Extreme and chronic adverse experiences in childhood are linked to disruptions in a wide range of behavioral processes, including self-regulation, increased risk taking, and impulsivity. One proposed mechanism for these effects is alterations in how children learn and use information about rewards and risk in their environment. This type of decision making is a complex and multifaceted process consisting of distinct subcomponents, each of which may have varying effects on behavior. Here, we conducted a systematic review of the literature examining how reward and risk related decision making is influenced by childhood adversity. We aimed to identify whether childhood adversity is associated with alterations in how children learn about value information and how they subsequently use that information to inform decisions. Results suggest adverse experiences in childhood primarily impacts how individuals prioritize avoidance of risk and leads to devaluation of rewards.

Human's abilities to reason about what others may be feeling undergo prolonged development throughout childhood and adolescence, yet the mechanisms driving the emergence of these skills remain elusive. This set of studies, conducted within the same sample of 5- to 10-year-old children, examines how spontaneous perceptual discrimination of facial configurations and activation of conceptual knowledge about emotions become integrated across development. Perceptual discrimination is measured using an EEG frequency tagging paradigm (Study 1). Conceptual knowledge is evaluated with a conceptual similarity rating task (Study 2). Two behavioral tasks (sorting and matching) are employed to assess emotion understanding (Study 3). Representational similarity analysis assesses the predictive effects of perceptual discrimination and conceptual knowledge on children's behavioral judgments. Here we show that while the ability to discriminate stereotypical facial configurations emerges by preschool age, its influence diminishes with age. In contrast, children's inferences about other people's emotions come to rely more on conceptual knowledge with increasing age (and, presumably, social experience).

There are numerous popular books, magazines, blogs, and websites that provide advice or anecdotes about how best to care for children. These sources of information can drown out conclusions based on scientific consensus, negatively influencing the behavior of parents and other caregivers and impacting societal action and policies implemented to support children and families. Scientific research in child development, psychology, and neuroscience provides valuable insights into key aspects of caring for children that not only can enhance the likelihood of positive outcomes for children but can also empower parents, childcare providers, and communities with the knowledge and confidence needed to make informed decisions about their childrens upbringing. These data can also inform public policies that can increase access and reduce barriers to quality environments for all children. Here, we highlight reliable findings about biobehavioral development that can bear upon policies and practices for supporting healthy child development.

Adverse early life experiences, such as child maltreatment, shapes hypothalamic-pituitary-adrenal (HPA) activity. The impact of social context is often probed through laboratory stress reactivity, yet child maltreatment is a severe form of chronic stress that recalibrates even stable or relatively inflexible stress systems such as cortisol's diurnal rhythm. This study was designed to determine how different social contexts, which place divergent demands on children, shape cortisol's diurnal rhythm. Participants include 120 adolescents (9-14 years), including 42 youth with substantiated child physical abuse. Up to 32 saliva samples were obtained in the laboratory, on days youth stayed home, and on school days. A 3-level hierarchical linear model examined cortisol within each day and extracted the diurnal rhythm at level 1; across days at level 2; and between-individual differences in cortisol and its rhythm at level 3. While cortisol's diurnal rhythm was flattened when youth were in the novel laboratory context, the impact of maltreatment was observed within the home context such that maltreated children had persistently flattened diurnal rhythms. The effect of maltreatment overlapped with current chronic interpersonal family stress. Results are consistent with the idea that maltreatment exerts a robust, detrimental impact on the HPA axis and are interpreted in the context of less flexibility and rhythmicity. The HPA axis adapts by encoding signifiers of relevant harsh or unpredictable environments, and the extreme stress of physical abuse in the family setting may be one of these environments which calibrates the developing child's stress responsive system, even throughout a developmental stage in which the family takes on diminishing importance.

Computational models of development have the potential to address a key challenge in emotional development research: investigating not only what changes across development but also how these changes come about. Drawing on connectionist and Bayesian methods, this review considers how computational modeling could augment the processes of theorizing and behavioral research to investigate causal processes underlying emotional development. As an illustrative example, we consider how different modeling approaches could help researchers evaluate different ideas about how children come to reason about others' emotions in increasingly sophisticated ways across development. This example is just a starting point; we propose that computational modeling could be an invaluable tool for exploring a variety of yet unresolved "how" questions in emotional development.

