We examined the amenability of abstractions of categories to new and relevant information. In Experiment 1, Ss formed impressions of 2 sets of numbers by periodically estimating the cumulative means of each set. During the 1st half of the procedure, the 2 means were mathematically stable. During the 2nd half of the procedure, the mean of 1 set was modified and the mean of the other set remained unchanged. We predicted and found that the resultant estimates for the modified category changed more when the mean difference between the 2 categories was enhanced than when it was reduced. Experiment 2 suggested that the accentuation effect results from a 2-stage process of category learning (Stage 1) and category change (Stage 2). Experiment 3 replicated the effect with person categories. The relevance of category accentuation is discussed with respect to the modifiability of social beliefs. 相似文献

Two studies examined the causal role of emotional arousal in self-evaluation maintenance processes. In previous work, Tesser and Campbell (1982) found that Ss were most charitable in their perception of another's performance when self-relevance was low and the other was close. If emotional arousal mediated this pattern of behavior, then the pattern of behavior should be replicated when arousal is present but attenuated when arousal is misattributed or low. The misattribution hypothesis was tested in Study 1. Study 2 was a correlational study in which physiological arousal and misattribution were measured. The results supported the prediction that SEM processes would be attenuated when arousal was attributed to external sources. The misattribution effect was particularly pronounced among more highly aroused Ss. The results are discussed in terms of their implications for the SEM model and person perception. 相似文献

People report excessive, unwanted social interactions, insufficient privacy, and are observed to be more socially withdrawn under crowded living conditions. If people socially withdraw from one another as a way to cope with crowding, this could lead to an unintended side effect of breakdowns in socially supportive relationships. A breakdown in socially supportive relationships could, in turn, account for some of the pathological consequences of chronic, high density living conditions. An empirical study of 175 male heads of household among inner city residents in India suggests that the adverse effects of residential crowding on psychological health are mediated by a breakdown of social support systems. The study also points to the value of examining social support as an endogenous variable in the stress and health process. 相似文献

Relation of sympathy and personal distress to prosocial behavior: a multimethod study 总被引:7,自引:0,他引:7

Assessed sympathy and personal distress with facial and physiological indexes (heart rate) as well as self-report indexes and examined the relations of these various indexes to prosocial behavior for children and adults in an easy escape condition. Heart rate deceleration during exposure to the needy others was associated with increased willingness to help. In addition, adults' reports of sympathy, as well as facial sadness and concerned attention, were positively related to their intention to assist. For children, there was some indication that report of positive affect and facial distress were negatively related to prosocial intentions and behavior, whereas facial concern was positively related to the indexes of prosocial behavior. These findings are interpreted as providing additional, convergent support for the notion that sympathy and personal distress are differentially related to prosocial behavior. 相似文献

Previous studies have demonstrated that effortful attempts to secure positive outcomes or avoid negative outcomes produce significant increases in systolic blood pressure (SBP), diastolic blood pressure (DBP), and heart rate (HR). Although these effects of active coping on cardiovascular reactivity are central in current psychosomatic theories, virtually all of the research to date has used impersonal, asocial tasks. Our two studies examined the cardiovascular effects of effortful attempts to influence other people. In Study 1, male subjects attempting to influence the opinions of their discussion partner to improve their own chances of winning money displayed significantly greater SBP, DBP, and HR reactivity. In Study 2, we obtained similar effects on SBP and DBP reactivity in men and women, while both preparing an influence attempt and making that attempt. Furthermore, reactivity levels were larger as the magnitude of incentive for successful persuasion increased. Implications of this interpersonal equivalent of active coping for the development of cardiovascular disease are discussed. 相似文献

Analyzed data from 154 school-age children and their mothers to examine the relations between stress, perceived competence and contingency, and behavior symptoms. Analyses focused on the relative merits of unidimensional vs multidimensional measures of control in predicting symptoms. The stress of undesirable life events and behavior symptoms were related in the expected direction. Multiple regression models with R2 ranging from .11 to .14 (all ps less than .0002) included significant main effects for stress, competence, and control. Analyses supported the relative superiority of the multidimensional measure of control. Models containing main effects and interaction terms were of equivalent magnitudes in accounting for variance in symptom scores. Findings support the idea of perceived control as a moderator of the stress-illness relation and are consistent with earlier suggestions that simple main effects models may be the most useful in examining these relations. 相似文献

Analyzed explanatory style across the life span. 30 Ss whose average age was 72 responded to questions about their current life and provided diaries or letters written in their youth, an average of 52 years earlier. A blind content analysis of explanatory style derived from these 2 sources revealed that explanatory style for negative events was stable throughout adult life (r = .54, p less than .002). In contrast, there appeared to be no stability of explanatory style for positive events between the same 2 time periods. These results suggest that explanatory style for negative events may persist across the life span and may constitute an enduring risk factor for depression, low achievement, and physical illness. 相似文献

Relations between anger expression and cardiovascular reactivity: reconciling inconsistent findings through a matching hypothesis 总被引:7,自引:0,他引:7

Previous psychophysiological research has demonstrated that both anger expression and anger suppression are related to cardiovascular responses, but in an inconsistent fashion. The present study tested the following hypotheses: (a) that the influence of anger expression style on psychophysiological responses would be limited to Ss exposed to an anger instigation, and (b) that the specific pattern of psychophysiological responses would vary as a function of whether Ss were induced to use their preferred vs. nonpreferred mode of anger expression style in response to the instigation. Seventy-eight male college undergraduates were randomly assigned to work on a task with either an annoying or a pleasant confederate and subsequently to write either a negative or a positive evaluation of the confederate. Blood pressure was measured intermittently and heart rate continuously throughout task performance and a subsequent 15-min rest period. Ss' preferred method of anger expression had been previously assessed by a self-report questionnaire. Systolic blood pressure results generally were consistent with the hypotheses. Implications of the findings for the etiology of cardiovascular diseases are discussed. 相似文献

We investigated the sensitivity of the Bender (1938) Visual-Motor Gestalt Test (BGT) using the Halstead-Reitan Neuropsychological Battery (HRB) as the criterion for cortical dysfunction. We studied 95 subjects over age 55 who had been diagnosed as having dementia or pseudodementia. Subjects were classified as mild, moderately, or severely impaired on the HRB and as impaired or unimpaired on the BGT. The results indicated that the BGT is less sensitive (36%) than was expected when used on an impaired geriatric population. The data further indicated that false negatives occurred more frequently with the BGT when individuals had mild neuropsychological impairment. Less frequent misclassifications occurred as the severity of impairment on HRB indices increased. 相似文献
