Document Summary
The three procedures are dra, dro, and drl. This behavioural procedure is used to increase the frequency of a desirable behaviour and to decrease the frequency of undesirable behaviours. The desirable behaviour is reinforced each time it occurs , you reinforce the behaviours that you want to keep and you extinct the behaviours that you wish to diminish. In the case of mrs. williams she was much more likely to complain when a nurse was present and this got her the nurse"s attention. When she said positive things she got attention, but she didn"t get attention when she said negative things. Dra can be used to strengthen and to maintain behaviours such as shaping or prompting. If adam read the exercises correctly he would avoid having to perform the tedious exercises. Dri differential reinforcement of an incompatible behaviour alternative behaviour is physically incompatible with the problem behaviour.
