Individual differences and risk taking in rock climbing

ObjectivesThe primary objective of the study was to challenge the notion that risk taking populations are homogenous, and that risk taking in sport necessarily reflects the expression of trait sensation seeking. A secondary objective was to examine the potential role of additional individual differences, such as self-efficacy and impulsivity, which have traditionally received limited attention.DesignQuantitative cross-sectional study.MethodsOne hundred and sixteen active rock climbers completed the Impulsive-Sensation Seeking Scale, a domain-specific self-efficacy scale, and behavioral measures of ability, experience and risk taking in rock climbing.ResultsThose high in self-efficacy and male climbers were likely to take greater risks; small associations with age, sensation seeking and impulsivity were also observed, though these were not in the hypothesized direction and failed to predict unique variance in regression analyses.ConclusionsTo challenge themselves, rock climbers may take calculated additional risks when they feel confident in their ability to manage those risks. Researchers should not assume homogeneity within risk taking populations, or that people take risks in all domains due to elevated sensation seeking needs.     

Substance Abuse Counselors and Moral Reasoning: Hypothetical and Authentic Dilemmas

This exploratory study examined the assumption that the level of moral reasoning (Defining Issues Test; J. R. Rest, 1986) used in solving hypothetical and authentic dilemmas is similar for substance abuse counselors (N = 188). The statistical analyses used were paired‐sample t tests, Pearson product‐moment correlation, and simultaneous multiple regression. This study found that when solving dilemmas of a personal nature (authentic dilemmas), substance abuse counselors' level of moral reasoning was lower. Implications for counselor education are presented.     

Psychological profiles and emotional regulation characteristics of women engaged in risk-taking sports

We investigated the psychological profiles and emotional regulation characteristics of women involved in risk-taking sports. The research sample (N=180) consisted of three groups of women engaged in: (1) non-risk sports (N=90); (2) risk-taking sports for leisure purposes (N=53); or (3) risk-taking sports as professionals (N=37). Each participant completed five questionnaires, the Sensation Seeking Scale, the Bem Sex Role Inventory, the Barratt Impulsiveness Scale, Risk & Excitement Inventory, and the Toronto Alexithymia Scale. The results revealed significant differences between the groups' profiles. Of particular interest are the differences that exist between the profiles of Group 2 (escape profile, masculine gender identity, and high scores on sensation seeking, impulsivity, alexithymia) and Group 3 (compensation profile, androgynous gender identity, average score on sensation seeking, and low scores on impulsivity, alexithymia). We propose that the professional woman might be considered a model for preventing destructive risk-taking behaviors.     

An Assessment of the Psychometric Properties of the Brief Sensation Seeking Scale for Children

Sensation seeking is a trait that predicts a wide range of real-life risk behavior, such as substance abuse and gambling problems. Sensation seeking is often assessed with the Sensation Seeking Scale. Several adaptations of this questionnaire have been made, for example, to abbreviate it and to make it suitable for children. However, studies on sensation seeking in children are scarce. The aim of this study was to investigate sensation seeking in children (N = 158, M age = 11.4 years). The Brief Sensation Seeking Scale for Children (BSSS–C) was translated into Dutch and psychometric properties were examined. Internal consistency was high, and the factor structure showed close resemblance with previous research. Test–retest and split-half reliabilities were acceptable, as was convergent validity with self-reported symptoms of psychopathology (attention problems and aggressive behavior). Construct validity was adequate, with more sensation seeking in boys than in girls. No effects of age were found. To sum up, sensation seeking can be measured in children in a valid and reliable way. The correlation of sensation seeking with high-risk behaviors emphasizes the importance of assessment early in development.     

Psychopathy and aggressive behaviour among Nigerian male prison inmates: The moderating role of substance abuse

This study investigated the moderating role of substance abuse in the relationship between psychopathy and aggression among male prison inmates. Two hundred and sixty-seven male prison inmates from the Nigerian Prison Services were participants. The inmates were incarcerated for armed robbery (27.3%), theft (31.1%), murder (12.8%), rape/assault/child abuse (19.1%), burglary/arson (5.6%) and kidnapping (1.5%) in Enugu prisons, Nigeria. Their mean age was 28.32; SD = 5.53. Their length of time in prison ranges from 1 to 12 years, with a mean of 3.38 years. Participants responded to self-reported measures of aggression, psychopathy, and drug abuse. The result of the moderated regression analysis indicated substance abuse to moderate the relationship between primary psychopathy and verbal aggression, and between secondary psychopathy and hostility. The study findings underscore the importance of psychological intervention aimed at addressing aggression among prison inmates with histories of substance abuse and psychopathy.     

