Reading is a fundamental cognitive skill that is often disrupted as a consequence of brain damage. The study of neurological patients with acquired reading disorders has proven pivotal in development of theoretical accounts of normal reading. This work initially involved a focus on cases of dissociation between reading and other cognitive functions using single case methodology. This evidence was influential in the formation of dual-route models of reading aloud which employ localist representations. More recent work has used simultaneous consideration of multiple cases to reveal associations between reading and other cognitive functions. This evidence has been captured by connectionist triangle models of reading aloud, which rely upon learned distributed representations. Neuroimaging of patients with acquired dyslexia has provided insights into the mechanisms of dysfunction and the neural basis of normal reading. Consideration of neuropsychological patient data has highlighted the role of more basic perceptual and cognitive processes in skilled reading.
