Susceptibility to prosocial and antisocial influence in adolescence

Adolescents Are More Utilitarian Than Adults in Group Moral Decision-Making

This study explores how peers influence the moral decisions of Chinese adolescents (12- to 16-year-olds, M age = 14.32, n = 84) and young adults (18- to 26-year-olds, M age = 20.92, n = 99) in moral dilemmas. Participants were asked to make moral decisions individually and then collectively within groups of three to reach a consensus in Trolly dilemma and Footbridge dilemma. They were also required to evaluate the degree to which they felt their decisions were moral. Results showed that adolescents tended to choose "action" (pull the lever in Trolly dilemma, or push the man in Footbridge dilemma) more than adults, and evaluate their "no action" choice as more immoral than young adults across both individual and group settings. Adolescents showed consistent decision-making patterns regardless of whether decisions were made individually or collectively, while adults were more likely to choose "no action" in group decision-making. Our results suggest that adolescents are more utilitarian than young adults when making decisions in moral dilemmas, compared to young adults. Young adults are less likely to make utilitarian choices when they are in groups than when they make decisions individually.

Investigation of the mental health and cognitive correlates of psychological decentering in adolescence

The ability to notice and reflect on distressing internal experiences from an objective perspective, often called psychological decentering, has been posited to be protective against mental health difficulties. However, little is known about how this skill relates to age across adolescence, its relationship with mental health, and how it may impact key domains such as affective executive control and social cognition. This study analysed a pre-existing dataset including mental health measures and cognitive tasks, administered to adolescents in Greater London and Cambridge (mean age (SD) = 14.4 (1.77) years, N = 553). A self-report index of decentering based on available questionnaire items in the dataset was developed. Multiple linear regression was used to examine associations between decentering and mental health, affective executive control (measured using an affective Stroop Task, affective Working Memory Task, and affective Sustained Attention to Response Task) and social cognition. Higher decentering was significantly associated with lower depression and anxiety scores and higher psychological wellbeing. Results did not indicate significant relationships between decentering, affective executive control and social cognition. Further research is needed to discover cognitive mechanisms associated with this process, which could allow for optimisation of existing psychological therapy and reveal new avenues of intervention.

Mental health and socio-cognitive predictors of adherence to COVID-19 social distancing rules in adolescents in England

The COVID-19 pandemic prompted governments worldwide to introduce social distancing measures, including school closures and restrictions on in-person socialising. However, adherence to social distancing was challenging for many - particularly adolescents, for whom social interaction is crucial for development. The current study aimed to identify individual-level influences on adherence to social distancing in a longitudinal sample of adolescents aged 11-20 years in England, who took part in a randomised controlled trial. At baseline, 460 participants completed detailed pre-pandemic assessments, including mental health and well-being, altruism, delayed reward discounting, rejection sensitivity, prosociality and susceptibility to prosocial and anti-social influence. Of these, 205 participants reported their compliance with COVID-19 social distancing rules and attendance at social gatherings between June and August 2020. Bayesian ordinal regression models were used to predict adherence to social distancing from predictors, controlling for age at pandemic, gender, day of assessment, and intervention group. The results indicated that higher levels of prosociality, altruism and lower susceptibility to anti-social influence were associated with higher adherence to social distancing. Pre-pandemic levels of depression, anxiety, delayed reward discounting, rejection sensitivity, conduct problems and emotional awareness were not robustly related to the outcomes. These findings have implications for understanding how adolescents comply with public health guidelines, highlighting the role of social influence and peer norms.

Do Adolescents Adopt the Prosocial Behaviors of the Classmates They Like? A Social Network Analysis on Prosocial Contagion

While the influence of high-status peers on maladaptive behaviors is well-documented, socialization processes of prosocial behavior through high-status peers remain understudied. This study examined whether adolescents' prosocial behavior was influenced by the prosocial behavior of the peers they liked and whether this effect was stronger when the peers they liked were also well-liked by their classmates. Three waves of data, six months apart, were collected among Chilean early adolescents who completed peer nominations and ratings at Time 1 (n = 294, Mage = 13.29, SD = 0.62; 55.1% male), Time 2 (n = 282), and Time 3 (n = 275). Longitudinal social network analyses showed that adolescents adopted the prosocial behavior of the classmates they liked - especially if these classmates were well-liked by peers in general. In addition, adolescents low in likeability were more susceptible to this influence than adolescents high in likeability. The influence resulted both in increases and - especially - decreases in prosocial behavior, depending on the level of prosociality of the liked peer. Findings suggest that likeability represents an important aspect of peer status that may be crucial for understanding the significance of peer influence with respect to prosocial behaviors during adolescence.

