science πΆ Newborn girls look longer at faces, study finds
A new study revealed that newborn girls spend more time looking at human faces compared to infant boys. Researchers at the University of Cambridge observed this trend within hours of birth, before social expectations influenced attention. The 130 infants were shown videos of faces versus metallic balls, published in Biology of Sex Differences. Prenatal factors like hormones and genetics are thought to contribute to these early sex-based differences in focus. This research adds to the nature vs nurture debate by suggesting prenatal influences play a role.
