It is about sharing an intention to communicate

According to a new research, when a parent and baby interacts, various aspects of their behavior can synchronize especially their brain activity.

Brainwaves reflect the gathering level action of a huge number of neurons and are associated with data exchange between cerebrum districts. Scientists at the University of Cambridge conducted a study to identify whether eye-contact with babies can synchronize adult’s brainwaves.

Scientists conducted the study on 36 infants. They examined their brainwaves patterns using electroencephalography (EEG), Next, they compared the infants’ brain activity to that of the adult who was singing nursery rhymes to the infant.

In the first of two experiments, the infant watched a video of an adult as she sang nursery rhymes. First, the adult – whose brainwaves patterns had already been recorded – was looking directly at the infant. Then, she turned her head to avert her gaze, while still singing nursery rhymes. Finally, she turned her head away, but her eyes looked directly back at the infant.

Scientists found that infant’s brainwaves were more synchronized to the adults. At the point when the adult’s gaze met the infant’s when contrasted with when her look was deflected. Interestingly, the best synchronizing impact happened when the adult’s head was dismissed yet her eyes still took a gander at the newborn child.

This may be due to a look shows up profoundly consider, thus gives a more grounded flag to the newborn child that the grown-up means to speak with her.

During another experiment, both infants and adults became more synchronized to each other’s brain activity when mutual eye contact was established. This occurred even though the adult could see the infant at all times, and infants were equally interested in looking at the adult even when she looked away.

Means, brain-wave synchronization isn’t just due to seeing a face or finding something interesting, but about sharing an intention to communicate.

Scientists found that infant’s more likely to make a greater effort to communicate. When the adult made direct eye contact – and individual infants who made longer vocalizations also had higher brainwaves synchrony with the adult.

Dr. Victoria Leong, lead author on the study said, “When the adult and infant are looking at each other, they are signaling their availability and intention to communicate with each other. We found that both adult and infant’s brains respond to a gaze signal by becoming more in sync with their partner. This mechanism could prepare parents and babies to communicate, by synchronizing when to speak and when to listen, which would also make learning more effective.”

Dr. Sam Wass, the last author of the study, said, “We don’t know what it is, yet, that causes this synchronous brain activity. We’re certainly not claiming to have discovered telepathy! In this study, we were looking at whether infants can synchronize their brains to someone else, just as adults can. And we were also trying to figure out what gives rise to the synchrony.”

“Our findings suggested eye gaze and vocalizations may both, somehow, play a role. But the brain synchrony we were observing was at such high time-scales – of three to nine oscillations per second – that we still need to figure out how exactly eye gaze and vocalizations create it.”
