The Relatively Infinite Value of the Environment

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.     

Philosophy Makes No Progress,So What Is the Point of It?

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.     

Reinforcement value and fixed‐interval performance

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.     

Psychological ethical climate,leader–member exchange and commitment to superior customer value: influencing salespeople’s unethical intent and sales performance

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.     

Evaluating Effort: Influences of Evaluation Mode on Judgments of Task‐specific Efforts

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

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.

对心理咨询中价值干预问题的理性思考

对价值问题的处理是心理咨询中的重要哲学命题.人本主义心理学所遵循的"价值中立"原则,是心理咨询中回避价值干预的根源所在.通过对心理咨询理论的整体审视,提出不能简单地把价值中立原则拓展到整个心理咨询之中,不能忽视心理咨询的教育功能和社会责任,纯粹的"价值中立"是无法实现的.
