Abstract

Production of Approximants as Evidence for Phonological Deficits in Dyslexia. This paper presents the results of an experiment conducted under the hypothesis that dyslexics have disordered phonology. The hypothesis was tested by investigating dyslexics' production and manipulation of the approximants /l, r, w, j/ in consonant clusters (such as [bl] and [tr]). Two tests were administered: 1) a remove-consonant (Rosner) test (subjects remove the T sound from 'plan' and pronounce the result-'pan'- for example) and 2) a nonsense-word repetition test (nonsense words included, for example, 'teglape'). Twelve reading-disordered individuals with a mean age of 14 years, 5 months took part in the study. They were compared to a control group consisting of seven grade 2 normally-reading children. Results showed that poor readers had difficulty with the remove-consonant test and with the repetition of nonsense words. They made more errors than the control group on these tasks. Implications of these findings concerning the causes of dyslexia are discussed.
