Risk Taking in Adolescence: New Perspectives From Brain and Behavioral Science

ABSTRACT— Trying to understand why adolescents and young adults take more risks than younger or older individuals do has challenged psychologists for decades. Adolescents' inclination to engage in risky behavior does not appear to be due to irrationality, delusions of invulnerability, or ignorance. This paper presents a perspective on adolescent risk taking grounded in developmental neuroscience. According to this view, the temporal gap between puberty, which impels adolescents toward thrill seeking, and the slow maturation of the cognitive-control system, which regulates these impulses, makes adolescence a time of heightened vulnerability for risky behavior. This view of adolescent risk taking helps to explain why educational interventions designed to change adolescents' knowledge, beliefs, or attitudes have been largely ineffective, and suggests that changing the contexts in which risky behavior occurs may be more successful than changing the way adolescents think about risk.     

Sex-specific pathways to early puberty, sexual debut, and sexual risk taking: tests of an integrated evolutionary-developmental model

The current study tested sex-specific pathways to early puberty, sexual debut, and sexual risk taking, as specified by an integrated evolutionary-developmental model of adolescent sexual development and behavior. In a prospective study of 238 adolescents (n = 129 girls and n = 109 boys) followed from approximately 12-18 years of age, we tested for longitudinal relations between ecological stressors, family relationships, pubertal maturation, self-perceived mate value, and sexual risk taking in both boys and girls. Consistent with the theory, (a) higher levels of familial and ecological stress predicted earlier sexual debut and greater sexual risk taking; (b) pubertal maturation partially mediated these relations among girls but not among boys; (c) father absence had unique effects on female sexual outcomes but not on male sexual outcomes; (d) higher self-perceived mate value directly predicted earlier sexual debut and, through it, greater sexual risk taking; and (e) relations between pubertal maturation and early sexual debut were partially mediated by higher self-perceived mate value in boys but not in girls. Discussion focuses on the contribution of an integrated evolutionary-developmental theory to the adolescent sexual health literature.     

Effects of anonymous peer observation on adolescents' preference for immediate rewards

Research suggests that the presence of peers influences adolescent risk‐taking by increasing the perceived reward value of risky decisions. While prior work has involved observation of participants by their friends, the current study examined whether observation by an anonymous peer could elicit similarly increased reward sensitivity. Late adolescent participants completed a delay discounting task either alone or under the belief that performance was being observed from a neighboring room by an unknown viewer of the same gender and age. Even in this limited social context, participants demonstrated a significantly increased preference for smaller, immediate rewards when they believed that they were being watched. This outcome challenges several intuitive accounts of the peer effect on adolescent risk‐taking, and indicates that the peer influence on reward sensitivity during late adolescence is not dependent on familiarity with the observer. The findings have both theoretical and practical implications for our understanding of social influences on adolescents' risky behavior.

Neurobehavioral Changes in Adolescence

Adolescents across a variety of species exhibit age-specific behavioral characteristics that may have evolved to help them attain the necessary skills for independence. These adolescent-related characteristics, such as an increase in risk taking, may be promoted less by the hormonal changes of puberty than by developmental events occurring in brain. Among the prominent brain transformations of adolescence are alterations in the prefrontal cortex, limbic brain areas, and their dopamine input, systems that are sensitive to stressors and form part of the neural circuitry modulating the motivational value of drugs and other reinforcing stimuli. Such developmental transformations of the adolescent brain may predispose adolescents to behave in particular ways and make them particularly likely to initiate use of alcohol and other drugs.     

Positive and Negative Affect in Parents and Adolescents: Gender and Assessment Method Considerations

This study examined adolescents’ self-reports and parents’ reports of adolescents’ positive and negative affect toward their parents, as well as mothers’ and fathers’ self-reports of positive and negative affect toward their adolescents. Based on behavioral observations, adolescent–parent interactions were examined to determine the relation between adolescent–parent behavior, adolescents’ perceptions of parental affect, and parents’ perceptions of adolescent affect. Gender of adolescents, gender of parents, and adolescent gender by parent gender interaction effects were studied as was adolescents’ age. Findings suggest that parent gender (i.e., mothers and fathers) and adolescent gender (i.e., boys and girls) are important considerations when studying affect in parent–adolescent relationships. Age-related differences were not evident. Results are discussed with an eye toward improving the assessment of parent–adolescent affect by using multiple methods of assessment such as direct behavioral observations and multiple informants on questionnaire measures.     

