A BCBA described a procedure where a child is guided to sit in a chair with a booster seat for 2 minutes after an unwanted behavior. This most closely exemplifies which time-out type?

• A. exclusion time-out
• B. nonexclusion time-out, select space time-out
• C. planned ignoring
• D. response cost

Answer: (B)

The scenario is using a nonexclusion time-out with a specific time-out space. After the undesired behavior, the child remains in the room but is placed in a designated chair (the booster seat) for a short period. This blocks access to reinforcement during the timeout while the child stays in the same environment, which is the essence of nonexclusion time-out and the “select space” variant when a particular space within the room is used as the time-out area.

Why the other options don’t fit as well: removing the child from the room would be an exclusion time-out, which isn’t happening here since the child stays in the room. Planned ignoring involves not attending to the behavior but doesn’t place the child in a time-out location. A time-out here isn’t about losing a separate privilege or token (response cost), but about the time-limited placement in a nonreinforcing space within the room.
