Educably mentally retarded (EMR) students and nonhandicapped students from their mainstream classes completed semantic differential ratings of a stereotypic popular teen-ager, juvenile delinquent, and special education student. Subjects also rated their global self-concepts and situation-specific self-concepts within the mainstream and the special class settings. Ratings were done at the beginning (Time 1) and the end (Time 2) of a semester. Results showed that mainstream classes did not "de-label" EMR students. Within the mainstream class, the number of EMR students who saw themselves as similar to a special education student significantly increased over time. Moreover, at Time 2, EMR students were more likely to think of themselves as similar to a special education student in their mainstream class than in their special education class. However, EMR subjects' global self-concepts did not change. Implications for mainstreaming are discussed. 相似文献

The impact of pre-employment integrity testing on employee turnover and inventory shrinkage losses 总被引:1,自引:0,他引:1
Thomas S. Brown Dr. John W. Jones William Terris Brian D. Steffy 《Journal of business and psychology》1987,2(2):136-149
A major home improvement chain located primarily in the western United States initiated the use of thePersonnel Selection Inventory, a written integrity test, as part of its pre-employment hiring process. For two years only, those job applicants who passed this test and other pre-employment criteria were hired by the chain. Following the introduction of the inventory, there was: (1) a 50% reduction in the number of employee terminations for theft, illegal drug use, and violence over a five year period and (2) a savings in shrinkage losses that amounted to over two million dollars over a two year period. 相似文献

San Diego suicide study: comparison of gay to straight males 总被引:1,自引:0,他引:1
Previous large studies of completed suicides have not considered sexual orientation in their data analyses. In this study, data from the known homosexual subpopulation (13 males, aged 21-42) in a series of 283 suicides were examined. They were compared with all other aged male suicides 21-42 (n = 106). Both groups showed considerable substance abuse plus a variety of other psychiatric diagnoses. Both also had a high frequency of relationship difficulties near the time of death. Gays who committed suicide did not have a history of more police trouble and were no more likely to be living alone than the comparison group. They did not have more prior suicide attempts or previous psychiatric treatment. We conclude that, among the factors examined here, there appears to be little difference between gay and heterosexual male suicides. 相似文献

Brian McKeon 《Behavior research methods》1986,18(3):304-306
This report describes the methods used to improve the performance of a three-dimensional movement-tracking system that is based on infrared cameras and light-emitting diodes. The technique has general application to similar systems with other types of cameras. The improvement was obtained by postprocessing to correct camera-image distortions. This procedure yielded a six-fold increase in accuracy. With a 900-mm-cube viewing volume, the error in locating a point was reduced to less than 3 mm. 相似文献

A self-attention approach to the effect of the group on the individual is applied to the phenomenon of participation in religious groups. Previous work indicates that group members become more self-attentive, and thus more concerned with matching to standards of appropriate behavior, as the relative size of their subgroup decreases. This suggests that, in the context of religious groups, members of a congregation will be more self-attentive, and thus more likely to participate in the religious group, when there are fewer congregation members relative to the number of ministers. The results of analysis of ten archival records of participation in religious groups support this perspective. The importance of self-attention processes in religious group settings is discussed. 相似文献

Summary The feature-integration model of visual information processing (Treisman & Gelade, 1980) predicts perceptual errors based on the incorrect grouping of stimulus features in multi-element displays. Experiment 1 examined the frequency of such errors with a tachistoscopic bar probe task using letters and novel patterns with a production response. A substantial proportion of the errors did involve figures that were not present in the display but contained combinations of features which had been present. Such errors were especially prominent with novel patterns. The results with letters suggested that such responses were due to guessing, not feature migration, and this was confirmed by Experiment 2. In the second study, responses were collected for single character displays but were scored as if they had been responses to the multielement displays in Experiment 1. The results showed the same high proportion of illusory conjunction errors as the previous results and it was concluded that both results were due to guessing. Spatial confusions in the bar probe task with letters appear to involve whole characters, not character features.This research was supported by grant A-9581 from the National Science and Engineering Council of Canada to the senior author. This research was reported as a paper to the annual meeting of the Canadian Psychological Association, Toronto, 1981. Ian Morrison is now a post-doctoral fellow at the Department of Psychology, Carnegie-Mellon University. 相似文献
