Differential Reinforcement (DRA / DRI / DRO)

Differential reinforcement combines reinforcement and extinction. You heavily reward a good alternative behaviour while completely ignoring the problem behaviour. Common variations include:

• DRA (Alternative): Reinforces any appropriate replacement behaviour.
• DRI (Incompatible): Reinforces a behaviour that physically cannot happen at the same time as the problem behaviour.
• DRO (Other): Delivers reinforcement simply for the absence of the problem behaviour over a set time period.
