Adolescent psychopathic traits and adverse environments: Associations with socially adaptive outcomes.

Researchers have suggested that psychopathic traits among adults may be, at least in part, an adaptive and/or a learned response for securing socially adaptive outcomes in adverse environments, but there is a lack of developmental evidence supporting this hypothesis among adolescents. Therefore, we examined the indirect links from self-perceived adverse environments (parental neglect, socioeconomic status, school competition, neighborhood violence) to evolutionarily relevant social outcomes (social power, dating behavior) through psychopathic traits. A community sample of 396 adolescents completed measures for the study (Mage = 14.64, SD = 1.52). As predicted, there were significant indirect effects from higher levels of parental neglect, school competition, and neighborhood violence to both forms of socially adaptive outcomes through psychopathic traits, but unexpectedly, there were no indirect effects with socioeconomic status. There were also direct effects between environment and socially adaptive outcomes. Results support the hypothesis that psychopathic traits may be, in part, an adaptive and/or learned response to cues from adverse social environments as a means to acquire evolutionarily relevant social outcomes. Interventions could be designed to target the adverse social issues that might be facilitating the development of psychopathy and should be sensitive to the social outcomes adolescents may acquire from these traits.

Social Media Friendship Jealousy.

A new measure to assess friendship jealousy in the context of social media was developed. This one-factor, seven-item measure was psychometrically sound, showing evidence of validity and reliability in three samples of North American adults (Study 1, n = 491; Study 2, n = 494; Study 3, n = 415) and one-, two-, and three-year stability (Study 3). Women reported more social media friendship jealousy than men (Studies 2 and 3) and younger women had the highest levels of social media friendship jealousy (compared with younger men and older men and women; Study 2). Social media friendship jealousy was associated with lower friendship quality (Study 1) and higher social media use and trait jealousy (Study 2). The relation between social media friendship jealousy and internalizing symptoms indicated positive within time associations and longitudinal bidirectional relations (Study 3). Specifically, social media friendship jealousy predicted increases in internalizing problems, and internalizing problems predicted greater social media friendship jealousy accounting for gender and trait levels of social media friendship jealousy and internalizing problems. Anxious and depressed adults may be predisposed to monitor threats to their friendships via social media and experience negative consequences because of this behavior. Although social media interactions can be associated with positive well-being and social connectedness, our results highlight that they can also undermine friendships and mental health due to jealousy.

Does adolescent incivility longitudinally predict future bullying?

INTRODUCTION: Adolescent bullying is a complicated behavior that is difficult to prevent. Understanding factors that predict bullying during adolescence can help us minimize such behavior. Classroom incivility is a low-level antisocial behavior that has been discussed in the literature as being a potential predictor of bullying in adolescence. Therefore, the goal of the present study was to examine the longitudinal link between classroom incivility and bullying. METHODS: Data for the current study was collected using quantitative surveys at two-time points, three years apart (November 2019 and November 2022) in southern Ontario, Canada. Our sample comprised 349 adolescents (51.3% boys, 46.4% girls, 0.6% other, and 1.7% preferred not to say) between the ages of 9 and 14 years old (M = 11.92 years; SD = 1.42). We utilized cross-lagged analyses to examine the stability of classroom incivility in adolescence, and the longitudinal association between classroom incivility and bullying. RESULTS: Classroom incivility at Time 1 predicted bullying behavior at Time 2, while bullying at Time 1 did not predict classroom incivility at Time 2. Our results not only support the stability of levels of classroom incivility across time, but also provide empirical support for classroom incivility as a precursor to bullying behavior. CONCLUSION: Our study suggests that classroom incivility can not only negatively impact the learning environment but may also be implicated in contributing to the circumstances that promote bullying behavior in adolescence, highlighting the importance of limiting uncivil behavior before it escalates into more severe forms of behavior.

Bullying and the Abuse of Power.

Dan Olweus pioneered research on school bullying and identified the importance of, and risk factors associated with, bullying and victimization. In this paper, we conduct a narrative review of the critical notion of power within bullying. Specifically, we discuss Olweus's definition of bullying and the role of a power imbalance in distinguishing bullying behavior from other forms of aggression. Next, we discuss the changing nature of research on aggression (and the adaptiveness of aggression) throughout the years, the important role of power in these changes, and how the concept of power in relationships has helped elucidate the developmental origins of bullying. We discuss bullying interventions and the potential opportunities for interventions to reduce bullying by making conditions for bullying less favorable and beneficial. Finally, we discuss bullying and the abuse of power that extends beyond the school context and emerges within families, workplaces, and governments. By recognizing and defining school bullying as an abuse of power and a violation of human rights, Olweus has laid the foundation and created the impetus for researching and addressing bullying. This review highlights the importance of examining abuses of power not only in school relationships, but across human relationships and society in general.

Evolutionarily relevant aggressive functions: Differentiating competitive, impression management, sadistic and reactive motives.

