Behavior modification is the field

Behavior modification is the field of psychology concerned with analyzing and modifying human behavior.
■ Analyzing means identifying the functional relationship between environ- mental events and a particular behavior to understand the reasons for behavior or to determine why a person behaved as he or she did. ■ Modifying means developing and implementing procedures to help people change their behavior. It involves altering environmental events so as to influence behavior. Behavior modification procedures are developed by professionals and used to change socially significant behaviors, with the goal of improving some aspect of a person’s life.
