Abstract
Cosmetic surgery is ever more affordable and accessible, but carries physical and psychological risks. Yet, no study to date has directly examined risk-taking behaviour under controlled conditions, beyond self-report and in relation to cosmetic surgery attitudes. We used the Balloon Analogue Risk Task and advanced computational modelling to measure decision-making behaviour and identify the latent parameters driving behaviour associated with cosmetic surgery attitudes in women with no cosmetic surgery history (N = 265) and a subsample of women with a cosmetic surgery history (N = 24). Risk taking was higher in women with greater acceptance and history of cosmetic surgery. Computational modelling revealed increased risk taking in women with greater acceptance of cosmetic surgery when decisions were made with greater knowledge of loss (risk) and not when the likelihood of loss was unknown (uncertainty). When women with greater acceptance of cosmetic surgery made decisions, they also placed less emphasis on possible losses (reduced loss aversion). Our findings suggest that women seeking cosmetic procedures may be less sensitive to losses and thus make more risky decisions. Greater emphasis should be placed on communicating potential losses rather than just the associated risks to women considering cosmetic procedures.No Level Assigned This journal requires that authors assign a level of evidence to each submission to which Evidence-Based Medicine rankings are applicable.

Abstract
In a fundamentally uncertain world, sound information processing is a prerequisite for effective behavior. Given that information processing is subject to inevitable cognitive imprecision, decision makers should adapt to this imprecision and to the resulting epistemic uncertainty when taking risks. We tested this metacognitive ability in two experiments in which participants estimated the expected value of different number distributions from sequential samples and then bet on their own estimation accuracy. Results show that estimates were imprecise, and this imprecision increased with higher distributional standard deviations. Importantly, participants adapted their risk-taking behavior to this imprecision and hence deviated from the predictions of Bayesian models of uncertainty that assume perfect integration of information. To explain these results, we developed a computational model that combines Bayesian updating with a metacognitive awareness of cognitive imprecision in the integration of information. Modeling results were robust to the inclusion of an empirical measure of participants' perceived variability. In sum, we show that cognitive imprecision is crucial to understanding risk taking in decisions from experience. The results further demonstrate the importance of metacognitive awareness as a cognitive building block for adaptive behavior under (partial) uncertainty.

Abstract
This paper describes data collected from a cross-sectional convenience sample of 200 healthy human volunteers between 16 and 81 years of age. We assembled an extensive battery of measures of risk preference, impulsivity, and self-control, as well as a range of demographic and cognitive measures, Crucially, we adopted different measure categories, including self-reports, informant reports, behavioral measures, and biological measures (hormones, brain function) to capture individual differences, and adopted a within-participant design. Data collection took place over multiple sessions. First, participants completed a laboratory session at the university during which we collected computer-assisted self-report measures (i.e., standardized questionnaires) as well as behavioral measures using computerized tasks. Second, participants independently completed a home session that included the completion of self-report measures, and the collection of saliva samples. In parallel, we acquired informant reports from up to three individuals nominated by the study participants. Third, participants completed a final session at the local hospital during which we collected structural and functional neuroimaging data, as well as further self-report measures. The data was collected to address questions concerning the developmental trajectories of risk preference and related constructs while assessing the impact of the assessment method; however, we invite fellow researchers to benefit from and further explore the data for research on decision-making under risk and uncertainty in general, and to apply novel analytical approaches (e.g., machine-learning applications to the neuroimaging data). Combining a large set of measures with a within-participant design affords a wealth of opportunities for further insights and a more robust evidence base supporting current theorizing on (age-related) differences in risk preference, impulsivity, and self-control.

Abstract
Adolescents' peer world is highly dynamic with constant dissolution of old friendships and formation of new ones. Though many of adolescents' risky decisions involve their peers, little is known about how adolescents' ever-changing friendships shape their ability to make these peer-involving risky decisions, particularly adaptive ones, and whether this association shifts over time. In a 5-wave longitudinal fMRI study, 173 adolescents (at wave 1: Mage = 12.8, SDage = 0.52; range = 11.9-14.5) made risky choices to win money for their best friend. We assessed whether participants nominated the same or different best friend as their previous participation year (a total of 340 data points of friendship maintenance / change). In early adolescence, adolescents with the same best friend took more adaptive risks for that best friend than those with a different best friend. In late adolescence, however, adolescents with a different best friend took more adaptive risks for the new best friend than those with the same best friend. Further, the amygdala was differentially sensitive to friendship maintenance / change during these peer-involving adaptive risks across time. This study has implications for how stable and flexible peer landscapes differentially modulate social motivation and social decision-making over the course of adolescence.

Abstract
Research on self-reported risk perception and risk taking suggests age-related decrements in risk preference, with older adults less likely to engage in general and domain-specific risk taking (i.e., in financial, health-related, ethical, career, and leisure contexts). Data relating to social risks, however, are inconsistent. With respect to behavioral risk-taking tasks, age-related differences vary depending on task characteristics and older adults' cognitive capacities. Specifically, older adults are less good at learning to take advantageous risks and take fewer risks when faced with gains, especially financial and mortality-based ones. We contextualize these trends by referencing relevant theoretical frameworks (see Frey et al., 2021 [1]) and by drawing on the COVID-19 pandemic to illustrate recent examples of age-related differences in real-life risk responses.

Abstract
BACKGROUND The risk preference during decision-making and the neural substrates involved in patients with obsessive-compulsive disorder (OCD) remained unclear. The current study was designed to evaluate the risk-taking behaviors during decision-making and neural correlates in patients with OCD, thereby providing a deeper insight into their impaired decision-making function. METHODS Fifty-one patients with OCD and 50 healthy controls (HCs) were included in this study. All subjects underwent functional magnetic resonance imaging (fMRI) scans while completing the Balloon Analog Risk Task (BART). The behavior indicator and cognitive model parameter in BART, as well as the neural correlates of risk-taking behaviors were analyzed. RESULTS Compared to HCs, the OCD group performed a significantly higher level of risk-averse behaviors, and the cognitive model parameter revealed that patients with OCD tend to decrease their risk level after receiving negative feedbacks during BART. The fMRI results based on prespecified brain regions showed that the OCD group exhibited significantly decreased activation modulated by risk levels both in the left and right insula. LIMITATIONS The effect of medication in this study could not be completely ruled out, and it is difficult to temporally separate different states of decision-making in the BART. CONCLUSIONS Individuals with OCD exhibited a higher level of risk aversion during decision-making process, and the dysfunction of the insula may be the neural basis of the increased risk aversion in OCD. These findings provide further insights into the mechanism of risk aversion and impaired decision-making function in individuals with OCD.

