Dealing with Big Numbers: Representation and Understanding of Magnitudes Outside of Human Experience

Being able to estimate quantity is important in everyday life and for success in the STEM disciplines. However, people have difficulty reasoning about magnitudes outside of human perception (e.g., nanoseconds, geologic time). This study examines patterns of estimation errors across temporal and spatial magnitudes at large scales. We evaluated the effectiveness of hierarchical alignment in improving estimations, and transfer across dimensions. The activity was successful in increasing accuracy for temporal and spatial magnitudes, and learning transferred to the estimation of numeric magnitudes associated with events and objects. However, there were also a number of informative differences in performance on temporal, spatial, and numeric magnitude measures, suggesting that participants possess different categorical information for these scales. Educational implications are discussed.     

盲人建构陌生环境空间表征的策略及其作用

空间表征对于盲人定向行走具有重要意义。以往研究者集中探讨早期视觉经验缺失对于盲人空间表征的影响, 较少探究空间表征建构的过程性因素, 即探路策略对于盲人空间表征的影响。本研究采用现场实验的方法探究了盲人建构陌生环境空间表征采用的策略及其作用。结果发现：视觉经验缺失对盲人陌生环境空间表征能力造成了不利影响, 然而, 被试运用有效的策略可以弥补视觉缺失带来的损失, 且利用空间关系策略的个体所建构的空间表征更为精确, 定向行走效率也更高。     

情绪概念加工与情绪面孔知觉的相互影响

通过3个实验探讨情绪概念加工与情绪面孔知觉是否存在相互影响, 以及加工深度对两者关系的影响。实验1采用情绪面孔启动范式, 探讨较深的情绪概念加工层面对情绪概念与情绪面孔的关系的影响。实验2更改概念任务, 探讨较浅的概念加工层面对两者关系的影响。实验3缩短启动面孔呈现时间, 探讨较浅的面孔知觉层面对两者关系的影响。通过研究主要得出以下结论：(1)情绪概念加工与情绪面孔知觉确实存在相互影响; (2)概念加工深度影响两者关系的方向性, 在较深的概念加工层面, 两者的关系是双向的, 在较浅的概念加工层面, 两者的关系是单向的; (3)知觉加工深度也影响两者关系的方向性, 在较深的知觉加工层面, 两者的关系是双向的, 在较浅的知觉加工层面, 没有发现两者的相互影响。本研究为抽象概念的具身表征提供了实证支持。     

中文词汇加工中的饱和现象

长时间注视一个字或词语后,感觉这个字词变得奇怪且陌生,这种现象称为饱和现象。本研究采用快速类别/词汇匹配范式,考察中文词汇加工中的饱和现象。实验1-3发现单纯的语义或字形的重复均未能引发饱和,只有类别标签在字形和语义上的同时重复才引发饱和,表明与英文饱和相似,中文饱和发生在字形加工和语义加工的联结阶段。实验4结果表明,中文饱和还能够由表义部件的重复引发,体现了中文饱和的特殊性。     

Psychoanalytic application and psychoanalytic integrity

In this article, the author offers an analysis of psychoanalytic application, defined as the breaking of new conceptual ground in some field of knowledge whereby the new idea is conceived, and later articulated, with the aid of reference to analogous phenomena in psychoanalysis. It requires apt analogy based on competent understanding of the applied field and of psychoanalysis. Only when the relevant differences between the applied and psychoanalytic fields are grasped can the extent of certain parallels emerge. The thinking by analogy that comprises psychoanalytic application may be intuitive and implicit, but should be susceptible of explicit theoretical elaboration that specifies, precisely, the point(s) of correspondence between psychoanalysis and the applied field in relation to a precise specification of their relevant differences. Applied psychotherapy at the interface of the internal and external worlds (historically rooted in casework) is employed as a model. By analogy with Donnet's concept of the analytic site, the author proposes the concept of the psychodynamic (case)work site, and elaborates it for that applied field in order to elucidate the proposed principles of psychoanalytic application.     

