Kind: research · Impact: medium

## In brief

- A study published in Nature Human Behaviour finds that genetic variants associated with children's thinking, learning and problem-solving change in their associations between early childhood and adolescence.
- The research tracked thousands of British children from age 4 to age 16.
- The source reports the findings only in summary, so details such as effect sizes are not available here.

## Why it matters

It suggests that genetic links to cognitive ability are not fixed across development, which matters for how researchers interpret genetic studies of intelligence measured at different ages.
