Word recognition plays an essential role in learning to read, skilled
reading, and dyslexia. The goal of the research I describe is to devel
op a theory of word recognition that is realized as a connectionist si
mulation model. Experience with a first-generation model suggests that
the approach can reveal general principles underlying word recognitio
n and its impairments. Although computational modeling introduces new
problems of method and interpretation, it contributes in an essential
way to understanding reading and other aspects of cognition.
