Learning from others allows young children to acquire vast amounts of information quickly, but doing so effectively also requires epistemic vigilance. Although preschool-age children have some capacity to engage in such processes, they often have trouble resisting information from misleading informants. The present research takes a novel

People are sometimes tempted to lie for their own benefit if it would not harm others. For adults, dishonesty is the default response in these circumstances. The developmental origins of this phenomenon were investigated between 2019 and 2021 among 6- to 11-year-old Han Chinese children from China (N = 548, 49% female). Children had an opportunity to win prizes in a behavioral economics game (Experiment 1) or a temptation resistance game adapted from developmental psychology (Experiment 2). In each experiment, the youngest children showed a default tendency of honesty and there was an overall age-related shift toward a default tendency of dishonesty. These findings provide direct evidence of developmental change in the automatic and controlled processes that underlie moral behavior.

Numerous studies suggest that speakers of some tone languages show advantages in musical pitch processing compared to non-tone language speakers. A recent study in adults (Jasmin et al., 2021) suggests that in addition to heightened pitch sensitivity, tone language speakers weight pitch information more strongly than other auditory cues (amplitude, duration) in both linguistic and nonlinguistic settings compared to non-tone language speakers. The current study asks whether pitch upweighting is evident in early childhood. To test this, two groups of 3- to 5-year-old children—tone-language speakers (n = 48), a group previously shown to have a perceptual advantage in musical pitch tasks (Creel et al., 2018), and non-tone-language speakers (n = 48)—took part in a musical “word learning” task. Children associated two cartoon characters with two brief musical phrases differing in both musical instrument and contour. If tone language speakers weight pitch more strongly, cue conflict trials should show stronger pitch responding than for non-tone speakers. In contrast to both adult speakers’ stronger pitch weighting and child and adult pitch perception advantages, tone-language-speaking children did not show greater weighting of pitch information than non-tone-language speaking children. This suggests a slow developmental course for pitch reweighting, contrasting with apparent early emergence of pitch sensitivity.

To make accurate causal inferences about social-group inequalities, people must consider structural causes. Structural causes are a distinct type of extrinsic cause—they are stable, interconnected societal forces that systematically advantage some social groups and disadvantage others. We propose a new cognitive framework to specify how people attribute inequality to structural causes. This framework is rooted in counterfactual theories of causal judgment and suggests that people will recognize structural factors as causal when they are perceived as “difference-making” for inequality above and beyond any intrinsic causes. Building on this foundation, our framework makes the following contributions. First, we propose specific types of evidence that support difference-making inferences about structural factors: within-group change (i.e., observing that disadvantaged groups’ outcomes improve under better societal conditions) and well-matched between-group comparisons (i.e., observing that advantaged group members, who have similar baseline traits to the disadvantaged group, experience more favorable societal conditions and life outcomes). Second, we consider contextual, cognitive, and motivational barriers that may complicate the availability and acceptance of this evidence. We conclude by exploring how the framework might be applied in future research examining people’s causal inferences about inequality.

This research examined the effects of overhearing an adult praise an unseen child for not needing to work hard on an academic task. Five-year-old Han Chinese children (total N = 270 across three studies; 135 boys, collected 2020-2021) who heard this low effort praise tended to devalue effort relative to a baseline condition in which the overheard conversation lacked evaluative content. In Study 3, low effort praise increased children's endorsement of essentialist beliefs about ability and their interest in becoming the kind of person who does not need to work hard to succeed. The findings show that overhearing evaluative comments about other people, a pervasive feature of daily life, can have a systematic effect on young children's beliefs about achievement.

This research examined the effectiveness of using norms to promote honesty. Participants were Han Chinese children (N = 568, 50.4% male, 3.24 to 6.00 years, collected 2020-2022). Relative to children in a control condition, children in Study 1 were more likely to confess to having cheated in a game after being presented with a descriptive norm indicating that confessions are typical, or an injunctive norm indicating that most other children approve of confessing. Study 2 showed that this finding was not due to a methodological artifact, and Study 3 replicated the effect in a context in which the norm information was conveyed by someone other than the experimenter. The findings suggest that messages about social norms can influence children's honesty.

