Having an older brother would be associated with slower language development

Several studies had already shown that children with an older sibling have poorer language performance than those without an older sibling. But a research team from the CNRS, Robert-Debré AP-HP hospital, EHESS, ENS and Inserm has just specified this result: it would only concern children with an older brother. This work was published on August 14 in the journal Psychological Science.
