TY - JOUR T1 - Spelling dyslexia: a deficit of the visual word-form. JF - Journal of Neurology, Neurosurgery & Psychiatry JO - J Neurol Neurosurg Psychiatry SP - 211 LP - 216 DO - 10.1136/jnnp.57.2.211 VL - 57 IS - 2 AU - E K Warrington AU - D Langdon Y1 - 1994/02/01 UR - http://jnnp.bmj.com/content/57/2/211.abstract N2 - A patient with spelling dyslexia read both words and text accurately but slowly and laboriously letter by letter. Her performance on a test of lexical decision was slow. She had great difficulty in detecting a 'rogue' letter attached to the beginning or end of a word--for example, ksong--or in parsing two unspaced words, such as applepeach. By contrast she was immune to the effects of interpolating extraneous coloured letters in a word, a manipulation that affects normal readers. Therefore it is argued that this patient had damage to an early stage in the reading process, to the visual word form itself. ER -
