Trusting young children to help causes them to cheat less.

Trust and honesty are essential for human interactions. Philosophers since antiquity have long posited that they are causally linked. Evidence shows that honesty elicits trust from others, but little is known about the reverse: does trust lead to honesty? Here we experimentally investigated whether trusting young children to help can cause them to become more honest (total N = 328 across five studies; 168 boys; mean age, 5.94 years; s.d., 0.28 years). We observed kindergarten children's cheating behaviour after they had been entrusted by an adult to help her with a task. Children who were trusted cheated less than children who were not trusted. Our study provides clear evidence for the causal effect of trust on honesty and contributes to understanding how social factors influence morality. This finding also points to the potential of using adult trust as an effective method to promote honesty in children.

Young children's conceptualization of empirical disagreement.

Chinese and American children aged 5-11 years (total N = 144) heard two child informants make conflicting empirical claims about each of 4 scenarios. For example, one informant claimed that a ball would float when dropped in water whereas the other informant claimed that it would sink. Children were asked to judge whether each informant could be right, and to justify their overall judgment. In both samples, there was a change with age. Older children often said that each informant could be right whereas younger children, especially in China, were more likely to say that only one informant could be right. Nevertheless, in the wake of decisive empirical evidence (e.g., the ball was shown to sink when dropped in water), almost all children, irrespective of age, drew appropriate conclusions about which of the two informants had been right. Thus, with increasing age, children differ in their prospective - but not in their retrospective - appraisal of empirical disagreement. Absent decisive evidence, older children are more likely than younger children to suspend judgment by acknowledging that either of two conflicting claims could be right. We argue that children's tendency to suspend judgment is linked to their developing awareness of empirical uncertainty, as expressed both in the justifications they give when judging the disagreement and in their own beliefs about the scenarios. Implications for children's understanding of disagreement are discussed.

Chinese parents' support of preschoolers' mathematical development.

Research has documented the critical role played by the early home environment in children's mathematical development in Western contexts. Yet little is known about how Chinese parents support their preschoolers' development of math skills. The Chinese context is of particular interest because Chinese children outperform their Western counterparts in math, even early in development. The current study sought to fill this gap by examining a sample of 90 families of 4- and 5-year-olds from mainland China. Parental support-as measured by the frequency of parent-child engagement in home activities as well as parent number talk-and parents' role in children's numeracy skills were investigated. Results indicate wide variation among parents in both types of support. Frequency of engagement in formal numeracy activities, including counting objects and reading number story books, was related to children's knowledge of cardinality. A principal components analysis did not identify informal numeracy activities as a distinct home activity component, likely due to the infrequent occurrences of game-like numeracy activities among the Chinese families. Instead, a structured activity component emerged (e.g., playing musical instruments) and was positively related to children's arithmetic skills. Diversity, but not quantity, of parent number talk was related to children's symbolic magnitude understanding. The distinctive relationships between specific parental measures and child outcomes speak to the need for nuanced identification of home environment factors that are beneficial to particular math competencies. The findings also suggest cultural variations in the mechanisms that support children's mathematical development, highlighting the merits of investigating this topic in non-Western contexts.

Children's beliefs in invisible causal agents-Both religious and scientific.

Against the proposal that children have a natural disposition for supernatural or religious beliefs, we review the decades-old evidence showing that children typically invoke naturalistic causes-even in the face of unusual outcomes. Instead, we propose that children's tendency to endorse supernatural agents reflects their capacity for cultural learning rather than an inherent inclination to believe in divine powers. We support this argument by reviewing the findings that religious exposure in childhood, not individual cognitive or personality factors, is the major determinant of religiosity in adulthood. We highlight the role of cultural learning in children's endorsement of invisible divine agents by drawing on cross-cultural evidence that children are equally receptive to claims regarding the existence of invisible natural agents. We end by introducing a hypothesis to explain how children come to endorse religious beliefs despite their bias toward naturalistic explanation.

Do Bad People Deserve Empathy? Selective Empathy Based on Targets' Moral Characteristics.

The relation between empathy and morality is a widely discussed topic. However, previous discussions mainly focused on whether and how empathy influences moral cognition and moral behaviors, with limited attention to the reverse influence of morality on empathy. This review summarized how morality influences empathy by drawing together a number of hitherto scattered studies illustrating the influence of targets' moral characteristics on empathy. To explain why empathy is morally selective, we discuss its ultimate cause, to increase survival rates, and five proximate causes based on similarity, affective bonds, the appraisal of deservingness, dehumanization, and potential group membership. To explain how empathy becomes morally selective, we consider three different pathways (automatic, regulative, and mixed) based on previous findings. Finally, we discuss future directions, including the reverse influence of selective empathy on moral cognition, the moral selectivity of positive empathy, and the role of selective empathy in selective helping and third-party punishment.

