Description

Temporal discounting is the decrease in subjective value of rewards by the delay to its receipt. In psychology of learning, in a choice situation between a smaller-sooner reward and a larger-later reward, preference for the former alter native is defined as impulsiveness whereas preference for the latter alternative is defined as self-control. Degree of temporal discounting represents the degree of impulsiveness. Previous studies have reported relationship between temporal discounting and mental disorder. Some of the studies have investigated the relationship between temporal discounting and social anxiety characterized by fear and avoidance of social situation; the results are not consistent among studies. This paper reviews studies reporting the relationships between temporal discounting and mental disorder, especially, examining factors that may cause the inconsistency of results among studies on social anxiety. Based on the findings of the previous studies, we discuss the possibility that the concept of temporal discounting could be applied to social anxiety, expecting the clarification of the mechanism of social anxiety and the promotion of applicability of temporal discounting to other kinds of mental disorders.
