Figure 2

A cartoon depiction for each step of Experiment I's sequence is shown.

(a) During the recording session, the participant was invited into the room and received instructions about the experiment. During this time, everything was recorded for the Doppelgänger scene. (b) Normal Question scene. After the covert substitution from the live scene to the recorded scene, the participant replied naturally to the experimenter, indicating that the substitution was successful. (c) Doppelgänger scene. The participant saw himself, thereby realising that the scene he had experienced was not live. (d) Fake Live scene. The SR system worked even after the Doppelgänger scene. Seven of 10 participants could not detect that the given scene was recorded. (e) The Live scene after the Fake Live scene. The participant was not certain whether he was experiencing live or recorded scenes any more. See DISCUSSION. Colour bars at the right of each box indicate scene differentiation (orange for a live scene and green for a recorded scene). For convenience, the microphone and connection cables are omitted from the drawings.
