In families with two working parents,fathers may have more impact on a child's language development than mothers,a new study suggests.
Researchers recruited 92 families from 11 child care centers before their children were a year old,interviewing each to establish income,level of education and child care arrangements.Over all,it was a group of well-educated middle-class families,with married parents both living in the home.
When the children were 2,researchers videotaped them at home in free-play sessions with both parents,recording all of their speech.The study will appear in the November issue of The Journal of Applied Developmental Psychology.
The scientists measured the total number of utterances of the parents,the number of different words they used,the complexity of their sentences and other aspects of their speech.On average,fathers spoke less than mothers did,but they did not differ in the length of utterances or proportion of questions asked.
Finally,the researchers analyzed the children’s speech at age 3,using a standardized language test.The only predictors of high scores on the test were the mother’s level of education,the quality of child care and the number of different words the father used.
The researchers are unsure why the father’s speech,and not the mother’s,had an effect.
“It’s well established that the mother’s language does have an impact,” said Nadya Pancsofar,the lead author of the study and a graduate research assistant at the Frank Porter Graham Child Development Institute at the University of North Carolina.It could be that the high-functioning mothers in the study had already had a strong influence on their children’s speech development,Ms.Pancsofar said,“or it may be that mothers are contributing in a way we didn’t measure in the study.”
