Brief experimental analysis (BEA) is a useful tool for quickly evaluating intervention strategies for individuals with academic deficits and minor behavior problems. However, there is a lack of research investigating BEA for intervention strategies with individuals who emit severe problem behavior to avoid academic demands. For the current study,…

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 current study examined the effects of task interspersal on the performance of matching-to-sample tasks by three children with autism. A pre-baseline assessed each child's mastery level of a large body of matching stimuli. These matching tasks included matching identical and non-identical animals, numbers, letters, and shapes. Through this…

Previous researchers have used stimulus preference assessment (SPA) methods to identify salient reinforcers for individuals with developmental disabilities including tangible, leisure, edible and olfactory stimuli. In the present study, SPA procedures were used to identify potential auditory reinforcers and determine the reinforcement value of…

This study examined the utility of a paired-choice preference assessment in predicting reinforcer efficacy for a 13-month old with a history of prenatal drug exposure. First, two paired-choice assessments were conducted one week apart, using the same items. A high level of correspondence between the two assessments was observed. Next, a reinforcer…

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…