Adolescent Self-Reports of Social Anxiety: Can They Disagree with Objective Psychophysiological Measures and Still Be Valid?

We examined self-reported and parent-reported adolescent social anxiety symptoms and objective baseline measures of psychophysiological flexibility in 62 families. Measures completed by 31 adolescents referred for a clinical screening evaluation for social anxiety were compared to an age- and gender-matched community control sample of 31 adolescents (total sample: age range 14 to 17?years; 22 boys and 40 girls; M?=?15.32?years; SD?=?1.1). Clinic referred adolescents reported significantly fewer social anxiety symptoms than parents reported about adolescents. Further, for all adolescents, self-reported social anxiety symptoms exhibited low correspondence with objective psychophysiological measures. Yet, both measures uniquely discriminated between adolescents on whether they were clinic referred for a social anxiety screening. Further, adolescent self-reported social anxiety symptoms exhibited high levels of internal consistency and convergent validity. Findings indicate that researchers and practitioners should refrain from using disagreements between adolescent self-reports and other measures (e.g., parent report, objective measures) as indicators of the veracity of adolescent self-reports.     

A Preliminary Validation of Preadolescents' Self-Reports Using the Five-Factor Model of Personality

Although self-reports using the Five-Factor Model (FFM) of personality have been used in both adult and adolescent populations, few studies have investigated preadolescents' ability to rate themselves using measures of the FFM. A total of 130 preadolescents (mean age = 10.79 years) rated their personalities using the NEO Five-Factor Inventory (NEO-FFI). When standardized verbal prompts were used to clarify the vocabulary in the NEO-FFI, preadolescents were able to reliably rate themselves across all traits of the FFM. Preadolescents' self-ratings were found to moderately agree with mothers' ratings of their children's personalities, suggesting not only the potential utility of using other-reports of preadolescent personality but also the appropriateness of using self-reports.     

A review of online social networking profiles by adolescents: implications for future research and intervention

This study explored content posted and interactions taking place on adolescent online social networking profiles. Although "blogging" continues to soar in popularity, with over half of teenagers online participating in some form, little research has comprehensively explored blog communication within the context of adolescent development. Content was qualitatively coded from 100 randomly selected profiles authored by adolescents between the ages of 16 and 18. Rich thematic elements were identified including family and social issues, risk behaviors, disclosure of personally identifiable information, and frequent peer interaction. Results indicate adolescent blogs frequently contain appropriate images, positive comments about parents and peers, athletics, a variety of risk behaviors, and sexual and profane language. In addition, school type was examined (public versus private, religious) as a potential factor in understanding the differences in content posted by adolescents; however, no significant differences were found. Implications for parental monitoring and intervention are discussed as well as direction for future research. Adolescents' online profiles contain a wealth of intimate, candid, and publicly available information on a wide range of social issues pertinent to adolescence that contribute to the understanding of adolescent development and well-being.     

Toward an empirical taxonomy of suicide ideation: a cluster analysis of the youth risk behavior survey

In this study we examined adolescent risk behaviors, giving special attention to suicide ideation. Cluster analysis was used to classify adolescents (N = 2,730) on the Youth Risk Behavior Survey. Six clusters of adolescent risk behavior were identified. Although each risk cluster was distinct, some clusters shared overlapping risk behaviors. Suicide ideation was central to two clusters: the Silent Suicide cluster and the Multiple Risk cluster. The findings demonstrate that suicide ideation is both a unique risk behavior for some adolescents and part of a generalized risk syndrome for other adolescents. A multiple subgroup framework is recommended for understanding adolescent risk behaviors.     

