Children With Differing Developmental Trajectories of Prelinguistic Communication Skills: Language and Working Memory at Age 5

Sira Määttä - Nama Orang; Marja-Leena Laakso - Nama Orang;

In this article, the authors examine the developmental continuity from prelinguistic communication to kindergarten age in language and working memory capacity.Method: Following work outlining 6 groups of children with different trajectories of early communication development (ECD; Määttä, Laakso, Tolvanen, Ahonen, & Aro, 2012), the authors examined their later development by psychometric assessment. Ninety-one children first assessed at ages 12–21 months completed a battery of language and working memory tests at age 5;3 (years;months). Results: Two of the ECD groups previously identified as being at risk for language difficulties continued to show weaker performance at follow-up. Seventy-nine percent of
the children with compromised language skills at follow-up were identified on the basis of the ECD groups, but the number of false positives was high. The 2 at-risk groups also differed significantly from the typically developing groups in the measures tapping working memory capacity. Conclusions: In line with the dimensional view of language impairment, the accumulation of early delays predicted the
amount of later difficulties; however, at the individual level, the prediction had rather low specificity. The results imply a strong link between language and working memory and call for further studies examining the early developmental interaction between language and memory.

Key Words: language impairment, working memory,
