Abstract: The role of olfactory cues in maternal recognition of neonates was investigated. Mothers were able to identify the garments worn by their own infants (in comparison to garments worn by unfamiliar infants) through odor alone within the first 6 days postpartum. In a second experiment, mothers who had only limited pre-test exposure to their infants recognized the odor of their infant's garment during tests conducted at 20.5–41.7 hr after delivery. Olfaction may be an especially salient modality for recognition of infants.