This study investigated early adolescents' (ages 9-14; M = 11.91) self-reported, evolutionarily relevant motives for using aggression, including competitive, impression management, sadistic, and reactive functions, and examined differential relations with a range of psychosocial characteristics. As expected, competitive functions were associated with aggression and victimization in which the perpetrator had equal or less power than the victim, in line with the view that these are aversive and appetitive motives related to competition with rivals. Impression management and sadistic functions were associated with bullying and coercive resource control strategies (the latter for boys only), consistent with expectations that these are appetitive motives, with the former being more goal-directed and the latter somewhat more impulsive. Finally, as hypothesized, reactive functions were associated with emotional symptoms, hostility, victimization by bullying, and aggression by perpetrators with equal or less power than the victim, consistent with theory and research conceptualizing reactive aggression as an impulsive, emotion-driven response to provocation. The benefits of studying a wide range of evolutionarily relevant aggressive functions are discussed.

The influence of demographics and personality on COVID-19 coping in young adults.

The global COVID-19 pandemic has had an unprecedented effect on human behavior and well-being. Demographic factors and personality traits have been shown to independently influence whether individuals adopt adaptive or maladaptive coping responses. However, to date, researchers have not considered how demographics and personality could interact to influence COVID-19 coping responses. In a sample of 516 North American young adults, we found direct links from two demographic factors (i.e., income and having children) and from multiple personality traits (as captured by the HEXACO model) to adaptive and maladaptive COVID-19 coping responses. We also found that personality indirectly linked a broader range of demographic factors (income, age, gender, having children) with COVID-19 coping responses. We encourage future research on COVID-19 coping responses to consider not just the individual contributions of demographics and personality, but their interdependent influence on whether individuals adopt more or less adaptive COVID-19 pandemic coping responses.

Bullying when it's hot? The CLASH model and climatic influences on bullying.

A novel predictor of bullying may be underlying regional weather conditions (i.e., climate). Bullying data support the CLASH model of aggression by suggesting that climate may moderate the forms and severity of bullying, as well as predict its prevalence across countries. Furthermore, bullying data also suggest that the CLASH model may apply to forms of aggression beyond reactive aggression.

Physical and relational bullying and victimization: Differential relations with adolescent dating and sexual behavior.

Taking an evolutionary psychological perspective, we investigated whether involvement in bullying as a perpetrator or victim was more likely if adolescents reported having more dating and sexual partners than their peers, an indication of greater engagement in competition for mates. A total of 334 adolescents (173 boys, 160 girls) between the ages of 12 and 16 years (M = 13.6, SD = 1.3), recruited from community youth organizations, completed self-report measures of physical and relational bullying and victimization, as well as dating and sexual behavior. As predicted, pure physical bullying was positively associated with the number of dating and sexual partners, primarily for adolescent boys. Adolescent girls with more dating partners had greater odds of being relational bully-victims, in line with predictions. Finally, adolescent girls with more sexual partners were at greater risk of being physically victimized by peers, and greater involvement with dating and sexual partners was associated with higher odds of being a physical bully-victim. Results are discussed with respect to evolutionary theory and research in which adolescent boys may display strength and athleticism through physical bullying to facilitate intersexual selection, whereas relational bullying may be employed as a strategy to engage in intrasexual competition with rivals for mates.

The Meaningful Roles Intervention: An Evolutionary Approach to Reducing Bullying and Increasing Prosocial Behavior.

Bullying is a problem that affects adolescents worldwide. Efforts to prevent bullying have been moderately successful at best, or iatrogenic at worst. We offer an explanation for this limited success by employing an evolutionary-psychological perspective to analyze antibullying interventions. We argue that bullying is a goal-directed behavior that is sensitive to benefits as well as costs, and that interventions must address these benefits. This perspective led us to develop a novel antibullying intervention, Meaningful Roles, which offers bullies prosocial alternatives-meaningful roles and responsibilities implemented through a school jobs program and reinforced through peer-to-peer praise notes-that effectively meet the same status goals as bullying behavior. We describe this new intervention and how its theoretical evolutionary roots may be applicable to other intervention programs.

Relations between adolescent ratings of Rothbart's temperament questionnaire and the HEXACO personality inventory.

Conventionally, individual differences have been assessed using temperament measures for infants and children, and personality measures for adults. We chose to explore both temperament and personality to see whether a convergence exists specifically during adolescence. A sample of 225 adolescents completed Rothbart's Early Adolescent Temperament Questionnaire-Revised (EATQ-R), a 4-factor temperament scale, and the HEXACO Personality Inventory-Revised (HEXACO PI-R), a 6-factor personality scale. As hypothesized, we found significant relations between the 2 measures. However, there were some important differences between the 2 measures regarding Honesty-Humility, Openness, and Frustration that highlight the unique contributions of both instruments to understanding and measuring adolescent individual differences. As there is a relatively scant history of measuring temperament or personality in adolescence, it is sometimes difficult for researchers to decide which instrument is most appropriate. The results reported here suggest that either the EATQ-R or the HEXACO PI-R could be appropriate, depending on the specific research questions being asked.

Adolescent Bullying, Dating, and Mating : Testing an Evolutionary Hypothesis.

