Document Summary

Shape professor response: notion of operants, response reinforcement bond is critical, responses that get reinforced are more likely to occur. Fixed ratio (fr: give certain amount. Variable ratio (vr: on average, reinforce, every nth correct response. Fixed interval (fi: reinforce first correct response after a certain time has elapsed, eg. Reinforce first correct response after 1 minute. Variable interval (vi: reinforce first correct response after a certain time has elapsed, on the average. Experience with extinction, maintains responding because reinforcement is unpredictable. Partial better than continuous: vr or vi are most resistant to extinction. Cognitive approach: learning is not mechanical stamping in process. Involves formation of cognitions, the internal processing of information (thoughts, beliefs: kohler insight, tolman cognitive maps, traditional stimulus response approach can"t explain very well. Classical conditioning: unconditioned stimulus (shock) gives fear/pain (unconditioned response) Operant conditioning: termination of light acts as negative reinforce for jump response, nice but exactly what is this conditioned fear response, organism learns contingency.
