Eye-catching odors: olfaction elicits sustained gazing to faces and eyes in 4-month-old infants.

This study investigated whether an odor can affect infants' attention to visually presented objects and whether it can selectively direct visual gaze at visual targets as a function of their meaning. Four-month-old infants (n = 48) were exposed to their mother's body odors while their visu...
