Instruction in auditory-visual conditional discriminations for young children with autism spectrum disorder is typically based on either a conditional-only or a simple-conditional method. In this study, we evaluated a modified simple-conditional method in which we removed the steps for which visual comparisons were presented in isolation. We…

Prompts are commonly used during discrete trial teaching for individuals diagnosed with autism spectrum disorder (ASD). Three commonly used prompting systems include constant time delay, most-to-least prompting, and flexible prompt fading. Most of the research demonstrating the effectiveness of these three prompting strategies have been completed…

Research on tact acquisition by children with autism spectrum disorder (ASD) has often focused on teaching participants to tact visual stimuli. It is important to evaluate procedures for teaching tacts of nonvisual stimuli (e.g., olfactory, tactile). The purpose of the current study was to extend the literature on secondary target instruction and…

Research on stimulus-stimulus pairing to induce novel vocalizations in nonverbal children has typically employed response-independent pairing (RIP) procedures to condition speech sounds as reinforcers. The purpose of the present study was to evaluate the effects of a response-contingent pairing (RCP) procedure on the vocalizations of three…

Children with autism spectrum disorder (ASD) often have difficulty inferring the private events of others, including private verbal behavior (e.g., thoughts), private emotional responses, and private establishing operations, often referred to as "perspective taking" by the general psychology community. Children with ASD also have…

The current investigation evaluated repertoires that may be related to performance on auditory-to-visual conditional discrimination training with 9 students who had been diagnosed with autism spectrum disorder. The skills included in the assessment were matching, imitation, scanning, an auditory discrimination, and a visual discrimination. The…

Adults with autism spectrum disorder (ASD), who were interested in working as behavior technicians for young children with autism, participated in 2 experiments. Participants included 5 adults with Asperger syndrome or pervasive developmental disorder not otherwise specified, 19 to 23 years old, and 11 children with autism, 3 to 7 years old. In…

We conducted a modified paired-choice preference assessment and used a multielement design to examine the effects of noncontingent access to high- and low-preference music on vocal stereotypy exhibited by children with autism. For 3 of the 4 participants, high-preference music (a) produced lower levels of vocal stereotypy than low-preference music…

We tested the effects of an observational intervention (Greer & Singer-Dudek, 2008) on establishing children's books as conditioned reinforcers using a delayed multiple baseline design. Three preschool students with mild language and developmental delays served as the participants. Prior to the intervention, books did not function as reinforcers…

A study examined the effects of a high-probability procedure on the compliance with medical procedures of a toddler with developmental delays and self-injurious behavior. Compliance to low-probability requests occurred more frequently following compliance to high-probability requests, suggesting that this procedure may be useful across different…

A study examined sensitivity to reinforcement in two boys (ages 7-10) with attention deficit hyperactivity using the matching law and evaluated effects of methylphenidate. In the medicated condition, the matching function for both subjects resulted in higher asymptotic values, indicating an overall elevation of behavior rate under these…

A study found verbal reprimands, delivered contingent upon eating prohibited foods, were sufficient to decease the food stealing of a girl (age 14) with Prader-Willi syndrome. Warning stimuli were then successfully used to help her discriminate between permitted/prohibited foods during sessions in which food stealing was not directly observed.…
