Selective review,optimism and HIV risk perception

Abstract

Research suggests that review of risk factors increases optimism about health. The present experimental study explored the effects of reviewing risk increasing and risk decreasing factors on HIV risk perception (own risk, others' risk, optimism), self efficacy and behavioural intentions. 164 heterosexual subjects completed a questionnaire concerning their beliefs about HTV and their sexual behaviour. Subjects were allocated to either the risk increasing condition (eg. since being sexually active how often have you asked your partners HIV status?), the risk decreasing condition (eg. since being sexually active how often have you tried to select your sexual partners carefully?), or a control group. The results suggest that review of risk decreasing factors increased optimism and that this change in optimism was related to an increase in perceived others' risk. The results are discussed in terms of theories of selective focus and egocentricism in risk perception and the implications for health promotion.     

气质性乐观的正性偏向及其神经生理研究证据

气质性乐观是对未来的总体的积极期待。乐观能够带给个体诸多好处, 如有利于提高身体健康, 提高幸福感, 促进成功等等, 究其原因可能是乐观者存在正性偏向。这一偏向主要体现在注意、知觉、记忆、解释风格、应对策略的选择、情绪、期待及动机方面。而乐观者正性偏向产生的神经生理机制可能与前扣带回喙部、前额叶皮质的激活水平变化有关。未来研究可将乐观的核心--期待--作为重点, 整合期待−价值理论、人格理论与神经基础来进一步探讨乐观的心理机制。     

影响直升机飞行员飞入IMC的心理因素——一项基于三十年间NTSB事故报告的研究

气象因素对通航运行安全有重要影响,以此可以明确“直升机飞行员飞入仪表气象条件将会威胁飞行安全”这一基本事实。然而从近30年来美国国家运输安全委员会所记录的200起在仪表气象条件下的直升机事故来看,有近一半的飞行员有意地飞入仪表气象条件。这驱使研究者探究这一行为背后的心理因素。基于大量的文献,总结出飞行员的知识/经验、决策动机、情景评估、风险管理、认知偏差和社会压力能够合理地解释这一行为。     

自恋与行为抑制/激活系统的关系：元分析

运用元分析方法探讨自恋与行为抑制/激活系统的关系。经过文献检索和筛选, 纳入原始文献19篇, 包含25个独立样本, 共7702名被试。根据同质性检验结果, 选用随机效应模型。结果发现, 自恋与行为抑制系统存在中度负相关(r = -0.27, 95% CI为[-0.34, -0.21]), 自恋测量工具在两者间起显著的调节作用; 自恋与行为激活系统存在高度正相关(r = 0.46, 95% CI为[0.40, 0.52]), 被试类型在两者间起显著的调节作用。自恋与行为抑制/激活系统的密切关系支持了自恋的主体性理论和人格强化敏感性理论。     

飞行员风险知觉：概念、测量及研究理论取向

Self‐presentation style in job interviews: the role of personality and culture

Chronic self‐promoters may thrive in job interviews where such behavior is encouraged. In Study 1, 72 participants were videotaped as they simulated the job applicant role. Accountability was manipulated by the expectation of expert versus nonexpert interviewers. As accountability increased, self‐promotion tended to decrease among non‐narcissists but increase among narcissists. Ingratiation showed no interaction or main effects. In Study 2, 222 raters evaluated applicant videos varying in narcissism (high vs. low) and ethnicity (European heritage vs. East Asian heritage). Chronic self‐promoters (i.e., European‐heritage narcissists) were given the most positive evaluations. Detailed behavior analyses indicated that the narcissism advantage was derived primarily from frequent self‐praise and the European‐heritage advantage from use of active ingratiation tactics. In sum, self‐presentation styles that pay off in the (Western) interview context are highly selective.     

Effects of fear on risk and control judgements and memory: Implications for health promotion messages

Health promotion messages that evoke fear are often used to decrease unrealistic optimism regarding risks, convince people to control their behaviour, and make risks memorable. The relations among emotions, risk and control judgements, and memory are not well understood, however. In the current study, participants (N = 94) were assigned to fearful, angry, happy, or neutral emotion-elicitation conditions. They then rated the likelihood of experiencing 15 negative and 15 positive matched outcomes and rated their degree of control over each outcome. A surprise memory test followed. Fear decreased unrealistic optimism, but the greater the intensity of fear reported the less control participants believed they had over outcomes. Fear also led to poorer memory for outcomes. Across all participants, the lower their ratings of optimism and control concerning outcomes, the less likely they were to recall them. Implications for the use of emotionally evocative material in health promotion messages are discussed.     

