Document Summary

Differential reinforcement: note: can also be used to reinforce specific high rates of behaviour too. Schedules of reinforcement designed to decrease or eliminate behaviours. But we focus here on using it to reduce behaviour: differential reinforcement of low rates (drl, differential reinforcement of zero responding (dro, differential reinforcement of incompatible responding (dri, differential reinforcement of alternative behaviour (dra) Reinforcing only low rates of responding: reinforcer is presented only if behaviour occurs at the low rate. Limited responding drl: max. number of allowable responses during an interval for the reinforcer to occur, useful when: After that interval, the behaviour: then the (cid:498)no behaviour interval(cid:499) begins again. Behaviour ends up spaced out over time. Similar to drl-lr: use this when you want to lower a behaviour but not will be rewarded when it occurs eliminate it. In this case, we reinforce when there is adequate pause between occurrences.
