Abstract
The present case report describes the spontaneous occurrence of catharsis in a tense and depressed young woman who participated in a research study designed to investigate ways of increasing the accessibility of emotional memories. During the research she became extremely distressed and showed both somatic and cognitive components of catharsis. Prior to this, subjective and physiological indices of anxiety and tension were evident and marked differences in bilateral finger temperature indicated the presence of pronounced laterality effects. Following catharsis both subjective and physiological measures revealed a substantial reduction in tension and the previously observed laterality effects virtually disappeared. This case report thus describes a rare portrayal of the subjective and physiological effects of catharsis and documents the positive, beneficial nature of the effects observed.
