This study's aims were to identify distinct classes of youth exhibiting differing joint trajectories of anxious solitude (AS) and peer adversities from early childhood to adolescence and to examine relations between trajectory classes and the development of internalizing problems. A sample of 383 children (193 girls) was followed from kindergarten (M_age = 5.56 years) through Grade 12 (M_age = 17.89). Measures of AS, peer group rejection and victimization, loneliness, self-esteem, and depression were repeatedly administered across this epoch. Results revealed multiple joint-trajectory classes characterized by varying combinations of AS and peer adversity, and children in these classes differed in the development of internalizing problems over time. Consistent with diathesis-stress hypotheses, two types of peer adversities (stressors), peer group rejection and peer victimization, moderated the relations between children's propensity to engage in AS (diathesis) and the development of specific internalizing problems, including loneliness, depression, and low self-esteem. These findings suggest that socially vulnerable children (i.e., those high in AS) are particularly prone to developing internalizing problems in the face of peer adversity.

Developmental cascades-the view that development in one domain can induce change in another-provide unique flexibility for researchers to examine relations among multiple behaviors. Research using this theoretical framework has demonstrated that changes in infant locomotor development are met with concomitant changes in infants' interactions with objects and caregivers. However, little is known about how infants' real-time locomotor actions organize these larger associations across developmental time. This study mapped the progression of one potential moment-to-moment cascade pathway linking changes in infant locomotion, access to objects and caregivers, and joint object play. We observed 30 infant-caregiver dyads during three monthly sessions across the transition to walking (M_{infant age} = 11.98 months, range = 8.74-14.86) and examined whether and how infants' real-time locomotor actions shaped the unfolding of the cascade. Infants moved more frequently in supported upright postures (i.e., cruising, supported walking) compared to crawling at the prewalking session and compared to walking at walk onset. However, infants preferred to walk after spending 1 month as walkers. Regardless of how they moved, infants regularly encountered objects and caregivers during everyday exploration. But there was an effect of locomotor posture on joint object play. Specifically, dyads were most likely to engage in object play after supported upright bouts at the prewalking and walk onset sessions, but at the final walking session, they were most likely to do so after walking bouts. Taken together, this in-depth examination of moment-to-moment cascades highlights the contributions of the many timescales that drive developmental processes.

Adolescence is a period of rapid social changes that may have important implications for the ways adolescents think, feel, and behave in their close relationships. According to family systems theory, adolescents' attachment-related changes have the potential to spread throughout their family system, leading to coordinated changes in parents' and adolescents' attachment styles over time. The present study analyzed data from 205 adolescents (M_ageT1 = 14.0, SD = 0.9; 44% female, 56% male; 51% White, 33% African American, 3% Hispanic/Latino, 1% Asian American, 12% another race/ethnicity) and their parents (196 mothers, 105 fathers; median household income_T1 = $100,000) who completed self-report measures of their general attachment styles annually for 5 years. Using a latent growth curve framework, we examined the extent of coordination among adolescents' and parents' long-term trajectories and shorter term fluctuations in attachment security. The results revealed a push-and-pull dynamic between mothers' and adolescents' long-term trajectories of attachment security. Mothers who reported higher initial levels of attachment anxiety tended to have adolescent children who reported higher initial levels of avoidance. Additionally, adolescents who increased in attachment avoidance over time tended to have mothers who increased in attachment anxiety. Mothers and fathers mirrored each other's patterns of attachment security as their children navigated their teenage years, reporting similar initial levels of attachment avoidance and synchronized shorter term fluctuations in attachment anxiety and avoidance across time.

Children's emotion knowledge encompasses abilities to recognize and label emotions in the service of positive adaptation. Drawing on a sociodemographically diverse sample of 250 children (50% female sex assigned at birth; M_{age_W1} = 49.02 months, SD = 2.99) and their maternal caregivers (55.6% Latina; 37.6% poverty), this study evaluated a multiple mediation model to integrate heretofore distinct bodies of research examining (a) parenting effects on the development of emotion knowledge and (b) emotion knowledge effects on socioemotional adaptation. Observations of maternal supportive presence at age 4 predicted increases in children's emotion recognition and labeling from ages 4 to 8. However, only emotion labeling skills explained children's behavioral adjustment outcomes with a significant pathway from supportive parenting at age 4 to fewer externalizing and internalizing behavior problems at age 10 via improved emotion labeling skills. These findings suggest that emotion knowledge, particularly labeling skills, partially explains the protective impact of supportive parenting on behavioral adaptation across childhood. Prevention and intervention efforts should target both supportive parenting practices and emotion knowledge skill development to support children's socioemotional functioning and reduce behavior problems.

Prior research documents that adults in Western cultures perceive others as more susceptible to social influence than themselves (Pronin et al., 2007). Study 1 (N = 318) investigated the cultural generalizability of this asymmetric perception effect by examining young adults in South Korea, where conformity is relatively valued, and a comparison sample of young adults in the United States. The results documented that, counter to theoretical accounts emphasizing the centrality of motivated reasoning, the self-other distinction was just as strong in South Korea as it was in the United States. Study 2 (N = 102) examined the development of this tendency among 6- to 12-year-old South Korean children and showed that this asymmetry is first present at around age 9. These findings suggest that asymmetric perceptions of conformity are robust and emerge over the course of development. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Both longer term developmental changes (increases in hostility, decreases in warmth) and lability (year-to-year fluctuations) in parent-child relationship quality across childhood and adolescence have been linked to adolescent externalizing behaviors. Using a prospective longitudinal study of 561 children who were adopted into nonrelative families at birth (57% male, 56% White, 19% multiracial, 13% Black, 11% Hispanic) where parental warmth and hostility reflect environmental influences or child-evoked reactions, we examined associations between parent-child relationship measures and externalizing behaviors at age 11 and across adolescence (i.e., from age 11 to 13-15 years). Because studies considering gene-environment interplay especially in associations between lability and child externalizing behaviors are sparse and parent-child relationship measures support the intergenerational transmission of psychopathology, we also tested whether parent psychopathology of both adoptive parent (AP; environmental intergenerational transmission) and birth parents (genetic intergenerational transmission) moderated these associations in multivariate regression models. Findings generally supported more effects of fathers' than mothers' warmth and hostility. Although there were some linear associations of increased lability with externalizing behaviors, these did not persist in the context of a multivariate model. Associations between both parents' increasing hostility across childhood on age 11 externalizing behaviors and for fathers increasing hostility and decreasing warmth on increases in externalizing behaviors across adolescence more likely reflect a combination of bidirectional evocative and parenting environmental associations than purely parenting environmental transmission. Moderation by parent psychopathology was sparse, and sensitivity tests revealed no differences by child sex. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Major amendments in neonatal care have been introduced in recent decades. It is important to understand whether these amendments improved the cognitive sequelae of preterm children. Through a large-scale meta-analysis, we explored the association between prematurity-related complications, neonatal care quality, and cognitive development from birth until 7 years. MEDLINE, APA PsycInfo, and EBSCO were searched. Peer-reviewed studies published between 1970 and 2022 using standardized tests were included. We evaluated differences between preterm and full-term children in focal developmental domains using random-effects meta-analyses. We analyzed data from 161 studies involving 39,799 children. Preterm birth was associated with inferior outcomes in global cognitive development (standardized mean difference = -0.57, 95% CI [-0.63, -0.52]), as well as in language/communication, visuospatial, and motor performance, reflecting mean decreases of approximately 7.3 to 9.3 developmental/intelligence quotients. Extreme prematurity, neonatal pulmonary morbidities, and older assessment age in very-to-extreme preterm cohorts were associated with worse outcomes. Contemporary neonatal medical and developmental care were associated with transient improvements in global cognitive development, evident until 2 to 3 years of age but not after. Blinding of examiners to participants' gestational background was associated with poorer outcomes in preterm cohorts, suggesting the possibility of a "compassion bias." The results suggest that preterm birth remains associated with poorer cognitive development in early childhood, especially following pulmonary diseases and very-to-extreme preterm delivery. Importantly, deficits become more pervasive with age, but only after births before 32 gestational weeks and not in moderate-to-late preterm cohorts. Care advancements show promising signs of promoting resiliency in the early years but need further refinements throughout childhood. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Parent-child coregulation, the active dyadic adaptation of biological states, behaviors, and emotions, is an important developmental process. Especially in challenging situations, children need coregulatory support from their parents, which supports the formation of their self-regulation skills. While research has established that coregulation occurs in various contexts across the developmental period, less is known about what constitutes coregulation in terms of child adjustment and the contextual factors that affect coregulation. This systematic review examined what constitutes parent-child coregulation in response to an experimentally induced challenge and in association with child socioemotional outcomes. Systematic searches were conducted in Web of Science, APA PsycInfo, and PubMed, adhering to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Fourteen full-text, peer-reviewed, empirical journal articles that were available in English were included. Children were between the ages of 3 and 12 (M_age = 5.37 years, 44%-100% male, 6.3%-90% White). Findings indicate that behavioral and emotional coregulation in response to challenge is positively associated with better child self-regulation. Coregulation associated with positive child outcomes seems to be characterized by high flexibility and dyadic synchrony in mutually responsive and engaged states. Findings regarding physiological coregulation suggest that high levels of physiological synchrony can be maladaptive for child outcomes in the presence of risk (e.g., poverty, maltreatment). In addition, this review highlighted the current ambiguity surrounding the diverse terminologies and concepts used to measure coregulation. The findings of this review reveal a significant link between parent-child coregulation and child socioemotional outcomes, while supporting the idea that contextual factors need to be considered to understand its significance.

For three decades, researchers have assessed children's genetic essentialism through an "Adoption Task," probing their beliefs about whether adopted babies grow up to resemble their birthparents or adoptive parents. The present study investigates these beliefs among children who were themselves adopted or donor-conceived (i.e., who share genetic material with neither or one parent, respectively; "ADC"), comparing them with children who were traditionally-conceived (i.e., who share genetic material with two parents; "TC"). Children (n = 95, 4-8 years old, 30ADC/65TC, 34M/59F/2NB, 55 White / 35 of color / five did not report) completed five trials of an Adoption Task concerning five personal characteristics (hair color, spoken language, personality, interests, and intelligence). Across trials, ADC children made fewer essentialist judgments than TC children (η_p² = .07); the odds of an essentialist response were threefold greater among TC than ADC participants. Exploratory analyses revealed that with age, children's essentialist judgments became increasingly differentiated across different characteristics (e.g., increasingly divergent views of the genetic basis of hair color vs. spoken language), and that this differentiation was more pronounced in the ADC than the TC sample. No differences were observed in the genetic-essentialist views of ADC and TC children's parents, suggesting that the mechanism underlying effects was children's own sense-making capacities. Whereas nature and nurture are confounded for TC children, these factors are decoupled for ADC children, supporting them in building their causal theories. Cognitive, developmental, and social implications are discussed, along with translational implications for ADC children and their families.

The expression of intellectual humility-publicly admitting confusion, ignorance, and mistakes-can benefit individuals, but can it also benefit others? Five studies tested the hypothesis that teachers' expressions of intellectual humility would boost U.S. students' motivation and engagement in learning. In two pilot studies (one preregistered, combined N = 231), adults (50% women; 58% White, 25% Black) and adolescents (48% girls; 53% White, 33% Hispanic) anticipated being most comfortable expressing intellectual humility and interested in a hypothetical math class when a teacher's class description modeled the expression of intellectual humility relative to when the teacher recommended that students show intellectual humility or mentioned nothing about intellectual humility. Two fully powered, preregistered experiments with undergraduates (both 50% women; Study 3: 58% Asian, 17% Hispanic or Latinx, 16% White; Study 4: 53% White, 16% Asian, 16% Hispanic or Latinx; combined N = 767) replicated these effects and identified three mechanisms: an increase in a sense of acceptance by the teacher, an increase in the sense of belonging with peers, and a decrease in the belief that failure hurts learning. Study 5 (preregistered) revealed that high school students (51% girls; 92% White; N = 411) were more interested and engaged in their classes when they perceived their teachers to be more intellectually humble, with the largest benefits for young women. Longitudinally, teachers' modeling intellectual humility predicted changes in students' grades via a willingness to express intellectual humility. Teachers' intellectual humility may benefit students' interest, engagement, and learning in school. (PsycInfo Database Record (c) 2024 APA, all rights reserved).
