Three groups of white children, 43 preschoolers and first-graders, 46 third-graders, and 44 fifth-graders, were asked to choose either a white child or a black child as a recipient of sharing and also as a companion for several social interaction situations ordered for social distance. The preschoolers and first-graders preferred to share and interact socially with the white child. The third-graders and the fifth-graders displayed a weaker preference for the white child over the black child on the sharing task, no preference in situations of high social distance, and a preference for the white child in situations of low social distance. The results from ancillary measures suggested that the choices of the younger children were motivated by a generalized color preference but that the choices of the older children were guided by an awareness of the social meaning of racial categories.The investigation was supported by the Research Advisory Council of East Tennessee State University.  相似文献

Auditory and visual stimulus-seeking behavior was measured in hyperactive and nonhyperactive youngsters. The design controlled for motor activity level. The results indicate that hyperactive children preferred auditory stimulation more than the control children. There were no differences in stimulus-seeking preferences in the visual modality. The groups did not differ in motor activity. It was concluded that abnormally high needs for stimulation are important in hyperactivity.The authors would like to express their appreciation to James Fogarty, Superintendent, Walter Galvin, Principal, and the many teachers, students, and parents of the Greene Avenue Learning Center of BOCES II in Sayville, New York for their cooperation and support in this study. We would also like to thank Susan O'Leary, Ph.D. Director of the Point of Woods Laboratory School and the students and parents for participation and support in this study.  相似文献

Rapid growth has been observed in recent years in the number of women entering traditionally male blue-collar occupations, yet researchers have paid little attention to this pioneering group. The present study undertook a comparison of the job conditions of two groups of nontraditional women workers, tradeswomen (N=71), and transit workers (N=151); a third group, school secretaries (N=389), was studied as a comparison group of traditionally female workers. Results from a 16-page mail questionnaire revealed that women in traditionally male occupations encountered significantly more adverse working conditions than did their traditional counterparts, and, in addition, reported significantly less satisfaction and more stress at work. Tradeswomen were the most likely to experience sexual harassment and sex discrimination, and black tradeswomen to experience race discrimination. The degree of job satisfaction expressed by the secretaries was unexpected, since most evidence suggests that clerical workers lack autonomy, and encounter boredom and routinization on the job. These findings are discussed in terms of gender segregation and the need to focus future research efforts on specific occupational groups in order to make appropriate policy recommendations as well as to provide help for women in these jobs.This research was supported by grants from the National Institute for Occupational Safety and Health (Grant No. 1 RO1 OH02162-01A1) and the College of Health and Human Development, The Pennsylvania State University.

When subjects must identify a barely visible line in a briefly flashed display, their accuracy depends on the configuration of the context in which the target line appears. Weisstein and Harris (1974) found that accuracy is highest when the target is part of a pattern that resembles a unified, three-dimensional object, and lowest in a flat-looking pattern composed of disconnected lines; they labeled this phenomenon the object-superiority effect. In the three experiments reported here, identification accuracy was found to correlate highly and significantly (r =.78) with the judged depth of the patterns. Judged structural relevance of the target line to the pattern (McClelland & Miller, 1979) was uncorrelated with accuracy (r=?.28). Even when the target line appeared as an isolated fragment within the context pattern, a pattern perceived as three-dimensional yielded higher identification accuracy than one perceived as flat.  相似文献

The Fishbein regression model (B ≈ BI ≈ (Aact)w0 + (NBs)w1) is designed to predict behavior (B) from attitudes (Aact) and normative beliefs (NBs). Using a variation of theAjzen and Fishbein (Journal of Experimental Social Psychology, 1970,6, 466–487) method, potential limitations of the model were investigated. It was found that certain situational factors were capable of altering the nature of the model significantly. Aact carried a nonsignificant regression weight when the participant had had no prior direct experience with the act and carried a significant weight when the participant had had experience with the act. NB carried a nonsignificant weight under competitive motivational set conditions and a significant weight under cooperative set conditions. These findings raise the question of the generality of the Fishbein model, since different prediction models were required by different situational conditions. The hypothesized association between attitude and behavior appears to be dependent on prior experience with the behavior, while the association between norms and behavior seems to be dependent on consistency between personal motivation and perceived social expectations.  相似文献

Among the variables affecting comprehension of linguistic stimuli by aphasic subjects are syntactic complexity and processing time. Comprehension performance of 15 aphasic adults was studied while altering the rate of speech presentation and varying the pause time between the major phrases within sentences of increasing grammatical complexity.Simple Active Affirmative Declarative Sentences, Negative, and Passive sentences were presented (1) at the rate of 150 words per minute (wpm) with 1-sec interphrase pause time (IPT); (2) 150 wpm with no pauses; (3) 120 wpm with 1-sec IPT; (4) 120 wpm with no pauses added.Performance was seen to vary with increasing syntactical complexity and as a function of processing time. Greater comprehension was seen with active affirmative than negative; greater with passive affirmative than with active negative. Clinical implications are discussed. Subjects demonstrated greater comprehension when sentences were presented at slower than normal rate; addition of interphrase pause time intervals aided comprehension. Combining slower rate of presentation and IPT intervals provided greatest increase in auditory processing time and showed concomitant increase in comprehension performance.  相似文献

Testing a component of a theoretical model which postulates that low levels of communication effectiveness accompany the social and affective problems presented by aggressive children, the study compared the communication skills of a group of aggressive (n = 49) and nonaggressive (n = 49) elementary school children (selected on the basis of teacher ratings) in a structured and cooperative communication task. Based on direct observational measures of communication effectiveness and aggression, and on teacher, peer, and self-rating measures of peer rejection and depressive symptoms, results showed that (a) aggressive children exhibited less effective communication skills and more disruptive communication skills than nonaggressive peers; (b) aggressive children experienced higher levels of peer rejection and depressive symptoms than nonaggressive peers; and (c) group differences in communication effectiveness could not be accounted for by differences in observed aggression and remained significant, even after controlling for differences in peer status and affective functioning. These findings highlight the role that ineffective communication may play in the development and maintenance of aggression and have important theoretical and applied implications, which are briefly discussed. © 1994 Wiley-Liss, Inc.  相似文献
