ON THE INDUCTION OF MOOD

Increasing interest in the relation between emotion and cognition has led to the development of a range of laboratory methods for inducing temporary mood states. Sixteen such techniques are reviewed and compared on a range of factors including success rate, the possibility of demand effects, the intensity of the induced mood, and the range of different moods that can be induced. Three different cognitive models (self-schema theory, semantic network theory, and fragmentation theory) which have been successfully used to describe long-term mood states, such as clinical depression, are elaborated to describe the process of temporary mood induction. Finally, the use of mood induction is contrasted with alternative methods (such as the study of patients suffering from depression) for investigating emotion. © 1990.
