Differential reinforcement means reinforcing some behavior while withholding reinforcement for other behavior. It is a common way to reduce problem behavior.
Example
A learner calls out during group time. The plan reinforces raising a hand and does not reinforce calling out.
Key points
- DRA (alternative behavior): reinforce a specific appropriate alternative to the problem behavior.
- DRI (incompatible behavior): reinforce a behavior that cannot happen at the same time as the problem behavior, such as keeping hands in pockets instead of hitting.
- DRO (other behavior): reinforce when the problem behavior has not occurred for a set time.
- DRL (low rates): reinforce when the behavior stays at or below a set rate.
Exam tip
DRA and DRI teach a specific behavior. DRO reinforces the absence of the problem behavior. DRL reinforces lower rates rather than none.
Common mistake
Reinforcing the replacement behavior inconsistently, so the problem behavior still pays off more.
Quick check
In DRA, what gets reinforced? An alternative, appropriate behavior.
