A comparison of simultaneous versus sequential presentation of novel foods in the treatment of food selectivity



The present study extended the literature on feeding disorders by conducting a comparison of sequential and simultaneous food presentation in the treatment of food selectivity. In the simultaneous condition, a highly preferred food was presented in the same bite with a non-preferred food (NPF), and during the sequential condition, a highly preferred food was delivered as a consequence for acceptance and consumption of NPFs. Generalization and maintenance of food consumption was assessed. Although results for two participants indicated that both presentation methods produced an increase in acceptance and consumption of NPFs when combined with an escape extinction procedure, anecdotal observations suggested that participants may have had a preference for eating foods in a sequential fashion.
