Face detection in complex visual displays: An eye-tracking study with 3- and 6-month-old infants and adults

The ability to detect and prefer a face when embedded in complex visual displays was investigated in 3- and 6-month-old infants, as well as in adults, through a modified version of the visual search paradigm and the recording of eye movements. Participants (N = 43) were shown 32 visual displays that comprised a target face among 3 or 5 heterogeneous objects as distractors. Results demonstrated that faces captured and maintained adults’ and 6-month-olds’ attention, but not 3-month-olds’ attention. Overall, the current study contributes to knowledge of the capacity of social stimuli to attract and maintain visual attention over other complex objects in young infants as well as in adults.

► We investigated whether a face grabs and maintains infants’ and adults’ attention.
► Faces among objects grab and maintain adults’ and 6-month-old infants’ attention.
► Human faces have a detection advantage among objects in infancy.
