Brain-to-brain synchrony and attachment
Within a large international team of investigators from across Europe, my colleagues Trinh Nguyen, Melanie Kungl, Stefanie Hoehl, Lars White and I set out to investigate how exactly parent-child bio-behavioural synchrony is linked to attachment.
We invited parent-child pairs – 140 parents and their 5-to-6-year-old kids – to the Social Neuroscience of Human Attachment Lab where they solved Chinese tangram puzzles together.
We measured brain activity with functional near-infrared spectroscopy "hyperscanning", for which parents and children were asked to wear caps linked up with optical sensors. We also recorded videos of their interactions so we could assess how much behavioural synchrony they demonstrated – how attuned and attentive they were to each other. And finally, we assessed parents' and children's type of attachment – known
