Displacement of leisure reinforcers by food during preference assessments.
Identification of reinforcers for individuals with developmental disabilities is often based on the outcome of preference assessments in which participants make selections from among a variety of items. We determined the extent to which individuals might show a general preference for food items over leisure items during such assessments and whether leisure items that are "displaced" by food ite...
متن کاملEvaluation of the rate of problem behavior maintained by different reinforcers across preference assessments.
The rates of problem behavior maintained by different reinforcers were evaluated across 3 preference assessment formats (i.e., paired stimulus, multiple-stimulus without replacement, and free operant). The experimenter administered each assessment format 5 times in a random order for 7 children with developmental disabilities whose problem behavior was maintained by attention, tangible items, o...
متن کاملPreference reversals with food and water reinforcers in rats.
Rats were given a choice between a smaller, immediately available reward and a larger reward available after a delay. In one phase, the reward was food and in another phase, the reward was water. Constant delays were added between the choice presentation and the delivery of the reward alternatives. As the time between choice and reward delivery increased from 0 to 25 s, all rats (except one in ...
متن کاملEvidence for the rapid construction of preference during utility assessments
Subjects often construct preferences during the elicitation process. This could have implications for the processes automated utility assessments use to find indifference points. In particular, if subjects frequently shift preferences during elicitation processes, then reversible and irreversible procedures might reach different results. We analyzed series of choices made by two groups of subje...
متن کاملTwo measures of preference during forced-choice assessments.
A forced-choice preference assessment was conducted in which two dependent measures were used to select preferred stimuli: (a) approach responding and (b) latency to the first aberrant response. Stimuli identified as preferred based on both dependent measures were then evaluated during treatment. The results suggested that latency may be a useful measure in the selection of preferred stimuli du...
