Induced mood and selective attention.
Subjects (N = 60) were randomly assigned to an elated, depressed, or neutral mood-induction condition to assess the effect of mood state on cognitive functioning. In the elated condition film fragments expressing happiness and euphoria were shown. In the depressed condition some frightening and distressing film fragments were presented. The neutral group watched no film. Mood states were measured using the Profile of Mood States, and a Stroop task assessed selective attention. Both were presented by computer. The induction groups differed significantly in the expected direction on the mood subscales Anger, Tension, Depression, Vigour, and Fatigue, and also in the mean scale response times, i.e., slower responses for the depressed condition and faster for the elated one. Differences between conditions were found in the errors on the Stroop: in the depressed condition were the fewest errors and significantly longer error reaction times. Speed of error was associated with self-reported fatigue.
