Behavioral Inhibition System
Also written as: BIS — Behavioral Inhibition System
Neurobiological system that promotes avoidance behaviors and inhibits responses to threatening or punishing stimuli.
Full Definition
The Behavioral Inhibition System (BIS) is a neurobiological system responsible for inhibiting behavior in response to signals of punishment, non-reward, or threat. This system promotes cautious, avoidant behaviors and is associated with anxiety, worry, and behavioral inhibition. In behavioral medicine, BIS sensitivity influences how patients respond to treatment challenges, their willingness to engage in exposure-based interventions, and their overall approach to health behavior change.
Usage
Usage note: Commonly abbreviated as BIS in clinical documentation.
