Annual Review of Developmental Psychology - Volume 3, 2021

The Annual Review of Developmental Psychology presents a conversation with Professor Sir Michael Rutter, held remotely in the time of COVID but nonetheless wonderfully revealing of who this incredible scholar is and how he thinks. The contributions he has made to our understanding of child development are so vast and varied as to almost defy description. Erudite, articulate, and rigorous in his science, Michael Rutter is also deeply compassionate, caring, and outcome oriented. With training in medicine, neurology, pediatrics, and psychiatry, he held the first child psychiatry appointment in the United Kingdom and set up both the MRC Child Psychiatry Research Unit and the MRC Social, Genetic & Developmental Psychiatry Centre (SGDP). Unfortunately, Sir Michael passed away on October 23, 2021 while this article was in press. We feel fortunate to have had the opportunity to get to know Sir Michael, and to share this interview with you.

Current silo-based diagnostic systems for mental disorders lack utility and fail to fulfil a fundamental purpose of diagnosis: to guide treatment planning and predict outcomes. Diagnostic reform has gained momentum, and clinical staging has emerged as a promising framework to improve the precision of diagnosis, particularly in early illness stages, and fill current gaps in linking diagnosis to more personalized and effective intervention, prognosis, and neurobiological markers. Transdiagnostic clinical staging recognizes that the early development of mental ill-health is marked by substantial fluidity and that symptoms may, although not inevitably, evolve into more stable diagnosable syndromes. Staging facilitates the selection of interventions that are proportionate to the current need and risk of illness progression and provides an efficient framework to organize biomarker data and guide service delivery. Here, we provide an overview of transdiagnostic clinical staging and summarize key evidence supporting its ability to integrate biomarkers and guide mental health care.

Neonates show broad-based, universal speech perception abilities, allowing them to acquire any language. Moreover, an increasing body of research shows that prenatal experience with speech, which is a low-pass signal mainly preserving prosody, already shapes those abilities. In this review, we first provide a summary of the empirical evidence available today on newborns’ universal and experience-modulated speech perception abilities. We then interpret these findings in a new framework, focusing on the role of the prenatal prosodic experience in speech perception development. We argue that the chronological sequence of infants’ experience with speech, starting before birth with a low-pass filtered signal and continuing with the full-band signal after birth, sets up the prosodic hierarchy and a cascade of embedded neural oscillations as its brain correlate, laying the foundations for language acquisition. Prosody, constituting infants’ very first experience with language, may thus play a fundamental role in speech perception and language development.

Across development, interactions between value-based learning and memory processes promote the formation of mental models that enable flexible goal pursuit. Value cues in the environment signal information that may be useful to prioritize in memory; these prioritized memories in turn form the foundation of structured knowledge representations that guide subsequent learning. Critically, neural and cognitive component processes of learning and memory undergo marked shifts from infancy to adulthood, leading to developmental change in the construction of mental models and how they are used to guide goal-directed behavior. This review explores how changes in reciprocal interactions between value-based learning and memory influence adaptive behavior across development and highlights avenues for future research.

We review work on the development of children's and adolescents’ achievement motivation, focusing on recent advances in the empirical work in the field and commenting on the status of current theories prominent in the literature. We first focus on the main theories guiding the field and the development of motivational beliefs, values, and goals; intrinsic and extrinsic motivation; identity and motivation; and motivation and emotion. We provide our views on future directions for theory development and what we believe are the critical next steps in developmental research. We then discuss the burgeoning intervention work designed to enhance different aspects of children's motivation: their competence beliefs and mindsets, intrinsic motivation, valuing of achievement, and growth mindsets. We also provide suggestions for next steps in this area in order to guide the field forward. We close with a brief consideration of neuroscience approaches to motivation.

This review offers a theoretical and practical guide to assessing a broad range of personality differences in middle childhood and adolescence. We begin by highlighting normative changes in middle childhood and adolescence that shape the personality differences youth display. We then review the assessment of four broad domains of personality in children and adolescents: temperament and personality traits, social-emotional-behavioral (SEB) skills, motivation and agency (including goals, values, and interests), and narrative identity. We conclude by offering a primer of general principles for assessing personality in childhood and adolescence: pursuing ongoing construct validation, weighing strengths and weaknesses of various informants and data sources, combining measures, addressing heterotypic continuity, obtaining child self-reports, and pursuing promising new directions. It is well worth taking on the challenges inherent in assessing these individual differences because children and adolescents display a rich, complex, and meaningful set of still-changing personality differences that shape the course of their lives.