Individuation training that helps humans see multiple other-race targets as distinct rather than as interchangeable can reduce children’s implicit racial bias in the form of more negative other-race associations than own-race associations. However, little is known about which aspects of these interventions are critical for their effectiveness. The present research examines whether children need to learn to differentiate among multiple other-race individuals for these interventions to reduce their level of implicit racial bias, or whether differentiating a single other-race individual is sufficient. We addressed this question among 4-to-6-year-old Chinese children (N = 66, 31 girls) who engaged in coordinated movement with Black instructors for 2 min. There were two between-subject conditions: in a differentiation condition, there were four different Black instructors, and children had to learn to tell them apart, and in a no-differentiation condition, there was only one Black instructor. Implicit bias was measured using the IRBT, an implicit association test that was developed based on the IAT but is appropriate for young children. We found a reduction in implicit bias against Black people after this interaction in the differentiation condition, but not in the no-differentiation condition. These findings suggest that learning to differentiate among multiple other-race individuals plays a critical role in reducing children’s implicit racial bias.

Much of what people do is motivated by a concern with social evaluation. We argue that the process of figuring out what others value and making effective use of this information presents significant cognitive challenges. These challenges include reasoning about the relevance of different forms of information and making inferences about the mental lives of others. They also include modifying one’s behavior in light of whatever personal qualities appear to be valued in an effort to appeal to different audiences. We argue that the foundations of many of the important skills needed to meet these challenges are already in place early during childhood, but that the challenges themselves persist well into adulthood.

Age-related differences in explicit and implicit racial biases in Black Cameroonians (N = 187, 94 females) were investigated using a cross-sectional design. Participants ranged in age from 3 to 30 years, and were from middle-to-high income families in Yaoundé, Cameroon. Biases were assessed by comparing attitudes toward Blacks with those toward Whites and Chinese. Implicit pro-Black/anti-other-race (White and Chinese) biases were present at age 4, in contrast to anti-Black/pro-other-race biases, which were observed among 9- to 30-year-olds. In addition, explicit pro-Black/anti-other-race biases that were present at age 4 were no longer evident by age 7. These findings provide a detailed picture of age-related differences in racial biases in an understudied part of the world that can inform theories regarding the development of racial biases, as well as efforts to reduce such biases.

How to distribute resources in a fair way is a fundamental source of conflict in human societies. A central dilemma that people begin to grapple with during childhood is the extent to which individuals should be rewarded based on merit at the expense of equality. The current study examined children's reasoning about this dilemma by testing whether they are sensitive to information about the motives of highly productive people when determining whether they should receive extra compensation. Across two studies, children (6- to 11-year-olds, total N = 143) judged high performers to be less deserving of extra resources when they were motivated by profit rather than being intrinsically motivated, and this pattern was more pronounced among the older children. The findings demonstrate that, with age, children increasingly consider motives when deciding whether productivity should be rewarded and that the tendency of adults to view profit motives as problematic has origins during childhood.

There has been extensive research on the causes of academic cheating, but little is known about its consequences. The current research sought to fill this gap in the literature by examining how cheating by middle school children (total N = 198) affects their learning outcomes. In a naturalistic paradigm, children scored a math test they had taken previously, which gave them an opportunity to cheat by falsely scoring incorrect answers to be correct. Results from this phase showed that 54 % of the children cheated on at least one question. One week later, the children took the same test again, but this time without being given an opportunity to cheat. Among children who cheated, items they had answered incorrectly on the first round showed significantly less improvement on the second round if they had dishonestly scored them as correct rather than honestly scoring them as incorrect. This finding provides the first experimental evidence that academic cheating can interfere with children's learning.

The present dataset was reported in a paper entitled "Effects of test difficulty messaging on academic cheating among middle school children" [1]. It reports the findings of an experimental study that used a naturalistic math test-taking paradigm to assess children's academic cheating behavior under different test difficulty messaging conditions. The participants were Grade 8 middle school children (

The current highly polarized U.S. political culture impedes people’s ability to live and work together effectively. Here we examine one factor that may play a role: selective empathy based on shared political ideology. Across seven studies ( N = 3,476), participants read about a hypothetical politician and his political ideology, trustworthiness, or both. Participants reported their empathy for the politician after learning he was fined (Studies 1–6) or injured (Study 7). When trustworthiness alone was manipulated, liberals and conservatives expressed similar levels of empathy, with greater empathy for the more trustworthy politician. However, when the politician’s ideology alone was manipulated, participants reported greater empathy for the politician who shared their ideology. When trustworthiness and ideology were manipulated, selective empathy was observed when the politician was trustworthy. Participant ideology alone had little effect on empathy. The results suggest that empathy is sensitive to both trustworthiness and ideological match, but not ideology itself.

