Premature infants may be at risk for lower effortful control, and subsequent lower academic achievement, peer competence, and emotional and physical wellness throughout the lifespan. However, because ...prematurity is related to obstetrical and neonatal complications, it is unclear what may drive the effect. Effortful control also has a strong heritable component; therefore, environmental factors during pregnancy and the neonatal period may interact with genetic factors to predict effortful control development. In this study, we aimed to dissect the influences of genetics, prematurity, and neonatal and obstetrical complications on the development of effortful control from 12 months to 10 years using a twin cohort. This study used data from the Arizona Twin Project, an ongoing longitudinal study of approximately 350 pairs of twins. Twins were primarily Hispanic/Latinx (23.8%–27.1%) and non-Hispanic/Latinx White (53.2%–57.8%), and families ranged in socioeconomic status with around one third falling below or near the poverty line. Of the twins, 62.6% were born prematurely. Effortful control was assessed via parent report at six waves. There was not a significant relationship between gestational age and effortful control regardless of whether obstetrical and neonatal complications were controlled for. Biometric twin modeling revealed that the attentional focusing subdomain of effortful control was highly heritable. Gestational age did not moderate genetic and environmental estimates. Our findings help inform the risk assessment of prematurity and provide evidence for the differing etiology of each subdomain of effortful control and the strong role of genetics in effortful control development.

A deep understanding of any phenomenon requires knowing how its causal elements are related to one another. Here, we examine whether children treat causal structure as a metric for assessing ...similarity across superficially distinct events. In two experiments, we presented 156 4–7-year-olds (approximately 55% of participants identified as White, 29% as multiracial, and 12% as Asian) with three-variable narratives in which story events unfold according to a causal chain or a common effect structure. We then asked children to make judgments about which stories are the most similar. In Experiment 1, we presented all events in the context of simple, illustrated stories. In Experiment 2, we removed all low-level linguistic cues that may have supported children’s similarity judgments in Experiment 1 and used animated videos to support understanding of the causal elements in each story. Results indicated a gradual shift between 4 and 7 years in children’s use of causal structure as a metric of similarity between narratives: While we found that children as young as five were capable of correctly representing the causal structure of each story individually, only 6- and 7-year-olds relied on shared causal structure across stories when making similarity judgments. We discuss these findings in light of children’s developing causal and abstract reasoning and propose directions for future work.

Children with a history of behaviorally inhibited (BI) temperament face a heightened risk for anxiety disorders and often use control strategies that are less planful. Although these relations have ...been observed concurrently in early childhood, middle childhood, and adolescence, few studies leverage longitudinal data to examine long-term prospective relations between cognitive control and anxiety. Using longitudinal data from 149 adolescents (55% female; from predominantly White middle-class families), we assessed temperament in toddlerhood and cognitive control and anxiety at 4, 12, 15, and 18 years of age. At age 4, separate measures of task switching and inhibitory control were obtained via the Dimensional Change Card Sort and Stroop tasks, respectively. At 12, 15, and 18 years of age, planful control was assessed with the AX-Continuous Performance Test, and anxiety symptoms were assessed via self-report. Growth curve models revealed that children with greater inhibitory control at age 4, regardless of BI status, experienced a sharper increase in anxiety symptoms across adolescence. Children with heightened BI during early childhood displayed lower levels of planful control at age 12, but experienced a more rapid improvement in these skills across adolescence. Children with greater task switching ability at age 4 displayed higher levels of planful control at age 12, but experienced a smaller increase in these skills across adolescence. Finally, children’s growth rate for anxiety was unrelated to their growth rate for planful control. These findings reveal that early-life temperament, cognitive control, and anxiety remain interconnected across development, from toddlerhood to at least late adolescence.

Guided by developmental models examining the legacy of childhood caregiving environments, we examined the longitudinal pattern of associations between harsh parenting and children’s internalizing and ...externalizing symptoms across late childhood to late adolescence. Participants included 199 youth (48.7% female, 65.3% White, 32.2% Black, 2.5% biracial) and their mothers and fathers from a diverse range of socioeconomic backgrounds. The study utilized a multi-informant, longitudinal design including five waves of data (youths’ mean ages were 9, 10, 11, 17, and 18 across waves). Harsh parenting at Age 9 predicted higher levels of (a) externalizing symptoms at Ages 11, 17, and 18 and (b) internalizing symptoms at Ages 17 and 18. Developmental sensitivity analyses revealed that the magnitude of the more distal association between early harsh parenting and later internalizing and externalizing symptoms was statistically stronger as compared to more proximal associations. Bidirectional analyses revealed that externalizing symptoms at Age 9 predicted harsh parenting at Ages 9, 10, 11, 17, and 18. Whereas links between harsh parenting and internalizing symptoms were consistent with a sleeper effects model, links between harsh parenting and externalizing symptoms provided some support for both enduring and sleeper effects models. Findings inform an understanding of youth developmental sensitivity to harsh parenting and the downstream consequences of harsh parenting. Results have important translational implications, including testing the long-term efficacy of therapeutic programs.

This paper quantitatively examines the intergenerational effects of girl child marriage, or the developmental and health outcomes of children born to women who marry before age 18. The overall ...objective is to understand the mechanisms through which girl child marriage affects the health and well-being of children in sub-Saharan Africa, as well as the relative magnitude and impact of these mechanisms. We used data from 37,558 mother-child pairs identified through 16 national and sub-national cross-sectional surveys across sub-Saharan Africa conducted between 2010 and 2014 by the UNICEF Multiple Indicator Clusters Survey program. The Early Childhood Development Index was used to measure child development, and stunting was used to measure health. Using logistic regression, we found that the odds of being off-track for development and being stunted were 25% and 29% higher, respectively, for children born to women who married before age 18 compared to those whose mothers married later (p < 0.001). Geographic location and primary education, which were conceptualized as contextual factors, explained most of this relationship, controlling for country fixed-effects. In adjusted models, we found that early childbearing was not the sole pathway through which girl child marriage affected child development and health. Our final models revealed that disparities in advanced maternal education and wealth explained child development and stunting. We conclude that there are intergenerational consequences of girl child marriage on her child's well-being, and that through association with other contextual, socioeconomic, and biological factors, marrying early does matter for child development and health. Our findings resonate with existing literature and point toward important policy considerations for improving early childhood outcomes.
•Uniquely examines how girl child marriage affects child development and stunting.•Provides framework to conceptualize how girl child marriage affects child well-being.•Focuses on mechanisms explaining child outcomes associated with girl child marriage.•Reveals that early childbearing alone does not explain poor child outcomes.•Contributes to understanding health and rights issue in sub-Saharan Africa.
A central goal of research into language acquisition is explaining how, when learners generalize to new cases, they appropriately restrict their generalizations (e.g., to avoid producing ...ungrammatical utterances such as *the clown laughed the man; “*” indicates an ungrammatical form). The past 30 years have seen an unresolved debate between statistical preemption and entrenchment as explanations. Under preemption, the use of a verb in a particular construction (e.g., *the clown laughed the man) is probabilistically blocked by hearing that other verb constructions with similar meanings only (e.g., the clown made the man laugh). Under entrenchment, such errors (e.g., * the clown laughed the man) are probabilistically blocked by hearing any utterance that includes the relevant verb (e.g., by the clown made the man laugh and the man laughed). Across five artificial-language-learning studies, we designed a training regime such that learners received evidence for the (by the relevant hypothesis) ungrammaticality of a particular unattested verb/noun + particle combination (e.g., * chila + kem; * squeako + kem) via either preemption only or entrenchment only. Across all five studies, participants in the preemption condition (as per our preregistered prediction) rated unattested verb/noun + particle combinations as less acceptable for restricted verbs/nouns, which appeared during training, than for unrestricted, novel-at-test verbs/nouns, which did not appear during training, that is, strong evidence for preemption. Participants in the entrenchment condition showed no evidence for such an effect (and in 3/5 experiments, positive evidence for the null). We conclude that a successful model of learning linguistic restrictions must instantiate competition between different forms only where they express the same (or similar) meanings.

Verbal attention guidance is assumed to be an important cultural tool contributing to the development of culture-specific visual attention styles in childhood. We used a training approach to test ...whether verbal attention guidance in a 10 day app-based training that accentuates either analytic or holistic processing has the power to produce enduring effects on 6- to 7-year-old urban German children's (
= 42, 22 female, 20 male) attention in a picture description task, a single-choice recognition task and a change blindness task. Results indicate that verbal attention guidance is effective in influencing children's attention styles across indicators. These findings provide convergent evidence for the assumption that verbal attention guidance plays a central role in the long-term socialization of attention styles.

We propose an integrative model for the adaptation of immigrant-origin children and youth that combines ecological with risk and resilience frameworks. Immigrant-origin children and youth are now, ...and will continue to be, a diverse and demographically important segment of all postindustrial nations' populations. Synthesizing evidence across psychological, educational, and sociological disciplines produced since the seminal publication of García Coll et al.'s (1996) model, along with significant events such as a global refugee crisis, a sociopolitical "deportation nation" climate, and heightened xenophobia, we provide a model for understanding the current conditions immigrant-origin children and youth encounter as they develop. This new integrative conceptual model for addressing positive frameworks for adaptation provides a culturally relevant approach for understanding both the risks and resilience of this population. The model was designed to inform practice and future research in the service of immigrant-origin children and youth.
It is well established that children’s reading comprehension is driven, at least in part, by their awareness of morphemes, or the smallest units of meaning in language. The question of how it does so ...is largely open; this mechanistic knowledge would specify theories of reading comprehension and guide effective classroom instruction. We report here on a longitudinal study designed to test two candidate mechanisms by which morphological awareness might support the development of reading comprehension: use of morphemes to read words and to understand words, known as morphological decoding and analysis, respectively. We tracked the development of 221 children on key measures from Grades 3 to 5. These three-wave longitudinal data enabled us to test morphological decoding and analysis as mediators connecting morphological awareness to gains in reading comprehension over time. Structural equation modeling showed that morphological awareness contributed to gains in both morphological decoding and analysis. Critically, only morphological analysis mediated the contribution of morphological awareness to gains in reading comprehension between Grades 3 and 5. These findings elaborate predictions of the morphological pathways framework. Specifically, longitudinal modeling shows how morphological awareness supports children’s developing reading comprehension: by enabling the use of morphemes to read and understand words, with effects on the understanding of words supporting children’s growing skill in understanding texts. Evidence supporting these two specific mechanisms inspires the design of targeted teaching on morphemes toward the development of strong reading comprehension.
