Improvement of retardates' mealtime behaviors by timeout procedures using multiple baseline techniques.

The team worked in a state facility dining room. All residents had intellectual disability.

They picked four mealtime problems: stealing food, eating with fingers, playing with food, and smearing it.

Timeout came in two forms. Staff either led the resident out of the room or lifted the tray for 15 seconds.

A multiple-baseline design staggered the start of timeout across the four behaviors.

Each behavior dropped sharply right after its timeout phase began.

At the same time, proper fork and spoon use went up.

No one lost weight, so the brief tray removals did not cut calories.

The gains held for the whole study period.

Hake et al. (1972) copied the setting and the target but swapped timeout for brief table-manners training. Their residents also ate like typical diners, showing you can reach the same end with teaching instead of punishment.

Zhou et al. (2023) moved the question to children with autism. They erased food stealing by teaching the kids to wait and to report their own behavior. No timeout was needed, proving self-control lessons can replace punishment.

Nishimura et al. (1987) used a similar multiple-baseline plan to slow rapid eating in adults. Prompting plus DRL cut speed, but the skill had to be re-trained in each new dining room. Together these papers show the behavior, not the tactic, drives the need for setting-specific training.

Timeout still works fast for serious mealtime disruption in group homes. Yet newer studies show you can get the same calm meals with teaching or self-management. Start with timeout if safety is at risk, then shift to skill building for a long-term, restraint-free plan.
