Most research on stimulus preference and reinforcer assessment involves a preference assessment that is followed by a reinforcer assessment. Typically, the most and least preferred stimuli are tested as reinforcers. In the current study, we first quantified the reinforcing efficacies of six food items and then assessed relative preference for each…

Two studies were conducted that examined the preference of a student diagnosed with a brain injury. In Study 1, a preference assessment was followed by a three-choice concurrent operants reinforcer assessment. Two choices resulted in access to preferred activities for completing work, and a third choice resulted in access to nothing (i.e., no…

The study evaluated the effects of a time-efficient reinforcer assessment package with three preschoolers with autism. Systematic assessment of children's reinforcers for correct responding virtually eliminated nontargeted maladaptive behaviors, and yielded expected improvements in accuracy. (Author/DB)

A study evaluated the utility of a five-minute stimulus preference assessment for 20 individuals with developmental disabilities. The brief assessment identified stimuli that functioned as reinforcers for a simple operant response and identified preferred stimuli that were differentially effective as reinforcers. This assessment was associated…

A study evaluated the accuracy of a reinforcer survey by comparing the survey results to the results of subsequent reinforcer assessment for 20 children with attention deficit disorders using a concurrent-operants arrangement to assess relative reinforcer preference. Total accuracy for the survey was determined to be approximately 57 percent.…

Educational interventions based on the principles of behavior analysis are highly effective for establishing skills in young children with autism. As a first step in program development, the child's current skill level is determined by evaluating performance on tasks drawn from a preestablished curriculum. However, few specific guidelines have…

This study compared three methods of stimulus preference assessment for four verbal children (ages six to nine) with attention deficit hyperactivity disorder, specifically evaluating the utility of a verbal choice procedure for assessing relative reinforcer value. Verbal and pictorial stimulus-choice assessments identified high- and low-preference…

In the current study, nursing home staff were taught to administer functional analyses to determine the variables maintaining aggression by an elder with dementia. The results indicated that aggression was evoked during bathroom routines and that escape maintained aggression. Staff then reduced aggression to near-zero levels with noncontingent…

A study of three adults with profound mental retardation investigated the effects of using systematically assessed preferred stimuli versus staff opinion-based preferred stimuli on increasing happiness indices. Preferred stimuli based on preference assessments were more consistently accompanied by increased happiness indices than were preferred…

A functional analysis involving antecedent events was conducted with four students identified as having behavior problems. Off-task behavior was measured while task difficulty and level of adult attention was manipulated during analog sessions. Results revealed higher rates of off-task behavior during difficult tasks and improved behavior when…

Functional analyses of problem behaviors were performed with three individuals with severe intellectual disabilities. Results indicated that the problem behaviors were maintained either when the behavior resulted in escape from difficult tasks or when the behavior resulted in access to preferred items. Training in functionally equivalent…
