A Developmental Perspective on Executive Function

Abstract: This review article examines theoretical and methodological issues in the construction of a developmental perspective on executive function (EF) in childhood and adolescence. Unlike most reviews of EF, which focus on preschoolers, this review focuses on studies that include large age ranges. It outlines the development of the foundational components of EF—inhibition, working memory, and shifting. Cognitive and neurophysiological assessments show that although EF emerges during the first few years of life, it continues to strengthen significantly throughout childhood and adolescence. The components vary somewhat in their developmental trajectories. The article relates the findings to long-standing issues of development (e.g., developmental sequences, trajectories, and processes) and suggests research needed for constructing a developmental framework encompassing early childhood through adolescence.

From External Regulation to Self‐Regulation: Early Parenting Precursors of Young Children’s Executive Functioning

Abstract: In keeping with proposals emphasizing the role of early experience in infant brain development, this study investigated the prospective links between quality of parent–infant interactions and subsequent child executive functioning (EF), including working memory, impulse control, and set shifting. Maternal sensitivity, mind-mindedness and autonomy support were assessed when children were 12 to 15 months old (N = 80). Child EF was assessed at 18 and 26 months. All three parenting dimensions were found to relate to child EF. Autonomy support was the strongest predictor of EF at each age, independent of general cognitive ability and maternal education. These findings add to previous results on child stress-response systems in suggesting that parent–child relationships may play an important role in children’s developing self-regulatory capacities.

The significance of insecure attachment and disorganization in the development of children's externalizing behavior: a meta-analytic study.

Abstract: This study addresses the extent to which insecure and disorganized attachments increase risk for externalizing problems using meta-analysis. From 69 samples (N = 5,947), the association between insecurity and externalizing problems was significant, d = 0.31 (95% CI: 0.23, 0.40). Larger effects were found for boys (d = 0.35), clinical samples (d = 0.49), and from observation-based outcome assessments (d = 0.58). Larger effects were found for attachment assessments other than the Strange Situation. Overall, disorganized children appeared at elevated risk (d = 0.34, 95% CI: 0.18, 0.50), with weaker effects for avoidance (d = 0.12, 95% CI: 0.03, 0.21) and resistance (d = 0.11, 95% CI: −0.04, 0.26). The results are discussed in terms of the potential significance of attachment for mental health.

A Unified Theory of Development: A Dialectic Integration of Nature and Nurture

Abstract: The understanding of nature and nurture within developmental science has evolved with alternating ascendance of one or the other as primary explanations for individual differences in life course trajectories of success or failure. A dialectical perspective emphasizing the interconnectedness of individual and context is suggested to interpret the evolution of developmental science in similar terms to those necessary to explain the development of individual children. A unified theory of development is proposed to integrate personal change, context, regulation, and representational models of development.

Epigenetics and the biological definition of gene x environment interactions.

Abstract: Variations in phenotype reflect the influence of environmental conditions during development on cellular functions, including that of the genome. The recent integration of epigenetics into developmental psychobiology illustrates the processes by which environmental conditions in early life structurally alter DNA, providing a physical basis for the influence of the perinatal environmental signals on phenotype over the life of the individual. This review focuses on the enduring effects of naturally occurring variations in maternal care on gene expression and phenotype to provide an example of environmentally driven plasticity at the level of the DNA, revealing the interdependence of gene and environmental in the regulation of phenotype.

How the Timing and Quality of Early Experiences Influence the Development of Brain Architecture

Abstract: Early life events can exert a powerful influence on both the pattern of brain architecture and behavioral development. In this study a conceptual framework is provided for considering how the structure of early experience gets "under the skin." The study begins with a description of the genetic framework that lays the foundation for brain development, and then proceeds to the ways experience interacts with and modifies the structures and functions of the developing brain. Much of the attention is focused on early experience and sensitive periods, although it is made clear that later experience also plays an important role in maintaining and elaborating this early wiring diagram, which is critical to establishing a solid footing for development beyond the early years.

Do Effects of Early Child Care Extend to Age 15 Years? Results From the NICHD Study of Early Child Care and Youth Development

Abstract: Relations between nonrelative child care (birth to 4½ years) and functioning at age 15 were examined (N = 1,364). Both quality and quantity of child care were linked to adolescent functioning. Effects were similar in size as those observed at younger ages. Higher quality care predicted higher cognitive–academic achievement at age 15, with escalating positive effects at higher levels of quality. The association between quality and achievement was mediated, in part, by earlier child-care effects on achievement. High-quality early child care also predicted youth reports of less externalizing behavior. More hours of nonrelative care predicted greater risk taking and impulsivity at age 15, relations that were partially mediated by earlier child-care effects on externalizing behaviors.

Early‐Childhood Poverty and Adult Attainment, Behavior, and Health

Abstract: This article assesses the consequences of poverty between a child’s prenatal year and 5th birthday for several adult achievement, health, and behavior outcomes, measured as late as age 37. Using data from the Panel Study of Income Dynamics (1,589) and controlling for economic conditions in middle childhood and adolescence, as well as demographic conditions at the time of the birth, findings indicate statistically significant and, in some cases, quantitatively large detrimental effects of early poverty on a number of attainment-related outcomes (adult earnings and work hours). Early-childhood poverty was not associated with such behavioral measures as out-of-wedlock childbearing and arrests. Most of the adult earnings effects appear to operate through early poverty’s association with adult work hours.

Parent Involvement and Children’s Academic and Social Development in Elementary School

Abstract: Data from the National Institute of Child Health and Human Development (NICHD) Study of Early Childcare and Youth Development (N = 1,364) were used to investigate children's trajectories of academic and social development across 1st, 3rd, and 5th grades. Hierarchical linear modeling was used to examine within- and between-child associations among maternal and teacher reports of parent involvement and children's standardized achievement scores, social skills, and problem behaviors. Findings suggest that within-child improvements in parent involvement predict declines in problem behaviors and improvements in social skills but do not predict changes in achievement. Between-child analyses demonstrated that children with highly involved parents had enhanced social functioning and fewer behavior problems. Similar patterns of findings emerged for teacher and parent reports of parent involvement. Implications for policy and practice are discussed.

Pathways to mathematics: longitudinal predictors of performance.

Abstract: A model of the relations among cognitive precursors, early numeracy skill, and mathematical outcomes was tested for 182 children from 4.5 to 7.5 years of age. The model integrates research from neuroimaging, clinical populations, and normal development in children and adults. It includes 3 precursor pathways: quantitative, linguistic, and spatial attention. These pathways (a) contributed independently to early numeracy skills during preschool and kindergarten and (b) related differentially to performance on a variety of mathematical outcomes 2 years later. The success of the model in accounting for performance highlights the need to understand the fundamental underlying skills that contribute to diverse forms of mathematical competence.

The timing of prenatal exposure to maternal cortisol and psychosocial stress is associated with human infant cognitive development.

Abstract: The consequences of prenatal maternal stress for development were examined in 125 full-term infants at 3, 6, and 12 months of age. Maternal cortisol and psychological state were evaluated 5 times during pregnancy. Exposure to elevated concentrations of cortisol early in gestation was associated with a slower rate of development over the 1st year and lower mental development scores at 12 months. Elevated levels of maternal cortisol late in gestation, however, were associated with accelerated cognitive development and higher scores at 12 months. Elevated levels of maternal pregnancy-specific anxiety early in pregnancy were independently associated with lower 12-month mental development scores. These data suggest that maternal cortisol and pregnancy-specific anxiety have programming influences on the developing fetus.

Building a new biodevelopmental framework to guide the future of early childhood policy.

Abstract: Four decades of early childhood policy and program development indicate that evidence-based interventions can improve life outcomes, and dramatic advances in the biological and behavioral sciences now provide an opportunity to augment those impacts. The challenge of reducing the gap between what we know and what we do to promote the healthy development of young children is to view current best practices as a starting point and to leverage scientific concepts to inspire fresh thinking. This article offers an integrated, biodevelopmental framework to promote greater understanding of the antecedents and causal pathways that lead to disparities in health, learning, and behavior in order to inform the development of enhanced theories of change to drive innovation in policies and programs.

Biological sensitivity to context: the interactive effects of stress reactivity and family adversity on socioemotional behavior and school readiness.

Abstract: This study examined the direct and interactive effects of stress reactivity and family adversity on socioemotional and cognitive development in three hundred and thirty-eight 5- to 6-year-old children. Neurobiological stress reactivity was measured as respiratory sinus arrhythmia and salivary cortisol responses to social, cognitive, sensory, and emotional challenges. Adaptation was assessed using child, parent, and teacher reports of externalizing symptoms, prosocial behaviors, school engagement, and academic competence. Results revealed significant interactions between reactivity and adversity. High stress reactivity was associated with more maladaptive outcomes in the context of high adversity but with better adaption in the context of low adversity. The findings corroborate a reconceptualization of stress reactivity as biological sensitivity to context by showing that high reactivity can both hinder and promote adaptive functioning.

Toddlers' prosocial behavior: from instrumental to empathic to altruistic helping.

Abstract: The study explored how the meaning of prosocial behavior changes over toddlerhood. Sixty-five 18- and 30-month-olds could help an adult in 3 contexts: instrumental (action based), empathic (emotion based), and altruistic (costly). Children at both ages helped readily in instrumental tasks. For 18-month-olds, empathic helping was significantly more difficult than instrumental helping and required greater communication from the adult about her needs. Altruistic helping, which involved giving up an object of the child’s own, was the most difficult for children at both ages. Findings suggest that over the 2nd year of life, prosocial behavior develops from relying on action understanding and explicit communications to understanding others’ emotions from subtle cues. Developmental trajectories of social-cognitive and motivational components of early helping are discussed.

Integrating Different Perspectives on Socialization Theory and Research: A Domain-Specific Approach.

Abstract: There are several different theoretical and research approaches to the study of socialization, characterized by frequently competing basic tenets and apparently contradictory evidence. As a way of integrating approaches and understanding discrepancies, it is proposed that socialization processes be viewed from a domain perspective, with each domain characterized by a particular form of social interaction between the object and agent of socialization and by specific socialization mechanisms and outcomes. It is argued that this approach requires researchers to identify the domain of social interaction they are investigating, to understand that phenotypically similar behaviors may belong to different domains, and to acknowledge that caregivers who are effective in one type of interaction may not be effective in another.

Neurodevelopmental Effects of Early Deprivation in Postinstitutionalized Children

Abstract: The neurodevelopmental sequelae of early deprivation were examined by testing (N = 132) 8- and 9-year-old children who had endured prolonged versus brief institutionalized rearing or rearing in the natal family. Behavioral tasks included measures that permit inferences about underlying neural circuitry. Children raised in institutionalized settings showed neuropsychological deficits on tests of visual memory and attention, as well as visually mediated learning and inhibitory control. Yet, these children performed at developmentally appropriate levels on similar tests where auditory processing was also involved and on tests assessing executive processes such as rule acquisition and planning. These findings suggest that specific aspects of brain-behavioral circuitry may be particularly vulnerable to postnatal experience.

On the progression and stability of adolescent identity formation: a five-wave longitudinal study in early-to-middle and middle-to-late adolescence.

Abstract: This study examined identity development in a 5-wave study of 923 early-to-middle and 390 middle-to-late adolescents thereby covering the ages of 12–20. Systematic evidence for identity progression was found: The number of diffusions, moratoriums, and searching moratoriums (a newly obtained status) decreased, whereas the representation of the high-commitment statuses (2 variants of a [fore]closed identity: “early closure” and “closure,” and achievement) increased. We also found support for the individual difference perspective: 63% of the adolescents remained in the same identity status across the 5 waves. Identity progression was characterized by 7 transitions: diffusion → moratorium, diffusion → early closure, moratorium → closure, moratorium → achievement, searching moratorium → closure, searching moratorium → achievement, and early closure → achievement.

Parent discipline practices in an international sample: associations with child behaviors and moderation by perceived normativeness

Abstract: This study examined the associations of 11 discipline techniques with children’s aggressive and anxious behaviors in an international sample of mothers and children from 6 countries and determined whether any significant associations were moderated by mothers’ and children’s perceived normativeness of the techniques. Participants included 292 mothers and their 8- to 12-year-old children living in China, India, Italy, Kenya, Philippines, and Thailand. Parallel multilevel and fixed effects models revealed that mothers’ use of corporal punishment, expressing disappointment, and yelling were significantly related to more child aggression symptoms, whereas giving a time-out, using corporal punishment, expressing disappointment, and shaming were significantly related to greater child anxiety symptoms. Some moderation of these associations was found for children’s perceptions of normativeness.

The differential impacts of early physical and sexual abuse and internalizing problems on daytime cortisol rhythm in school-aged children.

Abstract: The impact of early physical and sexual abuse (EPA/SA) occurring in the first 5 years of life was investigated in relation to depressive and internalizing symptomatology and diurnal cortisol regulation. In a summer camp context, school-aged maltreated (n = 265) and nonmaltreated (n = 288) children provided morning and late afternoon saliva samples on 5 consecutive days. Child self-report and adult observer reports of child internalizing and depressive symptoms were obtained. Children experiencing EPA/SA and high depressive or internalizing symptoms uniquely exhibited an attenuated diurnal decrease in cortisol, indicative of neuroendocrine dysregulation. These results were specific to EPA/SA rather than later onset physical or sexual abuse or early occurring neglect or emotional maltreatment.

Children's classroom engagement and school readiness gains in prekindergarten.

Abstract: Child engagement in prekindergarten classrooms was examined using 2,751 children (mean age = 4.62) enrolled in public prekindergarten programs that were part of the Multi-State Study of Pre-Kindergarten and the State-Wide Early Education Programs Study. Latent class analysis was used to classify children into 4 profiles of classroom engagement: free play, individual instruction, group instruction, and scaffolded learning. Free play children exhibited smaller gains across the prekindergarten year on indicators of language/literacy and mathematics compared to other children. Individual instruction children made greater gains than other children on the Woodcock Johnson Applied Problems. Poor children in the individual instruction profile fared better than nonpoor children in that profile; in all other snapshot profiles, poor children fared worse than nonpoor children.

Placement in Foster Care Enhances Quality of Attachment Among Young Institutionalized Children

Abstract: This study examined classifications of attachment in 42-month-old Romanian children (N = 169). Institutionalized since birth, children were assessed comprehensively, randomly assigned to care as usual (CAU) or to foster care, and compared to family-reared children. Attachment classifications for children in foster care were markedly different from those in the CAU. Importantly, children placed in foster care before 24 months were more likely to have secure attachments and if placed earlier were less likely to have disorganized or insecure-other attachments. Cognitive status predicted greater likelihood of organized attachment in the CAU and greater likelihood of secure attachment in the foster care and never-institutionalized groups. Foster care is an important intervention to reduce the adverse effects following early deprivation.

Children With Disabilities in the Context of Disaster: A Social Vulnerability Perspective

Abstract: An estimated 200 million children worldwide experience various forms of disability This critical review extrapolates from existing literature in 2 distinct areas of scholarship: one on individuals with disabilities in disaster, and the other on children in disaster The extant literature suggests that various factors may contribute to the physical, psychological, and educational vulnerability of children with disabilities in disaster, including higher poverty rates, elevated risk exposure, greater vulnerability to traumatic loss or separation from caregivers, more strain on parents, and poor postdisaster outcomes, unless medical, familial, social, and educational protections are in place and vital social networks are quickly reestablished Future research needs are outlined in the conclusion

Sierra Leone's former child soldiers: a follow-up study of psychosocial adjustment and community reintegration.

Abstract: This is the first prospective study to investigate psychosocial adjustment in male and female former child soldiers (ages 10–18; n = 156, 12% female). The study began in Sierra Leone in 2002 and was designed to examine both risk and protective factors in psychosocial adjustment. Over the 2-year period of follow-up, youth who had wounded or killed others during the war demonstrated increases in hostility. Youth who survived rape not only had higher levels of anxiety and hostility but also demonstrated greater confidence and prosocial attitudes at follow-up. Of the potential protective resources examined, improved community acceptance was associated with reduced depression at follow-up and improved confidence and prosocial attitudes regardless of levels of violence exposure. Retention in school was also associated with greater prosocial attitudes.

Categorization in 3- and 4-month-old infants: an advantage of words over tones.

Abstract: Neonates prefer human speech to other nonlinguistic auditory stimuli. However, it remains an open question whether there are any conceptual consequences of words on object categorization in infants younger than 6 months. The current study examined the influence of words and tones on object categorization in forty-six 3- to 4-month-old infants. Infants were familiarized to different exemplars of a category accompanied by either a labeling phrase or a tone sequence. In test, infants viewed novel category and new within-category exemplars. Infants who heard labeling phrases provided evidence of categorization at test while infants who heard tone sequences did not, suggesting that infants as young as 3 months of age treat words and tones differently vis-a-vis object categorization.

Family Socioeconomic Status and Consistent Environmental Stimulation in Early Childhood

Abstract: The transition into school occurs at the intersection of multiple environmental settings. This study applied growth curve modeling to a sample of 1,364 American children, followed from birth through age 6, who had been categorized by their exposure to cognitive stimulation at home and in preschool child care and 1st-grade classrooms. Of special interest was the unique and combined contribution to early learning of these 3 settings. Net of socioeconomic selection into different settings, children had higher math achievement when they were consistently stimulated in all 3, and they had higher reading achievement when consistently stimulated at home and in child care. The observed benefits of consistent environmental stimulation tended to be more pronounced for low-income children.

Young Children Selectively Avoid Helping People With Harmful Intentions

Abstract: Two studies investigated whether young children are selectively prosocial toward others, based on the others' moral behaviors. In Study 1 (N = 54), 3-year-olds watched 1 adult (the actor) harming or helping another adult. Children subsequently helped the harmful actor less often than a third (previously neutral) adult, but helped the helpful and neutral adults equally often. In Study 2 (N = 36), 3-year-olds helped an actor who intended but failed to harm another adult less often than a neutral adult, but helped an accidentally harmful and a neutral adult equally often. Children's prosocial behavior was thus mediated by the intentions behind the actor's moral behavior, irrespective of outcome. Children thus selectively avoid helping those who cause--or even intend to cause--others harm.

The complex relation between bullying, victimization, acceptance, and rejection: Giving special attention to status, affection, and sex differences

Abstract: To understand the complex nature of bullies' acceptance and rejection, this article considered goal-framing effects of status and affection as they relate to the gender of the bully (male vs. female bullies), the target (male vs. female victims), and the evaluator (acceptance and rejection from male vs. female classmates). The hypotheses were tested with data from a social network questionnaire conducted in 26 elementary school classes (N = 481 children; M(age) = 10.5 years). The findings revealed that bullies were only rejected by those for whom they were a potential threat and that bullies generally chose their victims so as to minimize loss of affection by choosing victims who were not likely to be defended by significant others.

Developmental patterns in decision-making autonomy across middle childhood and adolescence: European American parents' perspectives

Abstract: Longitudinal patterns in parents' reports of youth decision-making autonomy from ages 9 to 20 were examined in a study of 201 European American families with 2 offspring. Multilevel modeling analyses revealed that decision-making autonomy increased gradually across middle childhood and adolescence before rising sharply in late adolescence. Social domain theory was supported by analyses of 8 decision types spanning prudential, conventional, personal, and multifaceted domains. Decision making was higher for girls, youth whom parents perceived as easier to supervise, and youth with better educated parents. Firstborns and secondborns had different age-related trajectories of decision-making autonomy. Findings shed light on the developmental trajectories and family processes associated with adolescents' fundamental task of gaining autonomy.

