Hypothesis
Infants would show cortical activity differentiating between mutual and averted gaze during face-to-face communication in brain regions similar to those activated in adults.
Conclusion
The study found that four-month-old infants activate brain regions associated with facial communication cues, similar to adults.
Supporting Evidence
- Infants showed increased brain activity in response to mutual gaze compared to averted gaze.
- The right superior posterior temporal cortex and right fronto-polar cortex were identified as key areas activated during the study.
- Results suggest that infants have an early specialization for processing facial communication cues.
Takeaway
Babies' brains light up when they see someone looking at them, just like adults' brains do.
Methodology
The study used near-infrared spectroscopy and electroencephalography to measure brain activity in response to mutual and averted gaze in infants.
Limitations
The study's findings may not generalize beyond the specific age group and conditions tested.
Participant Demographics
The sample consisted of 12 four-month-old infants, including five girls.
