“…As the building blocks of social cognition emerge early on in human development, hyperscanning has gained momentum among developmental researchers in recent years. Hyperscanning studies involving developmental populations have addressed a variety of social exchanges including interactions between infants and adults using EEG ( Leong et al, 2017 , Leong et al, 2019 , Perone et al, 2020 , Santamaria et al, 2020 , Wass et al, 2018 ) and functional near-infrared spectroscopy (fNIRS; Nguyen et al, 2020 , Nguyen et al, 2021 ; Piazza et al, 2020 ); interactions between children and adults using EEG ( Bevilacqua et al, 2019 ), magnetoencephalography (MEG; Hasegawa et al, 2016 ; Hirata et al, 2014 ) and fNIRS ( Azhari et al, 2019 , Hoyniak et al, 2021 , Kruppa et al, 2021 , Miller et al, 2019 , Quiñones‐Camacho et al, 2020 , Reindl et al, 2018 , Reindl et al, 2021 ); and interactions between child and adolescent peers using EEG ( Dikker et al, 2017 , Dikker et al, 2021 ) and fNIRS ( Piazza et al, 2021 ).…”
