Individuals with deaf-blindness and co-occurring diagnoses, such as intellectual and developmental disabilities, may experience difficulty with independence, specifically with communication. One behavior-analytic procedure that may be useful for increasing independence and teaching communication to this population is the behavior-chain…

Differential reinforcement of other behavior (DRO) is a commonly used reinforcement-based system for reducing problem behavior. DRO systems are particularly useful in that they are effective for the treatment of maladaptive behavior and can be individualized based on the needs of the learner. One possible way to enhance the effectiveness of DRO…

Background: Research with children shows that theory of mind predicts reading comprehension both concurrently and longitudinally, while research with adults shows increased print-exposure relates to theory of mind understanding. However, until now whether reading and theory of mind have a mutually reinforcing relationship in which they promote one…

Individuals with developmental disabilities (DD) are twice as likely to have obesity than non-disabled individuals. Replacing the consumption of sugar sweetened beverages (SSBs) with water has many health benefits, including weight reduction. In this study, a token reinforcement system was implemented to increase water consumption and decrease the…

Optimal integration of positive and negative outcomes during learning varies depending on an environment's reward statistics. The present study investigated the extent to which children, adolescents, and adults (N = 142 8-25 year-olds, 55% female, 42% White, 31% Asian, 17% mixed race, and 8% Black; data collected in 2021) adapt their weighting of…

Functional communication training (FCT) is an effective intervention for teaching communication responses and reducing challenging behavior. One limitation of FCT is that frequent reinforcement may be impractical or impossible in many situations. Recently, Mitteer et al. published a tutorial in the journal "AAC" that provided video…

In 2020 the Centers for Disease Control provided the public with recommendations to slow the spread of COVID-19 by wearing a mask in the community. In the current study, experimenters coached group home staff via telehealth to implement synchronous schedules of reinforcement to increase mask wearing for 5 adults with intellectual and developmental…

Misophonia is characterized by an autonomic response (e.g., increased heart rate) that is elicited by certain innocuous or repetitive sounds, and individuals with misophonia may display an extreme, overt response commonly associated with rage, hatred, and a loss of self-control. In this investigation, we used a combined respondent and operant…

Background: Due to deficits in adaptive and cognitive functioning, productivity may pose challenges for individuals with intellectual disability in the workplace. Method: Using a changing-criterion embedded in a multiple baseline across participants design, we examined the effects of differential reinforcement of high rates of behaviour (DRH) on…

Background: Factors influencing the implementation of communication partner training (CPT) with familiar partners of people with aphasia (PWA) have previously been documented using disparate approaches. To date there has been no synthesis of these factors using a common theoretical framework. Investigating CPT implementation factors using a common…

Recess is an important and unique component of the school day, and yet there is a relative paucity of research on its impact on young children. Moreover, recesses are often perceived negatively by educators because they can detract from academic instructional time and, depending on the kind of play and interactions between students, may also be…

It is commonly assumed that memories contribute to value-based decisions. Nevertheless, most theories of value-based decision-making do not account for memory influences on choice. Recently, new interest has emerged in the interactions between these two fundamental processes, mainly using reinforcement-based paradigms. Here, we aimed to study the…

Between 30 and 50% of individuals with Autism Spectrum Disorder (ASD) do not develop vocal language deemed functionally acceptable to meet their daily communication needs. As a result, individuals with ASD may require intervention alternatives to vocal speech, such as augmentative and alternative communication (AAC). However, very little is known…

Background: People with intellectual disabilities are more at risk of obesity than the general population. Emerging literature indicates that multicomponent interventions are most effective, however, individual results are variable and little research exists as to why this is the case. Methods: Focus groups were conducted to explore lived…

In this dissertation, the author presents two projects regarding teaching strategies that apply to an intelligent tutoring system (ITS). The author applied multiple-solution teaching methods to the ITSs. The first project is an ITS that aims to help college students learn how to use Computer-Aided-Design (CAD) software, FreeCAD ITS. The second…
