Previous research has shown that people make more derogatory attributions for the behavior of outgroup members than for the behavior of ingroup members. However, these results may be due merely to a cultural stereotype of the outgroup rather than to ethnocentrism (which would entail dislike for members of the outgroup). To examine the effect of ethnocentrism on attributions, irrespective of the cultural stereotype, and to examine whether people who differ in ethnocentrism also differ in their attributions for whites and blacks, high and low ethnocentric whites made attributions for the success and failure of black and white actors on a task which required an ability that was outside the scope of the cultural stereotype of blacks, i.e., ESP ability. Examination of these attributions revealed that the more ethnocentric the subjects were, the more they tended to give whites greater credit for success than blacks, and the more they tended to give whites less blame for failure than blacks. These results were discussed in terms of their implications for the persistence of prejudice and for the effects of motivations on attributions for the behavior of others. 相似文献

In this report, we examine tachistoscopic perception of lines in structured figures. Previous research has shown that perception of lines is facilitated when the lines occur as parts of coherent three-dimensional figures. Experiment 1 demonstrates that it is not necessary for the figure to be three-dimensional to obtain facilitation. Experiments 2 and 3 show that three-dimensionality is not sufficient either. What is important is that the target lines be structurally relevant to the figure. However, structural relevance of a target segment to the figure as perceived with unlimited viewing time is not perfectly correlated with perceptibility under tachistoscopic conditions; it appears that the targets which fall on the external contour of a figure may be facilitated even without a high degree of structural relevance. In view of this, we suggest a model in which perceivers use processing heuristics to direct processing to aspects of the input that are potentially important for determining the structure of the final figure, working primarily from the outside in. 相似文献

Using biographical data from what we call a focused sample of 36 elite women, the conjugal power structure of their parental families is examined to assess its impact upon the development of political women. The results revealed that the mothers of elite political women scored higher on indices of independence both within the family structure and outside the home than did the mothers of elite nonpolitical women. The fathers of the elite political women tended to show more respect and love for their wives than did the fathers of the elite nonpolitical women. The fathers of elite political women also tended to view their work as interesting and fun rather than as just a job. The elite political women were also less likely to have brothers, particularly older brothers, than the nonpolitical women. This finding suggests that female involvement in politics is not necessarily derived from cross-sex-role preferences. The study suggests that in terms of political socialization, the father's behavior and achievements are not as critical for his daughter as they are for his son. Their importance for the daughter must be filtered through the effect the father and his behavior have on the mother and the sex-role ideology held by the family. 相似文献

Four retarded adolescents, enrolled in a short-term residential treatment program, received behavioral job interview skills training. Although potentially employable, each was unable to present himself effectively in standard employment interviews. Treatment consisted of a series of behavioral group sessions using instructions, modeling and rehearsal procedures to increase, in multiple baseline fashion, such skills as the adolescents' ability to disclose positive information about their experience and background, convey interest in the position and direct relevant questions to an interviewer. Effectiveness of treatment for each client was assessed by: (1) Objective ratings of performance during individual, structured role-play job interviews following each treatment group; (2) objective ratings of pre- and posttraining performance during tape recorded in vivo generalization job interviews at a fast-food restaurant; and (3) global evaluations of pre- and posttraining in vivo generalization interviews made by experienced personnel interviewers unfamiliar with the nature of the treatment. The results indicated that potentially employable retarded citizens can be successfully taught appropriate job interview behavior using a small group behavioral procedure. The need for such techniques in community and rehabilitation centers for retarded citizens and other clinical populations is discussed. 相似文献

Three-month-old infants of depressed (n=16) and non-depressed mothers (n=16) were habituated to video clips of a female model reciting phrases while posing happy or sad facial/vocal expressions and dishabituated to the alternate expressions. Overall, infants of depressed mothers took longer to habituate the video clips compared to infants of non-depressed mothers, and those assigned to habituate the sad video clips displayed a novelty response or dishabituated to the happy expressions. These findings suggest that 3-month-old infants of depressed mothers discriminate sad from happy expressions, however, they do not appear to perceive sad expressions as novel. 相似文献

Studies addressing Black adolescents' social change strategies are nonexistent and might be associated with the absence of social change measures for Black adolescents. In an effort to begin addressing this concern, the 30-item Measure of Social Change for Adolescents (MOSC-A) was designed to measure Black adolescents' first- (i.e., within the system) and second- (outside of the system) order social change strategies. Factor analysis of responses that 226 Black adolescents gave to the MOSC-A revealed first- and second-order social change factors. Item response theory analyses revealed that 65% of the items on the former factor adequately discriminate across different trait levels, but those of the latter were less promising. Scaffolded on this study, future research might refine the MOSC-A's psychometric properties and improve its utility. 相似文献

Excessive pain during medical procedures, such as burn wound dressing changes, is a widespread medical problem and is especially challenging for children. This article describes the rationale behind virtual reality (VR) pain distraction, a new non-pharmacologic adjunctive analgesia, and gives a brief summary of empirical studies exploring whether VR reduces clinical procedural pain. Results indicate that patients using VR during painful medical procedures report large reductions in subjective pain. A neuroimaging study measuring the neural correlates of VR analgesia is described in detail. This functional magnetic resonance imaging pain study in healthy volunteers shows that the large drops in subjective pain ratings during VR are accompanied by large drops in pain-related brain activity. Together the clinical and laboratory studies provide converging evidence that VR distraction is a promising new non-pharmacologic pain control technique. 相似文献

The introduction of deep brain stimulation (DBS) as a treatment for medication-refractory essential tremor in the late 1980s revealed, for the first time, that "chronically" implanted brain hardware had the potential to modulate neurologic function with surprisingly low morbidity. Over time, the therapeutic promise of DBS has become evident in Parkinson's disease and dystonia. In some experienced centers, complex tremor disorders, such as posttraumatic Holmes tremor and the tremor of multiple sclerosis, are being increasingly targeted. More recently, other indications, including obsessive-compulsive disorder, Tourette's syndrome, major depression, and chronic pain, have been proposed. As the field has expanded, our knowledge about potential cognitive side effects of DBS has also expanded. This article reviews the current knowledge regarding the impact of stimulation of the subthalamic nucleus, globus pallidus internus, and ventralis intermedius nucleus of the thalamus on symptoms in essential tremor, Parkinson's disease, and dystonia. Also discussed are the emerging targets, what is known about the cognitive sequelae of DBS, and what has been learned about the complications and therapeutic failures. 相似文献
