The fleeting gleam of praise: cognitive processes underlying behavioral reactions to self-relevant feedback 总被引:1,自引:0,他引:1
W B Swann J G Hixon A Stein-Seroussi D T Gilbert 《Journal of personality and social psychology》1990,59(1):17-26
We propose that a preference for favorable social feedback (i.e., self-enhancement) requires only that feedback be characterized as favorable or unfavorable but that a preference for self-confirming feedback (i.e., self-verification) is based on a more elaborate set of cognitive operations that requires both the characterization of feedback and a subsequent comparison of that feedback to a representation of self stored in memory. Study 1 set the stage for testing this hypothesis by showing that depriving people of processing resources interfered with their tendency to access their self-conceptions. In Studies 2 and 3, participants who were deprived of resources preferred the favorable, self-enhancing evaluator, whereas control participants displayed a preference for the self-verifying evaluator, even if that evaluator was relatively unfavorable. 相似文献

The Cook and Medley (1954) Hostility (Ho) scale has been used in several important studies evaluating potential health consequences of hostility. A relative lack of compelling information about the construct validity of the Ho scale, however, has raised concerns about the appropriate interpretation of previous research. In this study, 60 married couples discussed a low conflict topic, a high conflict topic, and then a second low conflict topic. High Ho men responded to the high conflict topic with significant increases in self-reported anger and anxiety and overt hostile behavior, but low Ho men did not. Furthermore, compared to low Ho men, high Ho men blamed their wives more for their usual disagreements on the high conflict topic and saw their disagreement-engendering behavior as more intentional. Among women, Ho scores were weakly related only to overt hostile behavior. Finally, couples consisting of two low Ho persons displayed a uniquely agreeable interactional style. 相似文献

This study investigated whether social support was related to immune function among spouses of cancer patients. Effects of depression and negative life events were examined as potential mediators. Results showed evidence of greater immunocompetence on 2 of 3 dynamic measures: natural killer cytotoxicity and proliferation response to phytohemagglutinin among spouses who reported high levels of social support. All six components of social support assessed by the Social Provisions Scale (Cutrona & Russell, 1987) were strongly related to these indices of immune function. No evidence was found for mediation by either life events or depression. 相似文献

Body image or body images?: Comparative, multidimensional assessment among college students 总被引:2,自引:0,他引:2
A major criticism of research on body image concerns the dubious assumptions of the unidimensionality of the construct and the equivalence of body-image measures. Our study of 125 male and female college students compared multiple measurement methods within each of two modalities of body image: (a) perceptual (body-size estimation) and (b) attitudinal (body-image affect and cognition). Clinically relevant indices of psychological adjustment and eating disturbance were included. Results clearly supported the distinction between attitudinal and perceptual modalities of body image and indicated more convergent and discriminant validity for the former than for the latter. Whereas one method of assessing size-estimation accuracy and most body-image attitudes produced relationships with maladjustment, only attitudinal body image and perceptual, self-ideal discrepancy measures were significantly linked to eating disturbance. Relationships were generally more consistent for women than for men. Implications are discussed in the context of extant and future research on body image with clinical and nonclinical populations. 相似文献

Current methods for assessing the quality of internalized object representations have not provided a continuous variable that simultaneously includes both an accuracy and a maturity component. A modification of Blatt, Brooks, Brenneis, and Schimek's (1976) Concept of the Object on the Rorschach scale that would combine the two components by weighting the quality of each response according to its form level was proposed. Initial discriminant and convergent validity of this modification was checked through correlations and multiple regression analyses using behavioral, diagnostic, and demographic data from 84 adolescent inpatients as dependent variables. Results indicate the modified score was directly related to measures of peer relatedness, intelligence, psychological health, and reality testing, and indirectly related to measures of psychosis and hostile, unmanageable behavior. The results support the utility of the modification for providing a continuous score that assesses both developmental maturity and accuracy, the two dimensions on which the concept of object representation is based. 相似文献

The purpose of this study was to examine the relationship between learned resourcefulness and two common addictive behaviors, namely, drinking and smoking. Male and female college students (N = 175) completed the Self-Control Schedule (SCS), the Quantity-Frequency-Variability questionnaire, and a smoking history form. Learned resourcefulness was related to self-reported patterns of alcohol consumption; specifically, heavy drinking subjects were lower in learned resourcefulness than were light and moderate drinkers who, in turn, were lower in learned resourcefulness than were infrequent drinkers and abstainers. Learned resourcefulness was only modestly related to smoking, with students who had never smoked evidencing somewhat higher learned resourcefulness than ex-smokers and current smokers. Overall, these data provide correlational support for the notion that learned resourcefulness may protect young adults against substance abuse. 相似文献

Clerical people, returning to secular life, may undergo shifts in self-experience, including alterations in internal object relations. Self-psychology, positing the importance to health of cohesion of all aspects of self, provides a theoretical model for exploring such shifts and their facilitation through psychoanalytic psychotherapy. A case of a released Roman Catholic priest is discussed to illustrate dynamic processes. Emphasis is on a clinical approach that does not require conversion of religious and spiritual self-experience into drive derivative formulations 相似文献

Choice between delayed reinforcers and fixed-ratio schedules requiring forceful responding. 总被引:1,自引:1,他引:0 下载免费PDF全文
This experiment measured pigeons' choices between delayed reinforcers and fixed-ratio schedules in which a force of approximately 0.48 N was needed to operate the response key. In ratio-delay conditions, subjects chose between a fixed-ratio schedule and an adjusting delay. The delay was increased or decreased several times a session in order to estimate an indifference point--a delay duration at which the two alternatives were chosen about equally often. Each ratio-delay condition was followed by a delay-delay condition in which subjects chose between the adjusting delay and a variable-time schedule, with the components of this schedule selected to match the ratio completion times of the preceding ratio-delay condition. The adjusting delays at the indifference point were longer when the alternative was a fixed-ratio schedule than when it was a matched variable-time schedule, which indicated a preference for the matched variable-time schedules over the fixed-ratio schedules. This preference increased in a nonlinear manner with increasing ratio size. This nonlinearity was inconsistent with a theory that states that indifference points for both time and ratio schedules can be predicted by multiplying the choice response-reinforcer intervals of the two types of schedules by different multiplicative constants. Two other theories, which predict nonlinear increases in preference for the matched variable-time schedules, are discussed. 相似文献

Subjects lived in a laboratory apartment for up to 30 days, engaging in ordinary activities such as reading, sewing, and artwork. The amount of time devoted to each activity was recorded and compared with periodic verbal ratings of the amount of time devoted to the activities. The verbal and observational assessments of the time distribution were very similar, but there were some discrepancies. Based on self-reports and on observation of time actually devoted to the activities, contingencies were arranged in which time devoted to one activity produced time available for a second activity. When the contingency relation was based on behavioral assessment, predictions of time redistribution were more accurate than when the relations were based on verbal assessment. The close correspondence between observed distributions of time and verbally assessed distributions was probably due to the well-specified situation and rigorous assessment methods. Contrary to some cognitive-behavioral accounts, the contingency results suggest that verbal assessment is not necessarily preferable to observation when the two make discrepant predictions. It is suggested that verbal reports might be used more often in behavior analysis in place of lengthy or difficult observations, and attention is drawn to a personality model that parallels important components of behavior analysis. 相似文献
