I am the director of the Brain Dynamics & Cognitive Neuroscience Lab here at CWU. My research interests mainly deal with brain dynamics and the cognitive electrophysiology of the brain, specifically utilizing brain event-related potentials (ERPs) to study human cognition. My research has shown that there are slight differences in processing dichotic speech stimuli in young adults and I have extended this work to investigate effects of age-related hemispheric differences in the neural processing of dichotic information and linguistic processing.
Out of that body of research emerged another line of research interests dealing with the role of selective attention, hemispheric asymmetry, and its role in processing cognitive information. Our findings support the notion that ERP topographic asymmetries may be dependent on specific cognitive task demands (e.g., diotic vs. dichotic modes of presentation). In addition, data suggested that later occurring ERP components may better reflect interaural advantages for complex tones than earlier components, and may, therefore, be a more sensitive indicator of hemispheric specialization.
One of my new areas of interest is critical thinking, working memory and brain processing. We want to investigate how teaching techniques that foster critical thinking may alter brain electrophysiology and working memory. This project is in conjunction with the Department of Biology and Science Education.
In addition, my lab is also working on projects centered on the psychology of various aspects of online gaming and is in the process of creating a music cognition research group.
My lab team consists of both undergraduate and graduate students that are engaged at all levels of research. Students in my lab have been authors of conference presentations and scientific manuscripts.
