ABSTRACT

One of the most thoroughly studied forms of peripheral impairment, currently enjoying a considerable degree of interest (see, for example, the special edition of Cognitive Neuropsychology, 7 (5/6)), is neglect dyslexia. The hallmark of neglect dyslexia is the failure to report information appearing on the left. Neglect dyslexia patients may ignore the left side of an open book, the beginning words of a line of text, or the beginning letters of a single word.1 Neglect dyslexia is traditionally interpreted as a disturbance of selective attention (for detailed discussion, see Caramazza & Hillis, in press; Riddoch, Humphreys, Cleton, & Fery, in press). In neglect dyslexia, attention is unevenly distributed across the visual field, with maximal attention deployed to the right hemispace and considerably less to the left (Kinsbourne & Warrington, 1962). The consequence of such a deficit is that perceptual information on the left is not adequately processed and is thus often ignored.
