Although the rapid development of information technology has led to the increasing use of computer‐mediated communication (CMC), few studies have examined the relational aspect of mixed‐mode groups that use both face‐to‐face (FTF) communication and CMC. A field study comprising 42 student groups was conducted to assess the relationships among communication time, cohesion, and performance in mixed‐mode groups. The findings suggest that time spent in FTF communication significantly predicted group social cohesion, but time spent in CMC did not. In contrast, group task cohesion was predicted by time spent in CMC but not by time spent in FTF communication. Time spent in CMC was also a strong predictor of group task performance. These results suggest that FTF communication contributes to the social aspect of mixed‐mode groups and that CMC is beneficial to their task‐related aspect. The findings of mediation analyses showed a significant indirect effect among time spent in FTF communication, group social cohesion, and group contextual performance. In other words, time spent in FTF communication had a positive effect on group social cohesion, which in turn positively affected group contextual performance. However, no mediating effect was found among time spent in CMC, group task cohesion, and group task performance. Theoretical and practical implications of these findings are discussed. 相似文献

Toward a better understanding of the effects of hindrance and challenge stressors on work behavior 总被引:1,自引:0,他引:1

This study investigated the processes whereby hindrance and challenge stressors may affect work behavior. Three mechanisms were examined to explain the differential effects these stressors have demonstrated: job satisfaction, strains, and work self-efficacy. A model is proposed in which both types of stressors will result in increases in strains, but that job satisfaction is primarily involved in the relationship between hindrance stressors and citizenship behavior, and efficacy is involved in the relationship between challenge stressors and job performance. Although the results generally supported the dual-stressor framework showing meaningful relationships to the work outcomes through the proposed processes, the link between work self-efficacy and job performance was not significant. This model was analyzed using multi-source data collected from 143 employees from a variety of organizational settings. Implications for the conceptualization of stressors and the development of interventions are discussed. 相似文献

An extensive commitment to nonwork roles was negatively associated with the job performance of 182 women legal secretaries. In addition to its direct negative effect on job performance, nonwork role commitment had both a negative indirect effect (through emotional energy expended on nonwork roles) and a positive indirect effect (through resources acquired from nonwork roles) on job performance. Consistent with a family-to-work conflict perspective, the negative effect was stronger than the positive effect. We suggest that the level and type of job occupied by the respondents in the study may have been responsible for the dominance of the negative effect and encourage researchers to examine the contextual influences that might explain the conditions under which commitment to life outside of work dampens or promotes performance in the work domain. 相似文献

Previous research has found that people are often averse to inequity, even when it works to their own advantage. The present research extends previous demonstrations of inequity aversion by examining how it plays out in a real-world context in which self-interest motivations and competitive pressures are substantial. National Basketball Association games were examined and instances of obviously incorrect foul calls were identified. Players were found to make a substantially lower percentage of the foul shots they were awarded as a result of incorrect calls, indicating that they were troubled by the inequity. This drop-off in performance was only observed when the shooter's team was ahead, highlighting the trade-off between the two conflicting motives of self-interest (the desire to win) and inequity aversion. 相似文献

Cassidy, G.G. & MacDonald, R.A.R. (2010). The effects of music on time perception and performance of a driving game. Scandinavian Journal of Psychology 51, 455–464. There is an established and growing body of evidence highlighting that music can influence behavior across a range of diverse domains ( Miell, MacDonald, & Hargreaves 2005 ). One area of interest is the monitoring of “internal timing mechanisms”, with features such as tempo, liking, perceived affective nature and everyday listening contexts implicated as important ( North & Hargreaves, 2008 ). The current study addresses these issues by comparing the effects of self‐selected and experimenter‐selected music (fast and slow) on actual and perceived performance of a driving game activity. Seventy participants completed three laps of a driving game in seven sound conditions: (1) silence; (2) car sounds; (3) car sounds with self‐selected music, and car sounds with experimenter‐selected music; (4) high‐arousal (70 bpm); (5) high‐arousal (130 bpm); (6) low‐arousal (70 bpm); and (7) low‐arousal (130 bpm) music. Six performance measures (time, accuracy, speed, and retrospective perception of these), and four experience measures (perceived distraction, liking, appropriateness and enjoyment) were taken. Exposure to self‐selected music resulted in overestimation of elapsed time and inaccuracy, while benefiting accuracy and experience. In contrast, exposure to experimenter‐selected music resulted in poorest performance and experience. Increasing the tempo of experimenter‐selected music resulted in faster performance and increased inaccuracy for high‐arousal music, but did not impact experience. It is suggested that personal meaning and subjective associations connected to self‐selected music promoted increased engagement with the activity, overriding detrimental effects attributed to unfamiliar, less liked and less appropriate experimenter‐selected music. 相似文献

This longitudinal study examined associations between three after-school program quality features (positive staff–child relations, available activities, programming flexibility) and child developmental outcomes (reading and math grades, work habits, and social skills with peers) in Grade 2 and then Grade 3. Participants (n = 120 in Grade 2, n = 91 in Grade 3) attended after-school programs more than 4 days per week, on average. Controlling for child and family background factors and children’s prior functioning on the developmental outcomes, positive staff–child relations in the programs were positively associated with children’s reading grades in both Grades 2 and 3, and math grades in Grade 2. Positive staff–child relations also were positively associated with social skills in Grade 2, for boys only. The availability of a diverse array of age-appropriate activities at the programs was positively associated with children’s math grades and classroom work habits in Grade 3. Programming flexibility (child choice of activities) was not associated with child outcomes. 相似文献
