Although people take care of their own possessions, they also engage in stewardship and take care of things they do not own. Here, we examined what young children infer when they observe stewardship behavior of an object. Through four experiments on predominantly middle-class Canadian children (total N = 350, 168 girls and 182 boys from a…

The ability to anticipate the future improves significantly across the preschool years. Whereas 5-year-olds understand that they will prefer adult items in the future, 3-year-olds indicate they will continue to prefer child items. We explore these age-related changes in future-oriented cognition by comparing children's inferences about their…

Group ownership is ubiquitous-property is owned by countries, corporations, families, and clubs. However, people cannot understand group ownership by simply relying on their conceptions of ownership by individuals, as group ownership is subject to complexities that do not arise when property is individually owned. We report 6 experiments…

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 examined children's understanding of how ownership affects object use. In Experiment 1, 84 children age 4-6 were asked what a person was allowed to do with a human-made object that either belonged to the person or belonged to someone else. In Experiment 2, 44 children age 4-5 were asked what a person was allowed to do with a…

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…

How is ownership established over non-owned things? We suggest that people may view ownership as a kind of credit given to agents responsible for making possession of a non-owned object possible. On this view, judgments about the establishment of ownership depend on attributions of responsibility. We report three experiments showing that people's…

Understanding ownership rights is necessary for socially appropriate behavior. We provide evidence that preschoolers' and adults' judgments of ownership rights are related to their judgments of bodily rights. Four-year-olds (n = 70) and adults (n = 89) evaluated the acceptability of harmless actions targeting owned property and body…

In everyday life, we are often faced with the problem of judging who owns an object. The current experiments show that children and adults base ownership judgments on group stereotypes, which relate kinds of people to kinds of objects. Moreover, the experiments show that reliance on stereotypes can override another means by which people make…

Appropriate behavior in relation to an object often requires judging whether it is owned and, if so, by whom. The authors propose accounts of how people make these judgments. Our central claim is that both judgments often involve making inferences about object history. In judging whether objects are owned, people may assume that artifacts (e.g.,…

Owners control permission--they forbid and permit others to use their property. So it is reasonable to assume that someone controlling permission over an object is its owner. The authors tested whether preschoolers infer ownership in this way. In the first experiment, 4- and 5-year-olds, but not 3-year-olds, chose as owner of an object a character…

Within psychology, most aspects of ownership have received scant attention or have been overlooked completely. In this chapter, the authors outline 21 reasons why it will be important (and interesting) to understand the psychological basis of ownership of property, including its developmental origins: (1) Daily life; (2) A human universal, and…

A basic problem of daily life is determining who owns what. One way that people may solve this problem is by relying on a "first possession" heuristic, according to which the first person who possesses an object is its owner, even if others subsequently possess the object. We investigated preschoolers' use of this heuristic in five experiments. In…