Childhood maltreatment may adversely affect brain development and consequently influence behavioral, emotional, and psychological patterns during adulthood. In this study, we propose an analytical pipeline for modeling the altered topological structure of brain white matter in maltreated and typically developing children. We perform topological data analysis (TDA) to assess the alteration in the global topology of the brain white-matter structural covariance network among children. We use persistent homology, an algebraic technique in TDA, to analyze topological features in the brain covariance networks constructed from structural magnetic resonance imaging (MRI) and diffusion tensor imaging (DTI). We develop a novel framework for statistical inference based on the Wasserstein distance to assess the significance of the observed topological differences. Using these methods in comparing maltreated children to a typically developing control group, we find that maltreatment may increase homogeneity in white matter structures and thus induce higher correlations in the structural covariance; this is reflected in the topological profile. Our findings strongly suggest that TDA can be a valuable framework to model altered topological structures of the brain.

A critical component of human learning reflects the balance people must achieve between focusing on the utility of what they know versus openness to what they have yet to experience. How individuals decide whether to explore new options versus exploit known options has garnered growing interest in recent years. Yet, the component processes underlying decisions to explore and whether these processes change across development remain poorly understood. By contrasting a variety of tasks that measure exploration in slightly different ways, we found that decisions about whether to explore reflect (a) random exploration that is not explicitly goal-directed and (b) directed exploration to purposefully reduce uncertainty. While these components similarly characterized the decision-making of both youth and adults, younger participants made decisions that were less strategic, but more exploratory and flexible, than those of adults. These findings are discussed in terms of how people adapt to and learn from changing environments over time.Data has been made available in the Open Science Foundation platform (osf.io).

The ability to infer others' emotions is important for social communication. This study examines three key aspects of emotion perception for which relatively little is currently known: (1) the evaluation of the intensity of portrayed emotion, (2) the role of contextual information in the perception of facial configurations, and (3) developmental differences in how children perceive co-occurring facial and contextual information. Two experiments examined developmental effects on the influence of congruent, incongruent, and neutral situational contexts on participants' reasoning about others' emotions, both with and without emotion labels. Experiment 1 revealed that participants interpreted others' emotions to be of higher intensity when facial movements were congruent with contextual information. This effect was greater for children compared to adolescents and adults. Experiment 2 showed that without verbal emotion category labels, adults relied less on context to scale their intensity judgments, but children showed an opposite pattern; in the absence of labels, children relied more on contextual information than facial information. Making accurate inferences about others' internal states is a complex learning task given high variability within and across individuals and contexts. These data suggest changes in attention to perceptual information as such learning occurs.

The idea of arousal as a non-specific state of activation has been implicated as an explanatory factor for many aspects of human behavior, ranging from emotional experiences to learning and memory. Critiques of this concept have highlighted that arousal is ambiguous and evidence for its role in emotion is mixed. However, contemporary emotion theories and empirical research continue to incorporate the concept of arousal in ways that fail to address its problems. Here, we review the origins of the term arousal in physiology and trace how it has been translated and applied to psychology (particularly as it relates to emotion). We consider whether the construct of arousal is currently (a) consistent and (b) useful in understanding human behavior.

The field of developmental psychopathology has grown broadly. Here, I draw upon lessons learned from Dante Cicchetti to highlight areas that show promise for continued disciplinary advancement. These include attention to equifinality and multifinality in the conceptualization of initial study designs, and more emphasis on specificity in accounting for developmental change. A shift from reliance on external events and towards greater diversity of research approaches will allow researchers to devote attention to the variety of ways that individuals come to understand and then respond to their own life experiences. The field of developmental psychopathology holds tremendous promise for advancing basic science about human development that can be applied to create interventions that improve the well-being of individuals and address significant societal issues.

Early in development, the process of exploration helps children gather new information that fosters learning about the world. Yet, it is unclear how childhood experiences may influence the way humans approach new learning. What influences decisions to exploit known, familiar options versus trying a novel alternative? We found that childhood unpredictability, characterized by unpredictable caregiving and unstable living environments, was associated with reduced exploratory behavior. This effect holds while controlling for individual differences, including anxiety and stress. Individuals who perceived their childhoods as unpredictable explored less and were instead more likely to repeat previous choices (habitual responding). They were also more sensitive to uncertainty than to potential rewards, even when the familiar options yielded lower rewards. We examined these effects across multiple task contexts and via both in-person (N = 78) and online replication (N = 84) studies among 10- to 13-y-olds. Results are discussed in terms of the potential cascading effects of unpredictable environments on the development of decision-making and the effects of early experience on subsequent learning.

This article reviews research on the development of emotion regulation in adolescence. The role of biological, social learning, and other environmental factors such as the family environment set the stage for the development of emotion regulation processes in childhood. Adolescence is a time of increasing stress, making emotion regulation particularly challenging. We review how brain development, puberty, stress, and the peer context may contribute to difficulty in effectively regulating emotion during this developmental period. Finally, we discuss some of the more common forms of emotion dysregulation in adolescence. Throughout this article, we consider impacts of contextual factors such as the Covid-19 pandemic, stigma, and structural racism on these processes.