Food choice mimicry on a large university campus

Social influence is a strong determinant of food consumption, which in turn influences the environment and health. Purchasing mimicry, a phenomenon where a person copies another person's purchases, has been identified as the key governing mechanism. Although consistent observations have been made on the role of purchasing mimicry in driving similarities in food consumption, much less is known about the precise prevalence, the affected subpopulations, and the food types most strongly associated with mimicry effects. Here, we study social influence on food choice through carefully designed causal analyses, leveraging the sequential nature of shop queues on a large university campus. In particular, we consider a large number of adjacent purchases where a focal user immediately follows another user ("partner") in the checkout queue and both make a purchase. Across food additions purchased during lunchtime together with a meal, we find that the focal user is significantly more likely to purchase the food item when the partner buys the item, vs. when the partner does not, increasing the purchasing probability by 14% in absolute terms, or by 83% in relative terms. The effect is observed across all food types, but largest for condiments. Furthermore, purchasing mimicry is present across age, gender, and status subpopulations, but strongest for students and the youngest. We elucidate the behavioral mechanism of purchasing mimicry, and derive direct implications for interventions improving dietary behaviors on campus, such as facilitating preordering to reduce detrimental interactions.

Positioning adolescence in the developmental timeline

Adolescence, the second decade of life, bridges childhood and adulthood, but also represents a host of unique experiences that impact health and well-being. Lifespan theories often emphasize the continuity of individual characteristics and their contexts from childhood to adolescence, underscoring the distal influence of childhood experiences. Yet, adolescence is marked by transitions that may provoke discontinuities, particularly within individuals, their contexts, and their interactions within those contexts. These discontinuities occur at varied times, orders, and intensities for individual youth, suggesting that adolescence may be a developmental turning point where earlier life experiences may be mediated, reversed, or transformed by proximal events. This perspective piece emphasizes the importance of considering transitions, discontinuities, and developmental turning points in adolescence as well as their potential to explain heterogeneity in adolescent and adult outcomes. We explore one biological and one contextual transition in adolescence and highlight innovative theories and methods for investigating continuity and discontinuity dynamics across development, which could lead to new insights related to the adolescent period and its importance in shaping future life trajectories.

Testing the Moderating Effect of Anti-Prejudice Motivation and Peer Attitudes on the Effectiveness of a School-Based Vicarious Contact Intervention

Vicarious contact has often been used for studying prejudice-reduction in school contexts due to its relatively accessible application through written or audiovisual portrayals of positive intergroup contact. However, these interventions may sometimes prove ineffective, thus restricting their ecological validity and independent use in education. To contribute to the understanding of factors that might facilitate or mitigate the efficacy of vicarious contact in reducing ethnic prejudice among adolescents, the present study tested for the moderating effect of anti-prejudice motivation and friends' outgroup attitudes. Participants were Finnish secondary school students (N = 334; M = 13.38 years, SD = 0.53; 48% female; 19% ethnic minority) allocated into cluster-randomized intervention (N = 149) and control (N = 185) groups. Participants in the intervention group took part in 4 × 45-min teacher-led intervention sessions. A pretest-posttest design was employed to assess the outgroup attitudes three weeks before the intervention and the follow-up two weeks after. The results showed that adolescents' intrinsic, but not extrinsic, anti-prejudice motivation and the pre-intervention attitudes of their reciprocal classroom friends positively predicted post-intervention attitudes towards people from different ethnic and cultural groups. However, only extrinsic motivation moderated the intervention effect as the results indicated the intervention to have a detrimental effect on outgroup attitudes among adolescents with less motivation to be non-prejudiced in order to gain social acceptance. This attitudinal backlash among adolescents less susceptible to the social influence of others implies that motivational aspects should not be overlooked when developing school-based intervention programs, especially when social norms are used as a mechanism of attitude change.

