title: I know you see it wrong! Children use others' false perceptions to predict their behaviors.
abstract: Research on children's ability to attribute false mental states to others has focused exclusively on false beliefs. We developed a novel paradigm that focuses instead on another type of false mental state: false perceptions. From approximately 4years of age, children begin to recognize that their perception of an illusory object can be at odds with its true properties. Our question was whether they also recognize that another individual viewing the object will similarly experience a false perception. We tested 33 preschool children with a task in which distorting lenses caused a small object to appear large and a large object to appear small. To succeed, children needed to recognize that a naive agent would falsely perceive the relative size of the objects and to correctly anticipate the agent's actions on that basis. Children performed significantly better than chance in our false perception test, and there was a developmental progression in performance from 4 to 5years of age similar to that seen in standard false belief tests. Our findings demonstrate that preschool children are capable of understanding that other individuals will be perceptually misled by illusory objects and that these false perceptions will influence their actions in predictable ways.
