Informed by the biological sensitivity to the context (BSC) theory, this multimethod, longitudinal study sought to examine how family context may be associated with the development of child sensory processing sensitivity (SPS) over a year. Participants were 235 young children (Mage = 2.97 at the first measurement occasion, 55.3% were girls) and their parents (median annual household income $55,000 to 74,999), who were followed for two annual measurement occasions. These children consisted of 56.2% White, 21.3% African American, and 16.2% mixed race. Child SPS was measured via behavioral observation within multiple laboratory tasks at both waves and exhibited moderate stability over time. A curvilinear association between environmental harshness and the change in child SPS emerged, which proved consistent with the U-shaped pattern hypothesized by the BSC theory. Children remain at similar levels of SPS over the year under low and high levels of environmental harshness but exhibited decreases in SPS under moderate levels of environmental harshness. A follow-up exploration for the developmental implication of SPS change showed that children with higher SPS benefited more from the supportive environment by developing greater cognitive and behavioral functioning.

This latter phenomenon, sometimes termed bias to trust in testimony, has primarily been studied in children preschool-age and younger, presumably because reasoning capacities improve with age. Less attention has been paid to situations in which testimony bias lingers-one possibility is that children revert to a testimony bias under conditions of uncertainty. Here, participants (4 to 9 years old) searched for rewards and received testimony that varied in reliability. We find support for testimony bias beyond preschool-age, particularly for uncertain testimony. Children were sensitive to trial-by-trial uncertainty (Experiment 1 N = 102, 59 boys, 43 girls; the sample included nine Hispanic/Latinx, 93 non-Hispanic/Latinx participants, of whom six were Black/African American, seven were Asian American, eight were multiracial, 77 were White, and four indicated "other" or did not respond), and with uncertainty defined as a one-time, unexpected change in the testimony (Experiment 3 N = 129; 68 boys, 61 girls; the sample included 12 Hispanic/Latinx, 117 non-Hispanic/Latinx [10 Black/African American, four Asian American, nine multiracial, 103 White, and three "other"]). However, the impact of the testimony bias decreased with age. These effects were specific to the testimony coming from another person as opposed to resulting from a computer glitch (Experiment 2 N = 89, 52 boys, 37 girls; five Hispanic/Latinx, 80 non-Hispanic/Latinx, of whom one was Black/African American, three were Asian American, 15 were multiracial, 66 were White, and four did not report race). Taken together, these experiments provide evidence of a disproportionate influence of testimony, even in children with more advanced reasoning skills.

Participants were African American, Asian, Latinx, and White youth recruited at the start of middle school in 6th grade (N = 4,361; Mage = 11.33 years) and followed across the 3 years of middle school. School racial/ethnic diversity and the racial/ethnic representation of students in their academic classes, including honors classes, were examined as predictors of friendship preferences over time. Results from latent growth curve models revealed that same-race friendship preference increased over the course of middle school and was shaped by both the school and classroom racial/ethnic context, above and beyond availability. DZD9008 ic50 Greater school racial/ethnic diversity predicted steeper increases in same-race friendship preference over time for all racial/ethnic groups. However, there were interactions involving race/ethnicity when the analyses focused on how students were represented in their academic classes compared with school. African American and Asian youth who were underrepresented in honors classes showed steeper increases in same-race friendship preference over time. Implications for prejudice reduction and creating more inclusive school environments are discussed.

However, less is known about the relation between EFs and science achievement. The nature of this relation might be explained by the theory of mutualism, which states that development is the result of complex and interacting processes, in which growth in one domain influences growth in another domain. The present study examined the bidirectional associations between science achievement and children's cognitive flexibility and working memory in a nationally representative sample of children in the United States (Early Childhood Longitudinal Study Kindergarten Class of 2010-2011 [ECLS-K2011]; N = 18,174). Using random intercepts cross-lagged panel modeling, results revealed a heterogeneous pattern of associations between EF and science achievement, consistent with mutualism theory. Trait-like and construct stability emerged in the between-person and within-person estimates of EF and science. Cognitive flexibility and working memory in kindergarten each predicted science achievement in first grade. Science achievement at the beginning of first grade predicted cognitive flexibility at the end of first grade. There were also bidirectional associations between working memory and science achievement from the beginning to the end of the first grade year. Although effect sizes were small, findings reveal the complex interplay between EF and science achievement during early childhood and highlight a core tenet of mutualism theory-that small gains in academic and cognitive domains are positively associated with future skills and abilities within and across domains.

This study addresses this gap by utilizing a sample of 1,750 children (53% male; 47% White, 16% Black, 16% Hispanic, 8% Asian, and 13% other or multirace) from the Early Childhood Longitudinal Study-Birth Cohort (ECLS-B) to examine the interrelationships between behavioral (parent-reported prosocial skills and externalizing problems) and math skills (directly assessed) across the ages of 4, 5, and 6 years. Results from a random intercept cross-lagged panel model (RICLPM) revealed significant between-person associations between each of these skills over time. After controlling for these between-person differences, findings identified several significant within-person associations both between and within domains, with prosocial skills at age 4 predicting both prosocial and math skills at age 5. At age 5, math skills were predictive of future math and prosocial skills at age 6. Externalizing problems were not significantly associated with either of the other skills at any time points, but did predict continued externalizing problems from ages 5 to 6. Findings highlight the importance of supporting children's prosocial and math skills in conjunction with one another during early childhood prior to school entry.

Participants included two cohorts of children (N = 558; 51% male). Children in both cohorts were 4 years old (Cohort 1 M = 4.82 years, SD = .31; Cohort 2 M = 4.80 years, SD = .31). Forty-four percent of children were Black, 32% were White, 13% were Latino, 10% were Multiracial, and 1% were Asian. Monthly income ranged from $0-5,539 (M = $1,508.18, SD = $892.92). Two statistical methods were used to examine relations among constructs. The cross-lagged panel model revealed a mixed pattern of relations between behavioral self-regulation and two indicators of social-emotional functioning (social skills and behavior problems) over time. There were no significant relations among behavioral self-regulation and social-emotional functioning during the preschool year; however, evidence for bidirectional associations were found between the spring of preschool and the fall of kindergarten. There were no significant relations among behavioral self-regulation and behavior problems at any time point. Finally, there were bidirectional relations among social skills and behavior problems in preschool, but directional relations emerged after this time point. A second model that included random intercepts was also run with the cross-lagged paths. Results from this model indicated that the random intercepts between behavioral self-regulation, social skills, and behavior problems were significantly related. Implications for future research are discussed.

Results show an overall increase in sharing with age, and an overall correlation between children's social status among peers and their sharing behavior-however, across both age groups, this association was significant only in the in-group condition, not when the recipient child was an out-group member. Specifically, less accepted children behaved in a less prosocial manner only toward in-group members, not toward out-group ones. This suggests that situational factors and characteristics of the prospective recipient play an important part in the degree to which less socially accepted children are willing to act prosocially.

The aim of this replication study was to conduct an independent test of these findings with both concurrent and longitudinal data. Concurrent data for replication analyses were drawn from 4 projects, involving a total of 959 boys and 1,119 girls (ages 10 to 14) from Canada and the United States. Three samples reported participant ethnic descent Africa (12.1%), Asia (5.6%), Europe (65.3%), Latin America (12.1%), and Native North America (0.9%). Child and mother reports of mother-child relationship quality assayed (a) maternal social support (in 3 data sets), and (b) family cohesion and adaptability (in 2 data sets). Main effects were replicated but hypothesized buffering effects were not. Maternal social support and friend social support were independently associated with adolescent self-esteem, concurrently, but not longitudinally.
