ABSTRACT

This study attempted to explain the influences that Behavioral Activation System (BAS) as neurobiological vulnerability has on bipolar symptom in terms of cognitive response style to positive affect. The hypotheses to be test were that after being activated by BAS the positive affect is firstly enhanced by positive rumination and then extinguished rapidly by dampening with such chain actions resulting in mood swings and bipolar symptom. A total of 227 students of Cyber University in Seoul participated to answer questionnaires on online that measure BAS sub-scales in BIS/BAS Scale, Extended Responses to Positive Affect Questionnaire (E-RPA), and Mood Disorder Questionnaire (MDQ). As results, the positive rumination and the dampening mediated sequentially the relationship between BAS and bipolar symptom. In terms of cognitive mechanism, the process through which the biological motivation system called BAS develops into bipolar symptom may consist of sequential joint actions of upward and downward cognitive modulations culminating in dysfunction of positive affect. In addition, clinical implications to help the control of positive affect for bipolar disorders are discussed, along with the limitations of current study and the directions for future ones.