When cooler heads prevail: peacemakers in a sports riot.

Male sports fans (N = 74) were asked to estimate the likelihood that they would intervene in a crowd disturbance in an attempt to stop the fighting. They also completed a battery of measures that included their attitude toward law and order, fight history, the false consensus effect, impulsivity, psychopathy, sensation seeking, anger, physical aggression and identification with their favorite team. Law and order, body mass, anger and the false consensus effect were positively related to peacemaking whereas sensation seeking was negatively related. A multiple regression analysis yielded a solution that accounted for 32.3% of the variance with anger and attitude toward law and order emerging as the best predictors.     

Sexual Sensation Seeking and Sexual Compulsivity Scales: Validity,and Predicting HIV Risk Behavior

Two studies are presented that evaluate newly developed scales of sensation seeking and sexual compulsivity. Results showed that the scales were reliable and correlated with convergent and divergent measures in expected directions in samples of both gay men (N = 296) and inner city low-income men and women (N = 158). Consistent with theories of sensation seeking, the scales corresponded to an attraction toward a range of sexual practices, including increased frequencies of unprotected intercourse and a greater number of sexual partners. As expected, sexual compulsivity was not related to variety and novelty in sexual practices, but was associated with lower levels of self-esteem and resistance to adopting sexual risk-reducing strategies. However, important differences were observed between the gay men and heterosexual samples; scales correlated with substance use only among gay men, and sexual compulsivity was related to a range of sexual practices only among heterosexuals. The sensation seeking and Sexual Compulsivity Scales were therefore reliable, appeared valid, and useful in predicting sexual risk behaviors.     

小鼠新颖寻求特质对酒精的运动激活效应的影响

新颖寻求(或感觉寻求)特质与许多成瘾药物的易感性密切相关。例如, 高、低新颖寻求动物对可卡因、苯丙胺和吗啡等成瘾药物的奖赏、运动激活、强化效应的反应存在差异。长期饮用酒精也容易成瘾, 但尚未发现关于新颖寻求特质影响酒精成瘾的报道。本实验采用药物成瘾研究中常用的自发活动模型, 考察了高、低新颖寻求动物在酒精急性处理、慢性处理和激发过程中的行为表现。实验过程中首先采用两种新颖寻求模型, 即新颖环境中自发活动模型和新颖客体偏爱模型, 将昆明小鼠分别区分为高、低自发活动组和高、低新颖客体偏爱组, 连续10天给予酒精(2g/kg/d, i.p.)或等量盐水处理, 戒断2天后所有小鼠接受酒精(2g/kg)激发。实验结果表明, 新颖环境低自发活动小鼠比新颖环境高自发活动小鼠对酒精急性、慢性处理导致的运动激活效应更敏感; 在酒精激发期前者的自发活动水平也高于后者。本实验结果说明新颖环境中自发活动特质影响动物对酒精导致的运动激活效应的反应。     

精神病态的家庭风险因素

精神病态(psychopathy)是一种个体表现在人际关系、情感、生活方式和反社会特征等方面的人格障碍, 其特征为自我中心、欺骗、冲动、缺乏共情、缺乏罪恶感等。以往研究偏向于精神病态的生理机制, 认为精神病态具有高度的遗传性, 近期越来越多的研究发现家庭因素对精神病态的重要影响。这些因素包括：产前风险因素、破碎家庭、不良的教养方式、不安全的亲子依恋关系和童年期虐待等。未来的研究应探讨家庭因素对各个精神病态亚型的作用机制, 探索抑制精神病态表达的保护性环境因子, 并构建精神病态的生物心理社会模型等。     

Moral/conventional transgression distinction and psychopathy in conduct disordered adolescent offenders

To date there are no studies examining the ability to make a moral/conventional transgression distinction in adolescent offenders with psychopathic traits. Based on the Psychopathy Checklist: Youth Version, we compared males with high (HP, n = 45), medium (MP, n = 31) and low psychopathy scores (LP, n = 39) on the moral convention distinction task. Under normal rule conditions the psychopathy groups did not differ in their ability to make a moral/conventional distinction. The HP group tended to view both transgression types as more permissible and conventional transgressions as less serious, than the LP group. Under modified rule conditions, the HP group exhibited reduced moral/conventional distinction scores compared to the MP group. The findings only partially replicate findings from previous M/C studies in children and adults with psychopathic traits. The work fits with more recent reports suggesting that psychopathy is not strongly associated with marked difficulties in cognitive theory of mind, perspective taking and moral judgements. Future studies should focus on the affective aspects of moral reasoning in offender samples.     

