Adults with developmental disabilities and educational researchers have identified many holes in the practices currently used to educate non-speaking youth with developmental disabilities, especially those with extensive support needs (Kapp, 2020; Taub, et al., 2017). While technology cannot provide a magical, sweeping fix to barriers to…

The purpose of this phenomenological study is to investigate the impact of instructional design elements on cognitive load for adult neurodiverse learners in online learning environments. For the utility of this study, cognitive load will be generally defined as the working memory and mental resources needed to perform a task. This study is…

Purpose: This quality improvement (QI) project evaluated the effectiveness of an educational intervention to enhance adult ADHD patients' understanding and acceptance of Mindfulness-Based Cognitive Therapy (MBCT) as an augmentative treatment. The goal was to encourage participants to pursue an MBCT referral from their provider. This initiative was…

This dissertation investigates the interplay between the implicit knowledge that learners have of a nonnative language and their processing of that language, examining two types of relative clauses (RCs) in English: gapped RCs (e.g., "the man that they hired") and resumptive RCs (e.g., *"the man that they hired him").…

This dissertation investigates the interaction of developing extralinguistic cognitive systems with early language learning and processing through the case study of verb argument structure. The interaction of these systems with the linguistic system underpins fundamental theories of language learning and use: language does not exist in isolation.…

Many Hispanic adult immigrants to the United States acquire sufficient English skills to enable them to function in daily life but are left feeling that their skills are inadequate for college work. The problem addressed by the study is that the factors that are predictive of successful acquisition of college-level English skills had not been…

Traumatic brain injury (TBI) may result in a wide array of cognitive deficits, including executive functions. A proposal by Ferretti and colleagues (2011 & 2013) has suggested that executive dysfunction caused by traumatic brain injury (TBI) impact navigation and discourse abilities in similar ways, suggesting that these skills may share…

The perception and encoding of voice cues in consonants have been well studied, whereas there has been relatively little research on aspiration. The current study examined the encoding and perception of aspiration and voicing in Hindi, American English, and Tamil listeners when relevant cues were and were not degraded by noise. This study is novel…

In this research, I used a mixed-methods approach employing both autobiographical reasoning and psychometric instruments through a survey design to explore how the four cognitive mechanisms of Work Identity Theory (WIT) were developed in 754 college-educated participants' lives. WIT is a vocational identity theory, which posits that, four…

Researchers have investigated the promise of unimodal and bimodal input in enhancing vocabulary learning from meaning-focused activities. Compared to unimodal input, the simultaneous presentation of written and aural input in bimodal input has been argued to direct L2 learners' attention to words and enhance the form-meaning links for new…

In natural language, evidence suggests that, while some rules are productive (regular), applying broadly to new words, others are restricted to a specific set of lexical items (irregular). Further, the literature suggests that children make a categorical distinction between regular and irregular rules, applying only regular rules productively…

This study investigated the effect of multiple text-graphic interventions to facilitate conceptual change on the topic of human induced climate change. Given the superiority of refutation texts over standard expository texts, the goal of the present study was to determine if this effect could be enhanced, thereby creating an even more powerful…

In Barkley's (1997a, 1997b) model of attention-deficit/hyperactivity disorder (ADHD), he proposes that working memory deficits resulting from ADHD may cause impairments in reading comprehension. ADHD has been associated with poorer processing speed and working memory as well as academic underachievement in some studies. However, more research is…

Researchers in the field of second language acquisition continue to establish links between cognition and emotion (Dewaele, 2013; MacIntyre, 2002; MacIntyre & Gardner, 1989, 1991b, 1994; Segalowitz & Trofimovich, 2011). The purpose of the present study is to investigate to what extent physiological and self-report measures predict…

Systems that can detect cognitive decline or harmful levels of stress could assist users in managing their stress and health. However, current assessments are often obtrusive or require specialized equipment, and not suited to continuous monitoring of cognitive status. This research leverages attributes of everyday keyboard interactions to…
