From: Gaze onsets during naturalistic infant-caregiver interaction associate with ‘sender’ but not ‘receiver’ neural responses, and do not lead to changes in inter-brain synchrony

Figure 1

Illustration of experimental set-up and design for event locked analysis. (A) shows screenshots of experimental recordings from three camera angles used. (B) shows event locking process for sender and receiver EEG activity relative to mutual gaze onsets. Here receiver’s gaze was maintained on the sender and the sender’s gaze shifted from looking at the puppet/inattention toward looking at the receiver, facilitating mutual gaze. ± 1 s of EEG activity was extracted around gaze shift. (C) shows topographical illustration of sender’s and receiver’s gaze relative to mutual and non-mutual gaze onsets. (D) shows event locking process for sender and receiver EEG activity relative to mutual gaze onsets. Here receiver’s gaze was maintained on either the puppet (or inattention) and the sender’s gaze shifted from looking at the puppet/inattention toward looking at the receiver, facilitating non-mutual gaze. ± 1 s of EEG activity was extracted around gaze shift.
