This study examined the emergence of fear expressions, based on survey reports from a quasi-representative sample of 957 Hungarian mothers. Infant girls showed fear expressions significantly earlier (3.48 weeks) than boys (4.28 weeks). Results indicate a possible gender-related development of facial expressions of fear in human infants.