Conceptual and Moral Development of Substance Abuse Counselors: Implications for Training

The relationship among substance abuse counselors' education, experience, recovery status, and cognitive development (conceptual complexity and moral reasoning levels) was examined in a simultaneous multiple regression. Significant relationships were found between counselors' level of conceptual complexity and moral reasoning and their education. Implications for counselor training are presented.     

The amygdala and ventromedial prefrontal cortex in morality and psychopathy

Recent work has implicated the amygdala and ventromedial prefrontal cortex in morality and, when dysfunctional, psychopathy. This model proposes that the amygdala, through stimulus-reinforcement learning, enables the association of actions that harm others with the aversive reinforcement of the victims' distress. Consequent information on reinforcement expectancy, fed forward to the ventromedial prefrontal cortex, can guide the healthy individual away from moral transgressions. In psychopathy, dysfunction in these structures means that care-based moral reasoning is compromised and the risk that antisocial behavior is used instrumentally to achieve goals is increased.     

Does adolescent risk taking imply weak executive function? A prospective study of relations between working memory performance,impulsivity, and risk taking in early adolescence

Studies of brain development suggest that the increase in risk taking observed during adolescence may be due to insufficient prefrontal executive function compared to a more rapidly developing subcortical motivation system. We examined executive function as assessed by working memory ability in a community sample of youth (n = 387, ages 10 to 12 at baseline) in three annual assessments to determine its relation to two forms of impulsivity (sensation seeking and acting without thinking) and a wide range of risk and externalizing behavior. Using structural equation modeling, we tested a model in which differential activation of the dorsal and ventral striatum produces imbalance in the function of these brain regions. For youth high in sensation seeking, both regions were predicted to develop with age. However, for youth high in the tendency to act without thinking, the ventral striatum was expected to dominate. The model predicted that working memory ability would exhibit (1) early weakness in youth high in acting without thinking but (2) growing strength in those high in sensation seeking. In addition, it predicted that (3) acting without thinking would be more strongly related to risk and externalizing behavior than sensation seeking. Finally, it predicted that (4) controlling for acting without thinking, sensation seeking would predict later increases in risky and externalizing behavior. All four of these predictions were confirmed. The results indicate that the rise in sensation seeking that occurs during adolescence is not accompanied by a deficit in executive function and therefore requires different intervention strategies from those for youth whose impulsivity is characterized by early signs of acting without thinking.     

Predicting high risk sexual behaviour in heterosexual and homosexual men: the roles of impulsivity and sensation seeking

Impulsivity and sexual sensation seeking were examined as personality correlates of high risk sexual behaviour — unprotected sex with multiple partners — in samples of heterosexual (n=112) and homosexual (n=104) men. Among heterosexuals, both personality variables were associated with frequency of unprotected sex but only sexual sensation seeking was associated with number of sex partners. Sexual sensation seeking also mediated the association between use of drugs other than alcohol and number of sex partners. Among homosexuals, no personality or substance use variables predicted high risk sexual behaviour. Implications of the findings for the study of determinants of sexual risk-taking are discussed.     

Moral judgment and self-reported moral events in adulthood

As part of a 13-year study of the development of reasoning about the Good Life and moral judgment, 29 middle-class, well-educated adults, ranging in age from 18 to 80 years, were interviewed twice, 4 years apart on Standard Form Moral Judgment interviews and were asked to describe their own moral events that occurred recently. Both times, the average moral judgment score on the hypothetical dilemmas was about stage 4. The reasoning in the spontaneously reported moral events was significantly lower, although the two scores were highly correlated. Difference scores between the two were not related to scores on the hypothetical dilemmas. While there were no significant gender differences in scores on the hypothetical dilemmas, there were in scores on spontaneously reported events favoring males. The philosophic quality of the reported events could be easily categorized by traditional moral-philosophic categories; about half of the events contained traditional deontic moral content (moral right); the other half contained material defined as the moral good. The context of most events was interpersonal as opposed to societal. The most frequent issue discussed concerned honesty about financial issues, particularly income tax evasion. Ways to expand the research on adult moral experience are discussed.     

