Abstract
Goswami (1986, 1988) has demonstrated that children can use orthographic analogies (particularly at the onset-rime level) between the spelling patterns in words to help to decode new words (e.g. using 'beak' to read 'peak'). This strategy has been shown in children as young as six years old. Since it is known that children with developmental dyslexia find it particularly difficult to read words that they have not been specifically taught (Lovett, Warren-Chaplin, Ransby & Borden, 1990), the present study investigated whether dyslexic children might be unable to use analogies. Employing a design similar to that used by Goswami (1988), it was hypothesized that dyslexics would find it difficult to transfer spontaneously knowledge of a 'clue' word to decode new words that could be read by analogy with the clue word. The results of Expt 1 indicated that the dyslexic readers read significantly fewer of the analogous words than a reading age-matched comparison group of younger children. Furthermore, none of the nine dyslexic children read as many of the analogous words as the lowest scoring control child. In a second experiment, a design similar to that of Muter, Snowling & Taylor (1994) was used with a new and larger sample of dyslexic children. In this experiment, all the children were brought to criterion in reading the clue words before the analogous words were presented. Once again, the dyslexic children read significantly fewer words that were analogous with the clue words than did a reading age-matched comparison group. The number of analogous words that the dyslexic children read was significantly correlated with their performance on a test that is sensitive to the ability to detect rhyme. It is argued that a failure to make analogies may be one of the main causes of the reading impairment experienced by children with developmental dyslexia.
