An ecobehavioral examination of a simple strategy for increasing mealtime language in residential facilities.

Researchers swapped cafeteria trays for family-style bowls and platters at two group homes. Adults with intellectual disabilities served themselves and passed dishes around the table. Staff recorded how often residents talked to each other during lunch and dinner.

The team used a multiple-baseline design across three behaviors: requests, comments, and overall peer talk. They kept the same staff-to-resident ratio and served the same foods as before.

Peer-directed language more than doubled once the new meal style began. Requests like “pass the potatoes” and comments such as “this tastes good” shot up immediately. Staff and residents later voted the family-style meals more enjoyable than tray service.

Decasper et al. (1977) got similar adults talking by simply leaving the dining room. Their trick was staff absence; Parsons et al. (1981) kept staff present but changed the table setup. Both tactics worked, showing you can spark conversation either way.

Raslear et al. (1992) later trained residents themselves to be peer therapists. Their gains lasted four months across the whole facility, extending the mealtime boost into everyday life.

Green et al. (1984) achieved the same jump in family talk by swapping placemats in typical restaurants. Same goal—more mealtime conversation—different population and tool, a clean conceptual replication.

You can raise social behavior tonight without extra staff or lengthy protocols. Just put serving dishes on the table and let clients pass them. It costs nothing, feels normal, and the adults in this study kept talking even after researchers stopped recording. Try it at your next group-home dinner and measure the peer words yourself.
