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. 相似文献

In the search for ever earlier determinants of adult pathology many ignore the transformative impact of adolescence. The authors suggest that the reality of adolescent development creates a vulnerability to being overwhelmed. Through deferred action childhood experiences may interact with adolescent realities and omnipotent beliefs to traumatize the adolescent. The authors suggest that trauma in adolescence can be independent both of the intensity of current external exposure or of earlier traumatic experiences. 相似文献

Outcome following traumatic brain injury (TBI) has been frequently evaluated for adults, although there has been minimal research on adolescents with TBI. It has been argued that TBI sequelae may be more difficult for adolescents to adjust to given developmental changes in physical (puberty), interpersonal (self-concept), and environmental domains (transition to college). In addition, it is commonly acknowledged that moderator variables such as psychiatric history, family functioning, substance use, and sexuality impact functional outcome following TBI, although it is often difficult to objectively evaluate these variables. The current study examined relationships among TBI-related deficits, moderator variables, and academic outcomes for six adolescents transitioning to college. The findings suggest that it may not be appropriate to predict functional outcome based solely on objective neuropsychological results. However, moderator variables appear to have a more direct relationship with outcome, depending on the moderator variable and the individual. 相似文献

The Network Constellation of Personality and Substance Use: Evolution from Early to Late Adolescence
Mohammad H. Afzali Sherry Heather Stewart Jean R. Séguin Patricia Conrod 《欧洲人格杂志》2020,34(6):1109-1119
There is a well-established link between substance use and four personality traits of anxiety–sensitivity, hopelessness, impulsivity, and sensation-seeking. However, construct-level models of personality may conceal indicator-level personality–outcome associations. The current study aims to investigate evolution of the network constellation of personality and cannabis/alcohol use from early to late adolescence. Data comes from the longitudinal Co-Venture cohort (N = 3800). Personality indicators, measured by Substance Use Risk Profile Scale (SURPS) items, and the frequency of cannabis/alcohol use were assessed at four consecutive years (13–17 years old). Network constellations of the SURPS items and cannabis/alcohol use were estimated using Bayesian Gaussian graphical models at four time points. Results highlighted the age-specific associations between personality indicators and substance use. The positive role of the sensation-seeking trait (e.g. attitude towards transgression) was constant, whereas the positive role of hopelessness indicators (e.g. not being enthusiastic about future) and the negative role of anxiety–sensitivity indicators (e.g. fear of having unusual body sensations) were more prominent at early adolescence. The current study provides a novel perspective on the network structure of personality and substance use in adolescence and suggests substance-specific and age-adjusted targets in intervention efforts. © 2020 European Association of Personality Psychology 相似文献

While much research on adolescent risk behaviour has focused on the development of prefrontal self-regulatory mechanisms, prior studies have elicited mixed evidence of a relationship between individual differences in the capacity for self-regulation and individual differences in risk taking. To explain these inconsistent findings, it has been suggested that the capacity for self-regulation may be, for most adolescents, adequately mature to produce adaptive behaviour in non-affective, “cold” circumstances, but that adolescents have a more difficult time exerting control in affective, “hot” contexts. To further explore this claim, the present study examined individual differences in self-control in the face of affective and non-affective response conflict, and examined whether differences in the functioning of cognitive control processes under these different conditions was related to risk taking. Participants completed a cognitive Stroop task, an emotional Stroop task, and a risky driving task known as the Stoplight game. Regression analyses showed that performance on the emotional Stroop task predicted laboratory risk-taking in the driving task, whereas performance on the cognitive Stroop task did not exhibit the same trend. This pattern of results is consistent with theories of adolescent risk-taking that emphasise the impacts of affective contextual influences on the ability to enact effective cognitive control. 相似文献

Attachment theory asserts that secure attachment representations are developed through sensitive and consistent caregiving. If sensitive caregiving is a constant characteristic of the parent, then siblings should have concordant attachment classifications. The authors explored maternal attachment quality assessed by the Attachment Q-Set, maternal sensitivity, and specific mother–child interactions between siblings. Hour-long observations took place in the homes of 9 preschool sibling pairs and their immediate caregivers. The interactions were analyzed using a modified version of Bales’ Small Group Analysis. The results reveal attachment discordance in a third of sibling pairs. While maternal sensitivity was higher with older siblings and mothers displayed more positive emotions when interacting with their younger siblings, attachment quality was not associated with birth order. Therefore, a shift toward a more contextual, family-based perspective of attachment is recommended to further understand how attachment strategies are created and maintained within the child's everyday context. 相似文献

