Behavioral Inhibition System The BIS is the set of brain structures that causes people to inhibit movement, to pull back from the stimulus they just encountered. Analogy: Psychic brake pedal When the BIS is operating, the person may stop whatever is going on and scan the environment for further clues. The preceeding lecture dealt with the approach system. This approach system is complimented by a second neural system Sensitive to punishers --> BIS Sometimes referred to as withdrawl system or avoidance system Activity in these parts of the brain Causes people to inhibit movement Pull back from the stimulus they just encountered
