چکیده

We present a theoretical account of letter-by-letter reading (LBL) that reconciles discrepant findings associated with this form of acquired dyslexia. We claim that LBL reading is caused by a deficit that affects the normal activation of the orthographic representation of the stimulus. In spite of this lower-level deficit, the degraded orthographic information may be processed further, and lexical, semantic, and higher-order orthographic information may still influence the reading patterns ofthese patients.In supportof our position, w e present a review of 57 published cases of LBL reading in w hich w e demonstrate that a peripheral deficit was evident in almost all of the patients and that, simultaneously, strong effects oflexical/ semantic variables were observed on reading performance. We then go on to report findings from an empirical analysis of seven LBL readers in whom w e document the joint effects of lexical variables (word frequency and im ageability) and word length on naming latency. We argue that the reading perform ance of these patients reflects the residual functioning of the same interactive system that supported normal reading premorbidly.

Number reading in pure alexia—A review

It is commonly assumed that number reading can be intact in patients with pure alexia, and that this dissociation between letter/word recognition and number reading strongly constrains theories of visual word processing. A truly selective deficit in letter/word processing would strongly support the hypothesis that there is a specialized system or area dedicated to the processing of written word...
