However, we lack a theoretical framework to understand when the frequency of leader emotional displays may or may not explain signicant variance in follower performance. To advance knowl- edge in this emerging line of research, we integrate Emotion As Social Information (EASI) theory with attribution theory to explore boundary conditions of the relationships of the frequencies of positive and negative leader emotional displays with follower performance. Results based on leaders and followers in three organizations show that leader surface acting acted as a boundary condition, neutralizing the effects of the frequencies of positive and negative leader emotional dis- plays toward an individual follower on that follower's performance. In addition, higher frequency of negative emotional displays shown by the leader to all group members acted as a boundary condition, neutralizing the effect of the frequency of negative leader emotional displays toward an individual follower on that follower's performance. This work advances our understanding of the way the frequency of leader emotional displays may inuence follower performance, intro- duces new types of contingency factors to the leader emotion area, and helps extend emotional labor theory to the leadership context. © 2015 Elsevier Inc.

Consistent with Gooty, Connelly, Griffth and Gupta (2010) and Gooty, Gavin, and Ashkanasy (2009), we regard leader affect as a broad construct that includes both leader emotion (i.e., an intense, short-term, and specic cog- nitive response to environmental stimuli) and mood (i.e., less intense, long-term, and diffused emotional states). A predominant the- oretical explanation as to why leader affect may inuence followers is that followers automatically pick upor share their leaders' affect through emotional contagion (Hateld, Cacioppo, & Rapson, 1994), such that leader positive affect results in positive follower affect, behaviors, and outcomes, whereas leader negative affect leads to negative follower affect, behaviors, and outcomes (Bower, 1981; Clark & Taraban, 1991; Fredrickson, 2001; Porath & Erez, 2007; Rajah, Song, & Arvey, 2011).
