Four adults diagnosed with moderate to profound mental retardation performed a manual response that was reinforced with food identified from a stimulus preference assessment. During baseline, the response was reinforced on a variable ratio (VR) schedule. Participants were then exposed to noncontingent reinforcement (NCR) plus extinction, and no‐food (i.e., extinction) conditions. A combination multielement and reversal design was used to evaluate intervention effects. For each participant, sessions were conducted both before and after the midday meal during baseline and NCR‐plus‐extinction conditions, thus capitalizing on naturally occurring states of food deprivation and satiation. Results showed that response rates were slightly higher during deprivation sessions than during satiation sessions during NCR‐plus‐extinction and VR schedules for three of the four participants. For three participants, initial NCR schedules did not reduce responding; however, subsequent NCR schedules, which were twice as dense, were effective in reducing response rates. The results are discussed in terms of the development of NCR as a reductive technology and the manipulation of establishing operations applied to the habilitation of individuals with developmental disabilities. The use of a basic experimental preparation as a method of examining decelerative interventions is also addressed. Copyright © 2000 John Wiley & Sons, Ltd.
