The interaction between phonological processing, syntactic awareness, and naming speed in the reading and spelling performance of first-grade children.

The performance of 267 first-grade children was examined on tasks assessing phonological processing, syntactic awareness, and naming speed. The children were also given several measures of word and pseudoword reading, reading comprehension, and pseudoword and dictation spelling. A series of hierarchical analyses indicated that three variables (phonological awareness, syntactic awareness, and naming speed) were still predictors of reading and spelling performance after variance in the others had been controlled for. The results, which confirm that syntactic awareness can account for variance in written language after phonological ability had been controlled for, support the hypothesis concerning the relationships between naming-speed processes and written language, and challenge the unitary phonological theory of reading difficulty.
