This study examined how adolescents make meaning of racist jokes and their impact on daily well-being using a sequential mixed-methods research design with interview (N = 20; 60% girls, 5% gender-nonconforming; 45% Asian American, 40% Latina/o/x, 10% Black, 5% biracial/multiethnic) and daily diary data (N = 168; 54% girls; 57% Latina/o/x, 21% biracial/multiethnic, 10% Asian American, 9% White, 4% Black). Qualitative results revealed that racist jokes were common, distinct from other overt forms of discrimination, and perceived as harmless when perpetrated by friends. Quantitatively, approximately half of adolescents reported hearing at least one racist joke during the study period, and racist jokes by friends were associated with higher daily angry, anxious, and depressed moods and stress. Racist jokes by known others and strangers were also significantly associated with poorer well-being, although less consistently. Findings highlight the hidden harmful effects of racist jokes on adolescents’ daily mood and stress.

This study addressed whether combining tinkering with digital storytelling (i.e., narrating and reflecting about experiences to an imagined audience) can engender engineering learning opportunities. Eighty-four families with 5- to 10-year-old (M = 7.69) children (48% female children; 57% White, 11% Asian, 6% Black) watched a video introducing a tinkering activity and were randomly assigned either to a digital storytelling condition or a no digital storytelling condition during tinkering. After tinkering, families reflected on their tinkering experience and were randomly assigned to either engage in digital storytelling or not. Children in the digital storytelling condition during tinkering spoke most to an imagined audience during tinkering, talked most about engineering at reflection, and remembered the most information about the experience weeks later.

Although children exhibit curiosity regarding science, questions remain regarding how children evaluate others' curiosity and whether evaluations differ across domains that prioritize faith (e.g., religion) versus those that value questioning (e.g., science). In Study 1 (n = 115 5- to 8-year-olds; 49% female; 66% White), children evaluated actors who were curious, ignorant and non-curious, or knowledgeable about religion or science; curiosity elicited relatively favorable moral evaluations (ds > .40). Study 2 (n = 62 7- to 8-year-olds; 48% female; 63% White) found that these evaluations generalized to behaviors, as children acted more pro-socially and less punitively toward curious, versus not curious, individuals ($��{\eta }_p^2�$ = .37). These findings (data collected 2020–2022) demonstrate children's positive moral evaluations of curiosity and contribute to debates regarding overlap between scientific and religious cognition.

This study tested intuitions about ownership in children of Dani people, an indigenous Papuan society (N = 79, M_age = 7, 49.4% females). The results show that similar to studies with children from Western societies, children infer ownership from (1) control of permission, (2) ownership of the territory the object is located in, and (3) manmade versus natural origins of the object. By contrast, they did not (4) infer ownership from the first observed possession of an object. Additionally, Papuan children showed (5) an absolute first possession heuristic, whereby they assigned ownership to a person who achieved a goal, in contrast to a person who was first to pursue this goal but failed to be the first to claim it.

Memory enables generalization to new situations, and memory specificity that preserves individual episodes. This study investigated generalization, memory specificity, and their overnight fate in 141 4- to 8-year-olds (computerized memory game; 71 females, tested 2020–2021 in Germany). The results replicated age effects in generalization and memory specificity, and a contingency of generalization on object conceptual properties and interobject semantic proximity. Age effects were stronger in generalization than in memory specificity, and generalization was more closely linked to the explicit regularity knowledge in older than in younger children. After an overnight delay, older children retained more generalized and specific memories and showed greater gains but only in generalization. These findings reveal distinct age differences in generalization and memory specificity across childhood.

Independent decision making requires forming stable estimates of one's preferences. We assessed whether adolescents learn about their preferences through choice deliberation and whether depressive symptoms disrupt this process. Adolescents aged 11–18 (N = 214; participated 2021–22; Female: 53.9%; White/Black/Asian/Mixed/Arab or Latin American: 26/21/19/9/8%) rated multiple activities, chose between pairs of activities and re-rated those activities. As expected, overall, participants uprated chosen and downrated unchosen activities (dz = .20). This value refinement through choice was not evident in younger participants but emerged across adolescence. Contrary to our predictions, depressive symptoms were associated with greater value refinement. Despite this, more depressed adolescents reported lower value certainty and choice confidence. The cognitive processes through which choice deliberation shapes preference develop over adolescence, and are disrupted in depression.

The family and classroom are important contexts that can contribute to the socialization of ethnic prejudice. However, less is known about their unique, relative, and synergic contributions in influencing youth's affective and cognitive prejudice. The current longitudinal study examined these processes and possible moderators among 688 Italian youth (49.13% girls; M_age = 15.61 years), their parents (n_mothers = 603, n_fathers = 471; M_age = 49.51 years), and classmates between January/February 2022 and January/February 2023. Cross-lagged panel models highlighted that parents and classmates exert unique and relative influences on different dimensions of adolescents' prejudice. Additionally, different interaction effects also emerged for affective (i.e., adverse compensatory effect) and cognitive (i.e., amplifying effect) prejudice. Thus, adolescents draw from the multiple contexts of development to orient themselves in the social world.

This study examined how socioeconomic status (SES) influences on decision-making processing. The roles of anticipatory/outcome-related cardiac activity and awareness of task contingencies were also assessed. One hundred twelve children (M_age = 5.83, SD_age = 0.32; 52.7% female, 51.8% low-SES; data collected October–December 2018 and April–December 2019) performed the Children's Gambling Task, while heart rate activity was recorded. Awareness of gain/loss contingencies was assessed after completing the task. Distinct decision-making strategies emerged among low and middle/high-SES children. Despite similar awareness levels between SES groups, future-oriented decision-making was linked solely to the middle/high-SES group. Somatic markers did not manifest unequivocally. However, contrasting cardiac patterns were evident concerning feedback processing and the association between anticipatory activity and awareness (low: acceleration vs. middle/high: deceleration). Results are interpreted from an evolutionary-developmental perspective.

This meta-analysis linked relative and absolute parental differential treatment (PDT) with internalizing and externalizing behavior of children and adolescents. Multilevel meta-analysis data represented 26,451 participants based on 2890 effect sizes coming from 88 sources, nested within 43 samples. Participants were between 3.18 and 18.99 years of age (M_age = 12.64, SD = 3.89; 51.31% female; 82.23% White; 54.68% from the United States). Less-favored treatment (relative PDT) was linked to more internalizing and externalizing behavior. Additionally, greater differences in parenting between siblings (absolute PDT) were linked to more internalizing and externalizing behavior. Some links were moderated by other factors. For example, some effects were stronger when PDT was reported by children, and others, when siblings were closer in age.

This study investigated associations of the Incredible Years (IY) parenting program with children's DNA methylation. Participants were 289 Dutch children aged 3–9 years (75% European ancestry, 48% female) with above-average conduct problems. Saliva was collected 2.5 years after families were randomized to IY or care as usual (CAU). Using an intention-to-treat approach, confirmatory multiple-regression analyses revealed no significant differences between the IY and CAU groups in children's methylation levels at the NR3C1 and FKBP5 genes. However, exploratory epigenome-wide analyses revealed nine differentially methylated regions between groups, coinciding with SLAMF1, MITF, FAM200B, PSD3, SNX31, and CELSR1. The study provides preliminary evidence for associations of IY with children's salivary methylation levels and highlights the need for further research into biological outcomes of parenting programs.
