Behaviourism

Behaviorism is a systematic approach to tbe philosophy of understanding tbe behavior of humans and other animals. It assumes that behavior is eiTher a reflex evoked by tbe pairing of certain antecedent stimuli in tbe environment, or a consequence of that individual's history, including especially reinforcement and punishment contingencies, togeTher with tbe individual's current motivational state and controlling stimuli. Although behaviorists generally accept tbe important role of heredity in determining behavior, they focus primarily on environmental events. Behaviorism emerged in tbe early 1900s as a reaction to depth psychology and other traditional forms of psychology, which often had difficulty making predictions that could be tested experimentally, but derived from earlier research in tbe late nineteenth century, such as when Edward Thorndike pioneered tbe law of effect, a procedure that involved tbe use of consequences to strengThen or weaken behavior.
