Sakamoto et al. also hoped to identify factors as to why study participants experienced alterations in the seasonal pattern of their depressive episodes. The research conducted by Sakamoto and her partners falls into the core area of abnormal behavior, more specifically, the areas of individual differences and mood disorders.
