This is the OSF site for the project entitled "The (null) effect of socio-economic status on the language and gestures of infants learning ten languages"
Abstract: In industrialised societies, children from under-resourced communities, or whose parents have less education, are more likely to have slower language growth. However, most evidence for this effect of socio-economic status (SES) comes from older children. In this study, the effect of SES on language in 8-18 month old infants using two large, demographically diverse samples of children living in the UK and Poland was assessed, and compared to existing data from children in eight different countries (USA, Denmark, Latvia, Taiwan, Norway, Portugal, Mexico, Spain). There was no systematic evidence for slower vocabulary or gesture growth in children from lower SES families, suggesting that substantial SES-related differences in language development do not emerge until after the first year of life.