Regulatory focus systems and personal values

The present studies sought connections between two highly influential, but separate motivational systems: the regulatory foci and personal values. Study 1 (N = 173) showed that promotion focus was positively associated with Achievement and negatively with Tradition values, whereas prevention focus was positively associated with Conformity and Security values, and negatively with Self‐Direction and Stimulation values. Furthermore, interdependent self‐construal moderated trait prevention focus' associations with Power, Benevolence, Universalism, and Conformity values. Study 2 (N = 150) showed that a promotion‐framed message evoked more compliant behavior among those scoring high on Stimulation, Achievement, and Self‐Direction values, but that a prevention‐framed message evoked more compliance among those high in Conformity values. The results suggested that the regulatory foci are associated with certain values, and that these values may increase motivation in promotion‐ versus prevention‐relevant situations.

Vigilance decrement during a simulated general aviation flight

This study examined pilots' vigilance during an extended general aviation flight as measured by their capacity to exercise control over the aircraft during a planned flight. Thirty‐one qualified pilots flew a flight simulator from Wagga Wagga to Bankstown, Sydney, a distance of 207 nautical miles. The flight comprised five separate legs, although three legs were subjected to analysis. On the basis of attentional resource theory, it was hypothesised that task performance would differ based on the requirement for memory retrieval. Consistent with the hypothesis, the results revealed a deterioration in those tasks for which there was a substantial requirement for memory retrieval. Further analysis revealed that the deterioration in performance was best predicted by pilots' perception of the workload associated with the flight and their perception of their ability to exercise control over aircraft during normal conditions. The implications are discussed in terms of system design and training. Copyright © 2010 John Wiley & Sons, Ltd.     

A Model of Online Protection to Reduce Children’s Online Risk Exposure: Empirical Evidence From Asia

Children are surrounded by a variety of digital media and are exposed to potential risks that come with such easy accessibility. Learning how to be safe online is an important consideration for both children and their caregivers. The present study proposes an integrated model of online safety based on constructs from protection motivation theory and the health belief model, namely perceived severity of (and susceptibility to) risk, online self-efficacy, online privacy concern, and digital literacy. The study comprised a survey conducted among 420 schoolchildren aged 9–16 years. Using partial least squares-structural equation modelling, the results illustrated the presence of a negative effect of ‘perceived severity of online risk’ toward online risks, whereas the effect of ‘digital literacy’ was found to be positive. Children whose perception of online risks was more severe were less exposed to online risks if they had higher ‘online privacy concerns’ than the children with higher ‘digital literacy’ who are more exposed to online risk. Results of the study show that engaging in safe online behaviour requires children to have a high perception regarding severity of online risks as well as knowledge of online privacy concerns. Online risks and opportunities occur in parallel. Consequently, the factors that increase or decrease risk may also increase or decrease the benefits.     

Understanding the past: Investigating the role of availability,outcome, and hindsight bias and close calls in visual pilots' weather‐related decision making

Past events, such as “close calls,” can provide valuable learning opportunities, especially in aviation, where learning from past errors could potentially help to avoid future incidents or accidents. This study investigated whether three cognitive biases (availability, outcome, and hindsight bias) could influence pilots' perceptions of past events, which in turn might influence their perception of events yet to occur. Study 1 found that pilots were influenced by the outcome of a flight when judging decision quality. Of particular interest was that pilots interpreted events that led to a close call very similarly to those that had positive outcomes, which may reinforce risky behaviour. However, although adequately powered, Study 1 found no evidence of availability bias: Exposure to one of four outcomes did not appear to influence later decisions. Study 2 found that having read a flight report, particularly if it ended in a crash, pilots consistently overestimated their likelihood of predicting the actual outcome, which may reduce any opportunity to learn. These findings suggest that two of the three cognitive biases explored in this study could influence a pilot's perception of past events in ways that may adversely affect how they make future decisions that in turn may affect flight safety.     

Optimism and Attributional Retraining: Longitudinal Effects on Academic Achievement,Test Anxiety,and Voluntary Course Withdrawal in College Students1

A longitudinal study examined how optimism and attributional retraining (AR) influenced 256 first‐year college students' test anxiety, cumulative academic achievement, and course persistence in college over an academic year. Students' optimism was assessed at the start of the academic year and they were assigned to either an AR or no‐AR (control) condition. Measures of students' test anxiety, cumulative grade point average, and voluntary course withdrawal were obtained at the end of the academic year. Results suggest that although high optimism was an academic risk factor among students who did not receive AR, high‐optimism students who did receive the AR cognitive intervention benefited from its effects to a greater extent than did low‐optimism students.     

Testing the limits of optimistic bias: event and person moderators in a multilevel framework

N. D. Weinstein (1980) established that optimistic bias, the tendency to see others as more vulnerable to risks than the self, varies across types of event. Subsequently, researchers have documented that this phenomenon, also known as comparative optimism, also varies across types of people. The authors integrate hypotheses originally advanced by Weinstein concerning event-characteristic moderators with later arguments that such optimism may be restricted to certain subgroups. Using multilevel modeling over 7 samples (N = 1,436), the authors found that some degree of comparative optimism was present for virtually all individuals and events. Holding other variables constant, higher perceived frequency and severity were associated with less comparative optimism, higher perceived controllability and stereotype salience with more comparative optimism. Frequency, controllability, and severity were associated more with self-risk than with average-other risk, whereas stereotype salience was associated more with average-other risk than with self-risk. Individual differences also mattered: comparative optimism was related negatively to anxiety and positively to defensiveness and self-esteem. Interaction results imply that both individual differences and event characteristics should jointly be considered in understanding optimistic bias (or comparative optimism) and its application to risk communication.     

Reducing optimism bias in the driver’s seat: Comparing two interventions

Optimism bias combined with sensation-seeking and risky driving have been proposed to be the main contributing factors to young drivers’ involvement in road traffic collisions. The present study aimed to evaluate how two brief interventions, one based on an unambiguous definition of “good” driving and the other on a hazard perception test, might reduce young drivers’ optimism bias. One hundred and twenty-eight university students were randomly allocated to one of three groups: standard definition, hazard perception or control. Measures evaluating optimism bias were completed before and after the intervention, and questions regarding their sensation-seeking and past risk-taking tendencies were asked at follow-up. Both brief interventions reduced optimism bias levels, but hazard perception had the strongest effect. The effectiveness of the two interventions also differed across individuals depending on their sensation-seeking and past risky driving tendencies. The results provide evidence for the effectiveness of brief interventions to reduce optimism bias.     

Measuring optimism bias among military personnel

High numbers of young military personnel die due to road traffic collisions (RTCs). Yet, there is a paucity of research related to the contributing factors (i.e., optimism bias and willingness to take risks) associated with RTCs and the examination of road safety education program tailored at reducing young military fatalities. In order to address this gap in the literature, we examined one specific road safety educational intervention tailored for the UK military personnel and investigated their attitudes towards the program, optimism bias and willingness to take risks. Measures evaluating their optimism bias, willingness to take risks and attitudes towards the program were asked after the participants attended the road safety interventions. The results revealed that young military personnel, aged 18–25, had higher optimism bias and willingness to take risks compared to older military personnel, and that this effect diminishes with age. The results provide importance evidence related to military personnel’s attitudes to risk-taking.     

Optimism, promotion pride, and prevention pride as predictors of quality of life

The relationship between optimism and two potential sources of optimistic beliefs--promotion pride (based on a history of success in promotion regulation) and prevention pride (based on a history of success in prevention regulation)--was explored. Optimism was more strongly related to promotion pride than prevention pride (controlling for neuroticism), consistent with past work showing that anticipating success increases eagerness motivation but decreases vigilance motivation. This suggests that the psychology of prevention regulators is not captured well by the existing literature on optimism. Although prevention pride does not predict self-reports of well-being, it does predict adaptive functioning independent of optimism, neuroticism, and promotion pride. Promotion pride uniquely predicted a sense of purpose in life or goal directedness. Both promotion and prevention pride predicted active coping. It is argued that promotion and prevention pride tell us something unique and important about the role of successful self-regulation in determining quality of life.     

Let Go of Your (Inflated) Ego: Caring more about Others Reduces Narcissistic Tendencies

Narcissists are known for having excessively positive self‐views, but an equally defining characteristic of narcissism may be a disregard of other people. Could encouraging people to care more about others, or feel more connected to them, reduce narcissism? We describe a series of studies demonstrating that a more communal focus on others reduces narcissistic tendencies. In particular, repeating communal self‐statements (i.e., “I am a caring person”), recalling a time when one was caring, feeling empathy, focusing on monetary expenditures (which increases a sense of dependence on others), and interdependent self‐construal all situationally reduce narcissism. These effects occur on a small scale but are significant because they establish that communal focus causes changes in narcissism. They also suggest that narcissism may have a state‐like or context‐dependent component, fluctuating across time and situations. Everyone may have the propensity to be narcissistic, but caring more about others may help to curb narcissism.     

Probing the link between narcissism and gambling: the mediating role of judgment and decision‐making biases

In this paper, three studies link narcissism to gambling in general, and gambling‐related problems in particular, and the predictive link is shown to be mediated by judgment and decision processes. In Study 1, we demonstrate that narcissism relates to greater self‐reported gambling frequency and gambling‐related monetary expenditures in two samples. We extend these initial findings in Study 2 by showing that narcissism predicts higher reports of gambling‐related pathology, as measured with a DSM‐IV‐based pathological gambling (PG) screen. Finally, we demonstrate in Study 3 that the link between gambling pathology and narcissism is partially mediated by narcissists' overconfidence, heightened risk acceptance, and myopic focus on reward, as measured by participants' behavioral performance on the Georgia Gambling Task (GGT) and Iowa Gambling Task (IGT). Discussion focuses on the empirical validation of the long‐assumed narcissism–gambling link, the decision processes that underlie this link, and relations between narcissists' self‐perceptions and their self‐defeating behavior, especially in risk‐relevant contexts.
