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.     

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。     

Longitudinal interplay of young children's negative affectivity and maternal interaction quality in the context of unequal psychosocial resources

Interaction quality and child temperament predict early and later child development. Research hints at transactional interrelations of both aspects but lacks adequate data to examine this assumption. Maternal psychosocial resources are suspected moderators in this context but rarely taken into account. Drawing on data of the German National Educational Panel Study we conducted a cross-lagged panel analysis on the longitudinal interplay of maternal interaction quality and children's negative affectivity at 6–8, 16–18, and 25–27 months and compared mothers with and without accumulated strains. Both variables showed moderate to high structural and rank order stability over time and low but increasing connections. In the case of accumulated stress factors, interaction quality is clearly impaired and high negative affectivity acts as an additional burden while low negative affectivity helps strained mothers to maintain higher interaction quality but only in the first year of life.     

Risky behavior in young adult pedestrians: Personality determinants,correlates with risk perception,and gender differences

Based on the risk homeostasis theory, the aim of this study was to assess acceptable risk, measured by personality factors, and risk perception, measured by physiological arousal, as predictors of risky behavior in young adult pedestrians, as well as to assess for gender differences. Eighty-two young adults, aged 18–30, completed self-report measures about risky pedestrian behaviors and these personality traits: impulsiveness, conscientiousness and openness to experience. Sixty-four of these participants then took part in an experimental task designed to assess their perception of the level of risk in situations involving different interactions between cars and pedestrians. Risk perception was assessed by these physiological responses: heart rate, skin conductance level, and skin conductance response. Results showed that risky behavior had significant correlations with impulsiveness, conscientiousness, and skin conductance level. Gender differences also emerged in risky behavior, impulsiveness, conscientiousness, and skin conductance level. Finally, a structural equation model showed that impulsiveness, conscientiousness and the difference in skin conductance level between risky and neutral situations predicted risky pedestrian behaviors, and explained 23.6% of the its variance, after controlling the effect of gender. Implications for evaluation, prevention, and intervention for risky pedestrian behaviors are discussed.     

Driving construals: Personal Construct Theory in a reckless driving context

With research revealing low road safety campaign efficacy and links between reckless driving behaviors and crash frequency, further investigation into the foundations and composition of driver education and training is required. Through two studies, the current research aimed to develop a measure that utilized the principles of Kelly’s (1955) Personal Construct Theory to (a) elicit constructs, or construals, specific to selected elements of reckless driving behaviors, (b) pilot a method in which the elicited constructs could be measured by asking participants to choose those they deemed most important, (c) group participants based on their constructs, and (d) assess between-group differences in self-reported reckless driving behavior. Results suggest that drivers can be categorized based on the constructs they use, and that rates of self-reported past engagement in reckless driving behavior, and willingness to do so in the future, vary systematically between these construal-based driver categories. Continuing research is required to develop and test applications of these findings.
