Additional Information


Dr. Sotozaki studied Cognitive Psychology at Carleton University, Ottawa, Canada. She received her BA, MA and Ph.D. at Carleton University. Her dissertation was entitle, “The Involvement of Interhemispheric Interaction in Developmental Dyslexia”.


Dr. Sotozaki teaches at all levels (100, 200, 400, including a graduate seminar class). She enjoys teaching Cognitive Processes (PSY456) and Child Development (PSY221-Face-To-Face and Online) as well as introductory Psychology (PSY100).


Dr. Sotozaki’s research has focused on language, reading and emotions from the perspective of laterality, i.e., how differently the left and right brains process and integrate external information. Particularly, she is interested in dyslexia and alexithymia. General research questions would include: Why is reading easy for some people and isn’t for others? Are there good programs for children with reading difficulty? Is phonological processing essential in non-alphabetical languages such as Japanese? Dr. Sotozaki uses both behavioral measurements (reaction time and accuracy) and physiological measurements (event-related potentials (ERPs) for her research.
