Document Summary

Response-reinforcement bond is critical responses that get reinforced are more likely to occur. Schedules of reinforcement: continuous reinforcement (cr) -> reinforce every correct response, fixed ratio (fr) -> reinforce every nth correct response e. g. fr5 -> reinforce every 5th correct response, fr1 = cr. Would typically start with cr and move to fr at increasing intervals: variable ratio (vr) -> on average reinforce every nth correct response e. g. vr 5 might include, 3, 7, 5, 13, 1, 1, 4,4,7. > each case mean = 5: fixed interval (fi) -> reinforce first correct response after a certain. Time has elapsed e. g. fi 1 minute, reinforce first correct response after 1 minute: variable interval (vi) -> reinforce first correct response after a certain. Time has elapsed, on average. e. g. vi 1 min. might include: 2 min, 30 sec, 30 sec, 90 sec, 45 sec, 45 sec, 15 sec, 1 min, 105 sec. > in each case, mean = 1 min.
