Delwin Lindsey is a professor of psychology at the Mansfield campus of Ohio State 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 & perception and introductory neuroscience, as well as elective courses in history of psychology and evolutionary psychology.

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 aspect of color vision, including the neural channels involved in processing chromatic information, the molecular genetics of color vision, and the early development of color vision in infants. His research has been reported in a number of media outlets in the U.S. and around the world.

Dr. Lindsey's most recent research interests lie at the intersection of color perception and cognition: the factors that can explain individual differences in color categorization, and the degree to which color appearance is influenced by how individuals think about color.  His research combines empirical and computational approaches to the study of color naming, visual search and color difference scaling.

Dr. Lindsey is a member of the Vision Sciences Society and the Optical Society of America.  He currently serves on the editorial board of the Journal of the Optical Society of America A.
