Purpose: The aim of this study was to investigate the language outcomes of 7-year-old children with and without a history of late language emergence at 24 months.
Method: One hundred twenty-eight children with a history of late language emergence (LLE) at 24 months and 109 children with a history of normal language emergence (NLE) at 24 months participated in direct behavioral assessment of multiple dimensions of language at 7 years. The children were recruited from a prospective cohort study of 1,766 epidemiologically ascertained 24-month-old singleton children.
Results: The group mean for the LLE children was within the typical range on an omnibus measure of general language ability and measures of specific dimensions of language. However, a greater percentage of LLE children, relative to NLE children, performed below normative expectations on a measure of general language ability (20% versus 11%), speech (7% versus 2%), syntax (18% versus 8%), and morphosyntax (9%-23% versus 2%-14%), but not vocabulary or semantics.
Conclusion: The results provide support for growth models of language impairment that predict that late onset of language foretells a protracted growth difference for some LLE children relative to NLE children, particularly for syntax and morphosyntax.
KEY WORDS: late talking outcomes, specific language impairment, longitudinal study

Kerry,
I recently received this info from Cindy Earle, Program Manager for
Target Word^® - The Hanen Program^® for Parents of Children who are Late
Talkers:
"New research findings from the world's largest study on language
emergence have revealed that /one in four late talking toddlers continue
to have language problems at age 7/.^1
Mabel Rice, one of the study's primary investigators, stated that,
"While a late start doesn't necessarily predict ongoing language
problems, most school-aged children with impaired language were late
talkers."
This is the reference:
^1 Rice, M.L., Taylor, C.L., & Zubrick, S.R. (2008). Language Outcomes
of 7-Year-Old Children With or Without a History of Late Language
Emergence at 24 Months. /Journal of Speech, Language and Hearing
Research/, /51,/ 394-407.
Hope this is useful.
Sharon
