An evaluation of simultaneous and sequential presentation of preferred and nonpreferred food to treat food selectivity.
Journal of Applied Behavior Analysis,
35, 259-270.
In the current investigation, we compared two methods of food
presentation (simultaneous vs. sequential) to increase
consumption of nonpreferred food for 3 children with food
selectivity. In the simultaneous condition, preferred foods were
presented at the same time as nonpreferred food (e.g., a piece of
broccoli was presented on a chip). In the sequential condition,
acceptance of the nonpreferred food resulted in presentation of
the preferred food. Increases in consumption occurred immediately
during the simultaneous condition for 2 of the 3 participants.
For 1 participant, increases in consumption occurred in the
simultaneous condition relative to the sequential condition, but
only after physical guidance and re-presentation were added to
treatment. Finally, consumption increased for 1 participant in
the sequential condition, but only after several sessions. These
results are discussed in terms of possible mechanisms that may
alter preferences for food (i.e., establishing operations,
flavor–flavor conditioning).
