An exploratory study of the development of early syllable structure in reading-impaired children

Babbling between the ages of 8 and 19 months was examined in 19 children, 13 of whom were at high risk for reading disorder (RD) and 6 normally reading children at low familial risk for RD. Development of syllable complexity was examined at five periods across this 11-month window. Results indicated that children who later evidenced RD produced a lower proportion of canonical utterances and less complex syllable structures than children without RD. As syllable complexity is an early indicator of phonological sophistication, differences at this level may offer a window into how the phonological system of children with RD is structured. Future directions for this line of research are discussed.
