Schematic drawing of the test trials in Experiment 1. False-belief condition: The points-left test trial in the false-belief condition was identical to the left-container familiarization trial in the same condition, except that the experimenter moved the toy to the right container while she counted aloud. In the points-right test trial, the agent pointed to the right container in the final phase of the trial. Knowledge condition: The agent remained present throughout the knowledge condition test trials: instead of opening and closing the green curtain, she moved the open curtain from one side of her window to the other. Ignorance condition: The ignorance condition test trials were identical to those in the false-belief condition with one exception: in each test trial, after placing the toy into the left container, the experimenter immediately took it out again. After the agent closed the green curtain, the experimenter hid the toy in the right container while she counted aloud.
