Children's inferences of moral character across different moral subdomains.

Adults use an individual's behavior in one moral subdomain to make inferences about how they will act in another moral subdomain, reflecting a tendency to attribute underlying traits to individuals. We recruited 4- to 7-year-old children from a large city in North America to investigate their ability to generalize from one moral subdomain to another and integrate these pieces of information to form trust and friendship decisions, focusing on the subdomains of helping and fairness, given their centrality to moral cognition. In Experiment 1 (N = 131; 49% female; 38% White), children watched a protagonist help or hinder another person with their goal and then engage in either a fair or an unfair resource distribution between two novel recipients; in Experiment 2 (N = 130; 52% female; 55% White), these events were reversed. We recorded the children's surprise at the second event and their willingness to trust subsequent information provided by the protagonist and to befriend her. Children selectively generalized from the initial behavior, reporting greater surprise to fair (vs. unfair) behavior after the protagonist hindered and greater surprise to the protagonist helping (vs. hindering) after she distributed resources unfairly previously. Moreover, the presence of a single moral transgression lowered children's trust and friendship judgments to chance levels. These findings demonstrate that moral transgressions (vs. moral adherence to moral norms) provide a basis for guiding children's subsequent expectations for future behavior across moral subdomains, as well as for forming social decisions regarding whether to befriend and trust individuals, for children as young as age 4 years.

Generalizing across moral sub-domains: infants bidirectionally link fairness and unfairness to helping and hindering.

Across two experiments, we investigated whether infants use prior behavior to form expectations about future behavior within the moral domain, focusing on the sub-domains of fairness and help/harm. In Experiment 1, 14- to 27-month-old infants were familiarized to an agent who either helped or hindered another agent to obtain her goal. At test, infants saw the helper or hinderer perform either a fair or unfair distribution of resources to two recipients. Infants familiarized to helping looked longer to the unfair distribution than the fair distribution at test, whereas infants familiarized to hindering looked equally at both test events, suggesting that hindering led infants to suspend baseline expectations of fairness. In Experiment 2, infants saw these events in reverse. Following familiarization to fair behavior, infants looked equally to helping and hindering; in contrast, following familiarization to unfair behavior, infants looked significantly longer to helping than hindering on test, suggesting that prior unfair behavior led infants to expect the agent to hinder another agent's goals. These results suggest that infants utilize prior information from one moral sub-domain to form expectations of how an individual will behave in another sub-domain, and that this tendency seems to manifest more strongly when infants initially see hindering and unfair distributions than when they see helping and fair distributions. Together, these findings provide evidence for consilience within the moral domain, starting by at least the second year of life.
