Babies who gesture have bigger vocabularies: study
By Julie Steenhuysen
CHICAGO (Reuters) - Babies who use many gestures to communicate when they are 14 months-old have much larger vocabularies when they start school than those who don't, U.S. researchers said on Thursday.
They said babies with wealthier, better-educated parents tend to gesture more and this may help explain why some children from low-income families fare less well in school.
"When children enter school, there is a large socioeconomic gap in their vocabularies," said the University of Chicago's Meredith Rowe, whose study appears in the journal Science.
Gestures could help explain the difference, Rowe told the American Association for the Advancement of Science annual meeting in Chicago.
Vocabulary is a key predictor of school success. Earlier research showed that well-off, educated parents tend to talk to their children more than their poorer, less-educated peers.
"What we are doing here is going one step earlier and asking, does this socioeconomic status relate to gesture, and can that explain some of the gap we see at school entry," Rowe said.
The researchers filmed 50 Chicago-area children and parents from diverse economic backgrounds and counted the number of gestures, such as pointing at a picture.
The team found that 14-month-olds from high-income, well-educated families used gesture to convey an average of 24 different meanings during each 90-minute session, compared with 13 meanings conveyed by children from lower-income families. Continued...
