Abstract View Full Summary
We seek to develop predictive models of low language (LL) outcomes in preschool and school age by analyzing parental report measures of early language skill using machine learning and network science approaches. We initially harmonize two longitudinal datasets of young children including demographic and standardized measures of early language skills (the MacArthur-Bates Communicative Developmental Inventories; MBCDI) as well as a later measure of LL (verified via CELF-P2 in one dataset, and parental report of school-age language disorder in the other). We additionally use item-level MBCDI data to calculate several graph-theoretic measures of lexico-semantic structure in toddlers’ early expressive vocabularies. We use machine-learning techniques to construct predictive models to identify toddlers who will have later preschool and school-aged language delays in these datasets. Our analyses illustrate that this approach yields robust and reliable predictions of later LL outcome with classification accuracies in single datasets exceeding 90%. Demographic variables and grammatical and lexico-semantic measures ranked highly in predictive classification, suggesting promising avenues for early screening initiatives and delineating the roots of language disorders.
