Some environmental ethicists and economists argue that attributing infinite value to the environment is a good way to represent an absolute obligation to protect it. Others argue against modelling the value of the environment in this way: the assignment of infinite value leads to immense technical and philosophical difficulties that undermine the environmentalist project. First, there is a problem of discrimination: saving a large region of habitat is better than saving a small region; yet if both outcomes have infinite value, then decision theory prescribes indifference. Second, there is a problem of swamping probabilities: an act with a small but positive probability of saving an endangered species appears to be on par with an act that has a high probability of achieving this outcome, since both have infinite expected value. Our paper shows that a relative (rather than absolute) concept of infinite value can be meaningfully defined, and provides a good model for securing the priority of the natural environment while avoiding the failures noted by sceptics about infinite value. Our claim is not that the relative infinity utility model gets every detail correct, but rather that it provides a rigorous philosophical framework for thinking about decisions affecting the environment.  相似文献

Philosophy makes no progress. It fails to do so in the way science and mathematics make progress. By “no progress” is meant that there is no successive advance of a well‐established body of knowledge—no views are definitively established or definitively refuted. Yet philosophers often talk and act as if the subject makes progress, and that its point and value lies in its doing so, while in fact they also approach the subject in ways that clearly contradict any claim to progress. This article presents evidence for, and a theoretical explanation of, the view that philosophy makes no progress, concluding with an account of what philosophy is and what the point and value of it is. Philosophy should not be shy about being what it is, nor should it pretend to be what it is not. What it is should be reflected in philosophizing and the way it is taught.  相似文献

The concept of reinforcement value summarizes the effect of different variables, such as reinforcement delay, reinforcement magnitude, and deprivation level, on behavior. In the present set of experiments, we evaluated the effect of reinforcement devaluation on performance under FI schedules. The literature on timing and reinforcement value suggests that devaluation generates longer expected times to reinforcement than the same intervals trained under control conditions. We devalued reinforcement with delay in Experiments 1A, 1B, and 2, and diminished deprivation in Experiments 3A and 3B. Devaluation reduced response rates, increased the number of one‐response intervals, and lengthened postreinforcement pauses, but had inconsistent effects on other timing measures such as quarter life and breakpoint. The results of delayed reinforcement and diminished deprivation manipulations are well summarized as reinforcement devaluation effects. These results suggest that devaluation may reduce stimulus control. In addition, we argue that the process by which delayed reinforcement affects behavior might also explain some effects observed in other devaluation procedures through the concept of reinforcement value.  相似文献

We investigated whether lines and shapes that present face-like features would be associated with emotions. In Experiment 1, participants associated concave, convex, or straight lines with the words happy or sad. Participants found it easiest to associate the concave line with happy and the convex line with sad. In Experiment 2, participants rated (valence, pleasantness, liking, and tension) and categorised (valence and emotion words) two convex and concave lines that were paired with six distinct pairs of eyes. The presence of eyes affected participants’ valence ratings and response latencies; more congruent eye–mouth matches produced more consistent ratings and faster reaction times. In Experiment 3, we examined whether dots that resembled eyes would be associated with emotional words. Participants found it easier to match certain sets of dots with specific emotions. These results suggest that facial gestures that are associated with specific emotions can be captured using relatively simple shapes and lines.  相似文献

In today’s competitive environment, salespeople are challenged with creating customer value in an ethical manner while meeting performance goals. Sales supervisors play a critical role in ensuring that this challenge is met. This research examines the roles of psychological ethical climate and leader–member exchange (LMX) in encouraging salespeople’s commitment to providing superior customer value, reducing their unethical intentions and improving sales performance. Results indicate that business-to-business salespeople’s psychological ethical climate perceptions influence their perceived relationship with their sales supervisor (i.e. LMX relationship) as well as their commitment to providing superior customer value. LMX also directly influences commitment to providing superior customer value, which in turn affects salespeople’s unethical intent and quota performance. Theoretical and managerial implications based on the study’s findings are provided, as well as directions for future research.  相似文献

The claim that humans adapt their actions in ways that avoid effortful processing (whether cognitive or physical) is a staple of various theories of human behavior. Although much work has been carried out focusing on the determinants of such behaviors, less attention has been given to how individuals evaluate effort. In the current set of experiments, we utilized the general evaluability theory to examine the evaluability of effort by examining subjective value functions across different evaluation modes. Individuals judged the anticipated effort of four task‐specific efforts indexed by stimulus rotation, items to be remembered, weight to be lifted, and stimulus degradation across joint (i.e., judged comparatively) and single evaluation modes (i.e., judged in isolation). General evaluability theory hypothesizes that highly evaluable attributes should be consistently evaluated (i.e., demonstrate similar subjective value functions) between the two modes. Across six experiments, we demonstrate that the perceived effort associated with items to be remembered, weight to be lifted, and stimulus degradation can be considered relatively evaluable, while the effort associated with stimulus rotation may be relatively inevaluable. Results are discussed within the context of subjective evaluation, internal reference information, and strategy selection. In addition, methodological implications of evaluation modes are considered.

Value From Regulatory Fit   总被引:9,自引:0,他引:9  
Abstract— Where does value come from? I propose a new answer to this classic question. People experience regulatory fit when the manner of their engagement in an activity sustains their goal orientation or interests regarding that activity. When there is fit, people engage more strongly in what they are doing and "feel right" about it. Fit influences the strength of value experiences—how good or how bad one feels about something—independently of the pleasure and pain experiences that are associated with outcomes. It uniquely contributes to people's experience of the value of things. Fit is shown to influence judgments and decision making, attitude and behavior change, and task performance.  相似文献

价值观与大学生寻求社会支持的关系研究   总被引:10,自引:0,他引:10  
游洁 《心理科学》2005,28(3):713-717
在大学学习阶段,各种青年期不可避免的问题和大学生所特有的紧张与压力极大地影响着大学生的健康成长。尽管家长、同学、老师和朋友都可能为他们提供有效的社会支持与帮助,然而他们在遇到困难或烦恼时却很少主动寻求帮助,造成这种现象的原因是多方面的,如个体需要帮助的原因,个人价值观、对自我的评价、对帮助者意图的分析等,本文主要研究和探讨了价值观对大学生寻求社会支持与帮助的影响,并初步揭示了它们之间的相互关系。  相似文献

本研究采用汉化的Schwartz《肖像价值观问卷》(2012)测量了2569人的大样本,以验证Schwartz新价值观理论及其工具在中国的适用性及中国人价值观结构特点。结果表明,19种价值观内部一致性系数平均为0.66,范围从“支配权力”价值观的0.54到“社会安全”价值观的0.80,验证性因素分析各项指标均达到可接受水平;中国人个人定向类价值观之间的相关关系与原理论假设不相符合;个人定向类和社会定向类价值观之间,出现了多项位置相对、在原理论中假定为低相关的价值观呈高相关关系。表明Schwartz等(2012)价值观理论虽从测量学角度适用中国人群,但其不能预测和解释中国人价值观的“个人”与“社会”辩证统一与交叉融合特点。  相似文献
