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…

A child's early language environment, and their parents' active engagement during parent-child interactions play a vital role in facilitating the development of complex social reinforcers and the growth of their verbal behavior. Using a verbal behavioral approach, this study aimed to measure the statistical significance of changes in the quality…

This study compared the effects of listener training and tact training on the emergence of intraverbal responses in the form of foreign language equivalents of the native language. The study was based on Skinner's verbal operants with a focus on intraverbal responses. All participants received listener training and tact training after which a…

The experimenter conducted three experiments to compare incidental language acquisition of familiar and non-familiar stimuli, and asses the effects of specific pairing experiences on the emergence of bidirectional naming (BiN) for familiar and non-familiar stimuli. In Experiment I the experimenter assessed the numbers of accurate untaught listener…

In two experiments, I tested for the presence of conditioned seeing as a measureable behavior, which was measured by participants' accuracy in drawing a stimulus, and how this behavior was related to the demonstration of the naming capability. In Experiment 1, participants demonstrated a correlation between drawing responses and speaker…

This investigation evaluated the use of conditional discrimination (CD) instruction and multiple exemplar instruction (MEI) to establish derived relational responding in accordance with hierarchical frames with school aged children. The first experiment used a multiple probe design to evaluate the effectiveness of MEI to teach participants to…

The present research focuses on the possible relation between observing responses and language acquisition. In the first of three experiments, preschool aged participants with and without disabilities were presented with the opportunity to observe multiple aspects of a stimulus. A Naming experience was created in which the stimulus was presented…

Non-verbal children with autism are candidates for augmentative and alternative communication (AAC). One type of AAC device is a voice output communication aid (VOCA). The primary drawbacks of past VOCAs were their expense and portability. Newer iPod-based VOCAs alleviate these concerns. This dissertation sought to extend the iPod-based VOCA…

Behaviors that are appropriate, inappropriate, or a combination of both can be linked together in a behavior chain. When the contingencies for one response change (e.g., reinforcement is withheld for the last response in the chain; the last response is reinforced even if it occurs without the other responses in the chain) or the environmental…

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…
