Teachers working in a special education self-contained classroom were required to implement evidence-based practices and interventions, rarely researched in a school setting, with fidelity to meet the needs of students with intellectual disabilities. Evidence-based practices and interventions for students with intellectual disabilities were…

Individuals diagnosed with autism spectrum disorder (ASD) who engage in stereotypy may also emit a prior, temporally contiguous, high-risk response to access stereotypic behaviors. For example, the participant in this study who was diagnosed with ASD engaged in a chained response that included elopement, often in unsafe locations, to access light…

Producing content-related gestures has been found to impact students' learning, whether such gestures are spontaneously generated by the learner in the course of problem-solving, or participants are instructed to pose based on experimenter instructions during problem-solving and word learning. Few studies, however, have investigated the effect of…

The ability to reason and problem-solve in novel situations, as measured by the Raven's Advanced Progressive Matrices (RAPM), is highly predictive of both cognitive task performance and real-world outcomes. Here we provide evidence that RAPM performance depends on the ability to reallocate attention in response to self-generated feedback about…

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…

The context in which reward-paired cues are encountered can resolve ambiguity and set the occasion for appropriate reward-seeking. The psychological processes by which contexts regulate reward-seeking remain unclear as contexts are diffuse and difficult to isolate from other stimuli. To overcome this, we modeled a context as a phasic and discrete…

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…

Non-compliance is a challenge for practitioners serving children with and without disabilities. Many interventions have been developed to increase compliance. High-probability request sequences (HPRS), an antecedent-based intervention that is based on behavioral momentum theory, is one way to increase compliant behavior. HPRS includes the…

This dissertation investigates an overarching research question: how can recognition-type incentives, such as gamification and peer gifting, motivate users' knowledge seeking and contributions in e-learning and online Q&A (question and answer) communities? To address this question, I conducted three studies. In Chapter 2, I examine how social…

Individuals with intellectual and developmental disabilities have increased risk for developing challenging behavior. One particularly dangerous topography of challenging behavior is rapid eating. Rapid eating can lead to increased risk for choking and obesity as well as negatively impact social interactions during mealtimes (Anglesea et al.,…

Successful social inclusion of children with autism in mainstream preschool settings requires ongoing social interactions with neurotypical (NT) peers. To meet the social needs of children with autism in these settings, NT peer training is needed. We evaluated the effects of video modeling, self-management, and reinforcement on social responses of…

Fetal alcohol spectrum disorder (FASD) is characterized by impulsivity and deficits in executive functioning. Given this, individuals with FASD might particularly benefit from interventions that teach them to manage their own behavior in a more adaptive manner. Using a reversal (ABAB) design, the current study investigated the effects of a…

Student behavioral problems are a concern among educators in Cyprus. Policy and practice measures implemented in Cyprus have primarily focused on addressing problem behaviors at the individual level. Recently, behavior support implementations have occurred at a schoolwide level. This mixed methods study presents the results of two model…

Functional communication training (FCT) is an evidence-based intervention that while often effective, can result in rote responding, reduced generalizability of target behavior, and resurgence of challenging behavior (CB) during treatment lapses. Lag schedules of reinforcement have been successfully used to address these concerns. We applied an…

Behavioral flexibility is important in a changing environment. Previous research suggests that systems consolidation, a long-term poststorage process that alters memory traces, may reduce behavioral flexibility. However, exactly how systems consolidation affects flexibility is unknown. Here, we tested how systems consolidation affects: (1)…
