Children with an autism spectrum disorder (ASD) may play with limited objects or toys, making it difficult for teachers to identify reinforcers to use in teaching new skills. The goal of this study was to alter children's preferences from highly preferred toys to toys that were originally less preferred using an observational pairing procedure.…

Video clips may be an effective format for presenting complex stimuli in preference assessments. In this preliminary study, we evaluated the correspondence between preference hierarchies generated from preference assessments that included either toys or videos of the toys. The top-ranked item corresponded in both assessments for 5 of the 6…

The delivery of food contingent on 10 s of consecutive toy engagement resulted in a decrease in engagement and a corresponding increase in other responses that had been previously reinforced with food. Similar effects were not observed when tokens exchangeable for the same food were delivered, suggesting that engagement was disrupted by the…

The purpose of this study was to teach empathetic responding to 4 children with autism. Instructors presented vignettes with dolls and puppets demonstrating various types of affect and used prompt delay, modeling, manual prompts, behavioral rehearsals, and reinforcement to teach participants to perform empathy responses. Increases in empathetic…

The relative reinforcing value of toys was assessed in the absence of, and immediately following, participant observation of a peer manipulating one of the materials toys. Preference assessments were used to identify preference hierarchies. Reinforcer assessments were conducted with the most high-preferred preference item, a low-preference the…

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…

Two children (ages four and five) with mild developmental delays and no appropriate toy play were trained individually on one topography for each toy. Previously reinforced topographies of toy play were then placed on extinction, resulting in the induction of untrained topographies. (Author/DB)