Does first-hand evidence undermine young children's initial trust in positive gossip? Evidence from 5- to 6-year-old children.

What happens when children have formed an impression of a peer based on prior gossip, but later learn from direct observation that the gossip is untrue? We interviewed seventy 5- and 6-year-old children in Zhejiang, China. They first heard conflicting positive and negative gossip about an absent third party, and subsequently learned which piece of gossip was true. Initially, both 5- and 6-year-old children tended to endorse the positive rather than the negative gossip. However, when they learned about the inaccuracy of the positive gossip based on their own direct observation, 6-year-old children subsequently doubted it, whereas 5-year-old children showed no such shift. Taken together, the results show that when children decide what gossip to believe, they are initially swayed by its valence but with age they increasingly weigh gossip in relation to their own direct observation.

Expressions of uncertainty in invisible scientific and religious phenomena during naturalistic conversation.

Across cultures, studies report more confidence in the existence of unobservable scientific phenomena, such as germs, as compared to unobservable religious phenomena, such as angels. We investigated a potential cultural mechanism for the transmission of confidence in the existence of invisible entities. Specifically, we asked whether parents in societies with markedly different religious profiles-Iran and China-signal differential confidence across the domains of science and religion during unmoderated conversations with their children (N = 120 parent-child dyads in total; 5- to 11-year-olds). The results revealed that parents used fewer lexical cues to uncertainty when discussing scientific phenomena, as compared to religious phenomena. Unsurprisingly, this cross-domain distinction was observed among majority belief, secular parents in China (Study 2). More importantly, however, the same pattern was observed among parents in Iran, a highly religious society (Study 1), as well as among minority belief, religious parents in China (Study 2). Thus, adults in markedly different belief communities spontaneously express less confidence in religious, as compared to scientific, invisible entities in naturalistic conversation. These findings contribute to theories on the role of culture and testimony in the development of beliefs about unobservable phenomena.

Being nice by choice: The effect of counterfactual reasoning on children's social evaluations.

The ability to engage in counterfactual thinking (reason about what else could have happened) is critical to learning, agency, and social evaluation. However, not much is known about how individual differences in counterfactual reasoning may play a role in children's social evaluations. In the current study, we investigate how prompting children to engage in counterfactual thinking about positive moral actions impacts children's social evaluations. Eighty-seven 4-8-year-olds were introduced to a character who engaged in a positive moral action (shared a sticker with a friend) and asked about what else the character could have done with the sticker (counterfactual simulation). Children were asked to generate either a high number of counterfactuals (five alternative actions) or a low number of counterfactuals (one alternative action). Children were then asked a series of social evaluation questions contrasting that character with one who did not have a choice and had no alternatives (was told to give away the sticker to his friend). Results show that children who generated selfish counterfactuals were more likely to positively evaluate the character with choice than children who did not generate selfish counterfactuals, suggesting that generating counterfactuals most distant from the chosen action (prosociality) leads children to view prosocial actions more positively. We also found age-related changes: as children got older, regardless of the type of counterfactuals generated, they were more likely to evaluate the character with choice more positively. These results highlight the importance of counterfactual reasoning in the development of moral evaluations. RESEARCH HIGHLIGHTS: Older children were more likely to endorse agents who choose to share over those who do not have a choice. Children who were prompted to generate more counterfactuals were more likely to allocate resources to characters with choice. Children who generated selfish counterfactuals more positively evaluated agents with choice. Comparable to theories suggesting children punish willful transgressors more than accidental transgressors, we propose children also consider free will when making positive moral evaluations.

Beyond enjoyment: Young children consider the normative goodness of activity engagement when attributing happiness.

Individuals are typically happy when engaging in enjoyable activities. But many enjoyable activities could be harmful when engaged in to excess. Do children consider the normative goodness of activity engagement levels when attributing happiness? To examine this question, we presented children with enjoyable activities that are often harmless in moderation but harmful in excess. When told that engaging in their favorite activities at their preferred amount was either normatively good (i.e., harmless and permitted) or normatively bad (i.e., harmful and forbidden), 10- and 11-year-old and 7- and 8-year-old children (Study 1) and even 5-year-old children (Studies 2 and 3 with simplified methods) attributed less happiness when the engagement level was normatively bad than when it was normatively good both to themselves and to another child. Young children also perceived normatively bad engagement as less interesting and pleasurable (Study 3). The findings suggest that children consider the normative goodness of activity engagement (rather than enjoyment alone) when attributing happiness, illuminating how children understand happiness.

Miraculous, magical, or mundane? The development of beliefs about stories with divine, magical, or realistic causation.

