Early Childhood Cues: How Baby Behaviors Shape Adult Intelligence, New Study Shows
New research indicates that how a baby babbles, plays, and interacts in the first year can modestly forecast cognitive abilities into adulthood. A landmark twin study published in the Proceedings of the National Academy of Sciences followed 1,098 twins from infancy to age 30. It found that early-life behaviors and environments can account for about 10% to 13% of later cognitive variation, despite the many experiences that unfold over the decades.
