Differential Reinforcement

Question 1

Differential Reinforcement of Other Behaviors (DRO)

Answer 1

Purpose- Reduce interfering behaviors to zero occurrences by increasing the amount of time between occurrences.

Definition- Reinforcement is provided when the learner is NOT engaging in the interfering behavior.

Example- Student receives a reinforcer when he goes without hitting himself for five minutes.

Question 2

Differential Reinforcement of Low Rates or Behavior (DRL)

Answer 2

Definition- Reinforcement is provided if the learner engagement in the interfering behavior was at or below a predetermined criterion.

Example- Student receives a reinforcer when she uses the water fountain 5 or less times a day during the school day.

Question 3

Differential Reinforcement of Alternative Behavior (DRA)

Answer 3

Definition- Reinforcement is provided when the learner is engaging in a specific desired behavior other than the interfering behavior.

Example- Student receives a reinforcer when he raises his hand to answer the teacher’s question.

Question 4

Differential Reinforcement of Incompatible Behavior (DRI)

Answer 4
