Questions épistémologiques et méthodologiques sur la validation en psychanalyse

The question of the psychoanalysis as science is recurring. We can consider, at the very least, that it is a practice based on a rational and formal theory. But, according to the project of Freud to give it statute of an empirical science, remains to find the method which would allow, in a field which lends itself badly to the traditional experimentation or even “with single case”, to validate its proposals empirically. Here the difficulties and condition of such a validation are examined, which would allow, moreover, of advancing on the question of the evaluation of its therapeutic effects.     

Reference dependence in iterative choices

Valuation of goods often proceeds from a series of hypothetical pairwise choices. We examine reference dependence on the outcome of such evaluations in a large-scale study in which respondents make a series of choices between areas that differ on cost of living and the quality of lakes and rivers. We uncover three substantial reference effects. First, we find that respondents’ choices are altered by being told the national value of water quality. For these people, consistent with prospect theory, changes in water quality below the 65% referenced national standard are treated as losses and given more weight while identical changes above 65% are treated as gains and given less weight. Second, we find that the sequence of iterative choices matters in a surprising way. The iterations proceed by encouraging switching either by degrading the chosen alternative or improving the item chosen. We show that improving the item not chosen produces the greatest switching, a result consistent with prospect theory, but only if the item changed in the iteration becomes the reference alternative. Finally, we find a strong starting reference effect. That is, we show that the trade-off in the first choice reflected in the change in cost of living divided by the change in water quality has a substantial impact on the final valuation. We assess the relative impact of these three reference effects and suggest ways of dealing with them for valuation of non-market goods.     

Subjective valuation and asymmetrical motivational systems: implications of scope insensitivity for decision making

Studies using the Iowa Gambling Task have revealed individual differences in performance on the task. In this study, we tested the hypothesis that approach and avoidance motivations influence decision making through the process of subjective valuation. We examined the implications of a high sensitivity to gains or losses from two perspectives which we labeled scalar multiplication and valuation by feeling. Using two versions of the Iowa Gambling Task, we find evidence supporting the view that asymmetry in the systems regulating approach and avoidance leads to systematic biases that translate to differences in performance. Specifically, we find that high sensitivity in the Behavioral Activation System (BAS) translates to valuation by feeling and insensitivity to scope in the domain of gains, while high sensitivity in the Behavioral Inhibition System (BIS) translates to valuation by feeling and insensitivity to scope in the domain of losses. The basis for these findings is discussed. Copyright © 2007 John Wiley & Sons, Ltd.     

Beyond Positivist Ecology: Toward an Integrated Ecological Ethics

A post-positivist understanding of ecological science and the call for an “ecological ethic” indicate the need for a radically new approach to evaluating environmental change. The positivist view of science cannot capture the essence of environmental sciences because the recent work of “reflexive” ecological modelers shows that this requires a reconceptualization of the way in which values and ecological models interact in scientific process. Reflexive modelers are ecological modelers who believe it is appropriate for ecologists to examine the motives for their choices in developing models; this self-reflexive approach opens the door to a new way of integrating values into public discourse and to a more comprehensive approach to evaluating ecological change. This reflexive building of ecological models is introduced through the transformative simile of Aldo Leopold, which shows that learning to “think like a mountain” involves a shift in both ecological modeling and in values and responsibility. An adequate, interdisciplinary approach to ecological valuation, requires a re-framing of the evaluation questions in entirely new ways, i.e., a review of the current status of interdisciplinary value theory with respect to ecological values reveals that neither of the widely accepted theories of environmental value—neither economic utilitarianism nor intrinsic value theory (environmental ethics)—provides a foundation for an ecologically sensitive evaluation process. Thus, a new, ecologically sensitive, and more comprehensive approach to evaluating ecological change would include an examination of the metaphors that motivate the models used to describe environmental change.

