奖赏和损失情境下男性海洛因戒断者的风险决策缺陷

摘 要 采用修改版的多伦多赌博任务考察决策情境对海洛因戒断者风险决策的影响。研究结果主要发现,海洛因戒断者在损失情境下的风险寻求决策比率与吸毒年限显著正相关,这种相关提示了风险决策背景下海洛因成瘾者持续使用毒品与其较低的损失敏感性之间的复杂交互作用。其次,海洛因戒断者在做出风险决策后收到消极反馈时的风险规避倾向可以负向预测其风险寻求决策比率,这可能进一步反映了海洛因戒断者风险感知的钝化或其对消极反馈信息的整合加工存在异常。     

道德决策快的智能机器让人更信任：能力感知的中介作用

本研究旨在探究智能机器的道德决策速度是否以及如何影响人们对其的信任程度。研究分别以智能机器与人类为道德决策主体,采用2（决策速度）×2（决策内容）的被试间设计进行研究发现,对于智能机器和人类,道德性决策均会使人们对其信任,而快速道德决策提高了人们对智能机器的信任程度;此外,研究发现能力感知是智能机器道德决策速度影响人们对其信任程度的中介机制。研究表明人们对智能机器与人类的道德决策速度知觉存在差异。     

社会价值取向对自我-他人风险决策的影响及其机制

以往关于为自己和代他人决策的冒险行为研究结果不一致,这可能是因为以往的研究没有考虑决策情境和决策者人际特质等因素对于决策行为的影响。社会价值取向(social value orientation, SVO)是一种典型的人际特质,是个体在对自我和他人资源分配时所表现出的社会偏好,通常分为亲社会者和亲自我者。为探究SVO对自我-他人风险决策的影响及其机制,采用为自己和陌生人分别完成多轮混合赌博游戏的任务。结果发现亲自我比亲社会者代他人决策更冒险。用模型量化的损失厌恶和对潜在损失的敏感度部分中介了自我-他人风险决策差异,但只有对他人潜在损失的敏感度部分中介自我-他人决策的SVO效应。说明SVO会影响自我-他人风险决策,且该效应可以通过对他人利益的关心程度起作用,所以在自我-他人风险决策的研究中应将SVO这一决策者的人际特质因素考虑在内。     

决策与决策执行的关系——一种行动理性的观点

本文以分析决策与执行的关系为出发点,对人类理性的本质进行了讨论。指出决策研究中存在的“理性分析范式”偏面地把认知分析当作人类理性的本质,忽视了行动的作用,提出了人类理性是“行动理性”的思想。行动既是一种分析方法,是人们深化对客观世界的认识,理解决策问题的独特手段,也是人们创造外界环境、实现决策目标的有效途径。由此提出,决策研究,尤其是组织决策研究,应该重视“行动分析范式”。     

医患共同决策的具象问题思考——以肺结节诊疗为例

随着健康体检观念的深入及低剂量CT的广泛开展,肺结节的检出率大大提高,而对于其诊断及治疗方案的选择则具有较多的争议,过度诊疗或重视不足都会对患者造成伤害,如何做到正确的诊治从而保证患者的权益,患者的参与及接受程度显得十分重要,医患共同决策(shared decision making,SDM)这一方式在肺结节诊疗过程中的作用不言而喻。通过相关案例初步探索SDM在肺结节诊疗过程中的应用及效果,从而为临床医生及肺结节患者在诊疗过程中提供一种新的思路,也期望这种模式能够得到医患双方的共同认可,减少临床决策中的医患冲突,取得更佳的治疗方案。     

金钱刺激和决策者角色对个体道德决策的影响——基于过程分离范式

以大学生为被试,采用3（金钱刺激：无金钱刺激、金钱奖励、金钱惩罚）×2（决策者角色：决策者、旁观者）的被试间实验设计,利用过程分离范式分别计算被试道德决策中的功利主义倾向和道义论倾向,从而探讨金钱刺激和决策者角色对个体道德决策的影响。结果发现：（1）无论是决策者还是旁观者,金钱刺激都不会影响其道义论倾向;（2）决策者的道义论倾向大于旁观者;（3）只在有金钱奖励时决策者的功利主义倾向才大于旁观者。     

The Privacy of Tutankhamen – Utilising The Genetic Information In Stored Tissue Samples

Recent technical developments in genetictesting has led to a situation where the DNA inpreviously stored tissue samples can beextracted and used for genetic analysis. Thisraises the question of how to decide whether aspecific use of such samples should be allowed.Using the genetic testing of ancient DNA ingeneral, and the DNA of the pharaoh Tutankhamenin particular as examples this paper analysesthe question. It investigates whether ethicalframeworks based on proxy consent, culturalaffiliation, ownership, or the privacy rightsof the dead are appropriate and justifiable inthis context. The conclusion is that frameworksbased on proxy consent, cultural affiliation,and ownership are not very useful.     

Surviving Toward College Graduation

This 5-year longitudinal study with a diverse sample of 405 graduating high school seniors examined the person, behavior, and environment (PBE) factors that increased student chances of deciding to attend a 2- or 4-year college, enrolling in college the fall semester immediately following high school graduation, and then returning to that same college a year later as a retained college student. Survivability across these three critical college-going transitions was a function of two different kinds of PBE patterns. First, certain PBE factors played prominent roles at specific transition points and then more minor support roles at others. Second, several factors provided consistent support at each transition point without being the primary determiner of success at any single transition. Students are more likely to succeed in college if school counselors help them to learn and take advantage of those PBE patterns that promote postsecondary success.     

Parental decision-making: infant engagement with smartphones

Smartphones have become a ubiquitous part of life, and as a result, many children are engaging with smartphones beginning in infancy. Little is known regarding the thought processes used by parents in deciding when and how to allow their infants to engage with smartphones. Using a sample of twelve parents with infants younger than one year, this qualitative study examines parental smartphone use, their perspectives regarding use by their young children, and what sources informed their decision-making about allowing their infants to use a smartphone. Results found that the smartphone has become such a common part of everyday life that choices to use a smartphone around, and with, infants has become one that is nearly automatic. These research data showed that most parents are largely unaware of guidelines for childhood screen time provided by the American Academy of Pediatrics and the World Health Organization. Given our current knowledge that smartphone use can have a significant impact on the cognitive development of young children, this topic is an important area of future research.     

智能医学算法决策的伦理困境及风险规制

智能医学呈现出难追溯性、不公平性、过程难以理解性、结果不确定性和数据驱动性的技术特征。上述特征与诊疗场景特性的融合交叠可能诱发医生主体地位被削弱、医患信任危机、医疗资源分配不均加剧以及诊疗结果不确定性增加等风险。为有效防范智能算法的决策风险,在智能医学应用中必须遵循以强化医生主体地位为根本出发点,以降低医患信任危机为主导,以平衡资源分配为方向和以增加诊疗结果确定性为目标的伦理规制。
