Autonomic Synchronization under Three Task Conditions and its Impact on Team Performance.

Abstract

Psychologists have had a long-standing interest in the connections between group processes and team performance. The biopsychosocial perspective has piqued an interest in the connection between team processes and performance and coordinated and synchronized physiological arousal levels among team members. Studies of synchronization in work teams have been stalled by the lack of a metric that captures the total synchronization within teams of three or more people. This study examined how synchronized physiological arousal does in fact connect to team performance and related group process outcomes by utilizing the SE coefficient developed by Guastello and Peressini. Forty-three groups of 3 to 8 participants (total N = 197) participated in a survival simulation. Synchroniza-tion coefficients were produced for three task segments: watching an orientation video together, an individual decision task, and a group decision task. Primary results showed: (a) Synchronization was greater in larger groups across the three task segments. (b) A combination of the three synchronization coefficients - higher during the team task and lower otherwise - was correlated with higher workload ratings for performance demands, greater team dissatisfaction, and lower demands for time-sharing between the individual and the team.
