Nonexclusion time-out is best described as the individual remaining in the setting with restricted access to reinforcement for a brief period.

• A. The individual remains in the setting but has restricted access to reinforcement for a brief period.
• B. The time-out is implemented by removing the individual from the setting.
• C. The individual leaves the setting and is separated from reinforcers.
• D. The procedure always involves a time-out room.

Answer: (A)

Nonexclusion time-out means the person stays in the setting but has restricted access to reinforcement for a brief period. The emphasis is on remaining present in the environment while reinforcement opportunities are temporarily reduced, rather than being removed from the setting. This differs from exclusion time-out, where the individual is taken out of the setting entirely. Also, a time-out room is not required for nonexclusion time-out—the procedure can occur within the usual environment using a brief, clearly defined interval. The key idea is brief reduction in access to reinforcement while the person remains in place.
