CH 6- LEARNING Learning- a process that results in a relatively consistent change in behavior or behavior potential, based on experience Classical conditioning: a basic form of learning where one stimulus or even predicts the occurrence of another stimulus or event- association between stimuli o UCS- learning not necessary condition for stimulus to control behavior o UCR- behavior elicited by UCS o CS- power to elicit behavior conditioned on its association with UCS o CR- whatever response the conditioned stimulus elicits as a product of learning extinction- when CR no longer appears in the presence of CS- happens because of the absence of the UCS Stimulus generalization- automatic extension of responding to stimuli (like the CS) that have never been paired with the UCS stimulus discrimination- organism learns to respond differently to stimuli that are distinct from the CS or to some dimension o with more discrimination training, the subject will not respond to dissimilar stimuli o need a balance between 2 classical conditioning of emotional responses and drug tolerance o emotional responses can’t explain why you have a strong reaction/preference about something fear conditioning pairs a neutral stimulus with something naturally fear provoking o drug tolerance can develop when an individual anticipates the pharmacological action of a drug drug (UCS) brings about physiological responses to which the body counteracts (UCR)to reach homeostasis in settings ordinarily associated with drug use (CS) body physically prepares its self(CR) for drugs expected effects Thorndike’s Law of Effect o learning was an association between stimuli in the situation and a response that an animal learned to make o a response that is followed by satisfying consequences becomes more probable and a response that is followed by dissatisfying consequences becomes less probable Skinners analytic approach- o operant conditioning- manipulated the consequences of an organisms behavior in order to see what effect they had on subsequent behavior reinforcement- INCREASES probability response occurs o Positive reinforcement- behavior followed by delivery of an appetitive stimulus o negative reinforcement- behavior followed by removal of an aversive stimulus escape- response will allow them to escape aversive stimulus avoidance- response will allow them to avoid aversive stimulus before they begin punishment- decreases probability of a response over time o positive punishment- behavior followed by delivery of aversive stimulus o negative punishment- behavior followed by removal of appetitive stimulus reinforcers- o primary- reinforcing properties biologically determined o conditioned- neutral stimuli have become associated with primary reinforcers schedules of reinforcement