Abstract
BACKGROUND While many studies from sub-Saharan countries, including Zimbabwe, allude to the important role of religion and tradition for young people living with HIV (YPLHIV), most of these studies tend to be descriptive and lack advanced statistical analysis. This study aims to close this gap. METHODS Data for this study was collected between July and October 2021 from 804 YPLHIV (aged 14-24) in Zimbabwe. The questionnaire included questions regarding participants' conceptions of HIV, their health seeking and risk-taking behaviour, current HIV viral load results, the prevalence of opportunistic infections, their mental health status, and demographic characteristics. The analysis was done using multilevel mixed-effects logistic regression. RESULTS We found that Traditional religious affiliation was linked to overall lower viral load (OR: 0.34; CI: 0.12-0.96; P: 0.042), Apostolic to more (OR: 1.52; CI: 1-2.3; P: 0.049) and Pentecostal to less (OR: 0.53; CI: 0.32-0.95; P: 0.033) treatment failure. Additionally, conceptions about HIV without spiritual or religious connotation, such as 'seeing HIV as result of a weak body' was associated with lower risk of treatment failure (OR: 0.6; CI: 0.4-1.0; P: 0.063), higher chances for undetectable viral load (OR: 1.4; CI: 1-2; P: 0.061), and overall lower viral load (OR: 0.7; CI: 0.5-1; P: 0.067). Moralizing concepts of HIV, like 'seeing HIV as a result of sin in the family', was linked to higher risk of opportunistic infections (OR:1.8; CI:1.1-3; P: 0.018), and higher risk of treatment failure (OR: 1.7; CI: 0.7-1.1; P: 0.066). Religious objections toward certain forms of therapy, like toward cervical cancer screening, was linked to higher risk of mental problems (OR: 2.2; CI: 1.35-3.68; P: 0.002) and higher risk of opportunistic infections (OR:1.6; CI:1.1-2.1; P: 0.008). Religious affiliations significantly influenced conceptions of HIV, health seeking behaviour, and risk taking. CONCLUSION To our knowledge, this study is the first to provide evidence about the statistically significant associations between religious and traditional beliefs and practices and current health outcomes and health risk factors of YPLHIV in Zimbabwe. It is also the first to identify empirically the role of religious affiliations as predictors of current viral load results. This new knowledge can inform contextualized approaches to support YPLHIV in Zimbabwe.

Abstract
Higher executive control capacity allows people to appropriately evaluate risk and avoid both excessive risk aversion and excessive risk-taking. The neural mechanisms underlying this relationship between executive function and risk taking are still unknown. We used voxel-based morphometry (VBM) analysis combined with resting-state functional connectivity (rs-FC) to evaluate how one component of executive function, model-based learning, relates to risk taking. We measured individuals' use of the model-based learning system with the two-step task, and risk taking with the Balloon Analogue Risk Task. Behavioral results indicated that risk taking was positively correlated with the model-based weighting parameter ω. The VBM results showed a positive association between model-based learning and gray matter volume in the right cerebellum (RCere) and left inferior parietal lobule (LIPL). Functional connectivity results suggested that the coupling between RCere and the left caudate (LCAU) was correlated with both model-based learning and risk taking. Mediation analysis indicated that RCere-LCAU functional connectivity completely mediated the effect of model-based learning on risk taking. These results indicate that learners who favor model-based strategies also engage in more appropriate risky behaviors through interactions between reward-based learning, error-based learning and executive control subserved by a caudate, cerebellar and parietal network.

Abstract
Variation in reward responsiveness has been linked to psychopathology. Reward responsiveness is a complex phenomenon that encompasses different temporal dimensions (i.e., reward anticipation or consumption) that can be measured using multiple appetitive stimuli. Furthermore, distinct measures, such as neural and self-report measures, reflect related but distinct aspects of reward responsiveness. To understand reward responsiveness more comprehensively and better identify deficits in reward responsiveness implicated in psychopathology, we examined ways multiple measures of reward responsiveness jointly contribute to distinct psychological problems by using latent profile analysis. Specifically, we identified three profiles of reward responsiveness among 139 female participants based on their neural responses to money, food, social acceptance, and erotic images and self-reported responsiveness to reward anticipation and consumption. Profile 1 (n = 30) exhibited blunted neural responses to social rewards and erotic images, low self-reported reward responsiveness, but average neural responses to monetary and food rewards. Profile 2 (n = 71) showed elevated neural response to monetary rewards, average neural responses to other stimuli, and average self-reported reward responsiveness. Profile 3 (n = 38) showed more variable neural responses to reward (e.g., hypersensitivity to erotic images, hyposensitivity to monetary rewards), and high self-reported reward responsiveness. These profiles were differentially associated with variables generally linked to aberrations in reward responsiveness. For example, Profile 1 was most strongly associated with anhedonic depression and social dysfunction, whereas Profile 3 was associated with risk-taking behaviors. These preliminary findings may help to elucidate ways different measures of reward responsiveness manifest within and across individuals and identify specific vulnerabilities for distinct psychological problems.

Abstract
Social and neurobiological factors independently associate with the development of antisocial behavior during adolescence, yet it is unclear how these factors contribute to antisocial behavior in girls. Using a longitudinal sample of 45 adolescent girls (age in years at scan: M = 15.38, SD = 0.33), this study examined the contributions of parent-adolescent relationship quality and deviant peer affiliation from 6th-8th grades along with the neural correlates of risk taking in 9th grade to later antisocial behavior. High parent-adolescent closeness in early adolescence predicted lower antisocial behavior for girls in later adolescence via lower affiliation with deviant peer groups and less activation of the medial prefrontal cortex during risk taking. Findings highlight the enduring role of parents and peers during adolescence, and the importance of investigating social relationships alongside the brain to identify a holistic understanding of the development of antisocial behavior in girls.

Abstract
OBJECTIVES How does risk preference change across the life span? We address this question by conducting a coordinated analysis to obtain the first meta-analytic estimates of adult longitudinal age differences in risk-taking propensity in different domains. METHODS We report results from 26 longitudinal samples (12 panels; 187,733 unique respondents; 19 countries) covering general and domain-specific risk-taking propensity (financial, driving, recreational, occupational, health) across 3 or more waves. RESULTS Results revealed a negative relation between age and both general and domain-specific risk-taking propensity. Furthermore, females consistently reported lower levels of risk taking across the life span than males in all domains, but there is little support for the idea of an age by gender interaction. Although we found evidence of systematic and universal age differences, we also detected considerable heterogeneity across domains and samples. DISCUSSION Our work suggests a need to understand the nature of heterogeneity of age differences in risk-taking propensity and recommends the use of domain-specific and population estimates for applications interested in modeling heterogeneity in risk preference for economic and policy-making purposes.

Abstract
Risk taking is more commonly shown by males than females and has a signalling function, serving to advertise one's intrinsic quality to prospective mates. Previous research has established that male risk takers are judged as more attractive for short-term flings than long-term relationships, but the environmental and socioeconomic context surrounding female preferences for male risk takers has been overlooked. Using a survey instrument, we examined female preferences for male risk takers across 1304 females from 47 countries. We found preferences for physical risk takers to be more pronounced in females with a bisexual orientation and females who scored high on risk proneness. Self-reported health was positively associated with preferences for high risk takers as short-term mates, but the effect was moderated by country-level health, i.e. the association was stronger in countries with poorer health. The security provided by better health and access to health care may allow females to capitalise on the genetic quality afforded by selecting a risk-prone male whilst concurrently buffering the potential costs associated with the risk taker's lower paternal investment. The risk of contracting COVID-19 did not predict avoidance of risk takers, perhaps because this environmental cue is too novel to have moulded our behavioural preferences.

Abstract
INTRODUCTION People with cerebellar ataxia (CA) can develop impulsive and compulsive behaviors that significantly affect their and their family's quality of life. To further assess the decision-making process associated with these behaviors, we used the Iowa Gambling Task (IGT) to study people with CA. METHODS Sixty individuals with CA and thirty age-matched controls were enrolled in the study to complete the IGT. No participants had a prior or comorbid neurologic or psychiatric disorder associated with impulsivity. IGT performance in each of the five 20-trial blocks was compared between groups and the progression of participants' performance was assessed with simple linear regression models. Subgroup analyses were performed with genetic and non-genetic CA cases. RESULTS CA cases obtained significantly lower IGT total scores than controls (-5.30 ± 37.53 vs. 21.30 ± 37.37, p = 0.004). In addition, those with CA made riskier decisions throughout the task compared to controls. Although both CA and controls learned to make decisions with more favorable outcomes over the course of completing the IGT, CA participants never matched the controls' performance. IGT performance did not correlate with ataxia severity or depressive symptoms. CONCLUSION The IGT may capture a unique behavioral symptom of CA. Future studies may help elucidate the mechanisms underlying impaired decision-making in CA and further the understanding of a broader spectrum of cerebellar cognitive affective syndrome.

Abstract
OBJECTIVES The present study sought to explore how decision making is influenced by aging, framing, and social distance in the medical domain. Based on Socioemotional Selectivity Theory, we predicted that social distance would moderate age differences of framing effects as a result of older adults' emphasis on close partners. METHODS Younger and middle-aged (N = 206) and older (N = 208) adults from Shanghai, China completed 2 medical decision tasks in which they were presented with different descriptions of social distance, namely deciding for close relatives or for strangers. Participants' risk preferences were measured. RESULTS The results showed that framing effects were a function of social distance in older adults. Older adults showed smaller framing effects when making decisions for strangers as their preference for the riskier option was reduced in the loss-framed condition. For younger and middle-aged adults, framing effects existed consistently regardless of social distance. DISCUSSION These findings suggest that social distance moderates age differences in framing effects in medical decision-making. It also highlights a potential way to improve older adults' medical decision-making quality: having older adults imagine as if they are making medical decisions for a stranger.

Abstract
This study identifies the influence of interdisciplinary variables on tourist online purchasing intention, such as consumers' online purchasing experience, novelty-seeking behavior, perceived ease of use, risk taking, tourism service and destination characteristics. The study population includes international tourists who purchased Yazd sightseeing tours. Using convenience sampling, 386 visitors were chosen to complete the variable scale questionnaire. The data were analyzed using SmartPLS and SPSS software. Results indicated that "prior experience," "ease of use," "risk taking", and "novelty-seeking behavior" have a direct and meaningful effect on "online purchasing attitude" and have an indirect effect on "tourist online purchasing intention" with the mediating role of online purchasing attitudes. Furthermore, "tourism services and destination characteristics" and online purchasing attitudes directly and significantly affect tourists' online purchasing intentions. Moving between disciplines improves the quality of industry-relevant research and makes it more practical and valuable. The identified interdisciplinary variables influencing tourists' online purchasing intentions are valuable for the destination marketing of World Heritage Cities.

Abstract
Adolescent decision-making has been characterized as risky, and a heightened reward sensitivity may be one of the aspects contributing to riskier choice-behavior. Previous studies have targeted reward-sensitivity in adolescence and the neurobiological mechanisms of reward processing in the adolescent brain. In recent examples, researchers aim to disentangle the contributions of risk- and reward-sensitivity to adolescent risk-taking. Here, we discuss recent findings of adolescent's risk preferences and the associated neural mechanisms. We highlight potential frameworks that target individual differences in risk preferences in an effort to understand adolescent risk-taking, and with an ultimate goal of leveraging undesirable levels of risk taking.

Abstract
We examine the immediate impact of COVID-19 on the performance of FDIC chartered banks. Our experimental design analyses the performance of community banks and large banks before and during the COVID-19 pandemic. Community banks significantly outperform large banks in several key measures in the first three-quarters of COVID-19. Findings are consistent with the view that the advantages of solid customer relationships and a greater understanding of local businesses are invaluable during periods of high externalities. This result is more pronounced for community banks located in metropolitan areas. We also find that the pandemic's adverse effects on bank performance are minimized in states with higher quality healthcare facilities, as measured by our healthcare index. In addition, the performance of community banks varies across geographical regions during this pandemic period. Finally, our study expands the understanding of how community banks' performance and risk-taking change during a pandemic.

Abstract
Exploring ones surroundings may yield unexpected rewards, but is associated with uncertainty and risk. Alternatively, exploitation of certain outcomes is related to low risk, yet potentially better outcomes remain unexamined. As such, risk-taking behavior depends on perceived uncertainty and a trade-off between exploration-exploitation. Previously, it has been suggested that risk-taking may relate to theta activity in the prefrontal cortex. Furthermore, previous studies hinted at a relationship between a right-hemispheric bias in frontal theta asymmetry and risky behavior. In the present double-blind sham-controlled within-subject study, we applied bifrontal transcranial alternating current stimulation (tACS) at the theta frequency (5 Hz) on eighteen healthy volunteers during a gambling task. Two tACS montages with either left-right or posterior-anterior current flow were employed at an intensity of 1 mA. Results showed that, compared to sham, theta tACS increased perceived uncertainty irrespective of current flow direction. Despite this observation, no direct effect of tACS on exploration behavior and general risk-taking was observed. Furthermore, frontal theta asymmetry was more right-hemispherically biased after posterior-anterior tACS, compared to sham. Finally, we used electric field simulation to identify which regions were targeted by the tACS montages as an overlap in regions may explain why the two montages resulted in comparable outcomes. Our findings provide a first step towards understanding the relationship between frontal theta oscillations and different features of risk-taking.

Abstract
Businesses are gradually reopening as lockdown measures for the coronavirus disease 2019 (COVID-19) pandemic are being relieved in many places across the globe. It is challenging but imperative for businesses to manage the risk of infection in the workplace and reopen safely. Drawing on risky decision-making theory and the job demands-resource model of workplace safety, we examined the influences of employees' COVID-19 risk perception on their safety performance at work. On the one hand, COVID-19 risk perception motivates employees to perform safely; on the other hand, COVID-19 risk perception could also undermine safety performance through triggering anxiety. In an effort to find ways that alleviate the negative implications of risk perception, we also tested a cross-level interaction model where the risk perception-anxiety relation is weakened with a favorable team safety climate as well as low abusive supervision. Our data were collected from car dealership employees located in China in March 2020, when businesses just started to reopen in locations where these data were collected. Results showed that COVID-19 risk perception was positively related to anxiety, which in turn undermined safety performance. This negative effect canceled out the direct positive effects of COVID-19 risk perception on safety performance. In addition, cross-level interaction results showed that the buffering effect of team safety climate on the risk perception-anxiety relation was diminished with an abusive supervisor. Our findings provide valuable and timely implications on risk management and workplace safety during a public health crisis such as the COVID-19 pandemic.

Abstract
The willingness to take a risk is shaped by temperaments and cognitive abilities, both of which develop rapidly during childhood. In the adult developmental literature, a distinction is drawn between description-based tasks, which provide explicit choice-reward information, and experience-based tasks, which require decisions from past experience, each emphasizing different cognitive demands. Although developmental trends have been investigated for both types of decisions, few studies have compared description-based and experience-based decision making in the same sample of children. In the current study, children (N = 112; 5-9 years of age) completed both description-based and experience-based decision tasks tailored for use with young children. Child temperament was reported by the children's primary teacher. Behavioral measures suggested that the willingness to take a risk in a description-based task increased with age, whereas it decreased in an experience-based task. However, computational modeling alongside further inspection of the behavioral data suggested that these opposite developmental trends across the two types of tasks both were associated with related capacities: older (vs. younger) children's higher sensitivity to experienced losses and higher outcome sensitivity to described rewards and losses. From the temperamental characteristics, higher attentional focusing was linked with a higher learning rate on the experience-based task and a bias to accept gambles in the gain domain on the description-based task. Our findings demonstrate the importance of comparing children's behavior across qualitatively different tasks rather than studying a single behavior in isolation.

Abstract
Car traffic and accidents involving cars create an enormous societal cost, particularly in terms of negative consequences for public health. Mitigating these effects is a daily concern for public and private institutions and people around the world. At least a subset of accidents is attributable to the amount of risk drivers allow in their driving and in related behaviour like mobile phone use or substance abuse. Our study looks at the effect of car size on risk taking. While literature highlights several behavioural effects of car size, the direction of causality of these effects is not always clear, and empirical evidence is lacking. Two behavioural and consequential studies support that car size affects risk taking in driving and that this increase in risk taking generalizes to other domains as well. Based on these results and in line with literature showing that social stability and security can affect financial risk taking, we propose the "car cushion hypothesis." This hypothesis suggests that bigger cars make people feel more secure, which affects their behaviour in terms of generalized risk taking. We discuss policy implications aimed at contributing to reducing the societal and public health cost of car traffic.

Abstract
Individual variation in cognition, seen in many taxa, is not well understood, despite its potential evolutionary consequences. Inhibitory control is an aspect of cognition which differs between individuals. However, how selection could act on this variation remains unclear. First, individual consistency over time of behaviours affected by inhibitory control, and how these behaviours relate to each other, is not well understood. Second, consequences in ecologically relevant contexts of variation in behaviours affected by inhibitory control, are scarcely investigated. Therefore, we explored the temporal consistency and inter-relatedness of two behaviours influenced by inhibitory control (impulsive action and persistence) and how these link to social rank, foraging efficiency, and risk taking in adult female red junglefowl (Gallus gallus). We measured impulsive action in a detour test, and persistence in both a detour test and a foraging test. Impulsive action and persistence, measured in a detour test, were moderately consistent over time, and positively correlated. This implies that selection could act on inhibitory control via these behaviours, and selection on one behaviour could affect the other. However, we found no evidence of links between inhibitory control and social rank, foraging efficiency, or risk taking. This implies that selection may not act on inhibitory control via these measures, and that, in general, there may be a lack of strong selection on inhibitory control. This, in turn, could help explain individual variation in this aspect of cognition. Future research should explore the specificity of when inhibitory control has implications for individuals, and continue to investigate how variation in cognitive traits influences how individuals behave in contexts with potential evolutionary implications.

Collected information was socio-demographic characteristics of the respondents, riding experience, formal training, possession of valid drivers' licence, motorcycle ownership status, mobile phone usage, history of crash in the previous one year, riding hours per day, helmet use, carrying more than one passenger, riding against traffic and daily income. Results The study were enrolled 502 individuals with a mean age of 31.5±8.7. The ratio of men to women was 250:1. All respondents who admitted to engage in the study had at least one risky behaviour in the past (95.4% admitted to transporting one passenger more than the legal) and 56.6% admit to a prior history of traffic offences. The crashes' predictive factors include respondent age, cell phone use while riding, prior traffic offences, carrying more than one pillion rider, use of stimulants such as kolanut and bitter kola, alcohol drink riding, and admission of fault in the prior of crashes. Conclusion Commercial motorcyclists in Owo, Ondo State Nigeria engaged in risky behaviours that raised their likelihood of being involved in crashes. The objectives of public enlightenment and driver education at these behaviours could help to reduce the occurrence of crashes among them.

Abstract
Previous research has demonstrated that individuals present increased risk taking at the end of a series of gambles, a phenomenon called the ending effect. By using a large online football gambling data, we attempted to replicate the ending effect and tested the existence of a different pattern of increased risk taking at the ending. The results showed that at the end of a series of football gambles, bettors would take more risks, and options with lower risk would be preferred. In games without the interference of local bettors, the ending effect was found to be stronger than that of games with local bettors. Overall, the results provide evidence for the bounded ending effect. Possible underlying mechanisms of the bounded ending effect are explored.

Abstract
Attention-deficit/hyperactivity disorder (ADHD) is often accompanied by excessive risky behavior, and an impulsive trait has been proposed to be associated with risk-taking. However, the aspect of the cognitive process that impulsivity influences is not well understood. We hypothesized that impulsivity could be related to an overhasty shifting of beliefs during risk learning, thereby resulting in enhanced risk-taking behavior. In this study, we tested our hypothesis using the Bayesian modeling approach and predicted overhasty learning by a data-driven approach. We used an openly available task-based functional magnetic resonance imaging (fMRI) dataset. Participants with adult ADHD (n = 42) completed the balloon analog risk task (BART). By fitting our computational model that encapsulates the degree of overhasty learning, we estimated the degree of learning bias and investigated its relationship with Barratt Impulsiveness Scale (BIS) outcomes. Moreover, we created a connectome-based predictive model (CPM) based on fMRI data to predict the degree of risk-learning bias. The degree of overhasty learning in ADHD patients was significantly correlated with the BIS score (r = 0.424, p = 0.009). The CPM predicted the 'learning bias' parameter using negatively correlated edges (r = 0.341, p = 0.041; q2 = 0.092). The 'hub nodes' in the predictive network were in the frontal lobe, including the orbitofrontal area. Our findings suggest that impulsivity in ADHD patients is associated with overhasty updating of beliefs during risk learning. Weak functional connectivity to the both dorso-lateral prefrontal and orbitofrontal lobes is predictive of the degree of overhasty learning.

Abstract
BACKGROUND Excessive risk taking is a characteristic trait of several psychiatric conditions, including substance use disorders. High risk-taking (HiR) rats self-administer more cocaine compared to low risk-taking (LoR) rats. However, research has not determined if risk taking is associated with enhanced cocaine conditioned place preference (CPP). METHODS Male and female Sprague Dawley rats (n = 48 each sex) were first tested in the risky decision task (RDT), in which a response on one lever resulted in safe delivery of one food pellet, and a response on a different lever resulted in delivery of two pellets and probabilistic delivery of foot shock. Following RDT training, rats were tested for cocaine CPP. The first session was a pretest that measured rats' preference for three compartments that provided different visual and tactile cues. Rats then learned to associate one compartment with cocaine (either 10.0 mg/kg or 20.0 mg/kg; i.p.) and one compartment with saline (1.0 ml/kg; i.p.) across eight conditioning sessions. Finally, rats explored all three compartments in a drug-free state. RESULTS Sex significantly moderated the association between risky decision making and cocaine CPP. While increased risk aversion was somewhat positively associated with cocaine CPP in males, increased risk taking was positively correlated with cocaine CPP in females. CONCLUSIONS These results highlight the moderating role of sex on the relationship between risky decision making and cocaine reward.

Abstract
BACKGROUND According to Fuzzy-Trace Theory (FTT), qualitative, bottom-line, "gist" reasoning leads to less risk taking and more mature decision-making, less easily swayed by emotions than quantitative, detail-oriented, "verbatim" reasoning. In Bipolar disorder deleterious risky behaviors are common. Prior research confirmed the relationships posited between FTT and risk taking. We aim to understand whether FTT acts upon risk taking in the manner proposed in the FTT framework, namely, that (a) gist "values" mediate the role of "categorical gist". Furthermore, the roles of mania and impulsivity, cited as factors for risk-taking, remain to be clarified. In this study, we investigate if (b) manic symptoms and impulsivity moderate these relationships. METHODS Participants (N = 105) completed an online survey including demographics, clinical variables, symptomatology, FTT, risk taking and risk perception. RESULTS Mediational models indicated that (a) Gist Values mediated Categorical Gist's effect on risk taking, as expected by the FTT framework. (b) Impulsivity moderates risk taking, but manic-type symptomatology does not. LIMITATIONS Voluntary, self-report surveys may have low participant motivation and limit the diagnostic validity and the inpatient generalizability of the results. CONCLUSIONS The results move beyond a focus on mood-related aspects of Bipolar disorder and confirm the importance of understanding reasoning processes like FTT in combination with impulsivity, as potential behavioral factors of risk taking in Bipolar disorder. The clarifications on FTT's functioning as a mechanism prescribe possible openings for more efficacious reduction of risky behaviors through behavioral interventions focusing on value creation.

Abstract
Adolescents with Attention-Deficit/Hyperactivity Disorder (ADHD) demonstrate increased levels of real-life risk-taking behavior like substance abuse and reckless behavior in traffic, which potentially originates in decision-making deficits. Using experimental gambling tasks, the current study investigated three potential underlying mechanisms: (1) risky vs. suboptimal decision making, (2) the complexity of decision-making strategies and (3) the influence of feedback. Participants were 181 male adolescents (81 ADHD, 100 Typically Developing (TD); Mage = 15.1 years). First, we addressed a common confound in many gambling tasks by disentangling risk seeking from suboptimal decision making, and found that ADHD-related decision-making deficits do not originate in increased risk seeking but in suboptimal decision making. Second, we assessed decision-making strategies with a Bayesian latent mixture analysis and found that ADHD-related decision-making deficits are characterized by the use of less complex strategies. That is, adolescent boys with ADHD, relative to TD adolescent boys, less often adopted strategies in which all characteristics relevant to make an optimal decision were integrated. Third, we administered two gambling task conditions with feedback in which adolescents experience the outcomes of their decisions and found that adolescents with ADHD performed worse relative to TD adolescents on both conditions. Altogether, this set of studies demonstrated consistent decision-making deficits in adolescent boys with ADHD: The use of less complex decision-making strategies may cause suboptimal decision making, both in situations with and without direct feedback on performance.

Abstract
BACKGROUND In the fields of psychology and psychiatry, the use of the terms impulsivity, sensation-seeking and ordalie to refer to risk-taking behaviors can sometimes be confusing. OBJECTIVE The objective of this study was to establish a clinical definition of the concepts of ordalie, sensation-seeking and impulsivity, in order to analyze the similarities and differences between these concepts. METHODS We prioritized literature review articles with or without meta-analysis from the Medline database and supplemented with the Google-Scholar database. The articles were included in this review if their objectives were in line with ours. The research was conducted in November 2018. RESULTS Twenty-seven articles were selected. There are similarities in the clinical definitions of these concepts with measurable heterogeneous constructions, and an exacerbation in adolescence for engagement in harmful behaviors, but there are also nuances that highlight their differences. CONCLUSION We were able to describe areas of divergence and convergence between these three concepts but not to establish a quantitative diagram of the areas of divergence and convergence. It would seem that the coexistence of sensation-seeking and impulsivity in the same individual could explain that individual's involvement in ordalique behaviors. Further studies approaching this hypothesis would seem useful in terms of preventing risk-taking behaviors such as addictive behaviors.

Abstract
Abnormal risky decision making may represent an important factor contributing to functional impairment in psychotic disorders. Previous research revealed impaired decision making under risk in patients with chronic schizophrenia. However, risky decision making is under-studied in the early course of illness. We examined risky decision making in 33 patients with early non-affective psychosis and 32 demographically matched controls, using two well-validated experimental paradigms, balloon analogue risk task (BART) and Risky-Gains task (RGT), which modeled and assessed actual risk-taking behaviors in deliberative and time-pressured decision-making situations, respectively. Our results showed that patients exhibited suboptimal decision making on the BART and were more risk averse than controls by having fewer average balloon pumps in non-burst trials, lower explosion rate and lower total points gained. On the RGT, patients also behaved more conservatively than controls, with lower overall rate in choosing the risky option. Intriguingly, patients performed comparably to controls in adjusting risk-taking pattern following punished trials, suggesting relatively preserved sensitivity to punishment in early psychosis. Risk-taking measures showed no significant correlations with any symptom dimensions, impulsivity traits, cognitive functions or antipsychotic treatment after correcting for multiple comparisons. This study is the first to investigate risk-taking propensity in early psychosis based on BART/RGT performance, and consistently indicate that patients with early psychosis displayed altered risky decision making with increased risk aversion relative to healthy participants. Further investigation is warranted to clarify the longitudinal course of aberrant risky decision making and its relationship with functional outcome in early psychosis.

Abstract
BACKGROUND Relatively little research has accrued examining risk propensity across racial and ethnic groups, especially across time and at the population level. AIMS Using a margin for error framework to conceptualize risk variation among major racial and ethnic groups, we hypothesize that African American and Hispanic adolescents will be less likely to report engaging in dangerous risk taking acts compared to White adolescents. METHODS This study examines public-use data collected on risk propensity and risky behaviors among adolescents 12-17 between 2002 and 2018 as part of the National Survey on Drug Use and Health (NSDUH). RESULTS While we observed decreased trends in risk propensity, controlling for demographic factors, we see significantly greater odds of reporting "never" engaging in risk for fun among NH Black (AOR 2.01, 95% CI 1.85-2.18) and Hispanic youth (AOR 1.47, 95% CI 1.37-1.58) as compared to NH White youth. NH Black (AOR 0.74, 95% CI 0.61-0.89) and Hispanic (AOR 0.83, 95% CI 0.71-0.98) youth are also less likely than NH White youth to report "always" taking risks for fun. Moreover, the risk propensity-risky behaviors link was weaker among African American and Hispanic adolescents. CONCLUSIONS We find compelling evidence that African American and Hispanic adolescents are less likely to endorse deriving positive reinforcement from potentially dangerous risk taking acts compared to White adolescents. These findings suggest that African American and Hispanic youth may perceive less "margin for error" when navigating their environments.

