This study examined two separate, but potentially interactive, influences on depressive self-evaluation: social context and perceptions of task difficulty. First, it was hypothesized that, if negative self-evaluations of depressed individuals are motivated by a desire to elicit attention and sympathy from others, depressed subjects should evaluate themselves more negatively than nondepressed subjects in a public setting, but not when they make self-evaluative judgments in private. Second, it was hypothesized that negative self-evaluation results from a bias to perceive tasks as being intrinsically easy, i.e., if a task is easy, a given score would be evaluated more poorly than if the task were difficult. It was found that the self-evaluations of depressed subjects were influenced by the social context, but not always in a negative direction. Depressed subjects did not differ from nondepressed subjects when performance evaluations were made in private. In a public condition, depressed subjects evaluated themselves more negatively than nondepressed subjects following an easy task, but evaluated themselves more positively following a difficult task. Depressed subjects did not evidence a bias to perceive tasks as being intrinsically easy. Depressed subjects did rate the tasks to be more difficult for themselves than they thought they would be for others and this expectancy was predictive of negative self-evaluation. These results were discussed in terms of alternative self-presentation motives and theories of social cognition. Self-evaluation often involves social comparison and researchers need to attend to the potentially complex interactions among social and cognitive processes.I would like to thank Deborah Davis and Paul Westerholm for their help in data collection, Ruth Maki for her statistical expertise, and the anonymous reviewers for their thoughtful comments. Portions of this paper were presented at the Annual Convention of the American Psychological Association, New Orleans, 1989.  相似文献

Normative data (N=896) collected on solutions to the traditional reasoning problem “Brothers and sisters have I none,/That man’s father is my father’s son” was the platform for a set of experiments to investigate the roles of problem structure, subject strategy, and working memory in error making in a class of verbal problems. The normative data revealed that the modal, but incorrect response to the brothers and sisters problem was “himself,” whereas the correct response of “son” was given by only 17% of subjects for the traditional version above, rising to 40% for a reordered novel version. This problem’s structure, identified as adouble-modifier structure, was found to produce similar response patterns across a range of verbal problems. Results from (1) syntactical structure manipulations (e.g., “My father’s son is the father of that man”), and (2) efforts to teach subjects to use a linear strategy (a sequence of steps), interpreted within a framework of Just and Carpenter’s (1992) capacity theory of comprehension, suggested that working memory overload varies across within-structure modifications and subjects. Further-more, this overload may be compounded by subjects’ choices of strategy.  相似文献

Females tend to score lower than males on measures of computer aptitude and attitudes. This study examined the potential effects of several mediating factors, sex of experimenter, sex of experimental partner, sex typing (Bem Sex Role Inventory score), and level of past experience, on a computer interaction task involving a dyad. College students, drawn from a primarily white college population, after completing paper-and-pencil measures assessing computer experience, computer attitudes, and gender roles, participated in a computer task involving drawing up to ten prescribed geometric patterns on a computer screen. Research assistants recorded the number of correctly completed patterns and videotaped participant interaction through a one-way mirror. Males reported experiencing more computer involvement than females. For males, past computer experience and masculinity were correlated with more positive computer attitude scores. For females, only past computer experience related to more positive computer attitude scores. Analyses of the computer interaction variable indicated that participants asked male research assistants significantly more questions than female research assistants. Several interaction effects were also found.A previous version of this paper was presented at the annual meeting of the Southwestern Psychological Association, New Orleans, April 1991.  相似文献

The relationship between parental self-esteem and behavior problems in children was investigated using 1624 married couple's responses from the National Survey of Families and Households. The sample was weighted to be nationally representative in terms of race and ethnicity. It was hypothesized that the existence of behavior problems among children would be associated with low self-esteem among parents and that the parent's gender, child's gender, parents' gender role attitudes, and parental employment would moderate this relationship. The results indicated that parental self-esteem is negatively associated with behavior problems in children. However, none of the moderating variables had a significant impact. This suggests that the relationship between parental self-esteem and behavior problems among children is robust and does not vary appreciably with the gender of the parent, the gender of the child, the attitudes of the parent, or the employment of the parent.  相似文献

A series of experiments on intersensory facilitation demonstrates that non-informative sound of low to moderate intensity (30/80 dB) facilitates the reaction to a visual stimulus. By manipulating the preprocessing and perceptual stages of the visual signals, it appears that auditory intensity reduces choice reaction time independently from the positive influence of the intensity and duration of the visual imperative signal, but interacts with the effect of stimulus degradation. Degraded stimuli take more profit of the sound than intact stimuli. Besides a short-term activation effect, originated by accessories of the auditory modality, on the motor adjustment stage (cf. Sanders 1983), the results suggest that the accessory influences the stage of feature extraction.  相似文献

In the match/mismatch model, recently formulated by Rachman and coworkers, it is stated that incorrectly predicted aversive experiences are generally followed by an immediate adjustment of the predictions concerning aversiveness of the next experience. This model can be considered to reflect a psychological process of the formation of expectations. In the present article it is argued that a simple H0 model, assuming that predictions are completely randomly generated by the subject, may account for the same effects. This H0 model is used in a stringent test of empirical data to determine if there are any effects of the discrepancy between prediction and experience on next prediction that exceed the effects explained by the H0 model. Although the H0 model produces effects very similar to the empirically observed effects, there is clear support for the hypothesized influence of the discrepancy between prediction and experience. Therefore, the model appears to reflect 'real' psychological processes and not chance findings.  相似文献

Escape and avoidance that are disproportional to the danger of the pertinent stimulus are important clinical problems that are often related to inaccurate (catastrophic) expectations. One possible source of such expectations is a prior, underestimated aversive experience. In the present experiment the hypotheses that underestimated pain leads to escape and that it leads to avoidance were tested. In order to control for the effect of the intensity of the pain stimulus, a control group that received 20 pain stimuli of high intensity was formed. Subjects in the experimental condition received 17 pain stimuli of low intensity and 3 of (unexpectedly) high intensity (experimentally induced underprediction). Underprediction of the high intensity stimulus was significantly related to escape, but not to avoidance. The results suggest that the way in which avoidance was operationalized accounts for this. The strong support of the hypothesized relationship between underpredicted pain and escape is an important finding, however.  相似文献

This paper discusses the neuroanatomy and pathology of facial expression and findings on the neuroanatomical connections between expressions of the face and speech. The facial musculature is briefly dealt with in terms of its innervation by the facial nerve and its relationship to the soft palate at the peripheral system level. After considering the facial nuclei, the supranuclear innervation of volitional and emotional facial expression is reviewed. Then supranuclear relations between facial movements and some speech organs are considered. Finally, attention is paid to aspects of facial paralysis stemming from peripheral and central origins.  相似文献

Conclusion Given my dilemma, then, we should think twice before following Putnam away from metaphysical realism. Internal realism can offer only a false sense of philosophical security. And now we may doubt that it can offer even that.  相似文献
