Final answer:
The three Differential Reinforcement (DR) procedures are DRO, DRI, and DRA. DRO is when reinforcement is given for not engaging in the problem behavior, DRI is when reinforcement is given for engaging in a behavior incompatible with the problem behavior, and DRA is when reinforcement is given for engaging in an alternative behavior with the same function as the problem behavior.
Step-by-step explanation:
The three differential reinforcement (DR) procedures are differential reinforcement of other behavior (DRO), differential reinforcement of incompatible behavior (DRI), and differential reinforcement of alternative behavior (DRA).
In the DRO procedure, reinforcement is delivered after a predetermined interval of time during which the problem behavior does not occur. This encourages the student to engage in other appropriate behaviors.
In the DRI procedure, reinforcement is provided when the student engages in a behavior that is incompatible with the problem behavior, thus reducing the occurrence of the problem behavior.
In the DRA procedure, reinforcement is given when the student engages in an alternative behavior that serves the same function as the problem behavior, offering a more socially acceptable way to meet their needs.
