This study investigated the hypothesis that the contributions of oral language comprehension (C) and word recognition (D) to reading comprehension (R) in the simple view of reading (SVR) are not independent because a component of C (vocabulary knowledge) directly contributes to the variance in D. Three analysis procedures (hierarchical regression analysis, exploratory factor analysis, and structural equation modeling) were used to analyze data obtained from a sample (N = 122) of 7-year-old students who were administered tests of vocabulary knowledge, nonword reading, word recognition (two standardized tests), and parallel forms of listening and reading comprehension. Results from the regression analysis indicated that vocabulary made a contribution to R beyond that made by word recognition and listening comprehension; results from the exploratory factor analysis showed that two factors (Decoding …
