Jeffrey Gray

Jeffrey Gray was a notable psychologist known for his work on how our brain influences behavior through two primary systems: the Behavioral Approach System (BAS) and the Behavioral Inhibition System (BIS). The BAS drives us toward rewards and positive outcomes, fostering motivation and enthusiasm, while the BIS prompts caution and anxiety to avoid negative situations. Gray’s theories help explain differences in personality, such as why some people are more daring or more cautious, and have been influential in understanding emotional responses and vulnerability to mental health issues like anxiety and impulsivity.