Disasters and Their Impact on Child Development: Introduction to the Special Section

Abstract: Disasters touch the lives of millions of children every year in many forms. These include natural disasters such as earthquakes, hurricanes, tornadoes, fires, or floods; human-made disasters of armed conflict, genocide, industrial accidents, or terrorism; and disease outbreaks. Interest in the impact of disasters on children among scientists dates back decades to the beginnings of research into risk and resilience in development (Garmezy, 1985; Garmezy & Rutter, 1983). For many years, only a small number of scattered studies of disasters were published on young people, often in the wake of a major catastrophe, such as the Buffalo Creek disaster (Erikson, 1978; Green et al., 1991; Newman, 1976), World War II and the Holocaust (Freud & Burlingham, 1943; Moscovitz, 1985), or a major fire (McFarlane, 1987). In the beginning of the 21st century, with the rise in international terrorism, concerns about flu pandemic, an alarming sequence of natural and human-designed disasters around the world, and globalization of media coverage, there is increasing attention to the consequences of disaster for children and youth (La Greca, Silverman, Vernberg, & Roberts, 2002; Masten & Obradovic, 2008; Osofsky, Osofsky, & Harris, 2007; Sagi-Schwarz, Seginer, & Abdeen, 2008). Research into disasters has accelerated despite inherent difficulties in conducting research in the context of catastrophic events. Given the importance of understanding how different types of disasters may impact development for children and families, it was timely to devote a special section of this journal to the impact of disasters on child development. The goal of the special section on disasters and child development was to provide an opportunity for researchers around the world to examine how disasters of nature and human design might affect children of different ages, experiences, cultures, and contexts, as well as how exposure to a disaster may alter developmental processes or developmental trajectories. Potential contributors were invited to submit a letter of intent by January 15, 2008, and 67 letters for different possible contributions were received. We invited 39 potential contributors to submit full manuscripts for review by May 1, 2008. The 15 articles comprising this special section represent 22% of the submitted letters of intent and 45% of the manuscripts that were submitted for review. The process of review was complicated by the diversity of the submissions in terms of disaster types and contexts, ages of disaster victims, nationality of authors, disciplinary approach, methods, and focus of the articles (e.g., empirical, conceptual, review, commentary). As editors for this special section, we strove to capture a broad representation of contemporary international scholarship from among the submissions that would reflect the diversity in the field. We were well aware of the challenges of conducting research in the context of disaster (discussed further below) and the constraints posed by ethical and practical dilemmas. In some cases, a study represents rare data obtained by methods that may not meet typical standards of scientific rigor because of the study context (e.g., naturalistic studies in the field or remote locations after a disaster). In all cases, we based the editorial decisions on our judgment of the potential value and unique contribution of the article in the context of current knowledge.

Posttraumatic Resilience in Former Ugandan Child Soldiers

Abstract: The present research examines posttraumatic resilience in extremely exposed children and adolescents based on interviews with 330 former Ugandan child soldiers (age = 11-17, female = 48.5%). Despite severe trauma exposure, 27.6% showed posttraumatic resilience as indicated by the absence of posttraumatic stress disorder, depression, and clinically significant behavioral and emotional problems. Among these former child soldiers, posttraumatic resilience was associated with lower exposure to domestic violence, lower guilt cognitions, less motivation to seek revenge, better socioeconomic situation in the family, and more perceived spiritual support. Among the youth with significant psychopathology, many of them had symptoms extending beyond the criteria for posttraumatic stress disorder, in keeping with the emerging concept of developmental trauma disorder. Implications for future research, intervention, and policy are discussed.
