Social influence on physics and mathematics: local or attributive?

Summary  The article is devoted to the nature of science. To what extent are science and mathematics affected by the society in which they are developed? Philosophy of science has accepted the social influence on science, but limits it only to the context of discovery (a “locational” approach). An opposite “attributive” approach states that any part of science may be so influenced. L. Graham is sure that even the mathematical equations at the core of fundamental physical theories may display social attributes. He has used the investigations of the famous Soviet physicist V. Fock on the General Theory of Relativity which were under the influence of Marxism. The Goal of the article is to demonstrate: 1) Why Soviet science is not an appropriate subject-matter for testing the thesis of social constructivism, 2) That differnt levels of science and different stages in the development of science undergo social influences in different degrees ranging from very significant and unavoidable to absolutely trivial and easy eliminated.

睾酮对价值加工的影响——基于“累积前景”理论框架的决策行为研究

较多研究支持睾酮和决策中的风险寻求行为呈正相关,但是也有其他的研究未能发现这种关系。基于决策的累计前景理论,本研究使用动态估计参数估计任务(DEEP),结合计算模型的方法,对120名双盲给药、有安慰剂对照的被试进行睾酮对价值加工过程作用的探究。结果显示,睾酮减少了个体的概率扭曲以及增加了损失规避,但是没有引发明显的风险寻求行为,研究结果表明睾酮对个体的价值加工过程产生了影响,使个体对概率的感知更接近于客观值并且增加了对损失的敏感性。     

前景理论能否解释花生瓣形效应

为了探讨前景理论能否解释花生瓣形效应(一种风险倾向随决策所涉金额大小而发生变化的效应),研究构建了4个风险概率结构相同但金额大小不同的一系列决策任务,并同时设计两种不同角度的参照点探测任务,以考察博弈活动所花时间的价值或获得情境下对获得的一般期望值能否作为前景理论的参照点,进而使得花生瓣形效应为前景理论所解释。结果发现,以一般期望值为参照点时,前景理论可以对花生瓣形效应作出比较好的解释,但博弈活动所花时间价值不可。     

Revisiting the Gain–Loss Separability Assumption in Prospect Theory

A fundamental assumption of prospect theory is gain–loss separability (GLS)—the assertion that the overall utility of a prospect can be expressed as a function of the utilities of its positive and negative components. Violations of GLS may potentially limit the generalization of results from studies of single‐domain prospects to mixed prospects and systematically distort the predictions of the theory. Violations also have implications for how choices with positive and negative components should be presented to decision makers. Previous studies, using different elicitation methods, have documented different rates, and types, of systematic violations of GLS. We discuss the differences between two specific elicitation methods—binary choice and certainty equivalents—and report results of a new study of GLS using both methods and randomly generated prospects. We compare the extent and nature of GLS violations under the two elicitation methods using between‐subject and within‐subject analyses. We find (i) systematic violations of GLS under both methods, (ii) higher rates of violations under choice, (iii) higher sensitivity to the outcomes for the certainty equivalents, which is consistent with the predictions of the scale‐compatibility hypothesis, and (iv) different patterns of violations under the two methods, which are explained by method‐specific preferences. We discuss the psychological mechanisms underlying the findings and the implications for presenting information with gain and loss components. Copyright © 2012 John Wiley & Sons, Ltd.

Voice and Culture: A Prospect Theory Approach

The present study examines the congruence of individuals' minimum preferred amounts of voice with the prospect theory value function across nine countries. Accounting for previously ignored minimum preferred amounts of voice and actual voice amounts integral to testing the steepness of gain and loss functions explicated in prospect theory, we use curve fitting to show that ratings of procedural justice fit prospect theory's value function specifically. Further, we investigate the form of this function across nine countries that range in power distance. Results suggest that the form of the value function is congruent with prospect theory, showing an S‐shaped curve that is steeper in the loss than in the gain domain. Further, this pattern is similar across countries. Theoretical and practical implications of these results for both decision making and organizational justice are discussed.

Categorical perception of colour in the left and right visual field is verbally mediated: evidence from Korean

In this study we demonstrate that Korean (but not English) speakers show Categorical perception (CP) on a visual search task for a boundary between two Korean colour categories that is not marked in English. These effects were observed regardless of whether target items were presented to the left or right visual field. Because this boundary is unique to Korean, these results are not consistent with a suggestion made by Drivonikou [Drivonikou, G. V., Kay, P., Regier, T., Ivry, R. B., Gilbert, A. L., Franklin, A. et al. (2007) Further evidence that Whorfian effects are stronger in the right visual field than in the left. Proceedings of the National Academy of Sciences 104, 1097-1102] that CP effects in the left visual field provide evidence for the existence of a set of universal colour categories. Dividing Korean participants into fast and slow responders demonstrated that fast responders show CP only in the right visual field while slow responders show CP in both visual fields. We argue that this finding is consistent with the view that CP in both visual fields is verbally mediated by the left hemisphere language system.     

On loss aversion in capuchin monkeys

Chen, Lakshminarayanan, and Santos (2006) claim to show in three choice experiments that monkeys react rationally to price and wealth shocks, but, when faced with gambles, display hallmark, human-like biases that include loss aversion. We present three experiments with monkeys and humans consistent with a reinterpretation of their data that attributes their results not to loss aversion, but to differences between choice alternatives in delay of reinforcement.