Children's naïve theories about causal regularities enable them to differentiate factual narratives describing real events and characters from fictional narratives describing made-up events and characters (Corriveau, Kim, Schwalen, & Harris, Cognition 113 (2): 213-225, 2009). But what happens when children are consistently presented with accounts of miraculous and causally impossible events as real occurrences? Previous research has shown that preschoolers with consistent exposure to religious teaching tend to systematically judge characters involved in fantastical or religious events as real (Corriveau et al., Cognitive Science, 39 (2), 353-382, 2015; Davoodi et al., Developmental Psychology, 52 (2), 221, 2016). In the current study, we extended this line of work by asking about the scope of the impact of religious exposure on children's reality judgments. Specifically, we asked whether this effect is  domain-general or domain-specific. We tested children in Iran, where regular exposure to uniform religious beliefs might influence children's reasoning about possibility in non-religious domains, in addition to the domain of religion. Children with no or minimal schooling (5- to 6-year-olds) and older elementary school students (9- to 10-year-olds) judged the reality status of different kinds of stories, notably realistic, unusual (but nonetheless realistic), religious, and magical stories. We found that while younger children were not systematic in their judgments, older children often judged religious stories as real but rarely judged magical stories as real. This developmental pattern suggests that the impact of religious exposure on children's reality judgments does not extend beyond their reasoning about divine intervention. Children's justifications for their reality judgments provided further support for this domain-specific influence of religious teaching.

Older children verify adult claims because they are skeptical of those claims.

We investigated children's information seeking in response to a surprising claim (Study 1, N = 109, 54 Female, Range = 4.02-6.94 years, 49% White, 21% Mixed Ethnicity, 19% Southeast Asian, September 2019-March 2020; Study 2, N = 154, 74 Female, Range = 4.09-7.99, 50% White, 20% Mixed Ethnicity, 17% Southeast Asian, September 2020-December 2020). Relative to younger children, older children more often expressed skepticism about the adult's surprising claims (1-year increase, OR = 2.70) and more often suggested exploration strategies appropriate for testing the specific claim they heard (1-year increase, OR = 1.42). Controlling for age, recommending more targeted exploration strategies was associated with a greater likelihood of expressing skepticism about the adult's claim.

Hearing about a story character's negative emotional reaction to having been dishonest causes young children to cheat less.

There is extensive research on the development of cheating in early childhood but research on how to reduce it is rare. The present preregistered study examined whether telling young children about a story character's emotional reactions towards cheating could significantly reduce their tendency to cheat (N = 400; 199 boys; Age: 3-6 years). Results showed that telling older kindergarten children about the story character's negative emotional reaction towards rule violation significantly reduced cheating, but telling them about the positive emotional reaction towards rule adherence did not. These results show that children as young as age 5 are able to use information about another child's emotional reaction to guide their own moral behavior. In particular, highlighting another child's negative emotional reaction towards a moral transgression may be an effective way to reduce cheating in early childhood. This finding, along with earlier cheating reduction findings, suggests that although cheating is common in early childhood, simple methods can reduce its occurrence.

The development of the imagination and imaginary worlds.

Evidence from developmental psychology on children's imagination is currently too limited to support Dubourg and Baumard's proposal and, in several respects, it is inconsistent with their proposal. Although children have impressive imaginative powers, we highlight the complexity of the developmental trajectory as well as the close connections between children's imagination and reality.

Young children share imagined possibilities: evidence for an early-emerging human competence.

Children's ability to reason about junctures leading to two different destinations emerges slowly, with convergent evidence for a conceptual watershed at approximately 4 years. Young children and great apes misrepresent such junctures, planning for only one expected outcome. However, singular possibilities, as opposed to two mutually exclusive possibilities, are readily imagined, shared and acted upon by 2- and 3-year-olds. Analysis of three domains supports this claim. First, 2- and 3-year-olds respond appropriately to pretend spatial displacements enacted for them by a play partner. Second, they not only respond accurately to claims regarding an alleged but unwitnessed spatial displacement, they also ask their interlocutors about the possible whereabouts of missing objects and absent persons. Third, in ordinary conversation, they appropriately mark some of their assertions as possibilities rather than actualities. In summary, although the ability to reason about mutually inconsistent possibilities develops slowly in the preschool years, the ability to imagine and share information about possibilities is evident among 2- and 3-year-olds. Nothing comparable has been observed in great apes. Young children's ability to entertain shared possibilities diverges from that of non-human primates well before any potential watershed at 4 years with respect to the understanding of mutually exclusive possibilities. This article is part of the theme issue 'Thinking about possibilities: mechanisms, ontogeny, functions and phylogeny'.

A counting intervention promotes fair sharing in preschoolers.

