Pure 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 کاملWord-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 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 کاملStructural anatomy of pure and hemianopic alexia.
BACKGROUND The two most common types of acquired reading disorder resulting from damage to the territory of the dominant posterior cerebral artery are hemianopic and pure alexia. Patients with pronounced hemianopic alexia have a right homonymous hemianopia that encroaches into central or parafoveal vision; they read individual words well, but generate inefficient reading saccades when reading a...