Learners flexibly update category boundaries to adjust to the range of experiences they encounter. However, little is known about whether the degree of flexibility is consistent across domains. We examined whether categorization of social input, specifically emotions, is afforded more flexibility as compared to other biological input. To address this question, children (6–12 years; 32 female, 37 male; 7 Hispanic or Latino, 62 not Hispanic or Latino; 8 Black or African American, 14 multiracial, 46 White, 1 selected “other”) categorized faces morphed from calm to upset and animals morphed from a horse to a cow across task phases that differed in the distribution of stimuli presented. Learners flexibly adjusted both emotion and animal category boundaries according to distributional information, yet children showed more flexibility when updating their category boundaries for emotions. These results provide support for the idea that children—who must adjust to the vast and varied emotional signals of their social partners—respond to social signals dynamically in order to make predictions about the internal states and future behaviors of others.

Stressful experiences in armed conflict incur intergenerational effects through parental behaviors with their children. A recent study reported that among Syrian refugee families, mothers’ (but not fathers’) post-traumatic stress (PTS) impacted children’s emotional processing. In this study, we aim to shed further light on this phenomenon by analyzing how the parenting practices in the context of post-traumatic stress confers protection or risk for children’s emotional processing. Participants were 6–18-year-old children (n = 212) and their mothers (n = 94), who fled from Syria and were residing in Turkish communities. We used the computer-based emotional processing task including photos of facial movements typically associated with different emotions to measure children’s capacity for emotional processing. Mothers reported their PTS and the discipline types they use, as well as the contextual factors related to their refugee background. Linear mixed effect models were constructed first, to find out the discipline types that are most strongly associated with emotional processing of the child, and second, to examine whether these discipline types moderate the effect of maternal PTS on children's emotional processing. Finally, generalized linear models were constructed to examine which contextual factors are associated with the use of these discipline types by mothers. We found that spanking as a discipline type was associated with poorer child emotional processing, whereas withholding of media access was associated with better emotional processing. Younger and less religious mothers were more prone to use spanking. The study underlines the need for parenting programs alongside with efforts to address mental health issues among mothers living under armed conflict.

Childhood adversity is a major risk factor for multiple forms of psychopathology, and recent efforts have focused on understanding the underlying psychological mechanisms. One outstanding candidate is emotion regulation, which has been associated with both childhood adversity, and psychopathology. Based on the available evidence, the present meta-analysis set out to investigate the mechanistic involvement of emotion regulation in the relation between childhood adversity and psychopathology. Systematic searches in three databases (PubMed; PsycINFO; Web of Science) identified 215 eligible studies. Using meta-analytic structural equation modeling, we fitted a partial mediation model to the available data across studies, in which childhood adversity was related to psychopathology both directly and through emotion regulation. Multiple emotion regulation dimensions were analyzed, including emotion regulation difficulties and the habitual use of rumination, distraction, reappraisal, and suppression. Measures of psychopathology included a wide range of internalizing and externalizing symptoms in both clinical and non-clinical samples. The results indicated that childhood adversity was positively associated with emotion regulation difficulties, as well as with the habitual use of rumination and suppression. In turn, these measures of emotion regulation were positively associated with psychopathology. Habitual reappraisal use showed negative relations with both childhood adversity and psychopathology. All these emotion regulation measures were supported as mediators in the relation between childhood adversity and psychopathology. In contrast, distraction was not related to childhood adversity or psychopathology, and its mediator role was not supported. These results suggest that altered emotion regulation is a consistent marker of childhood adversity and contributes to risk of psychopathology.

Loneliness, or perceived social isolation, is linked to a number of negative long-term effects on both mental and physical health. However, how an individual responds to feeling lonely may influence their risk for later negative health outcomes. Here, we sought to clarify what influences variability in individuals' motivated responses to loneliness. Specifically, we assessed whether resting parasympathetic activity, a physiological marker linked to flexible adaptation, facilitates increased approach-oriented behaviors. Seventy-four adult participants underwent a conditioning paradigm assessing how they approach and avoid rewards and threats. Individuals with higher levels of loneliness and high resting parasympathetic activity were more likely to demonstrate approach behaviors. We discuss these findings in terms of the role resting parasympathetic activity may play in facilitating adaptive responses to feeling socially isolated.

To effectively navigate their environments, infants and children learn how to recognize events predict salient outcomes, such as rewards or punishments. Relatively little is known about how children acquire this ability to attach value to the stimuli they encounter. Studies often examine children's ability to learn about rewards and threats using either classical conditioning or behavioral choice paradigms. Here, we assess both approaches and find that they yield different outcomes in terms of which individuals had efficiently learned the value of information presented to them. The findings offer new insights into understanding how to assess different facets of value learning in children.
