Kids hang on to dad's every word

New Scientist reports:

Fathers: watch what you say. It seems dads may have more of an influence on their children's language development than they might think.

Lynne Vernon-Feagans at the University of North Carolina, Chapel Hill, and her colleagues sat in on playtime with 92 families with dual incomes, observing how much each parent spoke to their child, the words and sentence structures they used, and the types of questions they asked.

Children whose father's vocabulary was more varied when they were 2 years old had more advanced language skills at age 3. Surprisingly, the dads spoke less and asked fewer questions than the mothers, suggesting it was not how much they spoke but what they said and how they said it that resonated with their children.

The mother's vocabulary did not seem to have a significant impact on language development.

People tend to assument that because moms typically spend more time with kids, that the dads' influence is extraneous. Many studies say otherwise.
