Behavioral Activation System

Also written as: BAS — Behavioral Activation System

Neurobiological system that motivates approach behaviors toward rewarding stimuli and goal achievement.

Full Definition

The Behavioral Activation System (BAS) is a neurobiological motivational system that drives individuals toward rewarding stimuli and goal-directed behaviors. Originating from Gray's reinforcement sensitivity theory, BAS activity is associated with positive emotions, approach behaviors, and reward sensitivity. In behavioral medicine, understanding BAS functioning helps clinicians assess motivation patterns, design reward-based interventions, and predict treatment engagement across various populations.
