Mood changes during training laboratory

Abstract

30 trainees completed a mood adjective check list at 5 periods during a 10-day sensitivity training laboratory for management. Results indicated that differences and predictable shifts in mood do occur. Specifically, skepticism and anxiety decreased as most trainers would expect; other moods, like depression and aggression, showed the effects of particular laboratory procedures. The results also provided independent evidence of the validity of the factored Nowlis and Green check list of mood adjectives. Findings generally were consistent with trainer beliefs about mood changes in trainees and conformed to expectations about the effects on mood of defeat or victory in intergroup competition.
