The purpose of the present study is to systematically replicate and extend the procedures of Kern and Marder (1996) using simultaneous and sequential presentations of preferred and nonpreferred foods. Systematic fading procedures were evaluated to decrease the amount of preferred foods and increase the amount of nonpreferred foods presented. The participants were two 16-year-old males diagnosed with autism that had a history of food selectivity. In the simultaneous presentation, preferred foods were presented at the same time as nonpreferred foods. In the sequential presentation, acceptance of the nonpreferred food resulted in the presentation of the preferred food. Results were evaluated using an alternating treatments design to compare the two interventions (simultaneous presentation vs. sequential presentation). Increases in consumption occurred immediately in the simultaneous and sequential presentations for Participant 1 and in the sequential presentation for Participant 2. Additional treatment interventions were evaluated for Participant 2 in the simultaneous presentation because consumption did not increase.
