In recent years, an increased interest in the importance of children's ability to regulate emotions in socially adaptive ways has driven considerable research on the development of emotion regulation. A widely studied emotion regulation strategy known as expressive suppression (ES), in which a person attempts to conceal emotion-expressive behavior, has been the focus of several recent studies of child and adolescent emotion regulation. Like much of the literature on children's emotion regulation strategies in general, this literature lacks a theoretical framework for organizing the findings, understanding their implications, and guiding future research (Cole, Martin, & Dennis, 2004). In the present review, we integrate theory and data on ES in childhood and adolescence using the process model of emotion regulation (Gross, 2015), a framework that is widely used in research with adults, to organize and interpret the findings. Specifically, the process model is used to understand what factors contribute to children's use of ES in a given context and when and why ES might be associated with negative emotional, social, cognitive, and physiological costs. We conclude by outlining an agenda for future research, noting major gaps in current knowledge, offering novel ways of thinking about ES in childhood, and highlighting new directions for moving the field forward. Research illuminating the developmental course and correlates of expressive suppression in early life can contribute to a deeper understanding of this emotion regulation strategy and can inform intervention efforts to improve outcomes across the life span.

Prosocial behavior involves attempting to improve others' welfare and plays a central role in cooperative social relationships. Among the manifold processes that contribute to prosocial development is the quality of children's attachment to their caregivers. Often, researchers have investigated the link between secure attachment and broad indices of prosociality. Recent theory and research, however, suggest that children's prosocial behavior is multifaceted, with distinct correlates and developmental trajectories characterizing specific prosocial behaviors. We offer a theoretical model of the role of parent-child attachment in the development of prosocial behavior, first broadly, and then with regard to comforting, sharing, and helping, specifically.Further, we review the empirical work on this topic from infancy through adolescence. Overall, evidence supports an association between secure attachment and prosociality, broadly defined, but results vary across comforting, sharing, and helping. We discuss potential explanations for the findings and outline directions for future research examining the role of attachment in shaping the diversity of prosocial behaviors across development.attachment, emotion regulation, empathy, prosocial behavior, social competence 1 | I NTR OD U CTI ON Prosocial behavior involves voluntary action to improve another's welfare; it encompasses diverse behaviors, such as feeding a hungry child, lending a hand to a stranger, or soothing a distraught friend. Individual differences in prosociality emerge early in life and carry significant implications for social development (e.g., Eisenberg, Fabes, & Spinrad, 2006). Given the importance of prosociality in sustaining cooperative human relationships, substantial research has focused on understanding the factors that contribute to its development.

Although evidence shows that attachment insecurity and disorganization increase risk for the development of psychopathology (Fearon, Bakermans-Kranenburg, van IJzendoorn, Lapsley, & Roisman, 2010; Groh, Roisman, van IJzendoorn, Bakermans-Kranenburg, & Fearon, 2012), implementation challenges have precluded dissemination of attachment interventions on the broad scale at which they are needed. The Circle of Security–Parenting Intervention (COS-P; Cooper, Hoffman, & Powell, 2009), designed with broad implementation in mind, addresses this gap by training community service providers to use a manualized, video-based program to help caregivers provide a secure base and a safe haven for their children. The present study is a randomized controlled trial of COS-P in a low-income sample of Head Start enrolled children and their mothers. Mothers (N = 141; 75 intervention, 66 waitlist control) completed a baseline assessment and returned with their children after the 10-week intervention for the outcome assessment, which included the Strange Situation. Intent to treat analyses revealed a main effect for maternal response to child distress, with mothers assigned to COS-P reporting fewer unsupportive (but not more supportive) responses to distress than control group mothers, and a main effect for one dimension of child executive functioning (inhibitory control but not cognitive flexibility when maternal age and marital status were controlled), with intervention group children showing greater control. There were, however, no main effects of intervention for child attachment or behavior problems. Exploratory follow-up analyses suggested intervention effects were moderated by maternal attachment style or depressive symptoms, with moderated intervention effects emerging for child attachment security and disorganization, but not avoidance; for inhibitory control but not cognitive flexibility; and for child internalizing but not externalizing behavior problems. This initial randomized controlled trial of the efficacy of COS-P sets the stage for further exploration of “what works for whom” in attachment intervention.

Based on attachment theory and decades of research on attachment processes and relationships, this chapter shows that attachment security, experienced in relationships with sensitive and responsive parents and partners across the life span, fosters positive attitudes toward both self and others, and also provides a foundation for desirable psychological states discussed in the Buddhist literature: mindfulness, self-compassion, and nonattachment. We review research involving children, adolescents, and adults showing that the major forms of attachment insecurity—anxiety and avoidance—interfere with healthy self-approval and self-acceptance, and also with kindness and generosity toward others. Self-acceptance and self-compassion are not “egoistic” in the negative sense; far from being psychologically and social destructive, they are foundations of openness and kindness toward others. The usual origin of attachment-related security is supportive relationships in childhood, but security can also be increased by later relationships and by laboratory and clinical interventions.

The first months after becoming a new parent are a unique and important period in human development. Despite substantial research on the many social and biological changes that occur during the first months of parenthood, little is known about changes in mothers' attachment. The present study examines developmental stability and change in first-time mothers' attachment style across the first 2 years of motherhood. At Time 1, 162 economically stressed primiparous mothers (Mage = 23.98 years, SD = 5.18) completed measures of attachment anxiety and avoidance at five time points: when their children were 0, 6, 12, 18, and 24 months of age. Converging results of stability functions and latent growth curve models suggest that attachment styles were generally stable during the first 2 years of motherhood, even in this economically stressed sample. Furthermore, model comparisons revealed that a prototype model better characterized the developmental dynamics of mothers' attachment style than did a revisionist model, consistent with previous studies of adults and adolescents. This suggests that a relatively enduring prototype underlies mothers' attachment style and anchors the extent to which mothers experience attachment-related changes following the birth of their first child. Within this overall picture of continuity, however, some mothers did show change over time, and specific factors emerged as moderators of attachment stability, including maternal depressive symptoms and overall psychological distress, as well as sensitive care from their own mothers. Findings shed light on patterns of continuity and change in new parents' development. (PsycINFO Database Record
