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.

Cooperative societies rely on reward and punishment for norm enforcement. We examined the developmental origin of these interventions in the context of distributive fairness: past research has shown that infants expect resources to be distributed fairly, prefer to interact with fair distributors, and evaluate others based on their fair and unfair resource allocations. In order to determine whether infants would intervene in third-party resource distributions by use of reward and punishment we developed a novel task. Sixteen-month-old infants were taught that one side of a touch screen produces reward (vocal statements expressing praise; giving a cookie), whereas the other side produces punishment when touched (vocal statements expressing admonishment; taking away a cookie). After watching videos in which one actor distributed resources fairly and another actor distributed resources unfairly, participants' screen touches on the reward and punishment panels while the fair and unfair distributors appeared on screen were recorded. Infants touched the reward side significantly more than the punishment side when presented with the fair distributor but touched the screen sides equally when the unfair distributor was shown. Control experiments revealed no evidence of reward or punishment when infants saw food items they liked and disliked, or individuals uninvolved in the resource distribution events. These results provide the earliest evidence that infants are able to spontaneously intervene in socio-moral situations by rewarding positive actions., (Copyright © 2021 Elsevier B.V.

The ability to distinguish between mere equality in resource distributions and fairness based on a broader range of contextual factors is of paramount importance in social decision making and is a critical component of morality. Children's developmental shift from viewing inequality as a dichotomous moral issue toward a more nuanced understanding of partial inequality has been well documented across middle childhood and is attributed to a host of potential theoretical underpinnings, including developing number concept, increased regard for one's social status, and a maturing concept of fairness. The current study examined the electrophysiological markers associated with children's (N = 83; 4 to 8 years of age) third-party evaluations of equal, slightly unequal, and extremely unequal resource distributions, documenting the timing of fairness considerations. It further explored the link between individual differences in these neural computations and children's allocation behaviors and judgments. Event-related potentials demonstrated an early differentiation between equality and any type of inequality reflected by a medial frontal negativity. Later (after 500 ms), extreme inequality was discriminated from equality and slight inequality. Differences in later waveforms predicted sharing and third-party contextual resource distributions, accounting for wealth and merit. These results illuminate the multifaceted nature of developing neural computations of fairness and illustrate the value of a multiple levels of analysis approach in contributing theoretical clarity toward the developmental science of moral cognition and behavior.

Concerns about fairness are central to mature moral judgments. We review research regarding the origins of a sensitivity to distributive fairness, and how it relates to early sharing. Infants' sensitivity to fairness appears to be commensurate with that of school-age children: infants notice violations to fairness norms and evaluate individuals based on their fair or unfair behavior. However, it may differ in other ways: there is no evidence that infants punish unfair individuals. Sharing behavior plays a role in both the developmental emergence of, and subsequent individual differences in, infants' fairness concerns. These results motivate novel questions, such whether infants can entertain other models of fairness, whether infants' socio-moral concerns hang together, and the relationship early fairness sensitivities and later fair behavior., (Copyright © 2018 Elsevier Ltd.

The ability to reason about fairness plays a defining role in the development of morality. Thus, researchers have long been interested in understanding when and how a sensitivity to fairness first develops. Here, we examined infants' ability to use fairness information in selecting social partners. Using a novel experimental paradigm that combined pre-recorded stimuli with an active behavioral measure, we tested whether infants preferred to socially engage with an individual they had previously seen behave fairly or unfairly. After viewing an individual distribute goods to third parties either equally (i.e., 3:3 distribution) or unequally (i.e., 5:1 distribution), both 13- and 17-month-old infants selectively chose to engage in a social interaction with (i.e., take a toy from) an individual who distributed resources equally. The use of a novel paradigm to assess infants' fairness preferences demonstrates that infants' previously established fairness preferences extend across different, more demanding paradigms, and may therefore be more enduring in nature. Together, these findings provide new insights into the nature of infants' fairness representations, and fill in key gaps in the developmental timeline of infants' ability to use fairness information in their consideration of potential social partners. In sum, these findings build on previous research by demonstrating that infants not only hold an expectation that resources should be distributed fairly, they also preferentially interact with those who have previously done so. The early-emerging ability to both reason about and use fairness information may play an influential role in the development of complex prosocial behaviors related to morality more broadly.

The present research investigated the developmental trajectory of infants' fairness expectations from 6 to 15 months of age (N = 150). Findings revealed a developmental transition in infants' fairness expectations between 6 and 12 months, as indicated by enhanced visual attention to unfair outcomes of resource distribution events (a 3:1 distribution) relative to fair outcomes (a 2:2 distribution). The onset of naturalistic sharing behavior predicted infants' fairness expectations at transitional ages. Beyond this period of developmental transition, the presence of siblings and infants' prompted giving behavior predicted individual differences in infants' fairness concerns. These results provide evidence for the role of experience in the acquisition of fairness expectations and reveal early individual differences in such expectations., (© 2016 The Authors.
