The conditions included Dynamic and Static Scenes (top row), Dynamic and Static Objects (middle row), and Dynamic and Static Faces (bottom row). The Dynamic Scene stimuli consisted of 3-s video clips of first-person perspective motion through scenes. The Static Scene stimuli consisted of 3 still images taken from these same video clips, each presented for 1 s and in a random order such that first-person perspective motion could not be inferred. The Dynamic Object stimuli consisted of 3-s video clips of moving toys presented against a black background, while the Dynamic Face stimuli consisted of 3-s video clips of only the faces of children against a black background as they laughed, smiled, and looked around, while. The Static Object and Static Face stimuli were created following the same procedure described for the Static Scene stimuli.
