Infant sensitivity to adult eye direction
Child Development
|October 1, 1996
Summary
Infants respond to adult eye contact by smiling and attending. When adults averted their gaze, infant smiling decreased, indicating early social-communication skills development.
Area of Science:
- Developmental Psychology
- Infant Social Cognition
- Face Perception
Background:
- Infant social-communication relies on understanding gaze.
- Existing models of infant face perception and theory of mind need empirical validation.
Purpose of the Study:
- To investigate how infant social-communication, specifically smiling and visual attention, is affected by adult eye contact.
- To examine the role of contingent social interaction in early development.
Main Methods:
- Adults manipulated eye contact (direct vs. averted) during interactions with 3-6 month-old infants.
- Experiments were conducted both in-person and via closed-circuit television.
- Infant smiling and visual attention were recorded during 1-minute interaction periods.
Main Results:
- Experimental infants' smiling significantly declined when adult eye contact was averted.
- Infant visual attention decreased across interaction periods when eye contact was manipulated.
- Control infants, receiving continuous eye contact, showed stable gaze and smiling.
Conclusions:
- Infant social-communication is highly sensitive to adult gaze direction.
- Findings support theories on infant face perception and the development of theory of mind.
- Contingent social interaction is crucial for early social-emotional development.