Traditionally believed to be the result of maladaptive development, bullying perpetration is increasingly being viewed as a potentially adaptive behavior. We were interested in determining whether adolescents who bully others enjoy a key evolutionary benefit: increased dating and mating (sexual) opportunities. This hypothesis was tested in two independent samples consisting of 334 adolescents and 144 university students. The data partly supported our prediction that bullying, but not victimization, would predict dating behavior. The data for sexual behavior more clearly supported our hypothesis that bullying behavior predicts an increase in sexual opportunities even when accounting for age, sex, and self-reports of attractiveness, likeability, and peer victimization. These results are generally congruent with the hypothesis that bullying perpetration is, at least in part, an evolutionary adaptive behavior.

Is adolescent bullying an evolutionary adaptation?

Bullying appears to be ubiquitous across cultures, involving hundreds of millions of adolescents worldwide, and has potentially serious negative consequences for its participants (particularly victims). We challenge the traditionally held belief that bullying results from maladaptive development by reviewing evidence that bullying may be, in part, an evolved, facultative, adaptive strategy that offers some benefits to its practitioners. In support of this view, we draw from research that suggests bullying serves to promote adolescent bullies' evolutionarily-relevant somatic, sexual, and dominance goals, has a genetic basis, and is widespread among nonhuman animals. We identify and explain differences in the bullying behavior of the two sexes, as well as when and why bullying is adaptive and when it may not be. We offer commentary on both the failures and successes of current anti-bullying interventions from an evolutionary perspective and suggest future directions for both research and anti-bullying interventions.

The evolutionary basis of risky adolescent behavior: implications for science, policy, and practice.

This article proposes an evolutionary model of risky behavior in adolescence and contrasts it with the prevailing developmental psychopathology model. The evolutionary model contends that understanding the evolutionary functions of adolescence is critical to explaining why adolescents engage in risky behavior and that successful intervention depends on working with, instead of against, adolescent goals and motivations. The current article articulates 5 key evolutionary insights into risky adolescent behavior: (a) The adolescent transition is an inflection point in development of social status and reproductive trajectories; (b) interventions need to address the adaptive functions of risky and aggressive behaviors like bullying; (c) risky adolescent behavior adaptively calibrates over development to match both harsh and unpredictable environmental conditions; (d) understanding evolved sex differences is critical for understanding the psychology of risky behavior; and (e) mismatches between current and past environments can dysregulate adolescent behavior, as demonstrated by age-segregated social groupings. The evolutionary model has broad implications for designing interventions for high-risk youth and suggests new directions for research that have not been forthcoming from other perspectives.

Supporting fathering through infant massage.

Fathers may feel dissatisfied with their ability to form a close attachment with their infants in the early postpartum period, which, in turn, may increase their parent-related stress. Our study sought to determine if an infant massage intervention assisted fathers with decreasing stress and increasing bonding with their infants during this time. To address the complex father-infant relationship, we conducted a pilot study using a mixed methodology approach. Twelve infant-father dyads participated in the intervention, and 12 infant-father dyads populated a wait-list control group. Paternal stress was measured using the Parenting Stress Index at baseline and at postintervention. We found infant massage instruction significantly decreased paternal stress. Our findings were also supported by the qualitative data and suggest fathers may benefit from applied postnatal education.

Paternal care may influence perceptions of paternal resemblance.

Father-child resemblance is increasingly attracting attention from researchers interested in studying paternal investment. The current study sought to determine whether a quasi-experimental infant massage intervention would increase father's perceptions of resemblance. The study included a dozen fathers in each of two groups: the first received an intensive series of lessons on infant-father massage along with their infants, while the second group served as a neutral control. We failed to find significant correlations between paternal investment and resemblance, but we found that fathers who participated in the infant massage intervention reported significantly larger post-study ratings of resemblance and lower ratings of paternal stress. This suggests that the relationship between father-child resemblance and paternal investment may be bidirectional.

Cues of high and low body weight negatively influence adults' perceptions and ratings in the hypothetical adoption paradigm.

Infant and child facial cues influence perceptions and ratings in the Hypothetical Adoption Paradigm as well as actual parental care. A previous study demonstrated that infant and child facial cues of low body weight negatively influenced adults' ratings. The current study sought to replicate and expand on those results by presenting adults with normal faces as well as faces that were digitally altered to display high or low body weight. Cues of abnormal body weight significantly, and negatively, influenced adults' ratings of adoption preference, health, and cuteness. Effect sizes were larger for cues of high body weight. Thus, infant and child facial cues of abnormal body weight may represent a relative risk factor to the quality of adult care obtained by children with abnormal body weight.

Influence of infant and child facial cues of low body weight on adults' ratings of adoption preference, cuteness, and health.

Infant and child facial cues have been shown to influence decisions and perceptions associated with parental care in adults. Low body weight reflects health problems in infants and children; therefore, facial cues associated with low body weight may influence adult cognitive processes associated with parental care and investment. Facial images of infants and children were digitally manipulated to simulate cues of low body weight and presented to adults using a hypothetical adoption paradigm. Participants' ratings of adoption preference, cuteness, and health were significantly lower for the digitally manipulated low body weight facial images than their unaltered counterparts. These findings support the hypothesis that facial cues of poor health negatively influence adults' responses to infants and children.