Valence-Dependent Implicit Action Generalization Among Group Members

People implicitly generalize the actions of known individuals in a social group to unknown members. However, actions have social goals and evaluative valences, and the extent to which actions with different valences (helpful and harmful) are implicitly generalized among group members remains unclear. We used computer animations to simulate social group actions, where helping and hindering actions were represented by aiding and obstructing another's climb up a hill. Study 1 found that helpful actions are implicitly expected to be shared among members of the same group but not among members of different groups, but no such effect was found for harmful actions. This suggests that helpful actions are more likely than harmful actions to be implicitly generalized to group members. This finding was replicated in Study 2 by increasing the group size from three to five. Study 3 found that the null effect for generalizing harmful actions among group members is not due to the difficulty of detecting action generalization, as both helpful and harmful actions are similarly generalized within particular individuals. Moreover, Study 4 demonstrated that weakening social group information resulted in the absence of implicit generalization for helpful actions, suggesting the specificity of group membership. Study 5 revealed that the generalization of helping actions occurred when actions were performed by multiple group members rather than being repeated by one group member, showing group-based inductive generalization. Overall, these findings support valence-dependent implicit action generalization among group members. This implies that people may possess different knowledge regarding valenced actions on category-based generalization.

The social transmission of empathy relies on observational reinforcement learning

Theories of moral development propose that empathy is transmitted across individuals. However, the mechanisms through which empathy is socially transmitted remain unclear. Here, we combine computational learning models and functional MRI to investigate whether, and if so, how empathic and non-empathic responses observed in others affect the empathy of female observers. The results of three independent studies showed that watching empathic or non-empathic responses generates a learning signal that respectively increases or decreases empathy ratings of the observer. A fourth study revealed that the learning-related transmission of empathy is stronger when observing human rather than computer demonstrators. Finally, we show that the social transmission of empathy alters empathy-related responses in the anterior insula, i.e., the same region that correlated with empathy baseline ratings, as well as its functional connectivity with the temporoparietal junction. Together, our findings provide a computational and neural mechanism for the social transmission of empathy that accounts for changes in individual empathic responses in empathic and non-empathic social environments.

Prosocial behaviours and emotional intelligence as factors associated with healthy lifestyles and violence in adolescents

Adolescence is a stage of life characterised by vulnerability, which shapes young people's trajectories and potentially influences their behaviour. In this crucial period, the promotion of prosocial behaviours and the development of emotional intelligence are understood as key factors influencing adolescents' psychological and personal well-being. The general objective of this study was to find out the relationship between these two variables - prosocial behaviours and emotional intelligence - and their correlation with the maintenance of a healthy lifestyle and another fundamental aspect such as violence among young people in the academic context. A total of 743 secondary school students participated in this research with a descriptive-cross-sectional design. This study used several instruments, including an ad hoc questionnaire to assess socio-demographic aspects and school violence, the Prosocial Behaviour Questionnaire (PBQ), the TMMS-24 for the assessment of Emotional Intelligence, the Healthy Lifestyles Questionnaire (HLQ-II) and the Satisfaction with Life Scale (SLS). The results highlighted a convincing link between the display of prosocial behaviours and emotional intelligence with various dimensions of healthy living such as healthy diet or respect for mealtimes. In particular, the research revealed a pronounced correlation between adolescents who showed greater emotional repair and respect and their lower involvement in school violence and substance use. In addition, the likelihood of having a healthy life was found to be linked to variables such as being male, respect, social relationships and emotional repair. In contrast, the likelihood of having an excessive consumption of certain harmful substances such as alcohol or tobacco was found to be linked to age, empathy and emotional clarity. These results highlight the crucial role that prosocial behaviours and emotional intelligence play in shaping adolescents' lives. In conclusion, the need to promote such variables as prosocial behaviours and emotional intelligence in adolescent students in order to promote healthy lifestyles and reduce school violence and substance use in this age group is discussed.

Life-Course Brain Health as a Determinant of Late-Life Mental Health: American Association for Geriatric Psychiatry Expert Panel Recommendations

This position statement of the Expert Panel on Brain Health of the American Association for Geriatric Psychiatry (AAGP) emphasizes the critical role of life course brain health in shaping mental well-being during the later stages of life. Evidence posits that maintaining optimal brain health earlier in life is crucial for preventing and managing brain aging-related disorders such as dementia/cognitive decline, depression, stroke, and anxiety. We advocate for a holistic approach that integrates medical, psychological, and social frameworks with culturally tailored interventions across the lifespan to promote brain health and overall mental well-being in aging adults across all communities. Furthermore, our statement underscores the significance of prevention, early detection, and intervention in identifying cognitive decline, mood changes, and related mental illness. Action should also be taken to understand and address the needs of communities that traditionally have unequal access to preventive health information and services. By implementing culturally relevant and tailored evidence-based practices and advancing research in geriatric psychiatry, behavioral neurology, and geroscience, we can enhance the quality of life for older adults facing the unique challenges of aging. This position statement emphasizes the intrinsic link between brain health and mental health in aging, urging healthcare professionals, policymakers, and a broader society to prioritize comprehensive strategies that safeguard and promote brain health from birth through later years across all communities. The AAGP Expert Panel has the goal of launching further activities in the coming months and years.

Sensitivity and specificity in affective and social learning in adolescence

Adolescence is a period of heightened affective and social sensitivity. In this review we address how this increased sensitivity influences associative learning. Based on recent evidence from human and rodent studies, as well as advances in computational biology, we suggest that, compared to other age groups, adolescents show features of heightened Pavlovian learning but tend to perform worse than adults at instrumental learning. Because Pavlovian learning does not involve decision-making, whereas instrumental learning does, we propose that these developmental differences might be due to heightened sensitivity to rewards and threats in adolescence, coupled with a lower specificity of responding. We discuss the implications of these findings for adolescent mental health and education.

Exploring the mechanistic pathways of how social network influences social norms in adolescent smoking prevention interventions

We know little about how smoking prevention interventions might leverage social network structures to enhance protective social norms. In this study we combined statistical and network science methods to explore how social networks influence social norms related to adolescent smoking in school-specific settings in Northern Ireland and Colombia. Pupils (12-15 years old) participated in two smoking prevention interventions in both countries (n = 1344). A Latent Transition Analysis identified three groups characterized by descriptive and injunctive norms towards smoking. We employed a Separable Temporal Random Graph Model to analyze homophily in social norms and conducted a descriptive analysis of the changes in the students' and their friends' social norms over time to account for social influence. The results showed that students were more likely to be friends with others who had social norms against smoking. However, students with social norms favorable towards smoking had more friends with similar views than the students with perceived norms against smoking, underlining the importance of network thresholds. Our results support the notation that the ASSIST intervention takes advantage of friendship networks to leverage greater change in the students' smoking social norms than the Dead Cool intervention, reiterating that social norms are subject to social influence.

Susceptibility to prosocial and antisocial influence in adolescence following mindfulness training

Mindfulness training programmes have shown to encourage prosocial behaviours and reduce antisocial tendencies in adolescents. However, less is known about whether training affects susceptibility to prosocial and antisocial influence. The current study investigated the effect of mindfulness training (compared with an active control) on self-reported prosocial and antisocial tendencies and susceptibility to prosocial and antisocial influence. 465 adolescents aged 11-16 years were randomly allocated to one of two training programmes. Pre- and post-training, participants completed a social influence task. Self-reported likelihood of engaging in prosocial and antisocial behaviours did not change post-training, and regardless of training group, participants showed a higher propensity for prosocial influence than for antisocial influence. Finally, participants were less influenced by antisocial ratings following both training programmes.

Social influence in adolescence as a double-edged sword

Social learning is fundamental to human development, helping individuals adapt to changing circumstances and cooperate in groups. During the formative years of adolescence, the social environment shapes people's socio-cognitive skills needed in adulthood. Although peer influence among adolescents is traditionally associated with risky and unruly conduct, with long-term negative effects on educational, economic and health outcomes, recent findings suggest that peers may also have a positive impact. Here, we present a series of experiments with 10-20-year-olds (n = 146) showing that positive and negative peer effects reflect a domain-general factor of social information use which declines during adolescence. Exposure to disobedient peers provoked rule breaking, and selfish peers reduced prosocial behaviour, particularly in early adolescence. However, compliant peers also promoted rule compliance and fair peers increased prosociality. A belief formation task further revealed that younger adolescents tend to assimilate social information, while older adolescents prioritize personal views. Our results highlight early adolescence as a key window for peer-based interventions to improve developmental trajectories.

Can substance abuse media literacy increase prediction of drug use in students?

Objective

The present study aimed to determine the predictors of drug use among students based on the Extended Prototype willingness model (EPWM).

