The Behaviorist Perspective

• Burrhus (B.F.) Skinner was very much influenced by Watson’s behaviorist ideas.

• Also realized that the psychology proposed by Watson had some serious shortcomings.

• In particular, a psychology based wholly on classical conditioning assumes that organisms are essentially passive – they just hang around waiting for stimuli to respond to.

• To Skinner it seemed obvious that people and animals actively engage with their environments.

• Skinner’s important insight was that an animal’s – or a person’s – behavior was determined by the consequences of its past behavior

Skinner’s Main Ideas

• Operant Condition: future behavior is determined by the consequences of past behavior

• Reinforcement: consequence that strengthens a behavior

• Punishment: consequence that weakens a behavior

• Shaping: used to teach complex behaviors (broken down into a series of simple behaviors) • Ex: used to teach tricks to animals

• Stimulus Control: learn that a certain behavior only brings reinforcement under certain conditions.
