Abstract

Abstract

This experiment evaluated the effects of noncontingent and contingent access on relative preference for items identified through a series of preference assessments. Four typically developing children participated in multiple stimulus without replacement preference assessments to establish a relative hierarchy of preferred activities. Following the MSWO, the participants were exposed to contingent access or noncontingent access conditions that were separated by preference assessments to assess stability of the preference hierarchy. Results were discussed in terms of preference, preference shifts, and the response deprivation hypothesis.
