This prospective, longitudinal study examined associations between whether and when children first acquire a mobile phone and their adjustment measures, among low-income Latinx children. Children (N = 263; 55% female; baseline M[subscript age] = 9.5) and their parents were assessed annually for 5 years from 2012. Children first acquired a mobile…

An object's mental representation includes not just visible attributes but also its nonvisible history. The present studies tested whether preschoolers seek subtle indicators of an object's history, such as a mark acquired during its handling. Five studies with 169 children 3-5 years of age and 97 college students found that children (like adults)…

This study provides evidence that children give priority to ownership when judging who should use an object. Children (N = 269) and adults (N = 154) considered disputes over objects. 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…

It is impossible to perceive who owns an object; this must be inferred. One way that children make such inferences is through a first possession bias--when two agents each use an object, children judge the object belongs to the one who used it first. Two experiments show that this bias does not result from children directly inferring ownership…

To examine early developments in other-oriented resource sharing, fifty-one 18- and 24-month-old children were administered 6 tasks with toys or food that could be shared with an adult playmate who had none. On each task the playmate communicated her desire for the items in a series of progressively more explicit cues. Twenty-four-month-olds…

For adults, ownership is nonobvious: (a) determining ownership depends more on an object's history than on perceptual cues, and (b) ownership confers special value on an object ("endowment effect"). This study examined these concepts in preschoolers (2.0-4.4) and adults (n = 112). Participants saw toy sets in which 1 toy was designated as the…

Children between three and five years of age were told or shown that story characters held beliefs that differed from their own beliefs concerning physical facts, moral values, social conventions, personal values, and ownership. Found that three year olds had difficulty attributing to others beliefs that differed from their own. (BC)
