“Using digital media or sleeping … that is the question”. A meta-analysis on digital media use and unhealthy sleep in adolescence

This systematic review with meta-analysis aims to examine the relation between different aspects of digital media use and sleep health patterns. Eligible studies had to be longitudinal and with adolescents' sample. Multiple search strategies were applied until January 28, 2023 in order to identify relevant research published in peer-reviewed journal articles or available grey literature. A final set of 23 studies (N = 116,431; 53.2% female; Mage at baseline = 13.4 years) were included. The quality of the studies, assessed with an adapted version of the Newcastle-Ottawa Scale, was high with a consequent low risk of bias. Meta-analytic results showed that tradi-tional media use (r =-0.33 [-0.44;-0.22]), social media use (r =-0.12 [-0.22;-0.01]), prolonged use (r = -0.06 [-0.11;-0.01]), and dysfunctional use (r =-0.19 [-0.29;-0.09]) are negatively related to adolescents' sleep health at a later time point. Conversely, sleep patterns were not related to social media use (r =-.05 [-0.10; 0.00]) and utilization time (r =-0.13 [-0.30; 0.04]), but they were related to dysfunctional use of media (r = -0.22 [-0.33; -0.10]). Overall, this review highlights the presence of a vicious cycle between digital media use and sleep health in adolescence

Editorial: Youth personality development

The period between childhood and adulthood is a turbulent time of life (Hollenstein & Lougheed, 2013). While there is a solid body of research on youth social, biological, and psychological development (Sawyer et al., 2018; Steinberg & Morris, 2001), surprisingly little is known about personality processes and individual differences in them during these years. The papers in this Special Issue make important contributions to the current literature in three ways: first, by mapping developmental patterns to broader conceptualizations of personality, including personality pathology, second, by examining predictors and mechanisms in youth personality development, and third, by linking youth personality development to later life outcomes. We hope that the results of these papers will contribute to a more nuanced understanding of adolescent personality development in diverse cultural contexts and stimulate new integrative research

Identities: A developmental social-psychological perspective

In this contribution, we review research that uses a cross-fertilisation approach to integrate developmental and social-psychological perspectives on how identities are formed and changed over time and how identity processes are genuinely social, being embedded in social contexts and fed by social contents. First, we outline the three-factor identity model as a parsimonious approach to understanding the dynamics of identity development. Second, we review empirical studies with longitudinal approaches to shed light on how identity processes are embedded in key contexts such as family, friendships and society at large through behaviours such as civic engagement. Third, we discuss the interplay between personal and social identities. We conclude by highlighting how adopting a cross-fertilisation approach that combines social-psychological and developmental perspective can significantly advance the theoretical understanding of identity dynamics. Finally, we address similarities and differences between personal identity and social identity approaches, and we provide an agenda for future research

Like parents, like children... this is not always the case! A longitudinal study on the family transmission of intergroup contact

During adolescence, opportunities for interethnic interactions can shape future attitudes toward diversity. However, it is unclear how family can influence adolescents' quality of contact in different life contexts. This study aims to fill this gap. A sample of 702 Italian adolescents (M-age=15.61, SDage=1.11, 48.58% girls) and their parents (615 mothers, M-age=48.45, SDage=4.34; 487 fathers, M-age=51.22, SDage=4.92) completed questionnaires at two time points. Cross-lagged models indicated that adolescents' intergroup contact at T1 was associated with mothers' contact over time, mainly in structured (i.e., school and work) contexts. No significant associations were found regarding fathers' intergroup contact and unstructured contexts. These results shed new light on the process of family transmission during adolescence, particularly regarding intergroup dynamics

Development of prejudice against immigrants and ethnic minorities in adolescence: A systematic review with meta-analysis of longitudinal studies

Previous research highlighted that prejudice is already formed in early childhood, reaches a peak in middle childhood, and slightly decreases in late childhood, whereas the development of prejudice in adolescence was mostly unknown. This systematic review with meta-analysis aimed to comprehensively summarize and integrate prior longitudinal research on adolescents’ prejudice to address two main research questions: (a) how does prejudice develop in adolescence? (b) which factors are related to holding prejudicial attitudes in adolescence? Using multiple search strategies and applying a two-step selection process, a final set of 26 journal articles including a total of 30 samples (N = 23,513 participants) was found to match eligibility criteria and, thus, was included in the review. The meta-analytic findings highlighted that (a) prejudice does not change in adolescence; (b) interindividual differences in prejudice are well-established, they become increasingly strong with age, and they are inversely related to the time-lag between assessments; and (c) several individual, identity, and contextual factors are related to prejudice in different ways. More specifically, social dominance orientation, intergroup anxiety, identification with the national ingroup, and parental prejudice contributed to increasing later levels of adolescents’ prejudice, whereas intergroup friendship contributed to lessening it. Importantly, prejudice had comparable reverse effects on these factors, pointing to consistent bidirectional associations. These main findings are discussed considering their implications for future research and practice

A Data-Driven Slip Estimation Approach for Effective Braking Control under Varying Road Conditions

The performances of braking control systems for robotic platforms, e.g., assisted and autonomous vehicles, airplanes and drones, are deeply influenced by the road-tire friction experienced during the maneuver. Therefore, the availability of accurate estimation algorithms is of major importance in the development of advanced control schemes. The focus of this paper is on the estimation problem. In particular, a novel estimation algorithm is proposed, based on a multi-layer neural network. The training is based on a synthetic data set, derived from a widely used friction model. The open loop performances of the proposed algorithm are evaluated in a number of simulated scenarios. Moreover, different control schemes are used to test the closed loop scenario, where the estimated optimal slip is used as the set-point. The experimental results and the comparison with a model based baseline show that the proposed approach can provide an effective best slip estimation

The Ginevra de\u2019 Benci Effect: Competence, Morality, and Attractiveness Inferred From Faces Predict Hiring Decisions for Women

The present study examined the role of morality, competence, and attractiveness as perceived from faces in predicting hiring decisions for men and women. Results showed that for both female and male applicants, facial competence significantly predicted the hiring decision directly and indirectly, through the mediation of the overall impression. Decisions concerning female applicants were, however, significantly predicted by multiple dimensions\u2014that is, facial morality, facial competence, and attractiveness\u2014with the mediation of the overall impression. Facial competence was the only significant predictor of impression and, in turn, hiring decision about men. These findings resonate the motto Virtutem forma decorat, \u201cBeauty adorns virtue,\u201d painted by Leonardo da Vinci on the reverse side of the portrait of Ginevra de\u2019 Benci, and suggest that women\u2019s chances of getting a job are less than those of men whenever they do not show a moral and competent and attractive face
