An Evaluation of Sequential Meal Presentation with Picky Eaters.

Results of previous research evaluating sequential presentation of nonpreferred (NP) and high-preferred (HP) foods have been mixed, and little is known about how preferences for foods and the manner in which they are presented impact consumption. In many households, NP and HP foods are presented together on the same plate (total meal presentation). This was true for the participants included in this study; thus, total meal presentation served as a baseline against which to compare the effects of an appetizer presentation method and subsequently sequential presentation (differential reinforcement).

The effects of modeling contingencies in the treatment of food selectivity in children with autism.

The current study investigated the effectiveness of stating and modeling contingencies in increasing food consumption for two children with food selectivity. Results suggested that stating and modeling a differential reinforcement (DR) contingency for food consumption was effective in increasing consumption of two target foods for one child, and stating and modeling a DR plus nonremoval of the spoon contingency was effective in increasing consumption of the remaining food for the first child and all target foods for the second child.
