贪婪:态度、动机与决策机制

贪婪是人性的重要特点之一,也是哲学、经济学等领域经常讨论的话题.本文首先梳理了贪婪的概念,并将问题聚焦在对于物质的贪婪上.然后总结了贪婪的特点,并提出贪婪的定义.接着阐述了情境因素如何影响个体对贪婪的态度,以及贪婪动机如何影响自利行为.贪婪决策是个体决定是否做出贪婪行为的心理过程,受到自我意识和情绪的影响.贪婪决策过程模型整合了控制性、自动化两类加工方式,阐释了自利倾向与道德自觉相互作用的机制.本文对以上内容逐次进行讨论,并提出了未来研究的方向.     

病人临终决策中的自主问题辨析

自主在医学伦理学中是一个重要的概念。在临终决策中,必须对病人自主从主体自主和行为自主两个维度加以区分,并强调缺乏内外部约束的重要性,尽管内部约束对病人自主影响巨大,但它并不会破坏临终决策的行为自主。在回顾两种反对将行为自主作为理解临终决策手段的意见基础上,应当实现行为自主的标准从完全自主向充分自主的转变,充分自主的优势在于它对各种医疗环境和背景条件所表现出的适应性。根据这一标准,诸如临终病人的死亡选择并不需要完全自主,充分自主即可。

     

“为癌症患者心理赋能”的临床干预路径

“为患者心理赋能”是近年来医疗健康领域出现的一种新的积极医疗照护理念,其关注点是个体的能力而非缺陷,它强调医疗实践应该为改善健康和生活质量建立患者激励结构。首先梳理了赋能的概念发展与心理结构,随后引证多个实证研究总结出为癌症患者心理赋能的四条临床干预路径,指出医患共同决策、同伴支持、赋能教育以及认知行为压力管理的赋能价值。最后结合已有成果和研究中发现的问题,提出癌症心理赋能干预发展建议,有利于进一步开展临床研究和实践探索。

     

患者决策能力与风险相关标准

患者决策能力对于患者享有临床知情同意权具有重要意义。风险相关标准主张决策所需的能力水平应该根据决策的结果来调整,单一的决策能力标准是不够的。决策结果带来的风险越大,能力水平要求越高,反之则可以要求较低的能力水平。该主张的伦理本质是不合理家长主义,并且,它意味着对同一决策任务,个体可能只有同意的能力而没有拒绝的能力,因而在经验上也站不住脚。患者决策能力标准仅应根据决策本身的复杂性和难易程度视该决策特性来决定,而独立于患者实际决策结果。     

叙事医学反思性写作对共同决策价值探析

以叙事医学工具反思性写作为切入点,首先从医方、患方及外部环境三个角度分析了当前医患共同决策所面临的临床实践困境,其次在对反思性写作概念、实践特点概述的基础上,提出了叙事能力对临床工作的重要性、叙事医学伦理对决策困境的作用,最后从促使医方自我反思,避免引导式决策及权威主义;弥合医患视阈差异,达成决策共识;阐明并澄清患者偏好及价值观,促进个体化共同决策;提高患者参与决策意愿,调动参与决策积极性;缓和医患关系,实现医患共情,促进共同决策良性互动五个方面阐述了反思性写作对医患共同决策困境的助力作用。

     

Support for distracted driving laws: An analysis of adolescent drivers from the Traffic Safety Culture Index from 2011 to 2017

IntroductionAdolescent drivers are often the focus of traffic safety legislation as they are at increased risk for crash-related injury and death. However, the degree to which adolescents support distracted driving laws and factors contributing to their support are relatively unknown. Using a large, nationally weighted sample of adolescent drivers in the United States, we assessed if perceived threat from other road users’ engagement in distracted driving, personal engagement in distracted driving behaviors, and the presence of state distracted driving laws was associated with support for distracted driving laws.MethodsThe sample included 3565 adolescents (aged 16–18) who participated in the Traffic Safety Culture Index survey from 2011 to 2017. A modified Poisson regression model with robust errors was fit to the weighted data to examine support for distracted driving laws. Models included age, gender, year, state distracted driving laws, personal engagement in distracted driving behavior, and perceived threat from other road users’ engaging in distracted driving.ResultsApproximately 87% of adolescents supported a law against texting and emailing compared to 66% who supported a universal handheld cellphone law. Support for distracted driving legislation was associated with greater perceived threat of other road users engaging in distracted driving while accounting for personal engagement in distracted driving, state distracted driving laws, and developmental covariates.DiscussionGreater understanding of the factors behind legislative support is needed. Public health interventions focused on effectively translating the risks of cellphone use while driving and effective policy will further improve the traffic safety culture.     

Too bored for sports? Adaptive and less-adaptive latent personality profiles for exercise behavior

Physical exercise is an effective tool for improving public health, but the general population exercises too little. Drawing on recent theorizing on the combined role of boredom and self-control in guiding goal-directed behavior, we test the hypothesis that individual differences in boredom and self-control differentiate high from low exercisers. The role of boredom as a non-adaptive disposition is of particular interest, because research on boredom in sports is scarce. Here, we investigate the role of such individual differences in self-reported weekly exercise behavior (in minutes) in a sample of N = 507 participants (n = 200 female, M_age = 36.43 (±9.54)). We used the robust variant of Mahalanobis distance to detect and remove n = 51 multivariate outliers and then performed latent profile analysis to assess if boredom (boredom proneness; exercise-related boredom) and self-control (trait self-control; if-then planning) combine into identifiable latent profiles. In line with theoretical considerations, the Bayesian Information Criterion favored a solution with two latent profiles. One profile was characterized by higher-than-average exercise-related boredom and boredom proneness and lower-than-average self-control and if-then planning values. This pattern was reversed for the second profile. A one-sided Bayesian two-sample t-test supported the hypothesis that the first profile is associated with less exercise behavior than the second profile, BF = 16.93. Our results foster the notion of self-control and if-then planning as adaptive dispositions. More importantly, they point to an important role of boredom in the exercise setting: exercise-related boredom and getting easily bored in general are associated with less exercise activity. This is in line with recent theorizing on boredoms' and self-controls’ function in guiding goal-directed behavior.
