Document Summary

Q: suppose that, after an animal has been classically conditioned to salivate to a tone, a flash of light is paired with the tone. After several light-tone pairings, the animal salivates to the light. Response-reinforcement (not stimulus-response!!) bond is critical . Notion of operants responses that get reinforced are more likely to occur: take small steps to get the behaviour going. Reinforce every correct response: fixed ratio (fr) Post reinforcement pause (staircase: e. g. , fr5 reinforce every 5th correct response, fr1 = cr, variable ratio (vr) On average, reinforce every nth correct response. Resistant to extinction: e. g. , vr5 might include: 4,4,7: in each case, the mean is 5. Reinforce first correct response after a certain time has elapsed. Post reinforcement pause curved (waves: e. g. , fi for 1 minute reinforce first correct response after 1, fixed interval (fi) minute, variable interval (vi) Reinforce first correct responses after a certain time has elapsed, on the average: e. g. , vi for 1 minute might include:
