Examining the link between adolescent brain development and risk taking from a social–developmental perspective

The adolescent age period is often characterized as a health paradox because it is a time of extensive increases in physical and mental capabilities, yet overall mortality/morbidity rates increase significantly from childhood to adolescence, often due to preventable causes such as risk taking. Asynchrony in developmental time courses between the affective/approach and cognitive control brain systems, as well as the ongoing maturation of neural connectivity are thought to lead to increased vulnerability for risk taking in adolescence. A critical analysis of the frequency of risk taking behaviors, as well as mortality and morbidity rates across the lifespan, however, challenges the hypothesis that the peak of risk taking occurs in middle adolescence when the asynchrony between the different developmental time courses of the affective/approach and cognitive control systems is the largest. In fact, the highest levels of risk taking behaviors, such as alcohol and drug use, often occur among emerging adults (e.g., university/college students), and highlight the role of the social context in predicting risk taking behavior. Moreover, risk taking is not always unregulated or impulsive. Future research should broaden the scope of risk taking to include risks that are relevant to older adults, such as risky financial investing, gambling, and marital infidelity. In addition, a lifespan perspective, with a focus on how associations between neural systems and behavior are moderated by context and trait-level characteristics, and which includes diverse samples (e.g., divorced individuals), will help to address some important limitations in the adolescent brain development and risk taking literature.

The triadic model perspective for the study of adolescent motivated behavior

The triadic neural systems model is a heuristic tool, which was developed with the goal of providing a framework for neuroscience research into motivated behaviors. Unlike dual models that highlight dynamics between approach systems centered on striatal function and control systems centered on prefrontal cortex, the triadic model also includes an avoidance system, centered on amygdala-related circuits. A first application of this model has been to account for adolescent behavior.     

Evidence for spontaneous level-2 perspective taking in adults

Social interactions are fostered by humans’ propensity to compute their partner’s perspective online. However, due to the mindreading system’s limited capacity perspective taking (PT) was argued to occur spontaneously only for level-1, but not level-2 perspectives. We propose that level-2 perspectives (containing aspectual information) can also be computed spontaneously if participants have reason to assume that the partner is indeed aware of the objects’ aspectual properties. Pairs of adult participants took part in the modified version of Surtees, Butterfill, and Apperly’s (2012) number verification paradigm. Participants had prior information on their partner’s task, which either called for processing aspectual properties or did not. The partner’s inconsistent perspective was found to interfere with RT-s providing evidence for spontaneous level-2 PT. However, such interference only occurred when the partner’s task involved processing the perspective dependent object feature, suggesting that PT was sensitive to the other’s awareness of the to be represented information.     

Expressive suppression and financial risk taking: A mediated moderation model

This research aimed to investigate the relationship between the habitual use of expressive suppression, a type of emotion regulation strategy, and risk taking in the financial domain. It also attempted to further examine gender as a possible moderator of this relationship and to explore the anticipated emotion related to negative potential outcomes as the mechanism behind this moderated effect. Two studies were conducted for these purposes. In Study 1, a total of 657 college students completed a test battery, including both the Emotion Regulation Questionnaire and the Grable and Lytton Risk Tolerance Scale. The results showed that expressive suppression was negatively related to financial risk taking, and gender moderated this relationship. In Study 2, 441 college students took a test battery including both the Emotion Regulation Questionnaire and a financial investment allocation task. The results replicated the findings in Study 1 and indicated that the anticipated emotion related to negative potential outcomes fully mediated the moderated effect of gender in the suppression-financial risk taking association. These findings implied the importance of considering gender differences in the prediction of financial choices from the perspective of emotion regulation.     

Cognitive development in children of adolescent mothers: The impact of socioeconomic risk and maternal sensitivity

