patient with left visual neglect following a right hemisphere infarction is described. When presented with isolated words and nonwords, she made left neglect errors in reading aloud, but not in direct copying. This finding suggests a distinction between two ways of processing orthographic stimuli: depending on the task, the unit of processing can be the letter string or the single letter. In reading, the letter string is treated as a whole while in copying it is processed element-by-element. Left neglect differentially affects the processing of single words: in reading errors involve the left, initial letters, while in copying they involve the single letters, or the left part of the letters, independently of their position within the stimulus.

Abstract
patient with left visual neglect following a right hemisphere infarction is described. When presented with isolated words and nonwords, she made left neglect errors in reading aloud, but not in direct copying. This finding suggests a distinction between two ways of processing orthographic stimuli: depending on the task, the unit of processing can be the letter string or the single letter. In reading, the letter string is treated as a whole while in copying it is processed element-by-element. Left neglect differentially affects the processing of single words: in reading errors involve the left, initial letters, while in copying they involve the single letters, or the left part of the letters, independently of their position within the stimulus.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione
