Self-Other Discrepancies in Waiting Time Decisions

Both anecdotal evidence and recently reported research suggest that people are risk-averse when faced with waiting time decisions. Four studies investigate whether there is a self-other discrepancy in how people make waiting time decisions themselves and how they predict others will make similar decisions. People are found to believe that others have valuations of time similar to their own. However, when faced with alternatives that involve risk in the duration of the wait, the results point to a self-other discrepancy, in that people report greater risk-aversion themselves than they think others would. Further, when faced with waiting time gains, people are themselves more risk-averse than they think others would be. Conversely, when faced with waiting time losses, people are themselves more risk-seeking than they think others would be. Overall, the results are consistent with the recently proposed risk-as-feelings hypothesis.     

Why Young Men Drive Dangerously: Implications for Injury Prevention

Why is risk consistently underestimated, and why do young men in particular take exceptionally high risks and think of themselves as invulnerable? Two explanatory paths are proposed. The first is that risk taking in young males has been shaped by evolutionary forces to provide a fitness value. The second pathway is through myth and the other narrative forms that affirm the ego's immortality and invulnerability. Because of its evolutionary base, risk taking is emotionally driven: Emotions are preverbal and irrational, which means that persuasive prevention cannot be more than weakly successful. Three prevention challenges emerge from this analysis: to determine what it is that young drivers fear, to attach affectively experienced fears to defined driving behaviors, and to devise injury-prevention programs that acknowledge that young males' risk taking is not "stupid," but driven by adaptive needs that are as significant to today's young adults as they were to our distant ancestors.

A study of emotion and reason in products and services

This study investigates the relationship between emotion, reason and perceived risk. Evidence is presented using an aggregative data set of 146 products and services which were randomly selected from the SIC (Standard Industrial Classification Codes) manual. It is demonstrated that emotional factors account for a significant and substantial portion of the variance in perceived risk even after the effect of rational factors (perceived differences between alternatives) has been taken into account. It is suggested that emotion be explicitly modelled in future conceptualisations of perceived risk. Copyright © 2002 Henry Stewart Publications.     

Risk perception and risky choice: Situational, informational and dispositional effects

We investigated how situational (gain–loss), informational (opportunity–threat framing) and dispositional (achievement motive and avoidance motive) variables affected opportunity–threat perception and risky choice in managerial decision-making contexts. In Study 1, the risk preference of the participants showed a reflection effect due to situational differences (gain or loss) and a partial framing effect caused by presenting the same choice information in terms of either opportunities or threats. However, both effects were in the opposite direction of predictions from prospect theory. Gains and positive framing enhanced risk-seeking preference whereas losses and negative framing augmented risk-averse preference. Risk-seeking choices were mediated by opportunity perception whereas risk-averse choices were mediated by threat perception. In Study 2, the participants high in achievement motive perceived greater opportunities in a negative situation, and the participants high in avoidance motive perceived greater threats in a positive situation, suggesting that ambition (achievement motive) operates more significantly in the face of adversities whereas cautiousness (avoidance motive) functions more significantly in prosperity.     

Effects of short‐term cosmetic versus long‐term health fear appeals in anti‐smoking advertisements on the smoking behaviour of adolescents

A field study exposed 235 high school students to anti‐smoking advertisements over a five‐month period to test the effectiveness of short‐term cosmetic versus long‐term health fear appeals in preventing or reducing smoking. The study was a longitudinal experiment with two experimental groups and a control group. Smoking behaviour was measured prior to message exposure on television, in magazines and on the internet, and at the end of the study period. The primary results were that average smoking declined for subjects exposed to either type of anti‐smoking fear appeal but not for the control group and short‐term cosmetic fear appeals were more effective for males but long‐term health fear appeals were more effective for females.

Habituation in high‐risk infants: reliability and patterns of responding

We examined both the reliability of infant‐controlled habituation and patterns of responding in a group of high‐risk infants (mean age 16 mos). Good test–retest reliability was found for mean, total, and baseline looking time for one of the stimuli. Classification of infants' pattern of performance yielded two groups: linear (57%) and non‐linear (29%) responders; 14% of cases could not be classified because of cross‐session inconsistencies in performance. Linear responders had shorter total looking times, fewer trials to criterion, and showed more habituation than non‐linear responders, thus validating the linear/non‐linear distinction. Our findings indicate that the infant‐controlled habituation task can be used reliably with infants who are at high risk for developmental disorders. Indeed, we provide evidence that this task is not only reliable, but may also provide meaningful distinctions between infants within the high‐risk population. Discussion focuses on the role of attention in distinguishing between short (linear) and long (non‐linear) lookers. Copyright © 2003 John Wiley & Sons, Ltd.     

Intergenerational studies of parenting and the transfer of risk from parent to child

This review describes a recent approach to studying the intergenerational processes that place families and children at risk for a broad variety of social, behavioral, and health problems. Intergenerational studies typically involve two (or more) generations of participants, observed over time. These projects are utilized to study the origins and early determinants of parenting behavior and of other environmental, health, and social conditions that place young offspring at risk for continuing behavioral, cognitive, and health problems. Convergent findings, across a broad range of research populations in several countries, suggest that problematic parenting develops in part through learning the behavior modeled by one's own parents. In addition, problematic parenting seems to be an extension of an individual's early style of aggressive and problematic social behavior. Parents with a history of childhood aggression, in particular, tend to have continuing social, behavioral, and health difficulties, as do their offspring. Conversely, parental involvement, cognitive stimulation, warmth, and nurturance appear to have important protective effects for offspring. Finally, educational achievement appears to be a powerful buffer against problematic parenting and a wide variety of difficult family circumstances, protecting families against the transfer of risk between generations.     

自我保护性医疗的伦理扫描--论患方知情同意与医方规避风险

自我保护性医疗是近年来医方为应对医患关系重构而采取的一种行为模式,其本身和影响具有全新特点,充满价值冲突;这种行为模式,客观上是对应医疗风险尤其是重大医疗风险的;主观上同医方免责期待的张扬以及对知情同意的解读直接相关;因而,正当的自我保护性医疗既取决于医方合理的免责期待,以及改变对知情同意的误读,更依赖于自身的医学伦理综合素质的打造和完善。     

医疗风险防范与化解新趋向

新的《医疗事故处理条例》实施以后,患者的自我保护意识不断增强、高精尖医疗器械的应用、新技术的不断开展等均增加了医疗行为的风险,医疗风险管理显示出日益重要的作用。新形势下医疗风险管理的新趋向是建立自愿的医疗责任保险、组织患者参加医疗风险保险、建立强制性医疗责任保险制度、卫生行政部门代理保险业务、建立医疗援助基金等方式,提出了在风险控制的基础上,加强风险融资的措施。
