Sequence of action in the two false belief conditions FB1 and FB2. In condition FB1, the agent observed how a bear puppet transferred a ball from the left to the right box, but turned away while the bear then removed the ball from the scene. In condition FB2, the agent turned away before the bear transferred the ball from the left to the right box, and only turned back after the bear had removed the ball from the scene. The two conditions respectively controlled for simpler non-belief related strategies, such as, gazing at the first or last box the ball had been in.