网络成瘾者的行为冲动性——来自爱荷华赌博任务的证据

以84名大学生为被试(网络成瘾和对照组被试各42名),采用感觉寻求量表和爱荷华赌博任务(Iowa Gambling Task)范式比较两组被试在感觉寻求水平和决策行为反应模式方面的差异.结果发现,与对照组被试相比,网络成瘾者的感觉寻求总分和去抑制、厌恶单调及寻求激动和惊险三个分量表得分显著增加,在IGT任务中优先选择收益和惩罚频率高的不利扑克牌,其冒险的决策策略并没有随着决策次数的增加而改变.这表明网络成瘾者的决策功能受损并表现出“即时收益优先”的决策模式和对强化物潜在风险的高耐受性.     

Substance-related disorders among juvenile offenders: what role do psychopathic traits play?

Substance use disorders are associated with psychopathy, a personality disorder that is heterogeneous in both adults and youth; secondary variants of psychopathy with comorbid psychopathology and primary variants without comorbidity show distinct correlates and outcomes. In adult criminal populations, secondary variants report greater substance abuse compared with primary variants. The primary aim of this study is to replicate and extend these findings to a juvenile offender population. Compared with primary variants of juvenile psychopathy, secondary variants (a) reported significantly more frequent substance use--particularly alcohol--within the 6 months prior to incarceration (d = .43), (b) were almost twice as likely to abuse substances while incarcerated, and (c) were more likely to be diagnosed with a current Diagnostic and Statistical Manual of Mental Disorders (4th ed., text rev.; DSM-IV; American Psychiatric Association, 2000) substance use disorder. Practical implications for working with justice-involved youth are discussed.     

Internet Safety and the Silver Surfer: The Relationship Between Gist Reasoning and Adults' Risky Online Behavior

Currently, fewer older adults are online compared with younger generations. However, with many new initiatives aiming to significantly increase the number of older internet users, they will increasingly be exposed to potential victimisation from internet fraud, a fundamental issue affecting all adult internet users. Despite this, little research has examined online risk‐taking across the adult lifespan or adults' reasoning about risky online behaviors. Using fuzzy trace theory, we investigated adults' online risk‐taking behavior and intentions, and whether these behaviors were related to different ways of reasoning about risk, namely, gist reasoning (using qualitative, intuitive knowledge) and verbatim reasoning (using quantitative, specific knowledge). Participants (326 adults, 18–79 years old, M_age = 49.54 years) reported their past risk‐taking behavior, future online risk intentions, gist and verbatim reasoning about online risk, sensation seeking, and time spent online. Age was negatively correlated with past risk‐taking, time online, future risk intentions, and sensation seeking. However, time spent online was positively related to future risk intentions, suggesting that spending more time using the internet could lead individuals to take more risks. Increased verbatim reasoning predicted increased intentions to take online risks, while gist reasoning predicted reduced intentions to take risks online. Our findings extend online risk research applying fuzzy trace theory to adolescents and young adults and suggest that online safety training incorporating gist‐based reasoning strategies could benefit all adults and, in particular, older generations.

Risk Factors of Sexual Aggression and Victimization Among Homosexual Men1

This study examined risk factors of sexual aggression and victimization among homosexual men (N= 310). They completed the Homosexual Experiences Survey to record sexual aggression and victimization and provided information about 2 groups of potential risk factors: childhood abuse and sexual lifestyle (number of partners, age at first intercourse, age at coming out, accepting or paying of money for sex, and rape proclivity). One in 4 respondents reported severe forms of sexual victimization; 17% reported moderate victimization. Prevalence of perpetration of sexual aggression was almost 20% for severe aggression and 9% for moderate aggression. The risk of victimization increased as a function of childhood abuse as well as high number of partners and acceptance of money for sex. The risk of committing sexual aggression was positively related to childhood abuse, acceptance and payment of money for sex, high number of sexual partners, and rape proclivity. The findings are discussed in relation to evidence on heterosexual aggression.     

Alcohol and drug abuse-dependence disorders in psychopathic and nonpsychopathic criminal offenders

Co-occurrence of psychopathy (assessed with the Psychopathy Checklist) and lifetime Diagnostic and Statistical Manual of Mental Disorders (3rd ed.) alcohol and drug disorders (assessed with the National Institute of Mental Health Diagnostic Interview Schedule) was examined in a sample of 360 male inmates. Consistent with previous research that used diagnoses of antisocial personality disorder, psychopaths were more likely than nonpsychopaths to have lifetime diagnoses of alcoholism, any drug disorder, and multiple drug disorders. We also examined the relation between substance abuse and the 2 factors of the Psychopathy Checklist. Substance abuse was significantly related to general social deviance (Factor 2) but was unrelated to core personality features of psychopathy (Factor 1). We present two possible models of psychopathy (unitary syndrome vs. dual-diathesis model) that may account for the association between psychopathy and substance abuse.
