 In 2005, this developmental timeline was called into question. Kristine Onishi and Renée Baillargeon (2005) published the result of a non-verbal version of the false belief task, which they administered to 15-month old infants. The experiment involves three steps. First, the infants see a toy between two boxes, one yellow and one green, and then an actor hiding the toy inside the green box. Next, the infants see the toy sliding out of the green box and hiding inside the yellow box. In the true belief condition (TB), the actor notices that the toy changes location, while in the false belief condition (FB) she does not. Finally, half of the infants see the actor reaching into the green box, while the other half sees the actor reaching into the yellow box. According to the violation-of-expectation paradigm, infants reliably look for a longer time at unexpected events. Therefore, if the infants expected the actor to search for the toy on the basis of the actor’s belief about its location, then when the actor had a true belief that the toy was hidden in one box, the infants should look longer when the actor reached into the other box instead. Conversely, the infants should look longer at one box when the actor falsely believed that the toy was hidden in the other box. Strikingly, these predictions were confirmed in both the (TB) and (FB) conditions. On this basis, Onishi and Baillargeon (2005) concluded that children of 15 months possess the capacity to represent others’ false beliefs.