Recent work has probed the developmental mechanisms that promote fair sharing. This work investigated 2.5- to 5.5-year-olds' (N = 316; 52% female; 79% White; data collected 2016-2018) sharing behavior in relation to three cognitive correlates: number knowledge, working memory, and cognitive control. In contrast to working memory and cognitive control, number knowledge was uniquely associated with fair sharing even after controlling for the other correlates and for age. Results also showed a causal effect: After a 5-min counting intervention (vs. a control), children improved their fair sharing behavior from pre-test to post-test. Findings are discussed in light of how social, cognitive, and motivational factors impact sharing behavior.

What could have been done? Counterfactual alternatives to negative outcomes generated by religious and secular children.

Recent research has shown that a religious upbringing renders children receptive to ordinarily impossible outcomes, but the underlying mechanism for this effect remains unclear. Exposure to religious teachings might alter children's basic understanding of causality. Alternatively, religious exposure might only affect children's religious cognition, not their causal judgments more generally. To test between these possibilities, 6- to 11-year-old children attending either secular (n = 49, 51% female, primarily White and middle-class) or parochial schools (n = 42, 48% female, primarily White and middle-class) heard stories in which characters experienced negative outcomes and indicated how those characters could have prevented them. Both groups of children spontaneously invoked interventions consistent with natural causal laws. Similarly, when judging the plausibility of several counterfactual interventions, participants endorsed the intervention consistent with natural laws at high levels, irrespective of schooling. However, children's endorsement of supernatural interventions inconsistent with these laws revealed both group similarities and differences. Although both groups of children judged divine intervention (i.e., via prayer) as more plausible than mental (i.e., via wishing) and magical (i.e., via magical powers) interventions, children receiving religious (vs. secular) schooling were more likely to do so. Moreover, although children with a secular upbringing overwhelmingly chose naturalistic interventions as the most effective, children with a religious upbringing chose divine as well as naturalistic intervention. These results indicate that religious teaching does not alter children's basic understanding of causality but rather adds divine intervention to their repertoire of possible causal factors.

Infants actively seek and transmit knowledge via communication.

Supporting the central claim that knowledge representation is more basic than belief representation, we focus on the emerging evidence for preverbal infants' active and selective communication based on their representation of both knowledge and ignorance. We highlight infants' ontogenetically early deliberate information seeking and information transmission in the context of active social learning, arguing that these capacities are unique to humans.

Children's Ideas About What Can Really Happen: The Impact of Age and Religious Background.

Five- to 11-year-old U.S. children, from either a religious or secular background, judged whether story events could really happen. There were four different types of stories: magical stories violating ordinary causal regularities; religious stories also violating ordinary causal regularities but via a divine agent; unusual stories not violating ordinary causal regularities but with an improbable event; and realistic stories not violating ordinary causal regularities and with no improbable event. Overall, children were less likely to judge that religious and magical stories could really happen than unusual and realistic stories although religious children were more likely than secular children to judge that religious stories could really happen. Irrespective of background, children frequently invoked causal regularities in justifying their judgments. Thus, in justifying their conclusion that a story could really happen, children often invoked a causal regularity, whereas in justifying their conclusion that a story could not really happen, they often pointed to the violation of causal regularity. Overall, the findings show that children appraise the likelihood of story events actually happening in light of their beliefs about causal regularities. A religious upbringing does not impact the frequency with which children invoke causal regularities in judging what can happen, even if it does impact the type of causal factors that children endorse.

Preschool Children Rarely Seek Empirical Data That Could Help Them Complete a Task When Observation and Testimony Conflict.

Children (N = 278, 34-71 months, 54% girls) were told which of two figurines turned on a music box and also observed empirical evidence either confirming or conflicting with that testimony. Children were then asked to sort novel figurines according to whether they could make the music box work or not. To see whether children would explore which figurine turned on the music box, especially when the observed and testimonial evidence conflicted, children were given access to the music box during their sorting. However, children rarely explored. Indeed, they struggled to disregard the misleading testimony both when sorting the figurines and when asked about a future attempt. In contrast, children who explored the effectiveness of the figurines dismissed the misleading testimony.

Early Constraints on the Imagination: The Realism of Young Children.

The imagination of young children has notable constraints. The outcomes and possibilities that they imagine rarely deviate from the everyday regularities they have observed and remembered. Their reality-based imagination is evident in a variety of contexts: early pretend play, envisioning the future, judgments about what is possible, the instructive role of thought experiments, tool making, and figurative drawing. Overall, the evidence shows that children's imagination helps them to anticipate reality and its close alternatives. This perspective invites future research on the scope of children's thinking about counterfactual possibilities, their ability to make discoveries about reality on the basis of thought experiments, and the ways in which cultural input can expand the scope of the possibilities that they entertain.