In this preregistered field study, we examined preschool children’s selective trust in a real-life situation. We investigated whether 3- to 6-year-old children (total N = 240) could be lured to a new location within their school grounds by an unfamiliar adult confederate. In a between-subjects manipulation, the confederate established either a high or a low level of personal credibility by providing information that the child knew to be either true or false. In Experiment 1, in which the confederate was female, children showed sensitivity to informational accuracy by being less willing to leave with an uninformed confederate, and this effect increased with age. In Experiment 2, in which the confederate was male, children were reluctant to leave regardless of informational accuracy. These findings point to real-world implications of epistemic-trust research and provide the first evidence regarding the early development of selective trust in a high-stakes naturalistic context.

The results of multiple behavioral investigations indicate that children can develop spontaneous trait inferences (STIs) starting from when they are 8-9 years of age. However, little is known about the neural correlates of STIs when they first develop. In the present study, we measured event-related potentials (ERPs) and event-related spectral perturbation (ERSP) using an N400 paradigm. Seventeen 9-year-old Chinese children were first instructed to remember facial photos and paired trait-implying behaviors. Subsequently, they performed a lexical decision task in which faces were used to prime the inferred traits or their antonyms. Compared to the inferred traits, the antonyms exhibited a stronger amplitude on both N400 (370-500 ms) and negative slow wave (NSW; 550-800 ms). However, only N400 showed a right hemispheric dominance of STIs. In addition, ERSP results revealed stronger lower alpha band (7-10 Hz) activity for antonyms than inferred traits over the right parieto-occipital area from 420 ms to 800 ms. These findings, coupled with the electroencephalography (EEG) source localization (standardized low-resolution electromagnetic tomography [sLORETA]), provide evidence for a "monitoring-control" two-stage neural network.

This research presents a nudge-based approach to promoting honest behavior. Specifically, we introduce the moral barrier hypothesis, which posits that moral violations can be inhibited by the introduction of spatial boundaries, including ones that do not physically impede the act of transgressing. We found that, as compared to a no barrier condition, children cheated significantly less often when a barrier was strategically placed to divide the space where children were seated from a place that was associated with cheating. This effect was seen both when the barrier took a physical form and when it was purely symbolic. However, the mere presence of a barrier did not reduce cheating: if it failed to separate children from a space that was associated with cheating, children cheated as much as when there was no barrier at all. Taken together, these findings support the moral barrier hypothesis and show that even seemingly unremarkable features of children’s environments can nudge them to act honestly.

Children generally favor individuals in their own group over others, but it is unclear which dimensions of the out-group affect this bias. This issue was investigated among 7- to 8-year-old and 11- to 12-year-old Iranian children (N = 71). Participants evaluated in-group members and three different out-groups: Iranian children from another school, Arab children, and children from the United States. Children's evaluations closely aligned with the perceived social status of the groups, with Americans viewed as positively as in-group members and Arabs viewed negatively. These patterns were evident on measures of affiliation, trust, and loyalty. These findings, which provide some of the first insights into the social cognition of Iranian children, point to the role of social status in the formation of intergroup attitudes.

Previous studies have found that using software to pitch shift people's voices can boost their perceived attractiveness to opposite-sex adults: men prefer women's voices when pitch-shifted up, and women prefer men's voices when pitch-shifted down. In this study, we sought to determine whether speakers could affect their perceived vocal attractiveness by voluntarily shifting their own voices to reach specific target pitches (+20 Hz or −20 Hz, a pitch increment that is based on prior research). Two sets of Chinese college students participated in the research: 115 who served as speakers whose voices were recorded, and 167 who served as raters who evaluated the speakers' voices. We found that when female speakers increased their pitch they were judged as more attractive to both opposite-sex and same-sex raters. An additional unexpected finding was that male speakers tended to rate other males who shifted their voice up in pitch as more attractive. These findings suggest that voluntary pitch shifts can affect attractiveness, but that they do not fully match the patterns observed when pitch shifting is done digitally.