Body-image and eating disturbances predict onset of depression among female adolescents: a longitudinal study

This study examined data from a 4-year school-based longitudinal study (n = 1,124), to test whether the increase in major depression that occurs among girls during adolescence may be partially explained by the body-image and eating disturbances that emerge after puberty. Elevated body dissatisfaction, dietary restraint, and bulimic symptoms at study entry predicted onset of subsequent depression among initially nondepressed youth in bivariate analyses controlling for initial depressive symptoms. Although the unique effect for body dissatisfaction was not significant in the multivariate model, this set of risk factors was able to fairly accurately foretell which girls would go on to develop major depression. Results were consistent with the assertion that the body-image- and eating-related risk factors that emerge after puberty might contribute to the elevated rates of depression for adolescent girls.     

多主体评定青少年外化问题行为的一致性问题

以529名城乡初一学生为被试进行短期追踪研究,考察了青少年自我、同伴和教师三种主体对学校情境中的青少年外化问题行为评定的一致性问题。采用相关分析、多质多法分析、验证性因素分析和检出率分析对三种主体的评定结果进行了分析比较。结果显示,青少年自我、同伴和教师对外化问题行为的评定只存在中低程度的一致性;通过同伴评定测得的四种外化问题行为群之间的相关性高于通过教师评定和自我报告测得的结果,而自我报告测得的四种外化问题行为群之间的相关性最低。不同报告主体对青少年外化问题行为评定的跨时间稳定性存在差异,同伴评定的稳定性最高,其次为教师评定,青少年自我报告的稳定性最低。通过同伴评定测得的结果对多主体评定的解释率高于教师评定和自我报告的结果,自我报告的结果对多主体评定的解释率最低。三种主体所检出的不同形式的外化问题行为的人数比例没有呈现出规律性的差异,只有通过同伴评定检出的不同形式的外化问题行为者的人数比例随着检出标准的提高而减小     

Arousal, processing, and risk taking: consequences of intergroup anger

Intergroup emotions theory (IET) posits that when social categorization is salient, individuals feel the same emotions as others who share their group membership. Extensive research supporting this proposition has relied heavily on self-reports of group-based emotions. In three experiments, the authors provide converging evidence that group-based anger has subtle and less explicitly controlled consequences for information processing, using measures that do not rely on self-reported emotional experience. Specifically, the authors show that intergroup anger involves arousal (Experiment 1), reduces systematic processing of persuasive messages (Experiment 2), is moderated by group identification (Experiment 2, posttest), and compared to intergroup fear, increases risk taking (Experiment 3). These findings provide converging evidence that consistent with IET, emotions triggered by social categorization have psychologically consequential effects and are not evident solely in self-reports.     

It's Time We Brought Introspection Out of the Closet

ABSTRACT— I identify the main reasons why introspection unofficially has been banned from the field for some 100 years, though it has been partly smuggled back in through the use of "verbal (self-) reports." I then show why introspection is indispensable to psychology. I argue that this ban has retarded the progress of psychology by taking attention away from the problem of the accuracy of self-reports, limiting our understanding of concepts like emotion, discouraging psychologists from using introspection themselves, and ignoring the study of how to develop introspective skill. I conclude by suggesting some approaches to validating introspective reports.     

Peers increase adolescent risk taking by enhancing activity in the brain's reward circuitry

The presence of peers increases risk taking among adolescents but not adults. We posited that the presence of peers may promote adolescent risk taking by sensitizing brain regions associated with the anticipation of potential rewards. Using fMRI, we measured brain activity in adolescents, young adults, and adults as they made decisions in a simulated driving task. Participants completed one task block while alone, and one block while their performance was observed by peers in an adjacent room. During peer observation blocks, adolescents selectively demonstrated greater activation in reward-related brain regions, including the ventral striatum and orbitofrontal cortex, and activity in these regions predicted subsequent risk taking. Brain areas associated with cognitive control were less strongly recruited by adolescents than adults, but activity in the cognitive control system did not vary with social context. Results suggest that the presence of peers increases adolescent risk taking by heightening sensitivity to the potential reward value of risky decisions.     

