Co-speech gesture in monolinguals has been linked to several cognitive processes: prompting memory stores, conveying spatial concepts, searching for lexical equivalents, and supporting rhythm and cohesion. The production of co-speech gesture also occurs in spoken language bilinguals. Studies have demonstrated that bilinguals fluent in American…

Embodied cognition posits that physical interactions with the environment play a crucial role in learning, including complex, abstract concepts in STEM disciplines. This is relevant for deaf and hard-of-hearing (DHH) learners who often utilize sign language, which is a naturally embodied, visuospatial mode of communication. My dissertation…

Deaf and hard of hearing (DHH) students' performance on fraction story problems is a cause for concern given that knowledge of fractions in the elementary grades is essential for learning Algebra in secondary school and advanced mathematics in college. Using grounded theory, the current study investigated DHH college students' cognitive strategies…

This dissertation centers on the application of the mental space theory to expand our understanding of the role lexical discourse markers (LDMs) play in discourse. LDMs have been recognized by many researchers for their discourse connective function(s) (Levinson, 1983; Schiffrin, 1987; Blakemore, 1989, 2000, 2001, 2002; Fraser, 1996, 1999, 2006).…

Previous research has provided evidence that mental imagery and embodied action can facilitate lexical learning in a novel language. However, it is unclear "how" these factors interact--as well as "why" they play a role--in lexical learning. Through a set of four experiments, this research demonstrated that neither mental…
