Example stimuli used in the experimental scans. The conditions included A) Dynamic Scenes, which consisted of 3-s video clips of first-person perspective motion through a scene; B) Static Scenes, which consisted of 3 1-s stills taken from the Dynamic Scenes condition and presented in a random order, such that first-person perspective motion could not be inferred; C) Dynamic Faces, which consisted of 3-s video clips of only the faces of children against a black background as they interacted with off-screen adults or toys; and D) Static Faces, which consisted of 3 1-s stills taken from the Dynamic Faces and presented in a random order.
