Temporal resolution in infancy and subsequent language development

The MacArthur Communicative Development Inventory, a parent-report measure of vocabulary and syntax, was administered to 103 children (M = 23 months) who had participated in a study of temporal resolution when they were 6 months (n = 55) or 12 months (n = 48) of age. Children who performed above the median on the temporal resolution task in infancy were subsequently reported to have larger productive vocabularies, greater numbers of irregular word forms, and longer and more complex sentences than those who had performed below the median. Whether these findings reflect specific links between temporal resolution and language or whether they reflect general developmental factors remains to be determined.
