Retrieval rate, accuracy and vocabulary elaboration (RAVE)in reading-impaired children: a pilot intervention programme

Although most severely reading-impaired children are characterized by two core deficits in phonological and naming speed processes, most current interventions emphasize only phonological skills. The present study assessed the efficacy of an eight-week pilot intervention programme designed to increase the speed and accuracy of naming or lexical retrieval skills. Because of the close relationship between word knowledge and the speed with which a word is retrieved, a second goal was to increase the depth and breadth of vocabulary knowledge. Subjects for the intervention included 17 severely impaired readers (mean age 13 years). Included for pre-intervention reader group comparisons were 31 average readers matched for reading age (mean age 10 years). Significant pre-intervention differences favouring controls were found on all naming speed measures and two measures of vocabulary depth. There were no differences in receptive vocabulary. Pre- and post-intervention comparisons for impaired readers indicated significant gains on word retrieval accuracy and vocabulary depth. There was significant generalization to an untrained naming speed task. Implications for diagnosis and treatment of reading-impaired children are discussed. Copyright © 1999 John Wiley & Sons, Ltd.
