We evaluated a method for teaching children with autism spectrum disorder to respond to tactile stimulation of multiple body parts. Various objects (e.g., hairbrush) produced the sensations (e.g., prickly). In a multiple baseline design across participants, participants learned 9 sensation body part tacts and the evaluation concluded with tests of…

Stereotypy has been classified as repetitive behavior that does not serve any apparent function. Two procedures that have been found to reduce rates of vocal stereotypy effectively are response interruption and redirection (RIRD) and noncontingent access to matched stimulation (MS). The purpose of the current study was to evaluate the effects of…

We evaluated the effects of 3 types of noncontingent auditory stimulation (music, white noise, recordings of vocal stereotypy) on 2 children with autism who engaged in high rates of vocal stereotypy. For both participants, the music condition was the most effective in decreasing vocal stereotypy to near-zero levels, resulted in the highest parent…

This experiment investigated social referencing as a form of discriminative learning in which maternal facial expressions signaled the consequences of the infant's behavior in an ambiguous context. Eleven 4- and 5-month-old infants and their mothers participated in a discrimination-training procedure using an ABAB design. Different consequences…

Every article on stimulus equivalence or derived stimulus relations published in the "Journal of Applied Behavior Analysis" was evaluated in terms of characteristics that are relevant to the development of applied technologies: the type of participants, settings, procedure automated vs. tabletop), stimuli, and stimulus sensory modality; types of…

The effects of preferred stimulation on the vocal stereotypy of 2 individuals were evaluated in two experiments. The results of Experiment 1 showed that (a) the vocal stereotypy of both participants persisted in the absence of social consequences, (b) 1 participant manipulated toys that did and did not produce auditory stimulation, but only…

The effects of noncontingent matched stimulation (NMS) and response blocking on a boy's stereotypic behavior were evaluated using a multiple schedule that contained three 15-min components (preintervention, intervention, and postintervention). Results showed that stereotypy was always higher after response blocking than before response blocking…

The present study investigated the effects of differential negative reinforcement of other behavior (DNRO) on problem behavior evoked by music in a 7-year-old child with pervasive developmental disorder. Following an auditory stimulus assessment, DNRO was used to reduce problem behavior to near-zero levels. Results are discussed in terms of…

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…

Conditions associated with the maintenance of hand mouthing were studied in 3 experiments with 12 adults with profound mental retardation. Functional analysis of hand mouthing, reinforcers, and preference for hand-toy versus mouth-toy contact were assessed. Hand stimulation was the predominant reinforcer for all participants. (SW)

A detailed hypothesis of the acquisition and maintenance of self-stimulatory behavior is offered, proposing that such behaviors are operant responses whose reinforcers are automatically produced perceptual consequences. Related concepts are discussed, and support for the hypothesis from the areas of sensory reinforcement and sensory deprivation is…

This review of research discusses how children with autism may acquire equivalence classes after learning to supply a common oral name to each stimulus in a potential class. A proposed methodology for researching referent naming and class formation, analysis of stimulus classes, and generalization is offered. (CR)

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…
