The social interactions of task groups were investigated for their influences on member moods. Initially, participants' received an induction of positive, negative, or neutral moods via listening to music that continued throughout the experimental session. Moods were measured after the induction. Students then made decisions on four choice dilemmas alone or as members of a four-person group. Subsequently, positive and negative moods were again measured. Positive moods of participants who worked with other group members on the task were sustained, but diminished for those working alone. Negative moods of participants working in groups diminished over time, but were sustained for those working individually. These results were interpreted in the context of motivational systems theory of group involvement (Park & Hinsz, 2006). Additionally, although there was a tendency for member moods to homogenize over assessments, this did not reach significance. Results document the affective benefits that often accompany task group interaction suggesting that group interaction has features of positive mood induction. This report highlights the need to consider social influences on affect in task settings so that group dynamics, processes, and behaviors can be better understood.
研究了任务小组的社会互动对成员情绪的影响。最初，参与者通过听贯穿整个实验过程的音乐来诱导出积极、消极或中性情绪。诱导情绪后进行测量。然后，学生们独自或作为四人小组的成员对四个选择困境做出决定。随后，再次测量积极和消极情绪。与其他小组成员一起完成任务的参与者的积极情绪得以维持，但独自工作的参与者的积极情绪有所减弱。在小组中工作的参与者的消极情绪随着时间的推移而减弱，但独自工作的参与者的消极情绪则持续存在。这些结果是在群体参与动机系统理论的背景下进行解释的（帕克和欣茨，2006年）。此外，尽管在评估过程中成员情绪有趋于同质化的趋势，但这并不显著。结果记录了任务小组互动常常带来的情感益处，表明小组互动具有积极情绪诱导的特征。本报告强调了在任务环境中考虑社会对情感的影响的必要性，以便更好地理解群体动态、过程和行为。
