In the current study, the utility of paired-stimulus preference assessment in identifying stimulus preferences was evaluated with adults with schizophrenia. In addition, the effects of two establishing operations (i.e., deprivation, satiation) on stimulus selection during paired-stimulus preference assessment were evaluated. Specifically, paired-stimulus preference assessments were conducted across conditions of (a) control, in which participants were given free access to premeasured portions of each of four stimuli prior to the preference assessment at five scheduled times; (b) deprivation, in which participants were given free access to premeasured portions of three of the four stimuli at five scheduled times and were deprived of one of the four stimuli for 48 hr prior to the preference assessment; and (c) satiation, in which participants were given no access to three of the four stimuli at five scheduled times and were free access to one of the four stimuli for 15 min prior to the preference assessment. The paired-stimulus preference assessment resulted in preference hierarchies for 3 of the 4 participants and identified two highly preferred stimuli for 1 of the 4 participants. Overall, across participants, deprivation resulted in increased selection of stimuli, and satiation resulted in decreased selection of stimuli, relative to control. However, some variation across stimuli and participants occurred in each condition. The implications of the current findings are discussed.