Methods

This cross-sectional study was performed at Hamadan universities. The participants were selected via multi-stage sampling. Finally, out of 721 students participated. The questionnaire consisted of four sections: (a) socio-demographic characteristics, (b) Questionnaire about the prototype willingness model constructs, (c) Questionnaire about the status of drug use behavior, (d) Substance Abuse Media Literacy (SAML) scale. Data were analyzed using a structural equations partial least squares confirmatory composite approach and SPSS-23.

Results

The mean age of students was of 23.47 ± 4.14 years. Based on results, behavioral willingness (β = 0.420, t-value = 9.010, p < 0.001) and behavioral intention (β = 0.291, t-value = 6.957, p < 0.001) significantly predicted drug use. The presented results of analysis, 66% of the variance of the drug use, 62% of the variable of the behavioral willingness, and 56% of the behavioral intention could be explained by the EPWM.

Conclusion

The present study demonstrated that EPWM could predict drug use in students. Therefore, designing and implementing educational and promotional intervention programs to reduce behavioral willingness and increase students’ skills in substance abuse media literacy is necessary to prevent drug use behavior.

What Does it Mean to be Susceptible to Influence? A Brief Primer on Peer Conformity and Developmental Changes that Affect it

Peer influence is a twofold process that entails a behavior by an agent of influence that elicits conformity from the target of influence. Susceptibility describes the likelihood that conformity will occur. This review focuses on factors that shape susceptibility to peer influence. We argue that conformity has two distinct sources. In some instances, conformity is a product of characteristics of the target of influence, operationalized as stable individual difference variables. Trait-like attributes associated with susceptibility to peer influence include conformity dispositions, social goals, resource acquisition strategies, vulnerabilities, and maturational status. In other instances, conformity is a product of the context in which the target is situated, operationalized as impermanent individual difference variables. State-like circumstances associated with susceptibility to peer influence include conditions of uncertainty, personal attributes that differ from the partner or group, perceived benefits of impression management, unmet social needs, and social referents and beliefs about their behavior. Empirical illustrations are provided. We close with a discussion of developmental changes hypothesized to impact variations in susceptibility to peer influence.

The Influence of Parenting and Friendship on Self-Esteem in Adolescents

BACKGROUND: Studies in psychology often discuss adolescents with their strong self-esteem as individuals who know themselves. Self-esteem development in adolescents. These adolescents begin to understand the changes of personality development starting from the cognitive aspect or thoughts, emotion, feeling, social, and physical aspects. AIM: This study consistently aimed at finding comprehensive evidence that positive parenting and friendship affect self-esteem in adolescents. METHODS: The population of this study was adolescents, namely 173 senior high school students consisting of 72 males and 100 females who were involved and participated in this study. The data analysis, in this study, was the 2 predictors for linear regression analysis. RESULTS: The results showed that parenting and friendship simultaneously influenced self-esteem formation in adolescents. Partially, the result of this study also showed that parenting affected self-esteem formation in adolescents. CONCLUSION: In conclusion, friendship showed a significant effect on self-esteem formation in adolescents. Thus, the hypotheses in this study were accepted.

It's right, but risky too: Inclusive behavior as a positive risk in adolescence

INTRODUCTION

Although adolescent risk-taking is often characterized as negative, more recent work focuses on risk as a spectrum of negative to positive behaviors. We propose inclusive behavior as a new category of positive risk-taking focused on helping and facilitating social belonging for those who are marginalized or excluded. We use a qualitative approach to explore adolescents' perceptions of the risks involved in inclusive behavior and the factors that motivate acting inclusively at school.

METHODS

30 focus groups were conducted at 16 middle and high schools across the United States. The cross-sectional sample consisted of 194 students in grades 6-12 (11-19 years old). Students were majority female (61%) and self-identified as white (68%). Data were analyzed using qualitative thematic analysis.

RESULTS

Students often perceived the decision to act inclusively as risky because it involved weighing uncertain outcomes, including potential costs (e.g. peer rejection) and rewards (e.g. friendship). Students primarily focused on the role of peer group influence, but also discussed how school norms, the identity of the peer they were trying to include, and their own motivations affected the perceived risk involved in acting inclusively.

CONCLUSIONS

This study provides an exploratory look at adolescents' experiences of inclusive behavior. Findings support the current conceptualization of positive risk-taking behavior and suggest a multi-level framework for inclusive risks. Exploring the factors that make inclusive behavior differentially risky across individuals and contexts is a first step towards understanding how inclusive behavior fits within the positive risk-taking framework and designing interventions to reduce the risks involved.
