A Behavioral Inhibition System refers to a subsystem of the brain that produces Anxiety and inhibits ongoing Behavior in the presence of novel events, innate Fear stimuli, and signals of non-reward or punishment. A behavioral avoidance (or inhibition) system (BIS) is said to regulate aversive motives, in which the goal is to move away from something unpleasant. Behavioral inhibition system (BIS) is thought to be mediated by the frontal cortex and limbic system.
Description
The Behavioral Inhibition System is a theoretical concept in psychology that refers to a neurobiological system responsible for detecting threats, inhibiting behaviors, and promoting avoidance in response to potential harm. It is part of the broader behavioral approach system, which is responsible for seeking rewards and pursuing goals. Individuals with a highly active Behavioral Inhibition System are more prone to anxiety, fear, and avoidance behaviors. This system is thought to be related to the personality trait of neuroticism and is associated with heightened sensitivity to negative stimuli and a tendency to overestimate potential threats.
