Answer:
Differential Reinforcement of an Other Behavior
Explanation:
Differential reinforcement of other behaviors is a procedure for decreasing problem behaviour in which reinforcement is delivered for any response other than a specific target behavior for example Jenny tends to kick people as she walks down the hall. If Jenny makes it all the way down the hall without kicking anyone her one-on-one aide lets her select a prize from the prize box. This is an example of Differential Reinforcement of an Other Behavior.
