Word-Superiority in Pure Alexia
Pure alexia is an acquired reading disorder where patients lose the ability to read fast and fluently, but are commonly able to identify words letter-by-letter. This is evidenced by a pronounced word-length effect in reading, where reaction times (RTs) increase linearly with word length. The severity of the reading deficit in pure alexia has been reported to be systematically related to perform...
متن کاملPure Alexia
Pure alexia is a reading disorder that occurs in literate individuals secondary to a lesion in the left occipito-temporal region. The hallmark of this deficit is the word-length effect: the naming latencies of patients increase dramatically with increasing numbers of letters in the word. For example, every additional letter can take a further 3 s for a patient who is reading a word aloud [compa...
متن کاملPerceptual Cues in Pure Alexia
This study provides evidence that pure alexia, or letter-by-letter reading, may be attributed to a general perceptual de ® cit that extends beyond an orthographic disorder. The perceptual problem may be unmasked when appropriate perceptual cues are not available to aid in the derivation of an integrated structural description. Four pure alexic patients and eight nonbrain-damaged controls partic...
متن کاملPhonological activation in pure alexia.
Pure alexia is a reading impairment in which patients appear to read letter-by-letter. This disorder is typically accounted for in terms of a peripheral deficit that occurs early on in the reading system, prior to the activation of orthographic word representations. The peripheral interpretation of pure alexia has recently been challenged by the phonological deficit hypothesis, which claims tha...
متن کاملNumber 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...
