Cunningham and Stanovich reported a longitudinal investigation over 10 years that examined the unique influence of exposure to print in explaining individual differences on various measures of reading achievement and declarative (general) knowledge. The present study replicated their investigation with a larger number of participants and additional measures of literacy and language skills. Fifty-four 1st graders were administered reading, spelling, vocabulary, IQ, and listening comprehension measures and then followed to the end of 10th grade. At the end of 10th grade, they were administered an IQ test and measures of reading comprehension, language ability, general knowledge, and exposure to print. Results showed that 1st grade reading skills were a strong predictor of 10th grade outcomes. Second and third-grade reading skills were predictive of individual differences in print exposure even after 10th grade reading comprehension and language ability had been partialed. Individual differences in print exposure also predicted differences in the growth of reading ability, word decoding, spelling, vocabulary, and listening comprehension throughout the elementary grades. Findings confirm the powerful, long-term benefits of providing children with a fast start in reading and support the reciprocal nature of strong reading skills and engagement in reading and reading-related activities.
