Frequent Blinking in Toddlers May Signal Stronger Cognitive Flexibility
A new study suggests that frequent spontaneous eye-blinking in children aged 3 to 6 is a reliable indicator of high cognitive flexibility and healthy brain development. Researchers found that children who blink more often perform better on tasks requiring rule-switching, a key skill for impulse control and academic success. This simple, non-invasive marker could help parents and educators monitor executive function without expensive brain scans.
