Feeling differently, creating together: Affect heterogeneity and creativity in project teams
研究团队中成员同时存在积极和消极情感（情感异质性）如何通过信息交换与精加工过程影响创造力，并发现交互记忆系统能强化这一过程。
Summary Differently valenced affective states stimulate different information search and processing styles. Dual‐tuning theory suggests that in combination, the styles tuned by positive affect (broad information search and flexible thinking) and by negative affect (persistent detailed search and critical thinking) facilitate creativity better than a single affect alone. Through this lens, we argue that the simultaneous presence of team members experiencing differently valenced affective states (affect heterogeneity) may facilitate team creativity by providing access to more varied information and perspectives. To extract creative benefit from these enhanced informational resources, teams must engage in an information exchange and elaboration process. However, affect heterogeneity may also threaten this process. We suggest that effective information exchange and elaboration is more likely to occur when the team has a well‐developed transactive memory system to legitimize and coordinate the differences flowing from affect heterogeneity among members. We tested our hypotheses among 59 teams in a within‐team design in which we measured team affect heterogeneity, information exchange and elaboration, and creativity in each of 4 weeks of a 13‐week project. Results supported our hypotheses, including the mediating role of information exchange and elaboration, and the moderating role of team transactive memory system.
