The effects of establishing operations on preference assessment outcomes.
Journal of Applied Behavior Analysis,
33, 85-88.
Preference assessments were conducted for 4 individuals with
developmental disabilities across conditions of (a) control,
allowing equal access to all stimuli prior to the preference
assessment; (b) deprivation, allowing no access to one stimulus
for 48 hr prior to the assessment; and (c) satiation, allowing
free access to one stimulus for 10 min immediately prior to the
assessment. Deprivation resulted in increased preference, whereas
satiation resulted in decreased preference compared to control
conditions.
