Past research has demonstrated that pictorial preference assessments can predict subsequent reinforcement effects for individuals with developmental disabilities only when access to the selected stimulus is provided contingent on a pictorial selection. The purpose of the present investigation was to assess more comprehensively the feasibility of…

This study examined how the amount of effort required to produce a reinforcer influenced subsequent preference for, and strength of, that reinforcer in 7 individuals with intellectual disabilities. Preference assessments identified four moderately preferred stimuli for each participant, and progressive-ratio (PR) analyses indexed reinforcer…

Factors that influence reinforcer choice have been examined in a number of applied studies (e.g., Neef, Mace, Shea, & Shade, 1992; Shore, Iwata, DeLeon, Kahng, & Smith, 1997; Tustin, 1994). However, no applied studies have evaluated the effects of postsession reinforcement on choice between concurrently available reinforcers, even though basic…

We describe a training program to teach applied behavior analysis (ABA) knowledge competencies to paraprofessional staff (N = 47) at a habilitation services agency for adults with developmental disabilities. Before and following training, staff completed assessment of knowledge tests for three content areas: basic learning principles,…

Two paradigms (rewards and verbal prompts, and timeout procedures), both making social consequences contingent upon the S's behavior and both requiring the S to practice the desired response, were used to reduce inappropriate language in a 33 year old resident of a center for the developmentally disabled. Data from the morning and afternoon…

Reviews studies involving noncontingent reinforcement (NCR) for the treatment of challenging behavior such as aggression, self-injury, and extreme tantrums in persons with developmental disabilities. A clinical guide for implementation is delineated. Among the advantages of NCR is ease of implementation. NCR appears particularly relevant for…

This study examined methods for determining how extinction should be applied to different functions of self-injurious behavior, specifically head-banging of three children with developmental disabilities. Since each subject's head-banging was maintained by different reinforcement contingencies, behavioral treatment techniques, although all based…

The role of sensory reinforcement was examined in programing multiple treatment gains in self-stimulation and spontaneous play for four developmentally disabled children (eight to ten years old). (Author/SBH)

A structure of interlocking contingencies was designed to train and support managers' provision of effective feedback to subordinates, peers, and superiors at a large state residential institution for children with developmental disabilities. The system included formal scheduling of feedback, reinforcement, and goal setting. Increased feedback…
