Abstract
This longitudinal investigation charted the course of cognitive and language development from the prelinguistic period to multiword productions in 19 typically developing (TD) toddlers and 4 toddlers who were subsequently identified as having late onset of expressive language. Assessments were conducted at 3-month intervals over a 21-month period, with 12 months of prospective assessment data comparing the TD and late talker (LT) subjects (mean CA: 13 to 25 months) and 9 months of follow-up data (mean CA: 25–34 months) on the 4 subjects who were identified as late talkers at age 2. Three different developmental profiles were identified, and predictors of expressive language outcomes for the LT subjects were evaluated.
