This study aimed to investigate the following questions: Does the use of thinking maps and semantic mapping during explicit vocabulary instruction affect content specific science vocabulary knowledge and comprehension in fourth grade students? and What are student perceptions of using thinking maps and semantic maps to learn new vocabulary? To…

Within the field of school psychology, the currently accepted structure of intelligence is the Cattell-Horn-Carroll Model (CHC). The CHC model contains three strata of abilities: a general ability (g), multiple broad cognitive abilities, and several narrow abilities (Schneider & McGrew, 2018), although the theoretical salience of the g factor…

This dissertation explores how items encountered in the comprehension of language are stored in memory and subsequently accessed. Processing and comprehending language frequently requires the retrieval of items in memory so that a current linguistic element can be assigned an interpretation. For example, in a sentence such as "Miles loved his…

Spatial thinking is important in predicting students' success in STEM fields. However, there is limited knowledge about "how" students learn spatial skills during classroom instruction by using strategies that support their cognition. This dissertation addresses this gap as I explored "spatial sensemaking practices" that…

Losing a close friend or family member is a common, but profoundly stressful life experience. For young adults in particular, bereavement is associated with depression, sleep difficulties, and other psychological sequelae of stress. An experience of loss commonly prompts some level of cognitive processing as an attempt to make meaning, but little…

Notions of accessibility bring to question the perceived deficits in narrative comprehension for autistic people. This deficit has been positioned as having a cognitive processing disposition towards local coherence, rather than global coherence. Rather than a unitary deficit in the individual, reduced performance on inferential narrative…

Two people in the same situation may ascribe very different meanings to their experiences. They will form different awareness, reacting differently to shared information. Various factors can give rise to this behavior. These factors include, but are not limited to, prior knowledge, training, biases, cultural factors, social factors, team vs.…

Purpose: The goal of the current research study was to advance our knowledge of cognitive-communicative disorders following traumatic brain injury (TBI) by identifying the cognitive and communicative processes underlying narrative discourse ability. The study (1) examined the role of working memory (WM) and inferencing in narrative discourse, (2)…

Research is not clear on how to address the difficulty students have conceptualizing geologic processes and phenomena. This study investigated how animations coupled with seductive details effect learners' situational interest and emotions. A quantitative quasi-experimental study employing an independent-measures factorial design was used. The…

Reports and surveys by the U.S. government and international organizations have repeatedly acknowledged the achievement problem in math in K-12 regardless of various efforts (e.g., by the U.S. Department of Education) to diminish it. To address the problem in math achievement in K-12, teachers, scholars, and the U.S. government have developed…

The purpose of this study was to introduce an instructional technique for teaching complex tasks in physics, test its effectiveness and efficiency, and understand cognitive processes taking place in learners' minds while they are exposed to this technique. The study was based primarily on cognitive load theory (CLT). CLT determines the amount of…

Early language research has revealed important insights into the building blocks of language, such as morphosyntactic features and rules and truth-conditions of sentences. Once we situate language in real-life use, however, a wide range of factors come into play. Language interacts not only with the surrounding linguistic context but also with the…

Information technology (IT) investment decision makers are required to process large volumes of complex data. An existing body of knowledge relevant to IT portfolio management (PfM), decision analysis, visual comprehension of large volumes of information, and IT investment decision making suggest Multi-Criteria Decision Making (MCDM) and…

Narrative has been formally studied for at least two millennia, dating back to the writings of Aristotle. While most theories began by describing the construction of plotlines in theatre, most contemporary research on the structure and comprehension of narratives has examined the discourse of spoken language. However, visual narratives in the form…

In many evolving systems, inputs can be derived from both human observations and physical sensors. Additionally, many computation and analysis tasks can be performed by either human beings or artificial intelligence (AI) applications. For example, weather prediction, emergency event response, assistive technology for various human sensory and…
