A meta-analysis of the effects on worker productivity of 11 types of psychologically based organizational interventions showed that such programs, on average, raised worker productivity by nearly one-half standard deviation. The strength of effects was found to vary by type of intervention, criterion of productivity, contextual factors in organizations, and features of research design. Also discussed in the paper are comparisons of conclusions reached through meta-analysis versus traditional methods of literature review.  相似文献

Impression formation research (Snyder & Swann, 1978) suggests that people engage in information seeking strategies designed to confirm their impressions of others. In an extension of this work to the selection interview, Sackett (1982) found, however, that subjects did not consistently adopt a confirmatory information seeking strategy. This study is a further examination of Snyder and Swann's theory. In simulated interviews 170 subjects (1) read resumes of hypothetical applicants, (2) selected ten questions to ask each applicant, (3) received written responses to each question immediately on its selection, and (4) rated each applicant's suitability. An interaction accounting for 73% of variance indicated that applicant ratings were based primarily on the content of applicants' responses, but initial impressions also played a part. No clear-cut, confirmatory information seeking strategy was observed.  相似文献

The role of visual memory in learning to spell words was investigated through a matching task on which one nonsense word was presented, then a second word identical in spelling or differing in one letter was presented. Ten pairs of 9th and 10th-grade students, matched for intelligence and sex but of different spelling ability, were asked to indicate whether word pairs were spelled the same or differently. The two words of a pair were either the same or different in print size or letter case. Significant effects were obtained for spelling ability, print size (same or different), and letter case (same or different), and the interaction of size X case, providing evidence for the use of visual memory by both good and poor spellers in learning to spell words. Good spellers were equally able to identify matched and mismatched pairs, while poor spellers showed greater difficulty in identifying mismatches than matches, supporting Frith's (1980) "partial cues" explanation of poor spelling performance.  相似文献

This paper examines the relationship between education, management style, and organizational effectiveness. The increasing education level in the society is pointed to as a strong force toward a more participative management style. However, it is stressed that much of the education which is taking place in the United States may not equip people to participate effectively in a more democratically managed workplace. Finally, a model of a new more participative management style is presented and its relationship to education and skills is explicated.  相似文献

The purposes of this study were (1) to replicate a right visual-field advantage for a version of the Embedded Figures Test modified for tachistoscopic presentation and (2) to test for a relationship between field independence and performance on modified Embedded Figures Test items presented to the right visual-field. 34 right-handed subjects were presented Embedded Figures Test items to the left, center, and right visual-fields for 150 msec. The Group Embedded Figures Test was also given. Results showed a right visual-field advantage on the modified embedded-figures test and (2) a negative relationship between Group Embedded Figures Test performance and right visual-field scores. These findings were discussed in terms of the differences between the two versions of the embedded-figures test, memory for simple figures, specificity of judgment, and sustained versus tachistoscopic perception. A tentative conclusion suggests that a better internal representation of the briefly presented complex figures places field-independent subjects at a disadvantage on the modified version of the test.  相似文献

Individuals with brain damage often encounter visual perceptual and visuo-motor difficulties. Studies have indicated an improvement in exceptional individuals' performances when the colors of figure-ground materials were reversed. Effects of reversals were studied for spastic cerebral palsied and normal children's scores on the Developmental Test of Visual-motor Integration and the Motor-free Visual Perception Test. Normal children performed better than the cerebral palsied children on all tests; the cerebral palsied children performed best on the reversed-format Motor-free Visual Perception Test. Reversal affected neither group's scores on visual-motor integration.  相似文献
