In the DRI strategy, the behaviors are characterized by:

In the DRI (Differential Reinforcement of Incompatible Behavior) strategy, the focus is on reinforcing a behavior that is incompatible with the undesired behavior. This means that the two behaviors cannot occur at the same time because they physically or functionally conflict with one another.

For example, if a child is often seen throwing objects, a DRI strategy might reinforce them for engaging in an incompatible behavior such as holding a toy gently. Since holding a toy gently and throwing something are mutually exclusive actions, the child cannot do both at the same time. By reinforcing the incompatible behavior, it reduces the likelihood of the undesired action occurring, as it's not just about discouraging the negative behavior but actively promoting an alternative behavior that cannot coexist with it.

The other options do not align with the fundamental principle of DRI. Behaviors in DRI do not require different timing or the ability to occur simultaneously; in fact, the strategy is predicated on the concept that the incompatible behaviors negate each other. Therefore, understanding that the essence of DRI revolves around behaviors that cannot happen simultaneously is key to applying this strategy effectively.
