“易得性启发式”与决策框架对风险决策倾向的影响

研究目的:探讨易得性启发式对风险决策认知过程的影响,以及易得性启发式与决策框架相互作用下的风险投资行为特点。方法:采用2×2×7混合实验设计和情境实验。结果:成功结果的易得性启发式导致对风险决策问题采用自上而下加工,失败结果为自下而上加工;成功结果时投资倾向为风险趋向,失败结果为风险规避;易得性启发式与决策框架共同影响风险投资倾向。结论:易得性启发式影响风险决策的认知加工过程,并与决策框架对风险投资倾向产生交互作用。     

Transit Space: No Place is Nowhere

This article deals with representations of one specific city, Århus, Denmark, especially its central district. The analysis is based on anthropological fieldwork conducted in Skåde Bakker and Fedet, two well-off neighborhoods. The overall purpose of the project is to study perceptions of space and the interaction of cultural, social, and spatial organizations, as seen from the point of view of people living in Skåde Bakker and Fedet. The focus is on the city dwellers’ representations of the central district of Århus with specific reference to the concept of transit space. When applied to various Århusian locations, this might highlight unforeseen meanings and paradoxes.     

虚拟空间语言学研究现状和展望

The allure of equality: uniformity in probabilistic and statistical judgment

Uniformity, that is, equiprobability of all available options is central as a theoretical presupposition and as a computational tool in probability theory. It is justified only when applied to an appropriate sample space. In five studies, we posed diversified problems that called for unequal probabilities or weights to be assigned to the given units. The predominant response was choice of equal probabilities and weights. Many participants failed the task of partitioning the possibilities into elements that justify uniformity. The uniformity fallacy proved compelling and robust across varied content areas, tasks, and cases in which the correct weights should either have been directly or inversely proportional to their respective values. Debiasing measures included presenting individualized and visual data and asking for extreme comparisons. The preference of uniformity obtains across several contexts. It seems to serve as an anchor also in mathematical and social judgments. People’s pervasive partiality for uniformity is explained as a quest for fairness and symmetry, and possibly in terms of expediency.     

Distributed skill functions and the meshing of knowledge structures

The scope of knowledge space theory was extended by bringing into the picture the underlying skills and capabilities that are relevant to solving the problems in a knowledge domain. A major challenge to this approach comes from the need to aggregate distributed information on (partially) overlapping domains and skill sets. The notion of a distributed skill function is introduced for formalizing the integration of several skill functions that represent the assignment of skills to problems. It is shown that their consistency is captured by the meshability of the delineated knowledge structures. This result draws upon a characterization of the meshing of finite or infinite collections of knowledge structures, which extends and generalizes previous results on the binary case. The discussion covers implications for knowledge assessment and for practical applications, such as integrating skill assignments coming from different experts or distributed resources in technology-enhanced learning.     

贝叶斯网在认知诊断属性层级结构确定中的应用

K. K. Tatsuoka和她同事研究的规则空间模型(RSM)是一种在国内外有较大影响的认知诊断模型, 但是Tatsuoka的RSM是由学科专家先从已编制的测验中抽取出属性, 然后给出测验的关联Q阵, 再由该Q阵导出属性间的层级关系。已有研究证明, 这种做法所得到的属性间的层级关系难以保证是正确的, 甚至难以保证属性间的层级关系是唯一确定的。这里利用贝叶斯网进行结构学习, 从被试的属性掌握模式中挖掘出属性间的层级关系, 学习所得到的层级关系可以用来验证由RSM中的方法得到的层级关系。模拟实验和实证研究的结果都显示了该方法所得到的属性层级关系是有参考价值的, 可以为命题或测量专家带来有用的信息。     

The observing ego as voyeur

A resistance to self-observation and self-reflection is discussed in which there is a perversion of the observing ego. The observing ego has been unconsciously recruited in the service of enacting an unconscious fantasy: the fantasy of being an excited observer of a primal scene who is punished for making forbidden observations. This voyeuristic observing ego is pathologically enmeshed in a love triangle with the patient's seductive superego (i.e. identification with the desired but unfaithful parent) and with the patient's punitive superego (i.e. identification with the rivalrous parent). This unconscious scenario is played out in the clinical situation as the patient unreflectively cycles through phases of denial (i.e. self-seduction) and moral masochism (i.e. self-betrayal). A case study illustrates how humor may be employed to free the observing ego from being enthralled by a perverse superego. Humor may unconsciously enable a rebellious attitude toward the omnipotent sadism of a perversely oppressive superego and thus enable the observing ego to break free from its pathological enmeshment.     

The impulse to infidelity and oedipal splitting

Freud suggested that the child perceives parental intercourse as an act of infi delity by the desired but unfaithful parent. Parental sexual infi delity is felt to be a major narcissistic injury that gives rise to fantasies of revenge. A defensive organization arises to manage this trauma and its attendant revenge fantasies. That organization involves splitting of the desired parent into faithful and unfaithful parts, displacement of hostility on to the rival parent, and identifi cation with the desired but unfaithful parent resulting in the impulse to infi delity. Romantic fantasies of escape and rescue from evil rivals provide guilt free ways of satisfying fantasies of oedipal revenge. In those fantasies the evil rival is turned into an injured third party who gets his or her just deserts as the romantic couple gets to live happily ever after. This defensive organization may embroil patients in complicated love triangles as adults for which they may seek treatment. Analyzing the repudiated narcissistic wound of parental infi delity and the disguised revenge fantasies that defend against that wound may provoke narcissistic rage towards the analyst as a moralistic, possessive, controlling, envious, and spoiling oedipal parent.     

Beyond illusion: Psychoanalysis and the question of religious truth1

In this paper the author critically examines the nature of the positive, reconciliatory attitude towards religion that has become increasingly prevalent within psychoanalytic thinking and writing over the past 20 years. She shows how this positive attitude rests on a change in the nature of the prototype of religion and its reassignment to the realm of illusion, thus making irrelevant an issue most central both to psychoanalysis and to traditional Judeo‐Christian belief ‐ the passionate search for truth. The author demonstrates how the concern with truth, and specifically with the truth of religious claims, lies at the basis of the opposition between psychoanalysis and religion but, paradoxically, also provides the common ground for dialogue between the two. She argues that, as Freud developed his ideas regarding the origin of conviction in religious claims in his Moses and monotheism (1939), the nature of this common ground was expanded and the dialogue became potentially more meaningful. The author concludes that meaningful dialogue emerges through recognition of fundamental differences rather than through harmonisation within a realm of illusion. In this light, the present study may also be seen as an attempt to recognise fundamental differences that have been evolving within psychoanalysis itself.
