Cross-study differences in the contributions of work attitudes to the turnover process led us to (a) estimate the six relations among job satisfaction, organizational commitment, turnover intention/withdrawal cognitions, and turnover using meta-analysis; (b) assess the effects of several psychometric moderators on those relations; and (c) compare the influences of satisfaction and commitment in the turnover process by applying path analysis to the meta-analytic correlations. Based on aggregations involving a total of 178 independent samples from 155 studies, results showed that (a) satisfaction and commitment each contribute independently to the prediction of intention/cognitions; (b) intention/cognitions are predicted more strongly by satisfaction than by commitment; (c) intention/cognitions mediate nearly all of the attitu-dinal linkage with turnover; and (d) attitudinal contributions to the turnover process vary with the use of single- versus multi-item scales, the 9- versus 15-item version of the Organizational Commitment Questionnaire, and turnover intention versus withdrawal cognition scales.  相似文献

A family of coefficients of relational agreement for numerical scales is proposed. The theory is a generalization to multiple judges of the Zegers and ten Berge theory of association coefficients for two variables and is based on the premise that the choice of a coefficient depends on the scale type of the variables, defined by the class of admissible transformations. Coefficients of relational agreement that denote agreement with respect to empirically meaningful relationships are derived for absolute, ratio, interval, and additive scales. The proposed theory is compared to intraclass correlation, and it is shown that the coefficient of additivity is identical to one measure of intraclass correlation.The author thanks the Editor and anonymous reviewers for helpful suggestions.  相似文献

The value of self-efficacy as a predictor of counselling skills performance in a graduate counselling class was evaluated with 31 trainee counsellors. Three measurements of self-efficacy were taken: before, midway through, and at the end of a microcounselling skills training programme which was taught over six weekly three-hour sessions. Although there was a wide distribution of self-efficacy reports, none of the estimates of grade were significantly positively associated with counselling skills. Implications for counsellor educators are discussed.  相似文献

Summary We investigated the hypothesis that the detection of a scene segmentation is facilitated when coincident with a segmentation in another visual dimension. We measured the percentage of the correct detection of horizontal or vertical tritanopic color segmentations perpendicular to, or coincident with, segmentations produced by a subjective-contour stimulus. We found that color discrimination improves when the color segmentation is coincident with the segmentation formed by the subjective contour.In a second experiment, using a yes-no procedure, we found that sensitivity for the detection of luminance segmentations coincident with subjective-contour segmentations increased. However, the detectability of luminance segmentations coincident with a line deteriorated (the gap effect). We conclude that the notion of facilitated detection of coincident segmentations has several problems that undermine its intuitive appeal.  相似文献

This study examines how gender is related to self-evaluations of information to discuss current social and political issues. The sample is one of predominantly white (96%) college graduates. Using alumni samples, we look at how members of four classes that span 20 years evaluate their knowledge to hold conversations on a variety of public affairs issues ranging from the Strategic Defense Initiative to government funding of abortion. We find gender differences, with men perceiving themselves more knowledgeable in conversations and women less so. We raise the possibility that they are “doing gender.” The implications of these findings are explored.  相似文献

An experiment was conducted to determine how visual attention is allocated in response to pairwise combinations of location, color, and size cues. Subjects viewed displays of eight letters arranged into an 'X' pattern emanating from a central fixation point. The letters varied on the dimensions of location (foveal or parafoveal positions), size (large or small), and color (red or blue). Seven of the letters were 'X's and the remaining, critical letter was either an 'R' or an 'L'. Subjects were given advance cues about characteristics of the critical letter on two of the three dimensions (location size, and color). The cues varied in their validity such that on any trial either both dimensions were validly cued, one dimension was validly cued while the other was invalidly cued, or both cues were invalid. Subjects were instructed to try to use the cues to find the critical letter, and response times to identify it as an 'R' or an 'L' served as the main dependent measure. Two models were evaluated against the data; in one, location cues are viewed as having distinct effects on an early stage of attention whereas color and size cues operate only in a later, selection stage. In the other model, all cues are used in a similar way to select display items for serial, focal attention. In general, the serial processing model provides a more complete account of the data.  相似文献
