ABA Fundamentals

Descriptive analysis of eating regulation in obese and nonobese children.

Epstein et al. (1976) · Journal of applied behavior analysis 1976
★ The Verdict

Having kids place utensils down between bites reliably slows eating but can also cut total food eaten.

✓ Read this if BCBAs working on mealtime pace with children in home or clinic settings.
✗ Skip if Clinicians whose main goal is to increase overall caloric intake.

01Research in Context

01

What this study did

Researchers watched children eat during normal meals. They compared kids labeled obese with kids who were not.

Each child got the same simple rule: put the fork or spoon down after every bite. The team counted bites per minute and total food eaten.

The study used a multiple-baseline design across children. This means the rule started at different times to show the rule, not luck, caused any change.

02

What they found

Every child slowed their bite rate when they set the utensil down.

Yet the slower pace also cut the total amount of food eaten. Some kids drank more or talked more, but eating still dropped.

03

How this fits with other research

Feldman et al. (1999) later used the same slow-bite idea with an adolescent who had esophageal stricture. They added praise and framed slower eating as safety, not weight control.

Douma et al. (2006) tested the rule with an adult who had bulimia. Ten-second pauses erased her urge to vomit, showing the trick works across ages and problems.

Capio et al. (2013) shifted the focus from bite speed to bite chewing. Their prompt “chew it up” plus praise boosted chews per bite in kids with feeding disorders, proving you can shape different parts of the same response.

04

Why it matters

If you want a child to eat more slowly, simply teach “fork down, pause, pick up.” The move is easy to model and prompt. Just know it may also lower total intake, so weigh this if the child is underweight or already eats small amounts. Pair the rule with praise and track both bite rate and grams eaten to be sure the change helps your client’s goals.

Model putting the spoon on the table after each bite and give praise for the pause; count bites per minute and weigh the plate to watch both speed and intake.

03Original abstract

Bite rate, sip rate, and concurrent activities of six 7-yr-old children, three obese and three nonobese, were observed at lunchtime over a six-month period. A procedure for decreasing bite rate, putting eating utensils down between bites, was implemented in a multiple-baseline across-subjects design. Sip rates and concurrent activities were observed to assess behavioral covariations. In addition, bite rate and amount of food completed were computed over six food categories to analyze food preferences. Results indicated the control of bite rate acorss all subjects, with a significant reduction in amount of food consumed. Correlations between the response classes indicated they were at least partially independent. Differences in eating behavior of obese and nonobese subjects were observed for breadstuffs and milk drinking.
