Developing proper mealtime behaviors of the institutionalized retarded.

Hake et al. (1972) worked with twelve people living in a state institution. All had serious mealtime problems like grabbing food or eating with their hands.

Staff used a short teaching plan. They showed the right way to sit, use a fork, and wipe lips. After each lesson they gave praise and small treats. They also used a brief timeout for any mess. The team kept checking if the good manners lasted.

Every person learned to eat like a typical restaurant guest. They used forks, kept clothes clean, and stayed seated.

The skills stayed high for weeks with almost no timeout needed. Staff said the dining room felt calm and normal.

Bailey et al. (1970) had already shown that timeout alone can stop food stealing and finger eating. F et al. added teaching first, then timeout only if needed. The mix cut problem acts faster and kept them gone longer.

Sarber et al. (1983) and Sanders et al. (1989) later used the same teach-praise method for grocery lists and cooking. Their adults with developmental disabilities also kept the skills, showing the package works for bigger meal tasks.

Zhou et al. (2023) moved the idea to autistic children. Instead of manners, they taught kids to wait and not steal food. Self-control training reached zero stealing, just as F et al. reached zero mess.

You can copy this two-step plan in any group home or classroom. First, model and rehearse the right move. Then give quick praise and only use timeout for rare slips. The whole package takes a few days and the change sticks, turning loud meals into calm ones.