BackgroundAdolescent motherhood is accompanied by a constellation of risk factors that translate into developmental risk for the off-spring. Socioeconomic risk that is associated with adolescent motherhood as well as maternal interactive behaviors may contribute to the impact of adolescent motherhood on children’s developmental outcome.ObjectiveTherefore, the aim of the current study was to investigate differences in children’s cognitive development between children of adolescent and adult mothers in their first two years of life and to examine whether socioeconomic risk (e.g. such as educational and financial problems) and/or maternal sensitivity mediate developmental differences between children of adolescent and adult mothers.MethodsAdolescent mothers (<21 years; N = 64) and adult mothers (>25 years; N = 34) and their infants were included in the current study. Child cognitive development and maternal sensitivity were assessed at three different time points (T1: mean child age 5.26 months; T2: mean child age 14.69 months; T3: mean child age 21.16 months).ResultsChildren of adult mothers showed better cognitive performance at T3 compared to children of adolescent mothers but not at T1 and T2. A multiple mediation model including socioeconomic risk and maternal sensitivity as serial mediators demonstrated that the effect of adolescent motherhood on cognitive development was mediated in a causal effect chain with socioeconomic risk negatively affecting maternal sensitivity and maternal sensitivity affecting children’s cognitive development.DiscussionThe present findings demonstrate that maternal interactive behaviors are not only a simple predictor of cognitive development but may also act as a mediator of the association between more distal variables such as socioeconomic risk and cognitive development in adolescent mothers. This supports the need to promote prevention and intervention programs for adolescent mothers during the early postpartum period to reduce socioeconomic problems and enhance maternal interactive behaviors.     

Instrumental and disinhibited financial risk taking: Personality and behavioural correlates

Risk taking, including that within the financial domain, is often considered to represent a unidimensional personality trait. This paper considers the relatively unexplored construct of instrumental financial risk taking: a class of behaviours that while inherently risky, are entered into with a greater degree of consideration than more impulsive or disinhibited forms of risk taking. Participants (N = 1043) completed a novel questionnaire assessing instrumental and disinhibited financial risk taking as part of a battery including measures of: sensation-seeking, impulsivity, psychopathic personality traits and real life financial outcomes. Correlations revealed a divergent pattern of relationships supporting the utility of characterising these different forms of financial risk. Scores on the novel instrument are shown to explain more than 10% of the variance in the use of riskier, more productive savings products, over and above the influence of demographics and financial status.     

Global-local processing impacts academic risk taking

Research has shown that academic risk taking—the selection of school tasks with varying difficulty levels—affords important implications for educational outcomes. In two experiments, we explored the role of cognitive processes—specifically, global versus local processing styles—in students’ academic risk-taking tendencies. Participants first read a short passage, which provided the context for their subsequent academic risk-taking decisions. Following which, participants undertook the Navon’s task and attended to either global letters or local letters only, i.e., were either globally or locally primed. The effects of priming on academic risk taking were then assessed using a perception-based measure (Experiment 1) and a task-based measure (Experiment 2). Experiment 1 provided preliminary evidence, which Experiment 2 confirmed, that globally focused individuals took more academic risk than did locally focused individuals after controlling for participants’ need for cognition (how much they enjoy effortful cognitive activities). Additionally, the inclusion of and comparisons with a control group in Experiment 2 revealed that locally focused participants drove the observed effects. The theory of predictive and reactive control systems (PARCS) provides a cogent account of our findings. Future directions and practical applications in education are discussed.     

Knowing minds: Linking early perspective taking and later metacognitive insight

Recent metacognitive research using a partial knowledge task indicates that a firm understanding of ‘knowing about knowing’ develops surprisingly late, at around 6 years of age. To reveal the mechanisms subserving this development, the partial knowledge task was used in a longitudinal study with 67 children (33 girls) as an outcome measure at 5;9 (years;months). In addition, first- and second-order false belief was assessed at 4;2, 5;0, and 5;9. At 2;6, perspective taking and executive abilities were evaluated. Metacognition at 5;9 was correlated with earlier theory of mind and perspective taking – even when verbal intelligence and executive abilities were partialled out. This highlights the importance of perspective taking for the development of an understanding of one’s own mind.

Generalized others and imaginary audiences: A neo-Meadian approach to adolescent egocentrism

Piaget’s conception of adolescent egocentrism, as interpreted and extended by Elkind (1967) is discussed, and research that has related Elkind’s egocentric ideations of personal fable and imaginary audience to age and intellectual development is considered. Alternative theories of adolescent egocentrism and its decentration are examined, and a neo-Meadian framework is discussed that understands the imaginary audience ideation of adolescents as a possibly functional, highly variable response to the complex task of coordinating individual and social perspectives as part of the adolescent’s search for identity.     

