People accept breaks in the causal chain between crime and punishment.

Crime and punishment are usually connected. An agent intentionally causes harm, other people find out, and they punish the agent in response. We investigated whether people care about the integrity of this causal chain.

Are Real-World Prosociality Programs Associated with Greater Psychological Well-Being in Primary School-Aged Children?

Quality education can build a sustainable, happier world, but what experiences support student well-being? Numerous laboratory studies suggest that prosocial behavior predicts greater psychological well-being. However, relatively little work has examined whether real-world prosociality programs are associated with greater well-being in primary school-aged children (aged 5-12). In Study 1, we surveyed 24/25 students who completed their 6th Grade curriculum in a long-term care home alongside residents called "Elders," which offered numerous opportunities for planned and spontaneous helping.

Preschoolers Focus on Others' Intentions When Forming Sociomoral Judgments.

Many studies suggest that preschoolers initially privilege outcome over intention in their moral judgments. The present findings reveal that, in contrast, even younger preschoolers can privilege intentions when evaluating characters who successfully or unsuccessfully help or hinder a third party in achieving its goal. Following a live-action puppet show originally created for infant populations, children made a forced-choice social judgment (which puppet was liked) and two forced-choice moral judgments (which puppet was nicer, which puppet should be punished), and were asked to explain their punishment allocations.

Feeling out a link between feeling and infant sociomoral evaluation.

Recent research has shown that infants selectively approach prosocial versus antisocial characters, suggesting that foundations of sociomoral development may be present early in life. Despite this, to date, the mental processes involved in infants' prosocial preferences are poorly understood. To explore a possible role of emotions in early social evaluations, the current studies examined whether four samples of infants and toddlers express different emotional reactions after observing prosocial (giving) versus antisocial (taking) events.

Selectivity in toddlers' behavioral and emotional reactions to prosocial and antisocial others.

Whereas some evidence suggests that toddlers consider targets' deservingness when deciding whom to help, other research demonstrates that toddlers help indiscriminately. The present findings shed light on this discrepancy by demonstrating that although toddlers do exhibit selectivity in giving behaviors, their emotional responses are comparatively indiscriminate. Specifically, in Experiment 1, 20-month-olds (N = 64) were more likely to give preferred toys to prosocial versus antisocial puppets, and more likely to withhold toys from antisocial versus prosocial puppets.

The early emergence of sociomoral evaluation: infants prefer prosocial others.

Humans readily evaluate third-parties' prosocial and antisocial acts. Recent evidence reveals that this tendency emerges early in development-even preverbal infants selectively approach prosocial others and avoid antisocial ones. Rather than reflecting attraction toward or away from low-level characteristics of the displays or simple behavioral rules, infants are sensitive to characteristics of both the agents and recipients of prosocial and antisocial acts.

Positive feelings reward and promote prosocial behavior.

Humans are extraordinarily prosocial. What inspires and reinforces a willingness to help others? Here we focus on the role of positive feelings. Drawing on functional accounts of positive emotion, which suggest that positive emotional states serve to alert actors to positive experiences and encourage similar action in the future, we summarize evidence demonstrating that positive feelings promote and reward prosocial behavior throughout development.

Preschoolers' social and moral judgments of third-party helpers and hinderers align with infants' social evaluations.

Two experiments explored preschoolers' social preferences and moral judgments of prosocial and antisocial others. In Experiment 1, 3- to 5-year-olds (N=74) observed helping and hindering scenarios previously used to explore sociomoral evaluation in preverbal infants. Whereas 3-year-olds in Experiment 1 did not reliably distinguish between the helper and hinderer when reporting social preferences or moral judgments, both 4- and 5-year-olds preferred the helper, judged the helper to be "nicer" than the hinderer, selectively allocated punishment to the hinderer, and were able to justify their punishment allocations.

Children's judgments about ownership rights and body rights: Evidence for a common basis.

We report two experiments supporting the theory that children's understanding of ownership rights is related to their notions of body rights. Experiment 1 investigated 4- to 7-year-olds' (N=123) developing sensitivity to physical contact in their judgments about the acceptability of behaving in relation to owned objects and body parts. Experiment 2 used a simpler design to investigate this in 3- and 4-year-olds (N=112).

Young children remedy second- and third-party ownership violations.

When responding to ownership violations, children can focus on the victim's needs, the perpetrator's punishment, or both. Recent studies show that 3- and 5-year-olds are equally likely to respond to second- and third-party violations, and 3-year-olds return objects to their rightful owners. Children's interventions are consistent with justice for victims.

Prosocial behavior leads to happiness in a small-scale rural society.

Humans are extraordinarily prosocial, and research conducted primarily in North America indicates that giving to others is emotionally rewarding. To examine whether the hedonic benefits of giving represent a universal feature of human behavior, we extended upon previous cross-cultural examinations by investigating whether inhabitants of a small-scale, rural, and isolated village in Vanuatu, where villagers have little influence from urban, Western culture, survive on subsistence farming without electricity, and have minimal formal education, report or display emotional rewards from engaging in prosocial (vs. personally beneficial) behavior.

Parallels in preschoolers' and adults' judgments about ownership rights and bodily rights.

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 parts.

Preschoolers can infer general rules governing fantastical events in fiction.

Young children are frequently exposed to fantastic fiction. How do they make sense of the unrealistic and impossible events that occur in such fiction? Although children could view such events as isolated episodes, the present experiments suggest that children use such events to infer general fantasy rules. In 2 experiments, 2- to 4-year-olds were shown scenarios in which 2 animals behaved unrealistically (N = 78 in Experiment 1, N = 94 in Experiment 2).

First possession, history, and young children's ownership judgments.

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 from first possession; the experiments instead support an alternative account according to which the first possession bias reflects children's historical reasoning.

Artifacts and natural kinds: children's judgments about whether objects are owned.

People's behavior in relation to objects depends on whether they are owned. But how do people judge whether objects are owned? We propose that people expect human-made objects (artifacts) to be more likely to be owned than naturally occurring objects (natural kinds), and we examine the development of these expectations in young children. Experiment 1 found that when shown pictures of familiar kinds of objects, 3-year-olds expected artifacts to be owned and inanimate natural kinds to be non-owned.
