The present research follows up on two previous findings: that children with minimal dual language exposure have smaller receptive vocabularies at 16 months and that maternal education is a predictor of vocabulary when the dominant language is English but not when it is Spanish. The present study extends this research to 22-month-olds to assess the developmental effects of minimal exposure and maternal education on direct and parent-report measures of vocabulary size. The effects of minimal exposure on vocabulary size are no longer present at 22 months of age, whereas maternal education effects remain but only for English speakers.
