Delwin Lindsey is a professor of psychology at the Mansfield campus of 91°µÍø University. He received an A.B. in physics from Pomona College and a Ph.D. in biopsychology from the University of Chicago. In the classroom, Dr. Lindsey teaches core courses in introductory psychology, sensation and perception and behavioral neuroscience, as well as an elective course in history of psychology. In addition to his teaching at the undergraduate level in Mansfield, Dr. Lindsey also mentors graduate students in psychology and the College of Optometry on the 91°µÍø-Columbus campus.

Dr. Lindsey’s research focuses on human vision, with particular emphasis on color vision. He has authored or co-authored original scientific articles on many aspects of color vision, including the neural channels involved in processing chromatic information, the molecular genetics of color vision, the early development of color vision in infants, and the categorization and naming of colors in adults. His research has been reported in a number of media outlets in the U.S. and around the world.

Dr. Lindsey's is probably best known in the academic community for his research on individual and cross-cultural differences in color categorization. His research in this area combines several novel empirical and computational approaches to the study of the mental representations of color in humans. Dr. Lindsey is currently engaged in two related areas of research: 1) the neurophysiological basis of color appearance and 2) how humans communicate about the properties, such as color and texture, of materials that things are made of.  

Dr. Lindsey is a member of the Vision Sciences Society and the Optical Society of America. He is a past member of the editorial board of the Journal of the Optical Society of America A and has since served occasionally as guest editor on special issues of that journal.