Cheating is a common human behavior but few studies have examined its emergence during early childhood. In three preregistered studies, a challenging math test was administered to 5- to 6-year-old children (total N = 500; 255 girls). An answer key was present as children completed the test, but they were instructed to not peek at it. In Study 1, many children cheated, but manipulations that reduced the answer key's accessibility in terms of proximity and visibility led to less cheating. Two follow-up studies showed that the answer key's visibility played a more significant role than its proximity. These findings suggest that subtle and seemingly insignificant alterations of the physical environment can effectively nudge young children away from acting dishonestly.

Interpersonal trust plays a crucial role in the formation and maintenance of social relationships. The present cross-sectional and longitudinal research examines the development of interpersonal trust judgments with reference to (1) the trustee’s reputation for trustworthiness, and (2) the nature of the trustor’s relationship closeness with the trustee. There were 194 7- to 13-year-olds who participated in the first wave of the study, and 107 of those individuals also participated in two subsequent waves across a 2-year period. Both cross-sectional and longitudinal results showed that with age, reputation for trustworthiness becomes less important and relationship closeness become more important. We also found that relationship closeness played a greater role in interpersonal trust evaluations for girls than for boys. These findings indicate that the way children make trust evaluations becomes increasingly relationship-specific over time and is more relationship-specific for girls than for boys.

The goal of the present research was to assess whether children's first interaction with a single outgroup member can significantly impact their general attitudes toward the outgroup as a whole. In two preregistered studies, 5- to 6-year-old Chinese children (total N = 147) encountered a Black adult from another country for the very first time, and they played a game together. General attitudes toward the outgroup were assessed using both implicit and explicit measures. In both studies, the interaction resulted in less negative explicit attitudes toward Black people, but more negative implicit attitudes. The results demonstrate for the first time that one encounter with a single outgroup member can impact children's general attitudes toward that group, and that it can have differential effects on implicit and explicit attitudes.

A fundamental part of understanding structural inequality is recognizing that constrained choices, particularly those that align with societal stereotypes, are poor indicators of a person's desires. This study examined whether children (N = 246 U.S. children, 53% female; 61% White, 24% Latinx; 5-10 years) acknowledge constraints in this way when reasoning about gender-stereotypical choices, relative to gender-neutral and gender-counterstereotypical choices. Results indicated that children more frequently inferred preferences regardless of whether the actor was constrained when reasoning about gender-stereotypical choices, as compared to gender-neutral or gender-counterstereotypical choices. We also found evidence of an age-related increase in the general tendency to acknowledge constraints. We discuss the broader implications of these results for children's understanding of constraints within society.

Academic cheating is a serious worldwide problem that begins during childhood. However, to date there has been little research on academic cheating with children before high school age. The current study used a naturalistic experimental paradigm to evaluate the possibility that systematically manipulating messages about the difficulty of a test can affect whether middle school children (N = 201) would cheat by reporting a falsely inflated test score. We found that test difficulty messaging significantly affected children's cheating behavior. Specifically, telling children that a test was either easy or hard produced higher rates of cheating than telling them that the difficulty level was on par with their current skills. In addition, among the children who chose to cheat, telling them that the test was easy led to a greater degree of cheating. These findings are consistent with theories of academic cheating that point to the importance of approach and avoidance motives in achievement motivation. The findings also suggest that simple messaging can have a significant impact on children's moral behavior and that seemingly innocuous messages such as describing the difficulty of a test can influence children's decisions about whether and how much to cheat.

Children live in a world where disagreement is commonplace. Although disagreement can sometimes be explained by differences in people's reliability, disagreement may also indicate that the referent elicits multiple perspectives. The present studies (total N = 129, 5- to 12-year-old ethnically diverse U.S. children, 42% girls) examined children's ability to resolve disagreement among two individuals by identifying referents that integrated the perspectives, and considered the extent to which any age-related change could be explained by epistemological understanding (i.e., acknowledging that two perspectives can be right). Children's age was positively correlated with their ability to integrate perspectives, and children performed at above-chance levels by approximately 10 years of age. Age differences in integrating perspectives were partially accounted for by epistemological understanding.
