Our actions, individually and collectively, inevitably affect others, ourselves, and our institutions. They shape the people
we become and the kind of world we inhabit. Sometimes those consequences are positive, a giant leap for moral humankind. Other
times they are morally regressive. This propensity of current actions to shape the future is morally important. But slippery
slope arguments are a poor way to capture it. That is not to say we can never develop cogent slippery slope arguments. Nonetheless,
given their most common usage, it would be prudent to avoid them in moral and political debate. They are often fallacious
and have often been used for ill. They are normally used to defend the moral status quo. Even when they are cogent, we can always find an alternate way to capture their insights. Finally, by accepting that the
moral roads on which we travel are slippery, we become better able to successfully navigate them. 相似文献

Research on willingness to make marginal investments (e.g., the escalation and sunk cost literatures) has often focused on project completion decisions, such as the “radar‐blank plane.” This paper discusses a fundamentally different type of marginal investment decision, that of couples deciding whether to continue infertility treatment in the face of repeated failures. Two experiments based on this context show that when people face multiple independent chances to achieve a valued goal but are unsure about chances of success, premature quitting or “de‐escalation” is the norm. Repeated negative feedback appears to induce individuals to see each successive failure as more and more diagnostic. As a result, even a short series of failed attempts evokes beliefs that future attempts will also fail. These emergent expectations of failure, generated by causal attribution processes, associative learning, and/or discounting of ambiguous information, appear very compelling and induce people to forgo profitable marginal investments.

该研究以某985高校550名硕士毕业生为样本,编制、修订了相关问卷或量表,通过数据分析探讨了就业压力源对就业过程产生的负性情绪的直接效应及人格、情绪调解策略等中介变量的效应。结果发现,就业压力源、神经质性对负性情绪有显著直接效应,就业压力源通过人格的神经质性维度对负性情绪产生显著间接效应;神经质性的影响程度大于就业压力源的影响程度。关于负性情绪,未发现情绪调节策略对其有显著的直接效应或中介效应。 相似文献

This study evaluated a device that applied a sustained increase in accelerator pedal back force whenever drivers exceeded a preset speed criterion without buckling their seat belts. This force was removed once the belt was fastened. Participants were 6 commercial drivers who operated carpet-cleaning vans. During baseline, no contingency was in place for unbuckled trips. The pedal resistance was introduced via a multiple baseline design across groups. On the first day of treatment, the device was explained and demonstrated for all drivers of the vehicle. The treatment was associated with an immediate sustained increase in seat belt compliance to 100%. Occasionally, drivers initially did not buckle during a trip and encountered the force. In all instances, they buckled within less than 25 s. These results suggest that the increased force was sufficient to set up an establishing operation to reinforce seat belt buckling negatively. Drivers indicated that they were impressed with the device and would not drive very long unbelted with the pedal force in place. 相似文献

We observed 11 undergraduates in an experiment designed to simulate infant caregiving. In negative reinforcement conditions experienced by all participants, a targeted caregiving response (e.g., rocking a baby doll) produced escape from, and avoidance of, a recorded infant cry. Nine participants' caregiving was shown to be controlled by this negative reinforcement contingency. Nine participants experienced an extinction condition that consisted of an inescapable cry, and the previously reinforced caregiving responses of 2 of these participants were resistant to extinction. For both of these participants, the previously reinforced response was eliminated when an alternative form of caregiving was reinforced. These results highlight the role of negative reinforcement in infant caregiving and suggest the need for additional research on the effects of crying on caregivers as well as the development of effective strategies for minimizing infant crying. 相似文献

本文根据埃里克森、玛西娅、加藤厚等人的自我同一性理论,对某中学初一至高三学生的自我同一性及情绪表达进行问卷调查研究。研究发现,中学生自我同一性发展各个维度总体呈"低-高-低-高"的发展趋势。高一是自我同一性发展的转折时期,在现在的自我投入上处于低谷,与其他各年级存在显著性差异。同时自我同一性度数分布也存在显著性差异。中学生的正性情绪表达在性别上存在显著差异。从初一至高三,学生的情绪表达三个维度都呈下降趋势,高二、高三学生的正性情绪表达、负性情绪表达、情绪表达强度显著低于初一、初二学生。中学生现在的自我投入和将来自我投入的愿望与正性情绪表达呈显著正相关。 相似文献
