On the Correspondence Between Preference Assessment Outcomes and Progressive-Ratio Schedule Assessments of Stimulus Value (1 Unit)
Abstract: The current study examined whether stimuli of different preference levels would be associated with different amounts of work maintained by the stimuli, as determined through progressiveratio schedule break points. Using a paired-choice preference assessment, stimuli were classified as high, moderate, or low preference for 4 individuals with developmental disabilities. The stimuli were then tested three times each using a progressive-ratio schedule (step size of 1; the break-point criterion was 1 min). In 10 of 12 possible comparisons, higher preference stimuli produced larger break points than did lower preference stimuli.
