Differential reinforcement involves reinforcement of a desired behavior while placing an undesirable behavior or target behavior on extinction through withholding reinforcement.
Some things to note:
- DRI & DRA procedures both require an identified replacement behavior. The main difference is that with DRI, you cannot perform the undesired and desired behavior at the same time, whereas with DRA, it's possible to do both.
- When identifying a suitable replacement behavior, it's best choose a behavior that meets the same need or is functionally equivalent. If a kid falls out their seat in class to get the teacher's attention, then a replacement behavior would be to remain in their seat and raise their hand.
- One of the downfalls of DRO procedures is that the individual doesn't learn a suitable, alternative behavior to meet their needs and we can actually reinforce other unwanted behaviors in the process.
