　　Babies who use many gestures(手勢)to communicate when they are 14 months old have much larger vocabularies when they start school than those who don't, US researchers said．

　　They said babies with wealthier, better-educated parents will probably sign more．This may help explain why some children from low-income families perform less well in school．

　　“When children enter school, there is a large difference 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 yearly meeting in Chicago．

　　Vocabulary is an important predictor of school success．Earlier research showed that rich, educated parents tend to talk to their children more than poorer, less-educated ones．

　　“What we are doing here is asking：Does this social-economic situation relate to gestures？Can that explain some of the difference we see at school entry(進(jìn)入)?” Rowe said．

　　The researchers filmed 50 Chicago-area children and parents from different 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 gestures to express about 24 different meanings during 90 minutes．Children from lower-income families expressed 13 meanings．

　　When the same children entered school at age four and a half, those from higher-income families had better vocabulary scores on standardized tests．

　　“At 14 months, an age when there aren't even social-economic differences in their talk yet, we see there are differences in their gestures,” Rowe said．

　　The videos found that parents from wealthier families gestured more with their children than the other parents．

　　Rowe said the findings suggest that gestures can at least partly explain vocabulary differences between the groups, and may prove useful as the basis for interventions(干預(yù))．

　　“Can we control how much parents and children gesture, and if so, will it increase their vocabulary?” Rowe asked．