Abstract
Meta-analytic methods were used to examine ADHD-related risk-taking in children and adults, and to compare the magnitude of risk taking across behavioral, self-report, and virtual reality metrics. Potential moderators of effect size heterogeneity were also examined via a three-level multi-level approach and a hybrid meta-analytic/systematic review approach. Aggregated effect sizes obtained from 56 behavioral-task studies (82 effect sizes; ADHDN = 2577; TDN = 2606), 51 self-report studies (130 effect sizes; ADHDN = 18,641; TDN = 113,163), and 8 virtual reality studies (16 effect sizes; ADHDN = 382; TDN = 436) suggest that children and adults with ADHD exhibit moderately more risk-taking compared to children and adults without the disorder. Notably, the aggregated effect size obtained from virtual reality simulations (Hedges', g = 0.43) was 30-40% larger than effect sizes obtained from self-report and behavioral task metrics (Hedges' g = 0.31 and 0.27), respectively. Suboptimal Decision Making was the only significant moderator identified via multi-level modeling; however, comparison of subgroup effect sizes revealed potential moderating effects of ADHD presentation and trial-by-trial feedback on behavioral tasks. Collectively, findings suggest that ADHD is reliably associated with small to moderate magnitude greater risk-taking behavior and virtual reality simulations appear be the most sensitive currently available metric.

Abstract
PURPOSE Research involving adolescent risk behaviors must balance data confidentiality with participant safety when risky behaviors are revealed. This report details a safety protocol and reports the experience of two contemporaneous studies that used it with variant safety thresholds. METHODS We developed a safety protocol for research with adolescent patients and used it in two concurrent studies of adolescent patients, aged 14-18 years. Study "PC" recruited participants from a primary care adolescent medical clinic (N = 490), and Study "SP" recruited participants from subspecialty pediatric clinics (N = 434); both studies involved a similar self-administered assessment of health behaviors. The protocol sets thresholds for clinical intervention (positive safety flags) for past 3-month heavy alcohol consumption (Study PC: 10 or more drinks and Study SP: "binge-"level drinking), illicit drug use other than marijuana and alcohol in combination with a substance other than marijuana, and sets a positive screen for depression. We examined the rates of positive safety flags in both protocol settings, used significance testing to describe demographic differences between participants with and without positive flags in both studies, and described clinician experiences with protocol implementation. RESULTS In studies PC/SP, .6%/8.8% of participants were flagged for heavy alcohol consumption, respectively; .2%/0% for illicit drug use, 2.2%/.7% for combination substance use, and 14.9%/4.8% for depression. Some clinicians found managing positive flags challenging, although both studies completed recruitment on time and without serious adverse events. CONCLUSIONS The protocol was feasible in clinical settings. The findings and experiences documented in this report could be useful for future protocols.

Abstract
Previous research shows that individuals who tend to get bored frequently and intensely—the highly boredom prone—are more likely to engage in risky behaviors. However, these studies are based largely on self-reports. Here we address this gap and suggest that noisy decision-making (DM) is a potential driver for this relationship between boredom proneness and risk-taking. In Study 1, eighty-six participants completed the Balloon Analogue Risk Task (BART) while EEG was recorded. We found blunted feedback processing with higher boredom proneness, as indexed by reduced feedback-P3 amplitudes. Risk taking, as indexed by the BART, was not higher in the highly boredom prone. In Study 2a (N = 404) we directly tested the noisy DM hypothesis in an online sample using a binary choice task, and found that with higher boredom proneness, participants were more likely to alternate between choices on a trial-to-trial basis, but were not more likely to choose the risky alternative. These findings were replicated in a new sample (Study 2b), and extended to the Iowa Gambling Task (IGT; Study 3). In the IGT we found increased choice switching and reduced feedback sensitivity with higher boredom proneness. Once again, higher risk taking as indexed by the IGT was not evident in the highly boredom prone. Overall, our findings suggest that boredom proneness is associated with noisy decision-making (i.e., a tendency to alternate more between choice options regardless of risk level), and not risk-seeking per se. That is, the highly boredom prone are not necessarily attracted to risks, but rather, may be insensitive to risks due to reduced feedback sensitivity.

Abstract
Avoidant behavior is a defining feature of pediatric anxiety disorders. Although prior research has examined it from the perspective of early information processing events, there has been relatively less consideration of the processes by which anxious youth make avoidant decisions and how these choices are reinforced over time. Studies of risk taking are valuable in this regard because they consider how individuals identify the pros and cons of their choices, how they weigh potential gains and losses and estimate their respective probabilities, and how they tolerate the uncertainty intrinsic to any decision. In this review, we place risk taking within existing models of information processing in pediatric anxiety disorders and highlight the particular value of this construct for informing models of developmental psychopathology and individual differences in outcome over time. We review existing behavioral and neurobiological studies of risk taking in anxious youth and conclude by identifying directions for future research.

Abstract
In the present era, women are recognized as successful entrepreneurs through their strong desire, qualities, and capabilities for robust economic development. Due to such an important contribution of women in economic development, we propose to investigate the factors which affect women entrepreneur's success in Pakistan. Data were collected through structured questionnaires from 181 registered SMEs operating in Pakistan. A conceptual model is developed, while SPSS and AMOS software's are used for analysis. The results indicate that the internal factors including the need for achievements, risk-taking, and self-confidence and external factors including economic factors and socio-cultural factors have a positive and significant influence on the success of women-owned enterprises. This research recommends Small and Medium Enterprises Development Authority (SMEDA), policymakers, and practitioners to encourage women entrepreneurs to run their businesses for the long term by providing a variety of incentives and supports related to those internal and external factors. Numerous studies have been conducted to test the different factors' effects on women's entrepreneurial success, but our study investigated some psychological, cultural, and religious factors that are still almost untouched especially in Pakistan. The current study also contributes to the existing literature through empirical shreds of evidence.

Abstract
Older age has often, but not always, been associated with less risk taking. Inconsistencies may be due to diversity in the risk-taking measures used and/or individual differences in cognitive abilities. We investigated the robustness of age differences in risk taking across three measures, and tested whether age differences in risk taking remained after accounting for cognitive abilities. Younger (aged 25-36) and older (aged 60+) adults completed behavioral (i.e., Balloon Analogue Risk Task, BART) and self-report (i.e., framing tasks and Choice Dilemmas Questionnaire) measures of risk, as well as several measures of cognitive ability (i.e., analytic thinking, numeracy, processing speed, memory, and attention). Older adults showed significantly less risk taking than younger adults on the behavioral measure of risk, but not on the two self-report measures. Older adults also had significantly lower analytic thinking, slower processing speed, and worse executive control compared to younger adults. Less risk taking on the BART was associated with lower analytic thinking and numeracy, slower processing speed, and worse shifting of attention. Age differences in risk taking on the BART remained after accounting for older adults' lower scores on tests of cognitive abilities. Implications for measuring age differences in risk taking are discussed.

Abstract
This study aimed to systematically appraise cross-sectional research that compared the cognitive performance of individuals in the acute phase of BN and/or AN to HCs on measures of impulsivity and compulsivity. The results of the systematic review showed support for the trans-diagnostic approach to eating disorders. There was no strong evidence to support the characterisation of AN as high in compulsivity (and low in impulsivity), nor to support the characterisation of BN as high in impulsivity (and low in compulsivity). There appeared to be mixed findings for both impulsivity and compulsivity across AN and BN. Results were highly variable due to the heterogeneous tasks used, and lack of replication across studies. There was no consensus amongst the included studies on the most appropriate task and/or outcome measures that should be used to study the constructs of impulsivity and compulsivity.

