The Impact of Language and Social Status on Brain Development

A study led by Laia Fibla at Concordia University has examined how language environment and socioeconomic status (SES) impact the development of the brain's white matter tracts during early childhood. The research found that children from families with higher SES scores had more exposure to adult words, and this was positively correlated with higher concentrations of myelin in language-related white matter tracts. The study highlights the importance of early language input in shaping the development of language circuitry in the brain.