A social neuroscience perspective on adolescent risk-taking

This article proposes a framework for theory and research on risk-taking that is informed by developmental neuroscience. Two fundamental questions motivate this review. First, why does risk-taking increase between childhood and adolescence? Second, why does risk-taking decline between adolescence and adulthood? Risk-taking increases between childhood and adolescence as a result of changes around the time of puberty in the brain’s socio-emotional system leading to increased reward-seeking, especially in the presence of peers, fueled mainly by a dramatic remodeling of the brain’s dopaminergic system. Risk-taking declines between adolescence and adulthood because of changes in the brain’s cognitive control system—changes which improve individuals’ capacity for self-regulation. These changes occur across adolescence and young adulthood and are seen in structural and functional changes within the prefrontal cortex and its connections to other brain regions. The differing timetables of these changes make mid-adolescence a time of heightened vulnerability to risky and reckless behavior.     

视觉观点采择中自我中心性偏差的抑制和归因之争

自我中心性偏差是社交失败的重要原因,但其产生机制还存在争议。以往研究存在抑制性选择模型与流利性错误归因两种理论观点:前者认为对自身观点的抑制失败会导致自我中心性偏差;后者则认为错误地选择自身更为流畅的信息会导致自我中心性偏差。为整合上述争论,提出抑制-归因协同作用模型,认为抑制和归因两种加工或可共同导致自我中心性偏差。未来研究应借助精巧的研究范式和特殊被试群体,进一步验证该模型。     

急性应激与风险倾向：兴奋易感性的调节作用

为探索应激对决策的作用机理及其个体差异,减少工程作业中因应激导致的决策失误,本研究采用特里尔社会应激测试和气球模拟风险任务考察应激反应与应激下风险倾向的关系,并探索兴奋易感性在其中的调节作用。研究结果表明,应激下个体的皮质醇反应越大,行为越冒险。且这一作用受到兴奋易感性的调节：兴奋易感性较高的个体,应激下皮质醇反应越大,行为越冒险;而兴奋易感性较低的个体,其皮质醇变化不能预测风险倾向。该发现提示了兴奋易感性在应激影响中的重要作用,也为高压岗位的人员选拔提供了科学启示。     

A dual-process approach to health risk decision making: The prototype willingness model

Although dual-process models in cognitive, personality, and social psychology have stimulated a large body of research about analytic and heuristic modes of decision making, these models have seldom been applied to the study of adolescent risk behaviors. In addition, the developmental course of these two kinds of information processing, and their relation to the development of self-regulation are not well understood at this time. The current paper reviews what leading dual-process models have to say about the development of analytic and heuristic decision making, and their implications for adolescent risk behavior. In addition, it reviews research on the prototype willingness model of adolescent decision making—a dual-process model designed specifically to address non-intentional, but volitional adolescent risk behavior. It also discusses the implications of dual-process models for intervention research.

Honesty‐humility and prosocial behavior: The mediating roles of perspective taking and guilt‐proneness

The prosocial personality trait of honesty‐humility has received extensive attention in the last decade. However, research on the mechanism underlying the relationship between honesty‐humility and prosocial behavior is rather scarce. This study aims to explore the internal mechanism underlying this relationship to draw a complete picture of the honesty‐humility trait. A sample of 458 Chinese young adults was obtained to complete self‐report measures of honesty‐humility, perspective taking, guilt‐proneness, and prosocial behavior. The mediation model revealed that: (1) honesty‐humility positively related to prosocial behavior; (2) perspective taking and guilt‐proneness mediated the relationship between honesty‐humility and prosocial behavior, separately; and (3) the effect of honesty‐humility on prosocial behavior was mediated via perspective taking and then guilt‐proneness. In conclusion, we provide an initial support for the mediating roles of perspective taking and guilt‐proneness in the relationship between honesty‐humility and prosocial behavior. Both theoretical and practical implications for understanding the psychological mechanisms of prosocial behavior are discussed.     

Pricing risk and ambiguity: The effect of perspective taking

In the valuation of uncertain prospects, a difference is often observed between selling and buying perspectives. This paper distinguishes between risk (known probabilities) and ambiguity (unknown probabilities) in decisions under uncertainty and shows that the valuation disparity increases under ambiguity compared to risk. It is found that both the comparative versus noncomparative evaluation of risky and ambiguous prospects and the uniqueness of the valuation perspective (either seller or buyer) moderate this increase in the disparity under ambiguity. The finding is consistent with recent theoretical accounts of pricing under uncertainty. We discuss implications for market behaviour and for the ambiguity paradigm as a research tool.
