Trait Activation in Teams: Personality, Psychological Safety, Speaking Time, and Member Effectiveness

Framed in trait activation theory, we examine the influence of personality, psychological safety, and the mediating effect of speaking time on team member effectiveness ratings in team meetings with 21 student teams (110 individuals). Extraversion was positively related to speaking time and indirectly related to team member effectiveness via speaking time. Although psychological safety was not related to speaking time, it was positively related to team member effectiveness. No significant effects were found for emotional stability. This work provides theoretical rationale and empirical support for the traits and behavior in team meetings that influence ratings of team member effectiveness.
