In disputes between a character using an object and the owner of the object, children, as young as 3 years and as old as 7 years, sided with the owner, and did so…

Two experiments provide evidence that preschoolers selectively infer history when explaining outcomes and infer past events that could have plausibly happened. In Experiment 1, thirty-three 3-year-olds and thirty-six 4-year-olds explained why a character owns or likes certain objects. In Experiment 2, thirty-four 4-year-olds and thirty-six…

On each task the playmate communicated her desire for the items in a series of progressively more explicit cues. Twenty-four-month-olds…
