I am a cognitive psychologist, and the work that I have done during the past 20 years has been at the interface between perception and memory. In addition, I come to that work with a strong psycholinguistics perspective. My research has been on word recognition and lexical access (reading), and it has focused on both the early visual information processing and the manner in which the product of that processing is use to retrieve the appropriate lexical entry from memory. Specifically, my work examines the nature of the perceptual representation used as a basis for accessing the lexicon, the manner in which lexical entries represent lexical information, and the process whereby the perceptual representation is used to select a representation from within the lexicon.
