Seeing the face through the eyes: a developmental perspective on face expertise

Area of Science:

• Developmental psychology
• Cognitive neuroscience
• Social cognition

Background:

• Face recognition is a crucial human skill.
• Infants show a specific attention bias towards faces, particularly the eyes.
• Understanding the developmental origins of face recognition is key to cognitive science.

Purpose of the Study:

• To propose and review evidence for a developmental bias in infants' attention towards eyes.
• To explain the special status of face recognition in individual identification.
• To explore the link between eye attention, face recognition, and communicative functions.

Main Methods:

• Review of existing neuroimaging studies.
• Analysis of research on developmental disorders, including autism spectrum disorder.
• Synthesis of evidence on infant attention biases.

Main Results:

• Infants and children exhibit a strong attentional bias towards the eyes of others.
• This bias is proposed to be a key factor in developing expertise in face recognition.
• Evidence from neuroimaging and developmental disorders supports this attentional bias hypothesis.

Conclusions:

• The developmental bias towards attending to eyes is fundamental to human face recognition.
• The communicative functions of eye gaze likely drive this early attentional preference.
• This bias plays a critical role in social interaction and individual differentiation.
