What is it about?
Previous studies have provided detailed information on early lexical development during the 2nd year of life. However, it has not been clear what kind of associations, if any, there exists between early receptive and expressive lexical development and later language ability. This study investigated specific associations between early receptive and expressive lexical development, when measured using a new screening instrument during the second year of life, and language skills at 5 years of age.

Why is it important?
We found significant associations between receptive/expressive lexical skills at 18 months / at 24 months of age and language skills at 5;0 years. Both receptive language and expressive lexical development measured at 2;0 years were relatively evenly associated with different types of language skills at 5;0 years. The best models including early lexical predictors explained 20–34% of language outcome three years later.
Perspectives
PhD student Suvi-Maria Vehkavuori did a great job as a first author of this study and it was a pleasure working with her. This study is part of the adaptation and norming study of the Finnish short form version of the MacArthur Communicative Development Inventories, and results provide further information on the usability of this new instrument. We hope that results can be used in clinical context when assessing very lexical development of children.
