Developmental changes in attention to faces and bodies in static and dynamic scenes

Area of Science:

• Developmental Psychology
• Cognitive Neuroscience
• Social Perception

Background:

• Typical visual development shows a strong preference for faces, potentially limiting attention to other scene elements.
• Understanding attentional mechanisms for real people in naturalistic scenes is crucial for developmental insights.

Purpose of the Study:

• To investigate the development of attentional mechanisms in typical individuals viewing naturalistic scenes with people.
• To examine how static vs. dynamic stimuli and single vs. multiple characters influence gaze behavior.

Main Methods:

• Eye-tracking was used to record the looking behaviors of children, adolescents, and young adults.
• Participants viewed static and dynamic scenes containing one or more people.

Main Results:

• A general bias towards attending to faces over other scene parts was observed across age groups.
• Motion cues reduced face fixation frequency but increased duration in single-person scenes.
• Multiple characters and motion attenuated face-bias, leading to shifts towards bodies or off-screen glances, especially in children.

Conclusions:

• Children exhibit heightened sensitivity to motion and scene complexity, suggesting difficulty processing dynamic faces and managing divided attention.
• Gaze strategies in children viewing complex social scenes may serve to reduce cognitive and affective load.
• Findings offer novel insights into the development of social attention during naturalistic scene perception.
