Baby finger lengths may reveal clues about early brain development
NCT ID NCT07525726
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether the ratio of a baby's index finger to ring finger (2D:4D) is linked to their motor skills and sensory processing. Researchers will measure finger lengths in 80 healthy infants aged 12-18 months and compare them to standardized tests of movement and senses. The goal is to better understand how prenatal hormones might shape early development.
