In which condition does the therapist provide an item following problem behavior?

The tangible condition is characterized by the therapist providing a desirable item or access to a preferred activity in response to problem behavior. This setup is used to assess whether the individual engages in problematic actions to gain access to tangible rewards. For example, when an individual exhibits aggressive or disruptive behavior, if they receive the desired item immediately afterward, it reinforces that behavior.

In contrast, in other conditions, different motivations are examined. The alone condition typically assesses behavior in the absence of social interaction, while the control condition generally involves a scenario where positive reinforcement is available without contingencies for problem behavior, and the escape condition focuses on challenging behaviors exhibited to escape an aversive demand or situation. Thus, the tangible condition is distinct because the focus is specifically on gaining access to physical items or activities as a result of maladaptive behaviors.
