Spontaneous eye-blink rate (sEBR) is a dopamine marker in children and was found to correlate with high executive functioning in preschool-aged children when performing the study.
Researchers recruited 113 children from Japan, aged 3-6, to participate in a classic cognitive flexibility test: a card-sorting game…
