Behaviorist

A behaviorist is a psychologist or scientist who focuses on studying observable actions and responses to external stimuli, rather than internal thoughts or emotions, as part of the behaviorism movement. This approach, popularized in the early 20th century, has shaped fields like therapy, education, and animal training by emphasizing environmental influences and conditioning. In modern contexts, it can also describe methods in technology and marketing that rely on predictable human responses to rewards and punishments.