不作为惯性产生的原因、条件及应用

不作为惯性指如果个体先前已错过了一个更优的机会, 当次一些的类似机会再出现时(但仍好于一般情况), 个体会倾向于继续放弃这一机会。本文首先简要介绍了不作为惯性的概念、操作定义和基本研究方法; 然后着重探讨了导致不作为惯性的原因及相关实证研究, 目前研究者普遍认为后悔情绪和估价是导致不作为惯性的两个主要原因; 随后探讨了不作为惯性产生的条件及在市场营销及股票市场中的应用研究; 最后未来研究需要更加注重研究方法上的改进以及对不作为惰性的原因探讨。     

转移方式对基于劳动的物品所有权判断的影响

劳动在人们的所有权判断中起着重要作用。以往研究虽然考察了幼儿和成人基于劳动的所有权判断,但却忽视了原材料转移方式的作用,且大部分集中在西方国家。本研究以中国3～5岁的幼儿和成人为对象,考察了他们在拿和借两种转移方式下基于劳动的所有权判断。结果发现,4～5岁的幼儿及成人在两种转移方式下的所有权判断存在显著差异。相比于拿条件,他们在借条件下不太倾向于判断劳动者是新加工物品的所有者。4～5岁幼儿在拿条件下更倾向认为劳动者是新加工物品的所有者,而成人在两种条件下都倾向于支持原材料占有者是新加工物品的所有者。3岁幼儿在两种转移方式下的所有权判断不存在显著差异,且不支持任何一方。结果提示,转移方式会影响个体基于劳动的所有权判断,并且从4岁开始幼儿能够区分不同转移方式的作用。     

临床病理诊断中蕴涵的哲学原理及其重要性初探

准确的临床病理诊断有赖于正确的思维方法,将哲学原理运用于临床病理诊断有利于更准确地诊断疾病。在临床病理诊断中应注重和运用理论源于实践,又反过来指导实践;透过现象看本质,抓住事物的主要矛盾;事物的发展具有普遍规律和特殊规律两个方面;事物是普遍联系的等原理。     

患者的自主权及困境

在生命伦理学中,尊重自主性原则是指尊重病人或受试者的自主性,可理解为病人自主原则。自主性的实现涉及到自主性的人与自主性的选择,面对复杂的医疗情境,患者自主权的实施面临着重重困境。从自主、病人自主原则、病人自主的实践三个层面讨论了该原则,并尝试用境遇伦理学原理来解决病人自主原则的实践困境。     

CHARLES LYELL,UNIFORMITARIANISM, AND INTERPRETIVE PRINCIPLES

I examine the development of Charles Lyell's principle of uniformity and its influence on the development of modern geology and biology and argue that distinguishing between philosophical starting points and empirical findings is essential for clarity in the discussion between science and religion. First, I explore Lyell's arguments against catastrophism and how these were both empirically and religiously motivated. I then consider how David Hume's empiricism, theory of causation, and rejection of miracles influenced Lyell. Using these insights, Lyell formulated his principle of uniformity, which he believed was based on current empirical findings, and rejected explanatory hypotheses that used the biblical Flood or other catastrophist accounts as violations of uniform causation and introductions of theological concepts into empirical science. I next examine the influence of Lyell's principle on Charles Darwin. Although Lyell opposed Darwinism for most of his life, Darwin relied heavily on Lyell, as is evidenced by references throughout The Origin of Species. I contend that the most important aspect of Lyell's principle for Darwin is that it makes natural evil (the struggle for survival) a process that has always been occurring rather than something introduced after the Fall as recorded in Genesis. Finally, I discuss the role that uniformity plays for Lyell, Darwin, and modern science as an interpretive principle rather than as an inference from empirical data, and I conclude by noting that keeping the distinction in mind between interpretive principles and empirical findings will help clarify debates between science and religion.     

Contribution of the visual perception and graphic production systems to the copying of complex geometrical drawings: A developmental study

The aim of this study was to determine the contribution of the visual perception and graphic production systems [Van Sommers, P. (1989). A system for drawing and drawing-related neuropsychology. Cognitive Neuropsychology, 6, 117–164] to the manifestation of the “Centripetal Execution Principle” (CEP), a graphic rule for the copying of drawings consisting of embedded simple geometric shapes from the outside shape to the inside shape. Children aged 4–8 years copied two types of model that differed in the visual salience of one of the simple geometric shapes (drawn in bold or normal weight lines), producing the drawings either by graphic execution (freehand) or by superimposing the simple geometric shapes. The results indicated that the frequency of CEP depended both on the type of model and on the drawing context in the youngest children. They suggest that the CEP is determined by the structure of the representation of the models and the planning of the execution of the drawings. The developmental differences in the effects of visual salience and execution context are discussed in the light of the development of representational flexibility and planning abilities. These data are consistent with a dissociation between the visual perception and graphic production systems and account for their interaction.
