After viewing each scene, each woman completed three questionnaires: (a) receiving information, (b) processing-generation of alternatives and decision making, and (c) processing-generation of consequences. High- and low-assertive participants were found to differ in their evaluation of consequences, for response options, particularly how a male would likely to behave to them. High-assertive participants were judged to evaluate more correctly than low-assertive participants the likely behavior of males if response options were implemented. All participants generated more complex alternatives and more assertive responses to situations involving an angry male as compared to a pleasant male. No differences were found between groups in their ability to receive information accurately. Correlational results were supportive of a cognitive-behavioral systems approach of assertion, that is, the emission of a skilled response depends on a chain of preceding responses.Thanks are due to Vida Dyson and Lenard Jason for their comments on an early draft of this paper.  相似文献

Twenty-two people who were presidential assassins and other similarly dangerous persons were assessed from information contained in Secret Service files and in published accounts. These documents were studied in order to determine common characteristics as well as other clues to the identification of potentially dangerous persons. Although there was no single pattern of development, there was a pattern of maladjustment that embraced common feelings of inadequacy or persecution, which led to similar patterns of behavior when attempting to resolve frustration. In practical terms, these profiles show:
  • 1 A systematic pattern of inadequacy in dealing with social, intellectual, and vocational challenges.
  • 2 A corresponding absence of any positive channel for achieving satisfaction or a sense of accomplishment.
In uniquely personal ways, each of these chronically frustrated individuals came to view his or her target either as the personification of the oppressive system, or as the agent through whom he or she could achieve “one great act,” or otherwise gain instant attention and status.  相似文献

Postpartum and lactational estrus: a comparative analysis in rodentia   总被引:1,自引:0,他引:1  
Virgin rodents exhibiting cycling estrus have traditionally been used for comparative studies of reproductive behavior. However estrus occurs in other life-history contexts, some of which differ from cycling estrus (CE) in that (a) the female is disposed to behave both maternally and sexually and (b) they result in litter overlap (i.e., the simultaneous gestation and lactation of two litters). In this report, two of these other modes of estrus are examined, with emphasis on their evolutionary and ecological implications. By means of a literature search of the order Rodentia, postpartum estrus (PPE) and lactational estrus (LE) were documented in 15 families, 71 genera, and 141 species. Analysis of these data showed that PPE and LE were nonrandomly distributed across taxa. They were statistically overrepresented in the family Cricetidae and underrepresented in squirrels (Sciuridae) and in pocket mice and kangaroo rats (Heteromyidae). Analysis of the phenotypes by which PPE and LE are achieved suggests important differences between them and CE in several parameters of female reproductive effort and breeding strategy, including maternal and copulatory behavior, optimal timing of litters, and hormonal control of heat and lactation.  相似文献

Analysis of two chimpanzees' conversations with their teacher during a tool-use training task demonstrated that chimps use lexigrams, a humanly devised visual symbol system, selectively to encode perceived variability; that is, they generally used their symbols to differentiate alternative possibilities or to represent change or novelty in a situation. In contrast, they tended to leave unsaid what was unchanging, repetitive, or the unique possibility in a situation. Perceived variability influenced not only which symbols were selected but also utterance length: A single dimension of variability in a situation leads to single-lexigram utterances; multiple dimensions are associated with multi-lexigram utterances. This pattern of results indicates that the absence of formal grammatical structure in chimp language does not imply that utterances beyond one word in length are either rote strings or imitations. The chimps' tendency to mention the variable while leaving the constant or redundant unsaid is, moreover, strong support for the position that their use of a humanly devised symbol system is more than a series of conditioned responses.  相似文献
