Models of speech perception and phonological processing in reading

Abstract

Multiple measures of speech perception, phonological awareness, naming speed, verbal short-term memory, and word reading were concurrently administered to 136 third- and fourth-grade children. Structural equation modeling was used to contrast 5 models of the relations of speech perception and phonological processing skills to reading with IQ controlled. The best-fitting model, the Indirect Model, was one in which the effect of speech perception on reading was mediated by its relations with phonological processing abilities. Naming speed was particularly highly associated with speech perception, possible evidence for the Motor Theory. Phonological awareness was also substantially correlated with speech perception.
