The Growth of Early Phonological and Lexical Development: A Longitudinal Investigation
"In addition, differences in phonological and lexical measures at 18 months were examined as a function of gender and maternal education. Significant differences were observed for all three of the outcome variables: number of different consonants, number of different words, and the percentage of vocalizations classified as lexical. Girls outperformed boys as did children of mothers who had completed ""16 plus years"" of education when compared to children of mothers who had completed ""up to 15 years"" of education."
