Background: The implicit learning deficit hypothesis claims that impaired implicit learning underlies deficits in social-communicative abilities associated with developmental language disorder (DLD). However, previous research testing this hypothesis revealed inconsistent results and largely used process-impure sequential learning tasks. Aims:…

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…

The purpose of the analyses described in this report was to evaluate both the effects of two contrasting approaches to parent-provided child learning opportunities and the direct and indirect effects on both proximal and distal parent social-affective behavior and verbal appraisals. The participants were 71 children with significant developmental…

This study investigated the effects of varying opportunities to respond when using a behavior management program with three elementary school students with developmental disabilities in a small group special education setting. These students exhibited both academic and behavioral difficulties. With the implementation of Class-Wide Function-Related…

The Good Behavior Game (GBG) is a classroom management system that employs an interdependent group contingency, whereby students work as a team to win the game. Although previous anecdotal data have suggested that this arrangement may promote prosocial behavior, teachers may have concerns about its fairness and potential to evoke negative peer…

Although functional analysis (FA) remains the standard for identifying the function of problem behavior for students with developmental disabilities, traditional FA procedures are typically costly in terms of time, resources, and perceived risks. Preliminary research suggests that trial-based FA may be a less costly alternative. The purpose 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…

Effects of a movement suppression time-out, which involved punishing any movements or verbalization while a client is in the time-out area, were evaluated in four experiments. The procedure produced a larger reduction in the target behavior in all three children and effectiveness was explained in terms of suppression of self-stimulation during…

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…

After finding that self-injurious behavior in two young males with developmental disabilities was negatively reinforced by escape from instructional activities, an intervention provided noncontingent escape on a fixed schedule and differential negative reinforcement of other behavior. Provision of escape, even when noncontingent, resulted in…

The article describes a program in which paraprofessionals taught behavior modification contingency management techniques to parents of developmentally disabled children who lived beyond the range of the community residential facility. (DLS)

Three studies investigated environmental correlates of self-injurious behavior in seven developmentally disabled children and adolescents which were then later used for treatment. Correlates investigated included positive reinforcement, negative reinforcement, automatic reinforcement, and control. "Escape extinction" was successfully…

The self-injurious behaviors of nine subjects with developmental disabilities were observed in settings in which play materials, experimenter demands, or social attention were systematically varied. Although there was much between-subject and within-subject variability, higher levels of self-injury were consistently associated with a specific…
