This study investigated the influence of teleconferencing medium and status on users' reaction to the medium. Subjects received either high or medium status inductions, and subgroups solved a problem in two node audio, video, and face-to-face conferencing configurations. These subgroups proceeded through the three media treatment conditions in counterbalanced order, and responded to scales measuring the aestheticism, evaluation, privacy, potency, and activity of the medium. Analysis indicated both face-to-face and video conferencing elicited more positive aestheticism and evaluation reactions than the audio conferencing medium. Face-to-face and audio conferencing media were perceived as being more private than the video teleconferencing medium while both video and audio media were perceived as being more potent than face-to-face conferencing. The analysis revealed neither an activity of the medium nor status main effect. The results were discussed in light of information theory. 相似文献

Social identity theory predicts a link between self-esteem and intergroup discrimination. Previous research has failed to find consistent support for this prediction. Much of this research has, however, been beset by a number of methodological shortcomings. These shortcomings may have hindered attempts to discern a consistent relationship between self-esteem and intergroup discrimination. The current investigation sought to overcome these difficulties by utilizing, realistic groups, multidimensional measures of self-esteem and testing self-esteem before and after the manifestation of intergroup evaluative bias. The results demonstrate that when the members of realistic groups engage in evaluative intergroup bias, the esteem in which they hold specific self-images is enhanced. Of the 13 facets of self-esteem delineated by the instrument used in the present study significant increases were found in six particular domains: honesty, academic ability, verbal ability, physical appearance, religion and parental relations. Global self-esteem was unaffected by the display of bias. These findings emphasize the importance of using realistic groups and domain specific self-esteem when attempting to assess the role of self-esteem in intergroup discrimination. 相似文献

RELATIONS BETWEEN WORK GROUP CHARACTERISTICS AND EFFECTIVENESS: IMPLICATIONS FOR DESIGNING EFFECTIVE WORK GROUPS 总被引:32,自引:0,他引:32
Five common themes were derived from the literature on effective work groups, and then characteristics representing the themes were related to effectivness criteria. Themes included job design, interdependence, composition, context, and process. They contained 19 group characteristics which were assessed by employees and managers. Effectiveness criteria included productivity, employee satisfaction, and manager judgments. Data were collected from 391 employees, 70 managers, and archival records for 80 work groups in a financial organization. Results showed that all three effectiveness criteria were predicted by the characteristics, and nearly all characteristics predicted some of the effectiveness criteria. The job design and process themes were slightly more predictive than the interdependence, composition, and context themes. Implications for designing effective work groups were discussed, and a 54-item measure of the 19 characteristics was presented for future research. 相似文献

The extant research examining the relationship between public speaking trait anxiety and heart rate has produced mixed findings. Some studies observe only weak relationships, whereas others report significant relationships between these variables. H. J. Eysetick has maintained that the degree of relationship between traits and heart rate depends on the stress levels under which the respondents perform when heart rate data are collected. An inspection of the existing studies shows that, consistent with Eysenck's observation, the studies reporting relationships between public speaking trait anxiety and heart rate were conducted under relatively low-intensity conditions in comparison to those reporting no such relationships. In the present study, heart rates of both anxious and nonanxious speakers were measured under both high- and low-intensity conditions. Results indicated that (a) heart rates of anxious speakers were significantly higher than those of nonanxious speakers when both performed under low-intensity conditions, but (b) heart rates were not different for anxious and nonanxious speakers when performing in high-intensity environments. These results provide a reconciliation of the inconsistent research findings and partially support the extension of Eysenck's conceptualization to communication apprehension theory and research. 相似文献