Poor decision making during adolescence occurs most frequently when situations
are emotionally charged. However, relatively few studies have measured the
development of cognitive control in response to emotional stimuli in this
population. This study used both affective (emotional faces) and non-affective
(letter) stimuli in two different flanker tasks to assess the ability to ignore
task-irrelevant but distracting information, in 25 adults and 25 adolescents. On
the non-emotional (letter) flanker task, the presence of incongruent flanking
letters increased the number of errors, and also slowed participants’ ability to
identify a central letter. Adolescents committed more errors than adults, but
there were no age-related differences for the reaction time interference effect
in the letter condition. Post-hoc testing revealed that age-related differences
on the task were driven by the younger adolescents (11-14 years); adults and
older adolescents (15-17 years) were equally accurate in the letter condition.
In contrast, on the emotional face flanker task, not only were adolescents less
accurate than adults but they were also more distracted by task-irrelevant
fearful faces as evidenced by greater reaction time interference effects. Our
findings suggest that the ability to self-regulate in adolescents, as evidenced
by the ability to suppress irrelevant information on a flanker task, is more
difficult when stimuli are affective in nature. The ability to ignore irrelevant
flankers appears to mature earlier for non-affective stimuli than for affective
stimuli. 相似文献

How Does Explicit Versus Implicit Risk Information Influence Adolescent Risk‐Taking Engagement? 下载免费PDF全文

Adolescents have been shown to be more likely to engage in risky behaviors in daily life. Many studies have indicated that adolescents could make advantageous choices when they receive explicit information but could fail to choose advantageously when they are not informed about risks. The current study aimed to examine the influence of explicit risk information (i.e., when risk information is directly available) versus implicit risk information (i.e., when risk information has to be learned from feedback) on risk‐taking engagement, in order to clarify whether the enhanced risk‐taking observed in decision making under ambiguity in adolescents results from either a greater exploration of ambiguous situations (i.e., a higher ambiguity tolerance) or a specific difficulty associated with learning based on previous choices' outcomes. Adolescents and young adults completed a new adaptation of the Balloon Analogue Risk Task. They were required to accumulate as many points as possible by inflating balloons associated with variable break points and avoiding explosions. This adaptation involved a manipulation of the information level with two conditions, an “informed” condition and a “noninformed” condition, in which the participants had to learn the matching of colors with balloons' resistances based on feedback. The results demonstrated that providing explicit risk information allows adolescents to be as efficient as adults at the end of the game. In contrast, adolescents failed to adjust risk‐taking to the balloon resistance in the noninformed condition. These findings critically suggest that this failure reflects a specific impairment of feedback‐based learning ability but not a global excess of risk‐taking during adolescence.

The present study aims to develop an integrative model that links neighborhood behavioral opportunities and social resources (neighborhood cohesion, neighborhood friendship and neighborhood attachment) to prosocial (sharing, helping, empathic) behavior in early adolescence, taking into account the potential mediating role of perceived support of friends. Path analysis was used to test the proposed theoretical model in a sample of 1,145 Italian early adolescents (6th through 8th graders). More perceived opportunities and social resources in the neighborhood are related to higher levels of adolescent prosocial behavior, and this relationship is partially mediated by perceived social support from friends. The results offer promising implications for future research and intervention programs that aim to modify social systems to improve child and adolescent social competencies. 相似文献

An integrated analysis of the data from 3 different studies was conducted to examine the early psychosocial predictors of later marijuana use among adolescents. Longitudinal analysis of interview data was performed. The data used in the analysis were derived from (a) a sample of 739 predominantly White adolescents representative of the northeastern United States, (b) a sample of 1,190 minority adolescents from the East Harlem section of New York City, and (c) a sample of 1,374 Colombian adolescents from two cities in Colombia. South America. In 2 of the samples, participants were interviewed in their homes, and in the 3rd study, participants were assessed in school. The predictors included a number of variables from (a) the personality domain, reflecting the adolescents' conventionality and intrapsychic functioning; (b) the family domain, representing the parent-child mutual attachment relationship and parental substance use; (c) the peer domain, reflecting the peer group's delinquency and substance use; and (d) the adolescents' own use of legal drugs. The dependent variable was adolescent marijuana use. The results of the analysis demonstrated remarkable consistency in the risk and protective factors for later marijuana use across the 3 samples, attesting to the robust nature of these predictors and their generalizability across gender, time, location, and ethnic/cultural background. These findings have important implications for designing intervention programs. Programs aimed at preventing adolescent marijuana use can be designed to incorporate universal features and still incorporate specific components that address the unique needs of adolescents from different groups. 相似文献

The Positives and Negatives of Higher Education: How the Religious Context in Adolescence Moderates the Effects of Education on Changes in Religiosity 下载免费PDF全文
Philip Schwadel 《Journal for the scientific study of religion》2017,56(4):869-885
Although longitudinal research suggests that declines in religiosity associated with higher education vary across religious traditions, it tells us little about variation in the effects of higher education on changes in religiosity more broadly. Higher education may promote increases in religiosity for some, particularly with many Americans now being raised in relatively secular homes. This research note uses multilevel growth curve models and four waves of longitudinal data to examine how the religious context in adolescence moderates the effects of higher education on changes in emerging adult religiosity, regardless of the direction of change. Religious tradition and parent religious service attendance assess the religious context in adolescence, and several religiosity scales and measures of religious behaviors assess dimensions of religiosity. Results show that higher education is particularly likely to lead to religious decline for mainline Protestants and those with religiously active parents, and to increases in religiosity for the religiously unaffiliated and those with parents who infrequently attend religious services. These findings demonstrate how the religious context in adolescence conditions the influence of education, thereby highlighting the variable nature of the influence of higher education on changes in religiosity. 相似文献