The basic traumatic situation in the analytical relationship1

The author attempts to develop a concept of psychic trauma which would comply with the nucleus of this Freudian notion, that is, an excess of excitations that cannot be processed by the mental apparatus, but which would also consider the functions and the crucial role of objects in the constitution of the psychism and in traumatic conditions, as well as taking into account the methodological positioning according to which the analytical relationship is the sole possible locus of observation, inference and intervention by the psychoanalyst. He considers as a basic or minimal traumatic psychoanalytical situation that in which a magnitude or quality of emotions exceeds the capacity for containment of the psychoanalytical pair, to the point of generating a period or area of dementalisation in the psyche of one or both of the participants, of requiring analytical work on the matter and promoting a signifi cant positive or negative change in the relationship. Availing himself of Bion's theory about the alpha function and the metapsychological conceptions of Freud and Green concerning psychic representations, he presents two theoretical formulations relating to this traumatic situation, utilising them according to the ‘altered focus’ model proposed by Bion. He presents three clinical examples to illustrate the concept and the relevant theoretical formulations.     

A generalization of Piéron's law to include background intensity and latency distribution

Piéron's law, which formulates the effect of the signal intensity i on the mean or the median reaction time (MRT) as a power function, MRT=R+i^-βC, in which R, β and C are positive parameters, is of much interest in the simple reaction time literature. In particular, consistent estimates of β are obtained. However, this law offers no information regarding the effect of the signal intensity on other aspects of the reaction time distribution. In addition, the background intensity, which also has some impact on the detectability of the signal, is not considered in Piéron's law. In this paper, we generalize Piéron's law based on the above comments. That is, we assume that both β and C are functions of the background intensity and of the percentile rank. We then investigate from a theoretical viewpoint some possible functional forms of β and C, with a special emphasis on the dependency of β on the background intensity. It is shown that the so-called “Fechner-Thurstone-type representation” forces β and C to be “separable.” If we further assume a near-miss to Weber's law-type representation, then the functional form of β can be determined.     

中-英双语语义通达机制的启动效应实验

采用不同加工水平的词汇判断任务,考察了启动刺激对目标刺激的启动效应,来探讨中英双语的语义通达机制。被试为大学生38名。结果发现：当启动刺激（英）和目标刺激（英）之间存在语义联想关系,得到了显著的启动效应（实验一）;当启动刺激（中）和目标刺激（英）之间存在语义联想关系,也得到了显著的跨语言启动效应（实验二）;当启动刺激（中）的翻译对等词和目标刺激（英）之间存在语音相同或相近关系时,采用基于语音的词汇判断任务,也得到了显著的跨语言启动效应。这一结果表明,对于中英双语者来说,第二语言的词汇表征既直接通达语义概念表征,又可以借助第一语言的词汇表征为中介再通达语义概念表征。     

Rule-based schema matching for ontology-based mediators

Mediating heterogeneous data sources heavily relies on explicit domain knowledge expressed, for example, as ontologies and mapping rules. We discuss the use of logic representations for mapping schema elements onto concepts expressed in a simplified ontology for cultural assets. Starting with a logic representation of the ontology, criteria for a rule-based schema matching are exemplified. Special requirements are the handling of uncertain information and the processing of hierarchical XML structures representing instances.     

不熟练汉英双语学习者第二语言词汇和概念表征的特点

本研究采用翻译识别任务探查了不同熟练程度的汉英双语儿童的词汇和概念表征的特点。被试为从一年级开始学习英语的小学三、五年级和初中一年级儿童共50名,结果发现．各组被试在进行翻译识别时．反应错误率随着熟练程度的提高逐渐降低,且各组被试都产生了显著的正字法干扰效应和语义干扰效应。这一结果表明,不熟练的汉英双语儿童可以通过词汇联系和概念联系加工第二语言中的词。