Abstract
Many biological studies require the capture of individuals for sampling, for example for measurement of morphological or physiological traits, or for marking individuals for later observations. Capture methods employed often vary both within and between studies, and these differing methods could be more or less effective in capture of different individuals based on their morphology or behavior. If individuals that are prone to capture by the selected method differ with respect to traits of interest, such sampling bias could generate misleading or simply inaccurate results. The selection of capture methods could introduce two different forms of sampling bias, with the individuals that are sampled differing from the population at large or with individuals sampled via one method differing from individuals that could be sampled using a different method. We investigated this latter form of sampling bias by comparing individual birds sampled using two common capture techniques. We caught free-ranging black-capped chickadees (Poecile atricapillus) using walk-in traps baited with seed and mist nets paired with playback of an audio stimulus (conspecific mobbing calls). We measured 18 traits that we expect might vary among birds that are trappable by these differing methods—one that targets birds that are food motivated and potentially less neophobic and another that targets birds that respond readily to a perceived predation risk. We found no differences in the sex, morphology, initial and stress-induced corticosterone concentrations, behavioral response to a novel object, or behavioral response to a predator between individuals captured by these two methods. Individual variation in the behavioral response to a novel object was greater among birds caught by mist nets, suggesting this method might provide a sample that better reflects population-level individual variation. We do not know if the birds caught by these two methods provide a representative sample of the population at large, but can conclude that selection of either of these two common capture methods can similarly sample mean trait values of a population of interest. To accurately assess individual variation, particularly in behavior, mist nets might be preferable.

Abstract
Anxiety is common in adolescence and has been linked to a plethora of negative outcomes across development. While previous studies of anxiety have focused on threat sensitivity, less work has considered the concurrent development of threat- and reward-related neural circuitry and how these circuits interact and compete during puberty to influence typical adolescent behaviors such as increased risk taking and exploration. The current review integrates relevant findings from clinical and developmental neuroimaging studies to paint a multidimensional picture of adolescent-onset anxiety against the backdrop of typical adolescent development. Ultimately, this paper argues that longitudinal neuroimaging studies tracking approach and avoidance motivations across development are needed to fully understand the mechanisms underlying the development of anxiety in adolescence and to identify and provide effective interventions for at-risk youth.

Abstract
Background The pandemic associated with the new SARS-CoV-2 coronavirus continues to spread worldwide. The most favorable epidemic control scenario, which provides long-term protection against COVID-19 outbreak, is the development and distribution of an effective and safe vaccine. The need to develop a new COVID-19 vaccine is pressing; however, it is likely to take a long time, possibly several years. This is due to the time required to demonstrate the safety and efficacy of the proposed vaccine. and the time required to manufacture and distribute millions of doses. Objectives To accelerate this development and associated safety testing, the deliberate infection of healthy volunteers has been suggested. The purpose of this short communication is to describe the ethical aspects of this type of testing, Results Deliberate infection of volunteers with a dangerous virus such as SARS-CoV-2 was initially considered unethical by researchers; but the current pandemic is so different from previous ones that these studies are considered ethical if certain criteria are met. Participants in human challenge studies must be relatively young, in good health and must receive the highest quality medical care, with frequent monitoring. Tests should also be performed with great caution and specialized medical supervision. Besides, the fact that obtaining vaccines faster through deliberate infection studies of healthy people has greater benefits than risks, has been demonstrated by obtaining other vaccines in other historical pandemics such as: smallpox, influenza, malaria, typhoid fever, Dengue fever and Zika. Conclusions One possibility to shorten the time required for the development of COVID-19 vaccines is to reduce clinical phases II and III by using human challenge studies through eliberate infection of healthy volunteers with SARS-CoV-2 after administration of the candidate vaccine. Accelerating the development of a COVID-19 vaccine even for a few weeks or months would have a great beneficial impact on public health by saving many lives. Graphical abstract ![]()

Abstract
Success at an Olympic level can come down to the smallest of margins. However little research has been conducted into how the menstrual cycle affects elite athletes' performance and decision making. This study uses a combination of quantitative and qualitative research methods to explore this question. Physiological performance data was collected from eight elite athletes for 7 months and analyzed as a function of menstrual phase. The Cambridge Gambling Task (CGT) was used to test decision making and testing occurred twice in one cycle, during the early follicular phase and during the mid-luteal phase. Menstrual cycle phase was determined using menstrual cycle mapping and urine ovulation tests. In the qualitative part of this project, two elite athletes, two Olympic level athletes, and two coaches participated in semi-structured interviews. The study found that physiological performance was significantly better during the menses phase (MP) compared to the proliferative and secretory phases (PSP). There was variation in how elite athletes were individually affected however. Oral contraceptive users showed a greater performance change from MP to PSP suggesting that oral contraceptives may be detrimental to performance in some athletes. The results of the CGT showed that impulsivity is significantly affected by menstrual cycle phase. Risk taking, error rates and response times were not affected. The qualitative interviews revealed that elite athletes and their coaches understand little of the menstrual cycle. Despite this, there are preconceptions that it negatively effects performance during the menses phase. The findings suggest that the menstrual cycle can have a significant effect on an elite athlete's performance and this paper discusses how individuals can possibly improve aspects of physiological and psychological performance by understanding and monitoring their menstrual patterns.

Abstract
Heightened risk-taking tendencies during adolescence have been hypothesized to be attributable to physiological differences of maturation in key brain regions. The socioemotional system (e.g., nucleus accumbens), which is instrumental in reward response, shows a relatively earlier development trajectory than the cognitive control system (e.g., medial prefrontal cortex), which regulates impulse response. This developmental imbalance between heightened reward seeking and immature cognitive control potentially makes adolescents more susceptible to engaging in risky activities. Here, we assess brain structure in the socioemotional and cognitive control systems through viscoelastic stiffness measured with magnetic resonance elastography (MRE) and volumetry, as well as risk-taking tendencies measured using two experimental tasks in 40 adolescents (mean age = 13.4 years old). MRE measures of regional brain stiffness reflect brain health and development via myelin content and glial matrix makeup, and have been shown to be highly sensitive to cognitive processes as compared to measures of regional brain volume and diffusion weighted imaging metrics. We find here that the viscoelastic and volumetric differences between the nucleus accumbens and the prefrontal cortex are correlated with increased risk-taking behavior in adolescents. These differences in development between the two brain systems can be used as an indicator of those adolescents who are more prone to real world risky activities and a useful measure for characterizing response to intervention.

Abstract
Adolescents with ADHD demonstrate increased risk-taking behavior (RTB) like substance abuse and dangerous traffic conduct. RTB in adolescence is more likely under peer influence. The current investigation (1) tests the hypothesis that adolescents with ADHD are particularly susceptible to such influence and (2) tests whether groups differed in autonomic reactivity to peer influence. Adolescent boys between 12 and 19 years with (n = 81) and without (n = 99) ADHD performed the Balloon Analogue Risk Task twice. In the peer condition, a highly credible virtual peer manipulation that encouraged risk taking was added, in the solo condition this was absent. Autonomic reactivity was indexed by heart rate (HR), pre-ejection period (PEP) and respiratory sinus arrhythmia (RSA). All adolescents engaged in more risk taking in the peer condition relative to solo condition. Autonomic differences between groups were only found on PEP: a stronger sympathetic response to peer influence was observed in typically developing adolescents relative to adolescents with ADHD. Increased physiological stress (as indexed by PEP) in the peer relative to the solo condition predicted peer-induced risk taking in all adolescents. We conclude that susceptibility to peer influence is not exaggerated in ADHD but rather reflects a general tendency of adolescents. As adolescents experiencing peer influence as stressful are most susceptible to peer influence, we suggest that increasing resistance to peer influence may be an important treatment aim for these adolescents specifically.

