Language and Reading Outcomes to Age 9 in Late-Talking Toddlers

Language and reading outcomes at 6 to 9 years of age were examined in a sample of 34 children who were late talkers as toddlers. The late talkers, who all had normal nonverbal ability and age-adequate receptive language at intake, were compared to a group of 25 typically developing children matched at intake (24 to 31 months) on age, socioeconomic status, and nonverbal ability. Late talkers performed in the average range on most language tasks by age 5. However, they had significantly poorer scores on most language measures through age 9. The groups did not differ in reading skills at age 6 or 7, but the late talkers were slightly less skilled in reading at ages 8 and 9. Findings suggest that slow early language development reflects a predisposition for slower acquisition and lower asymptotic performance in a wide range of language-related skills into middle childhood.
