Many studies going back to the 1950s have found that parental levels of education or income affect their children’s brains. Now a new study at Boston Children’s Hospital, published in the journal Developmental Science, has found that how a mother perceives herself in comparison to other mothers may also impact her child’s brain development. Specifically, the mother’s perceived level of social status consistently predicted levels of two things in the children’s brains: the stress hormone cortisol and activation in some of the brain’s memory areas. Margaret Sheridan PhD of the Labs of Cognitive Neuroscience and the study’s first author said: "Our results indicate that a mother's perception of her social status 'lives' biologically in her children."
