"Popular examines why popularity plays such a key role in our development and, ultimately, how it still influences our happiness and success today. In many ways -- some even beyond our conscious awareness -- those old dynamics of our youth continue to play out in every business meeting, every social gathering, in our personal relationships, and even how we raise our children. Our popularity even affects our DNA, our health, and our mortality in fascinating ways we never previously realized. More than childhood intelligence, family background, or prior psychological issues, research indicates that it's how popular we were in our early years that predicts how successful and how happy we grow up to be. But it's not always the conventionally popular people who fare the best, for the simple reason that there is more than one type of popularity -- and many of us still long for the wrong one. As children, we strive to be likable, which can offer real benefits not only on the playground but throughout our lives. In adolescence, though, a new form of popularity emerges, and we suddenly begin to care about status, power, influence, and notoriety -- research indicates that this type of popularity hurts us more than we realize. Realistically, we can't ignore our natural human social impulses to be included and well-regarded by others, but we can learn how to manage those impulses in beneficial and gratifying ways."--Amazon.com

This article reviews empirical and theoretical contributions to a multidisciplinary understanding of peer influence processes in adolescence over the past decade. Five themes of peer influence research from this decade were identified, including a broadening of the range of behaviors for which peer influence occurs, distinguishing the sources of influence, probing the conditions under which influence is amplified/attenuated (moderators), testing theoretically based models of peer influence processes (mechanisms), and preliminary exploration of behavioral neuroscience perspectives on peer influence. This review highlights advances in each of these areas, underscores gaps in current knowledge of peer influence processes, and outlines important challenges for future research.

The period of adolescence involves growth, adaptation, and dramatic reorganization in almost every aspect of social and psychological development. The Encyclopedia of Adolescence offers an exhaustive and comprehensive review of current theory and research findings pertaining to this critical decade of life. Leading scientists offer accessible and easily readable reviews of biological, social, educational, occupational, and cultural factors that shape adolescent development. Issues in normative development, individual differences, and psychopathology/maladjustment are reviewed. Over 130 chapte

Concurrent and longitudinal associations between peer crowd affiliation and internalized distress were examined in a sample of 246 youth (148 girls, 98 boys). Children completed measures of depression, social anxiety, loneliness, and self‐esteem when they were in grades 4 to 6 (Time 1), and again 6 years later during adolescence (grades 10 – 12; Time 2). At Time 2, adolescents also reported their self‐concept and their identification with reputation‐based peer crowds, including Populars, Jocks, Brains, Burnouts, Non‐Conformists, and None/Average crowds. Results indicated that adolescents' report of peer crowd affiliation was concurrently associated with self‐concept and levels of internalizing distress. Follow‐back analyses of internalizing trajectories revealed that Populars/Jocks had experienced significant declines in internalizing distress across development, whereas Brains exhibited some increases in internalizing distress between childhood and adolescence.

This study investigated longitudinal associations between adolescents' technology‐based communication and the development of interpersonal competencies within romantic relationships. A school‐based sample of 487 adolescents (58% girls; Mage = 14.1) participated at two time points, one year apart. Participants reported (1) proportions of daily communication with romantic partners via traditional modes (in person, on the phone) versus technological modes (text messaging, social networking sites) and (2) competence in the romantic relationship skill domains of negative assertion and conflict management. Results of cross‐lagged panel models indicated that adolescents who engaged in greater proportions of technology‐based communication with romantic partners reported lower levels of interpersonal competencies one year later, but not vice versa; associations were particularly strong for boys.

Suicide is the second leading cause of death for adolescents in the United States, yet remarkably little is known regarding risk factors for suicidal thoughts and behaviors (STBs), relatively few federal grants and scientific publications focus on STBs, and few evidence‐based approaches to prevent or treat STBs are available. This "decade in review" article discusses five domains of recent empirical findings that span biological, environmental, and contextual systems and can guide future research in this high priority area: (1) the role of the central nervous system; (2) physiological risk factors, including the peripheral nervous system; (3) proximal acute stress responses; (4) novel behavioral and psychological risk factors; and (5) broader societal factors impacting diverse populations and several additional nascent areas worthy of further investigation.

AbstractRecent mechanistic models of cognitive control define the normative level of control deployment as a function of the effort cost of exerting control balanced against the reward that can be attained by exerting control. Despite these models explaining empirical findings in adults, prior literature has suggested that adolescents may not adaptively integrate value into estimates of how much cognitive control they should deploy. Moreover, much work in adolescent neurodevelopment casts social valuation processes as competing with, and in many cases overwhelming, cognitive control in adolescence. Here, we test whether social incentives can adaptively increase cognitive control. Adolescents (Mage = 14.64, 44 male, N = 87) completed an incentivized cognitive control task in which they could exert cognitive control to receive rewards on behalf of real peers who were rated by all peers in their school grade as being of either high‐ or low‐status. Using Bayesian modeling, we find robust evidence that adolescents exert more cognitive control for high‐ relative to low‐status peers. Moreover, we demonstrate that social incentives, irrespective of their high‐ or low‐status, boost adolescent cognitive control above baseline control where no incentives are offered. Findings support the hypothesis that the cognitive control system in early adolescence is flexibly modulated by social value.

AbstractThis study examined linear and curvilinear longitudinal associations between peer status (i.e., likeability and popularity) and socioevaluative concern, a socio‐cognitive feature characterized by attunement to judgment from peers. A sample of 716 adolescents (Mage = 16.01, SD = 1.25; 54% female; 46.5% White; 69.5% reduced‐price lunch) was assessed twice annually. Likeability and popularity were assessed with peer nominations at Time 1. Measures of general (rejection sensitivity, peer importance) and online (digital status seeking, online status importance) socioevaluative concern were obtained at Times 1 and 2. High and low levels of likeability were longitudinally associated with increased peer importance, while high and low levels of popularity were associated with increased digital status seeking, and decreased online status importance for girls.

AbstractFor 14 days three times per day (6072 observations), adolescents (N = 207, Mage = 15.45 years) reported their digital (i.e., video chatting, texting, social media, and phone calling) communication with peers and their social connectedness. Controlling for in‐person interactions, adolescents felt more connected in hours when they had communicated with peers by video chatting, texting, or social media, but not phone calling. Girls communicated with peers via text and social media more than boys, and boys talked on the phone more than girls. Boys who talked, texted, or video chatted more on average reported higher connectedness on average, whereas girls did not. As the links with connectedness were only found at the hourly‐ and not the daily level, results highlight that a sense of connectedness from digital media may be fleeting in nature.
