Insights
Infants gradually shift attention to faces in complex scenes between 3 and 9 months. Early attention relies on image features, later focusing on faces, indicating developmental changes in visual processing.
Area of Science:
- Developmental psychology
- Cognitive neuroscience
- Visual attention
Background:
- Newborns show innate preference for faces.
- Development of face attention in complex naturalistic scenes is not well understood.
Purpose of the Study:
- Investigate the developmental trajectory of infant attention to faces.
- Examine how attention shifts from low-level image features to faces in complex scenes.
Main Methods:
- Eye-tracking methodology was used to record infant and adult gaze patterns.
- Participants viewed clips from "A Charlie Brown Christmas" during free-viewing.
- Novel computational tools analyzed fixation consistency and predictors.
Main Results:
- Face-looking tendency increased with age from 3 to 9 months.
- 3-month-olds showed less consistent attention and were driven by image salience.
- Attention gradually shifted towards faces between 3 and 9 months.
Conclusions:
- Infant attention to faces develops significantly between 3 and 9 months.
- Early visual attention is guided by low-level features, maturing to prioritize faces.
- This developmental shift has implications for social development and attentional control.
Abstract:
In simple tests of preference, infants as young as newborns prefer faces and face-like stimuli over distractors. Little is known, however, about the development of attention to faces in complex scenes. We recorded eye-movements of 3-, 6-, and 9-month-old infants and adults during free-viewing of clips from A Charlie Brown Christmas (an animated film). The tendency to look at faces increased with age. Using novel computational tools, we found that 3-month-olds were less consistent (across individuals) in where they looked than were older infants. Moreover, younger infants' fixations were best predicted by low-level image salience, rather than the locations of faces. Between 3 and 9 months of age, infants gradually focused their attention on faces. We discuss several possible interpretations of this shift in terms of social development, cross-modal integration, and attentional/executive control.

The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