Personality judgment and personality pathology: self-other agreement in adolescents with conduct disorder

We examine two issues linking personality pathology and judgment of traits within the Five-Factor Model of personality. We hypothesize that pathology moderates self-other agreement--"target" participants with pathology should be less judgable than participants without pathology. In addition, we hypothesize that pathology could partially produce agreement across a variety of traits, particularly those traits fundamental to the pathology. In an adolescent sample including a group with Conduct Disorder (CD) and a Control group, we examine agreement between adolescents' self-reports and their mothers' informant reports. Using trait-centered and person-centered perspectives, we find support for both hypotheses. Results have implications for understanding the processes affecting personality judgment, for increasing integration of traditional personality research and personality pathology, and for personality assessment.     

Prevalence of suicidal ideation among boys and men assessed annually from ages 9 to 29 years

In a sample of 206 boys (90% Caucasian), self-reported suicidal ideation (SI; ages 12 to 29) and parent-reported youth suicidal talk (ages 9 to 20) were assessed annually by questionnaire. One-week point prevalence of self-reported SI ranged from 2.6% to 16.3%. New cases emerged across adolescence; by age 29, 57.3% self-reported SI at least once. SI was associated with clinically significant elevations on concurrent depressive symptoms. Nearly one quarter (24.8%) of parents reported suicidal talk by their son by age 20. Parent- and self-reports showed low correspondence. SI was more common than retrospective studies suggest. Parent-reports and one-time self-reports are likely to miss large numbers of adolescent boys who may be at risk.     

The Big Five and enduring marriages

The present investigation tested the relations between the Big Five dimensions of personality and the marital relationships of over 400 couples using both observational and questionnaire data. Four major findings emerged from these analyses. First, self-reports of neuroticism were positively correlated with negative interactions and negatively correlated with global evaluations of the marriage. Second, self-reports of agreeableness were negatively correlated with negative interactions and generally positively correlated with global evaluations of the marriage. Third, self-reports of openness were negatively correlated with observer reports of negative interactions. Fourth, self-reports of openness by wives were positively correlated with global reports of sexual satisfaction. These findings suggest that agreeableness and openness deserve increased attention as significant correlates of close relationships. Discussion emphasizes the importance of intrapersonal factors for understanding marital relationships.     

Dying for romance: risk taking as purposive behavior

Many approaches have been utilized to understand adolescent risk taking. The current research frames risk taking as a purposive behavior enacted with a specific goal in mind. Rather than assuming adolescent risk taking to be the result of arrogance or perceived invulnerability, adolescent risk taking is interpreted as a means to an end. Stemming from a Tolmanian framework, an alternative explanation for adolescent risk taking is tested: adolescents are willing to take risks to the extent that the risk is associated with a needed outcome - the greater the need for the outcome, the greater the willingness to take risks. To test the proposed hypothesis, 192 participants completed a survey about their need for a romantic relationship and their willingness to endure harm to obtain a romantic relationship. Data were collected at two time points. A hierarchical regression revealed that need for romance is a significant predictor of willingness to endure harm for romance, even after gender and sensation seeking are statistically controlled. Moreover, need for romance at T1 was shown to be predictive of harm for romance at T2. Results are supportive of taking a purposive - that is, Tolmanian - approach, as a means for interpreting adolescent behavior.     

Pubertal development and behavior: Hormonal activation of social and motivational tendencies

Adolescence is a time of dramatic changes including rapid physical growth, the onset of sexual maturation, the activation of new drives and motivations, and a wide array of social and affective changes and challenges. This review focuses on behavioral changes in this interval and is organized by the claim that a key set of these adolescent changes are part of a more general re-orientation of social behavior. More specifically we hypothesize that pubertal maturation is associated with the activation of social and motivational tendencies, which in turn influence behavior and emotion in adolescence depending upon interactions with social context. We focus on evidence for two examples of these motivational changes: (1) increases in sensation-seeking (motivational tendency to want to experience high-intensity, exciting experiences) and (2) stronger natural interest in—and pursuit of—contact with peers and potential romantic partners. We consider how these motivational changes contribute to the broader social re-orientation of adolescence, including exploration of social experiences, development of skills and knowledge relevant to taking on adult social roles, individuation from family, and establishment of an individual identity, all of which represent core developmental tasks during this period in the life span ( 9, 16 and 62). The paper also emphasizes the importance of investigating and understanding the direct influences of puberty on behavior and disentangling these from the broader set of changes during adolescent development.
