Mediating effects of psychological safety in the relationship between team affectivity and transactive memory systems
研究了项目团队中积极和消极情感如何通过心理安全感影响交互记忆系统的形成，发现消极情感会降低心理安全感进而阻碍交互记忆系统，对团队管理有参考价值。
Summary In this research, we develop a framework for understanding the emergence of transactive memory systems (TMS) in project‐based teams characterized by different levels of group level positive affectivity (PA) and negative affectivity (NA). With a focus on enhancing understanding of the means of transmission, we test the mediating role played by group level psychological safety (PS) in the relationship between team affectivity and TMS. From a sample of 107 software implementation project teams, in a lagged field study, we find support for a mediated model in which high group NA, but not group PA, promotes environments psychologically unsafe for interpersonal risk‐taking (low PS) and which are negatively associated with TMS. This study extends prior research on the differential effects of PA and NA, by contributing to the limited research on group affectivity, environmental antecedents of TMS, and the mediating role of PS for predicting group level transactive processes and structures.