Success in life is linked to executive functions, a collection of cognitive processes that support goal-directed behaviors. Executive functions is an umbrella term related to cognitive control, self-control, and more. Variations in executive functioning predict concurrent success in schooling, relationships, and behavior, as well as important life outcomes years later. Such findings may suggest that certain individuals are destined for good executive functioning and success. However, environmental influences on executive function and development have long been recognized. Recent research in this tradition demonstrates the power of social contextual influences on children's engagement of executive functions. Such findings suggest new interpretations of why individuals differ in executive functioning and associated life outcomes, including across cultures and socioeconomic statuses. These findings raise fundamental questions about how best to conceptualize, measure, and support executive functioning across diverse contexts. Future research addressing real-world dynamics and computational mechanisms will elucidate how executive functioning emerges in the world.

Objects permeate human culture and saturate the imagination. This duality offers both opportunity and challenge. Here we ask how young human children learn to exploit the immense potential afforded by objects that can exist simultaneously in physical and imaginary realms. To this end, we advance a new framework that integrates the presently siloed literatures on manual skill and play development. We argue that developments in children's real and imagined use of objects are embodied, reciprocal, and intertwined. Advances in one plane of action influence and scaffold advances in the other. Consistent with this unified framework, we show how real and imagined interactions with objects are characterized by developmental parallels in how children (a) transcend the present to encompass future points in time and space, (b) extend beyond the self, and (c) gradually move beyond objects’ designed functions. In addition, we highlight bidirectional influences in children's real and imagined interactions with objects: Play engenders practice and skill in using objects, but just the same, practice using objects engenders advances in play. We close by highlighting the theoretical, empirical, and translational implications of this embodied and integrated account of manual skill and play development.

We describe the promise of the Fragile Families and Child Wellbeing Study (FFCWS) for developmental researchers. FFCWS is a birth cohort study of 4,898 children born in 1998–2000 in large US cities. This prospective national study collected data on children and parents at birth and during infancy (age 1), toddlerhood (age 3), early childhood (age 5), middle childhood (age 9), adolescence (age 15), and, in progress, young adulthood (age 22). Though FFCWS was created to understand the lives of unmarried parent families, its comprehensive data on parents, children, and contexts can be used to explore many other developmental questions. We identify six opportunities for developmentalists: (a) analyzing developmental trajectories, (b) identifying the importance of the timing of exposures for later development, (c) documenting bidirectional influences on development, (d) understanding development in context, (e) identifying biological moderators and mechanisms, and (f) using an urban-born cohort that is large, diverse, and prospective.

Childhood obesity is a multifactorial disease, shaped by child, familial, and societal influences; prevention efforts must begin early in childhood. Viewing the problem of childhood obesity through a developmental lens is critical to understanding the nuances of a child's interactions with food and their environment across the span of growth and development. Risk factors for childhood obesity begin prior to birth, compounding across the life course. Some significant risk factors are unmodifiable (e.g., genetics) while others are theoretically modifiable. Social inequities, however, hinder many families from easily making modifications to a range of risk factors. The objective of this review is to provide background and an overview of the literature on childhood obesity in early childhood (birth to 5 years of age) in a developmental context. Special focus is placed on unique developmental considerations, child eating behaviors, and parental feeding behaviors in infancy, toddlerhood, and preschool ages.

Asthma is the most common disorder in childhood, affecting six million children in the United States. Asthma is a heterogeneous disease, but most cases either start in early life or have their roots in events occurring in utero or during the preschool years. Protective or harmful exposures, including to environmental microbes, occurring during critical developmental windows determine patterns of immune responses that often persist for a lifetime. Air pollution, tobacco smoke, and prematurity can cause congenital airway narrowing, and newborns with decreased airway function are at risk for having asthma symptoms up to adulthood. Effects of environmental exposures are modified by common genetic variations and may also be mediated by prenatal changes in the epigenetic structure of the genome. Based on this evidence, we have postulated that asthma should be considered a developmental disorder, and this concept may be applicable to other chronic medical conditions affecting both children and adults.

Developmental cognitive neuroscience is being pulled in new directions by network science and big data. Brain imaging [e.g., functional magnetic resonance imaging (fMRI), functional connectivity MRI], analytical advances (e.g., graph theory, machine learning), and access to large computing resources have empowered us to collect and process neurobehavioral datafaster and in larger populations than ever before. The translational potential from these advances is unparalleled, as a better understanding of complex human brain functions is best grounded in the onset of these functions during human development. However, the maturation of developmental cognitive neuroscience has seen the emergence of new challenges and pitfalls, which have significantly slowed progress and need to be overcome to maintain momentum. In this review, we examine the state of developmental cognitive neuroscience in the era of networks and big data. In addition, we provide a discussion of the strengths, weaknesses, opportunities, and threats (SWOT) of the field to advance developmental cognitive neuroscience's scientific and translational potential.
