The more eye contact mothers make with their baby, the better their brainwaves synchronize with one another, a new study shows.
When parents and infants interact, their gaze, emotions and heart rate synchronize. But until now, little has been known about whether brain activity also lines up.
Researchers found that direct eye contact not only aligns the brainwaves but causes infants to vocalize more, showing an intention to communicate.
This knowledge can help improve communication between parents and infants, making learning more effective during this critical time in a child’s brain development, researchers said.
