Catching moods and hitting runs: Mood linkage and subjective performance in professional sport teams.

Are the moods and subjective performances of professional sports players associated with the ongoing collective moods of their teammates? Players from 2 professional cricket teams used pocket computers to provide ratings of their moods and performances 3 times a day for 4 days during a competitive match between the teams. Pooled time-series analysis showed significant associations between the average of teammates' happy moods and the players' own moods and subjective performances; the associations were independent of hassles and favorable standing in the match. Mood linkage was greater when players were happier and engaged in collective activity. An intraperson analysis of data from these teams and 2 other teams showed that mood linkage was also greater for players who were older, more committed to the team, and more susceptible to emotional contagion. The results support and extend previous findings concerning mood linkage.
