Document Summary
Week 7 chapter 15: respondent conditioning and operant conditioning together. Respondent conditioning: if a neutral stimulus is followed closely in time by an unconditioned stimulus (us), which elicits an unconditioned response (ur), then the previously neutral stimulus will also elicit the ur in the future. Responses: are referred to as reflexive (through pairing with a stimulus) or involuntary behavior; said to be elicited by prior stimuli. Reinforcers: pairing of ns and us comes before the response; result of conditioning is that the response is more likely to occur to the cs (previously the ns) Extinction: presenting the cs while withholding the us the cs gradually loses its ability of eliciting the cr. Operant conditioning: the modification of behavior by its consequences. Behavior is an operant behavior that is controlled by consequences and said to be emitted by an individual. Responses: voluntary behavior that is elicited through conditioning.
