A possible contribution of word-retrieval difficulties to reading and spelling impairments

Good and poor readers at the junior high school level and good and poor spellers at the university level were compared on their ability to produce words in response to a semantic cue (a category name), a visual cue (three letters), and an auditory cue (a syllable rime). Kindergarten children were tested on a word-identification task and their retrieval of words in response to the semantic and auditory cues. At all ages, poor readers or spellers produced fewer words on all word-retrieval tasks than did good readers or spellers. Performance on the auditory and visual word-retrieval tasks correlated very highly with pseudoword reading and spelling ability in the two older groups; in the kindergarten children, auditory retrieval correlated with word identification. The results suggest that poor readers have not organized words in long-term memory according to rhyming families but that good readers have. We speculate that failure to retrieve rhyming words during acquisition of reading and spelling skills underlies the failure of poor readers and spellers to abstract the higher-order relationships between orthography and phonology.
