Six experiments were conducted with graduate students to assess resurgence of compound (i.e., multi-step) academic responding under free operant procedures. Participants learned two different interobserver agreement (IOA) methods -- compound behaviors -- through instructional phases before beginning the experimental phases. Each experiment…

Interventions related to differential reinforcement (DR) are among the most frequently used within the field of applied behavior analysis (ABA). However, certain conditions can inhibit the level at which effects of these interventions maintain upon treatment challenges or generalize across contexts. This can result in the relapse, or recurrence of…

Children with autism spectrum disorder (ASD) often show language delays. Their limited communication skill may lead them to engage in the same disruptive behavior that previously got them what they wanted. Verbal behavior (VB), specifically mand training (MT), is one of the early language intervention strategies used to target language development…

For children with developmental or language delays, mand interventions have been identified as an integral part of educational programming (e.g., Greer & Ross, 2008; Shafer, 1994; Sundberg & Michael, 2001). Mands, which are the most elementary forms of verbal behavior, allow individuals to begin to contact social contractual contingencies;…

In Experiment 1, I conducted a functional analysis of student rate of learning with and without a peer-yoked contingency for 12 students in Kindergarten through 2nd grade in order to determine if they had conditioned reinforcement for collaboration. Using an ABAB reversal design, I compared rate of learning as measured by learn units to criterion…

The purpose of this study was to examine the effects of PECS phase III application training on independent mands in young children with autism. Participants were five children with autism ranging from ages 2 to 4 years old. A multiple baseline across participants was used to evaluate acquisition of independent correct mands across baseline and…

In the following paper, two experiments are reported based on the relation between adult approvals as conditioned reinforcers and the number of vocal verbal operants, specifically tacts, mands, wh questions, sequelics, and conversational units emitted by children diagnosed with developmental disabilities. In Experiment I, following an experimental…

A primary deficit seen in many children with autism, particularly those with limited verbal repertoires, is repetitive and rote verbal behavior. This type of repetitive or rote verbal behavior can be stigmatizing and may severely limit access to primary reinforcers. Therefore, it may be beneficial to attempt to increase response variability in…

This study examined the effects of Dolphin-Assisted Therapy (DAT) as a reinforcer for verbal operant production in children with Autism Spectrum Disorder. Three children who attended a dolphin therapy program participated in this single subject research study. Baseline data was collected for each child via a video tape provided by parents and…
