Dr. J. Stephen Mansfield
Professor of Psychology, Cognitive Psychology
My recent research concerns the perceptual and cognitive processes involved in reading. For example: How does reading performance depend on print size? How is reading speed influenced by typeface? How can we improve the reading performance of individuals with low vision or children with dyslexia?