Abstract
INTRODUCTION This study examined changes in substance use from adolescence to young adulthood as related to adolescents' risk taking, sensation seeking, antisocial activities, and personality traits. METHODS Chilean youth (N = 890, 52% female) were studied in adolescence (14.5 and 16.2 years) and young adulthood (M age 21.3 years). Risk taking was assessed via a laboratory-based performance task (Balloon Analogue Risk Task), and self-administered questionnaires assessed sensation seeking, antisocial behaviors, personality and substance use. RESULTS Frequent involvement in sensation seeking and antisocial activities were associated with increased odds of continued marijuana use from adolescence to young adulthood and of illicit substance use at young adulthood. High risk taking was associated with a reduced likelihood of discontinuing marijuana use at young adulthood, and high agreeableness and conscientiousness were associated with reduced likelihood of new onset marijuana use and illicit substance use at young adulthood. CONCLUSIONS Results highlight specific risk-taking tendencies and personality characteristics that relate to initiating, continuing, or discontinuing substance use at entry into adulthood. Sensation seeking and involvement in antisocial activities were the two foremost risk factors for continued use, which is a forecaster of drug dependence. Findings suggest potential prevention and intervention targets for abstaining from or discontinuing substance use as youth transition to adulthood.

Abstract
The biological, environmental, and psychosocial changes that occur in adolescence engender an increase in risk taking often linked to the high rates of motor vehicle crashes amongst young drivers. Most U.S. adolescents suffer from poor sleep, which is known to exacerbate the risk of driving crashes; however, research has yet to uncover a neurobiological link between sleep and risky driving in adolescence. Here, we examined potential moderators of the sleep-risk relation in fifty-six adolescents (14-18y/o) as they completed a driving task during fMRI. While poor sleep was associated with increased risky driving (i.e., running more yellow lights), good sleep emerged as a novel buffer against risky driving in lower sensation-seeking adolescents. Neural activity in the ventral striatum (VS), a key node of the risk-taking circuit, also moderated the sleep-risk association: sleep was related to risk-taking in individuals demonstrating high, but not low, VS response during risky decision-making, suggesting that reward-related neural response may underly the connection between sleep and risk-taking in adolescence. This study sheds light on the risk of driving crashes in youth by highlighting sleep as both an exacerbator and a buffer of risky driving in adolescence. Taken together, these results underscore the importance of improving adolescent sleep.

Abstract
Positive risks benefit adolescent development without posing the same public safety concerns as negative risks, but little is understood about the psychological characteristics of positive risk taking. This study explored the shared and unique correlates of positive and negative risk taking in 223 adolescents (48% female) ages 16-20 years (M = 18.1; SD = 0.81). Positive and negative risk taking were both associated with higher sensation seeking. Unlike negative risk taking, positive risk taking was not associated with impulsivity or risk taking on experimental tasks. Further, positive risk taking was associated with lower reward sensitivity, higher punishment sensitivity, and greater school engagement than negative risk taking. The findings offer new insights for prevailing models of adolescent risk behavior and suggest positive risk taking may be particularly beneficial in the school context.

Abstract
Adolescents with mild to borderline intellectual disability (MBID) show more daily life risk taking than typically developing adolescents. To obtain insight in when these "risk-taking adolescents" especially take risks, we investigated main and interaction effects of (a) MBID, (b) sex, and (c) type of peer influence on risk taking. The Balloon Analogue Risk Task (BART) was used as a proxy of real-life risk taking. 356 adolescents (12-19 years, 51.7% MBID, 63.4% boys) were randomly assigned to one of three BART peer-influence conditions: solo (no peers), positive risk encouragement (e.g., 'You are cool if you continue') or negative risk encouragement (e.g., 'You are a softy if you do not continue'). The main finding was that boys with MBID took more risks than typically developing boys in the negative risk encouragement condition. Boys with MBID also took more risks in the negative risk encouragement condition compared to the solo condition, whereas typically developing boys did not. There were no such effects for girls. Surprisingly, boys with MBID took less risks in the solo condition than typically developing boys. We conclude that boys with MBID especially show high risk taking when peers belittle or threat with exclusion from the peer group. Prevention and intervention programs should specifically target boys with MBID to teach them to resist negative risk encouragement by peers.

Abstract
INTRODUCTION Many studies have investigated the influence of stress on decision-making. However, results are equivocal and the exact role of increased noradrenaline and cortisol after stress remains unclear. Using pharmacological manipulation, we investigated the influence of noradrenergic and glucocorticoid activity on risky decision-making in a gambling task that included mixed-gamble trials (gains and losses are possible) and gain-only trials. METHODS AND MATERIALS One hundred-and-four healthy young men participated in our randomized, double-blind, placebo-controlled, between-group study. Participants were randomly assigned to one of four groups: (A) yohimbine, (B) hydrocortisone, (C) yohimbine and hydrocortisone, or (D) placebo. Frequency of risky choices, i.e., monetary risk taking, was the dependent variable. We also investigated the influence of hydrocortisone and yohimbine on loss aversion, which is the tendency to overweigh losses compared with gains. RESULTS Participants chose the risky option less often after receiving hydrocortisone compared with no hydrocortisone. This effect was strongest in the gain-only trials. Yohimbine had no effect. Loss aversion was not affected by hydrocortisone or yohimbine. DISCUSSION Decreased reward processing may explain the reduction of risk taking by hydrocortisone in gain-only trials. The effects of stress hormones on different decision-related constructs and processes hence require further investigation.

Abstract
Substance use is strongly associated with impaired decision making, with cocaine use particularly linked to elevated risky and impulsive choice. It is not clear, however, whether such maladaptive decision making is a consequence of cocaine use or instead precedes and predisposes individuals to cocaine use. The current study was designed to specifically address the latter possibility with respect to risky choice in both male and female rats. Rats were first trained in a "Risky Decision-making Task" (RDT), in which they made discrete choices between a small, "safe" food reward and a large, "risky" food reward accompanied by increasing probabilities of mild footshock punishment. After reaching stable performance, rats underwent jugular catheter surgery followed by either short-access cocaine self-administration sessions (2 h, 0.5 mg/kg/infusion) for 5 days or long-access cocaine self-administration sessions (6 h, 0.5 mg/kg/infusion) for 14 days. Under short-access conditions, there was no relationship between risk preference and changes in cocaine intake over time, but greater risk aversion in females predicted greater overall cocaine intake. Under long-access conditions, heightened risk taking predicted greater escalation of cocaine intake over the course of self-administration, supporting the notion that pre-existing risk-taking behavior predicts cocaine intake. Collectively, results from these experiments have implications for understanding and identifying pre-existing vulnerabilities to substance use, which may lead to strategies to prevent development of substance use disorders.
