Visible Eyes Switched the Learning Signal On
Infants learned a made-up language only when they could see the speaker's eyes, and brain-to-brain coupling predicted the result.
Summary
Infants learned a made-up language only when they could see the speaker's eyes, and brain-to-brain coupling predicted the result.
Cambridge and Nanyang Technological University researchers showed videos of one speaker presenting three artificial languages to 42 infants in the United Kingdom and Singapore. Clear, shaded or opaque glasses changed whether her eyes were visible. The infants learned only the language paired with visible eyes, and adult-to-infant neural coupling predicted learning better than the infants' brain activity alone. The small controlled study supports eye contact as a social selection cue, not a universal prescription for every child or culture.
Why it matters
Infants learned a made-up language only when they could see the speaker's eyes, and brain-to-brain coupling predicted the result.
Limits and context
- The infants learned only the language paired with visible eyes, and adult-to-infant neural coupling predicted learning better than the infants' brain activity alone.
