Reinforcement Sensitivity Theory

Reinforcement Sensitivity Theory (RST) explains how our brain's systems influence our behavior based on different types of cues and rewards. It suggests there are three key brain systems: the Behavioral Activation System (BAS), which motivates us to seek rewards and pursue positive outcomes; the Behavioral Inhibition System (BIS), which detects potential threats and causes us to feel cautious or anxious; and the Fight-Flight-Freeze System (FFFS), which triggers immediate responses to danger. Together, these systems shape how we respond to our environment, balancing approach, avoidance, and threat detection, influencing personality and behavior patterns.
