Quine's Argument from Despair

Quine's argument for a naturalized epistemology is routinely perceived as an argument from despair: traditional epistemology must be abandoned because all attempts to deduce our scientific theories from sense experience have failed. In this paper, I will show that this picture is historically inaccurate and that Quine's argument against first philosophy is considerably stronger and subtler than the standard conception suggests. For Quine, the first philosopher's quest for foundations is inherently incoherent; the very idea of a self-sufficient sense datum language is a mistake, there is no science-independent perspective from which to validate science. I will argue that a great deal of the confusion surrounding Quine's argument is prompted by certain phrases in his seminal ‘Epistemology Naturalized’. Scrutinizing Quine's work both before and after the latter paper provides a better key to understanding his remarkable views about the epistemological relation between theory and evidence.     

Segmentation of object outlines into parts: a large-scale integrative study

In this study, a large number of observers (N=201) were asked to segment a collection of outlines derived from line drawings of everyday objects (N=88). This data set was then used as a benchmark to evaluate current models of object segmentation. All of the previously proposed rules of segmentation were found supported in our results. For example, minima of curvature (i.e. locations along the contour where negative curvature takes an extreme value) were often used as segmentation points. The second point of a pair connected by a segmentation line often depended on more global shape characteristics such as proximity, collinearity, symmetry, and elongation. Based on these results, a framework is presented in which all of the previously proposed (and now empirically validated) segmentation rules or rules for part formation are integrated.     

Problem behavior maintained by a precurrent relation

Differential reinforcement of alternative behavior is a well-established treatment for problem behavior in which the functional reinforcer is delivered after the occurrence of a replacement behavior and withheld after the occurrence of problem behavior. However, sometimes problem behavior continues to occur under these conditions, raising a question as to why problem behavior might maintain when its reinforcer is withheld. This study examined the possibility that problem behavior could be maintained indirectly in a precurrent relation. A functional analysis was conducted to identify a response-response relation between self-injurious behavior (SIB) and an alternative response. The results suggest that SIB was maintained by its relation with the alternative response.     

Theoretische Lücken der Cognitive Science

Theoretical gaps of the cognitive science. First of all the gap-thesis is based on a criticism 1. of the computer-orientated cognitive science (it confuses information with the information carrier), 2. of connectivism (its linguistic borrowing from the neurobiology is not appropriate), 3. of Varelas production model (the elimination of the function of representation results in the loss of the cognitive ability). From the context of meaning and time, then the author sketches a cognitive theoretical approach, in which thinking as a (symbolic and/or subsymbolic) representation of meaning is introduced, which develops in a three-digit relation between world, language and substrate on the basis of isomorphy of time.

妇产科教学如何应对新的医疗环境

近年来，患者维权意识增强，医患关系紧张，妇产科教学面临着缺乏实践教学对象，教学任务不能落实的尴尬局面。只有在教学中渗透医德教育，提高医疗风险意识，加强教师素质培训，尽力协调好医患关系，应用先进科学的教学方法，才能保证教学质量，从而使妇产科教学落到实处。     

基于线索的视觉空间关系判断

融合视觉空间关系识别中的类别关系判断和数量（坐标）关系判断,通过4个实验探讨了影响视觉空间关系判断的线索性方面的因素。结果表明：视觉空间关系判断受角度影响不明显;单线索条件下刺激越靠近可视线索,判断绩效越好;多线索条件下在不显著延长反应时间的情况下有助于提高视觉空间关系判断的正确率;另外不均匀条件（边界线有一定斜率）不利于视觉空间关系的判断。     

颜色词与颜色认知的关系

颜色词作为一个特殊词类,是探讨语言与认知关系的重要途径。文章综述了颜色知觉和颜色词分类等领域的研究,重点介绍了有关颜色词与认知的两种理论：颜色词的普遍进化理论和语言关联性假设,前者认为颜色词与颜色认知是相对独立的,后者认为语言与认知相互影响。文章综述了与这两种理论有关的一些最新研究进展,并对该领域研究提出一些新的研究思路,如研究颜色词的联想意义、颜色词与民族心理、复合颜色词的加工及对认知的影响、通感现象、颜色词的概念组织等。     

态度结构一致性及其对态度和行为的影响

态度结构一致性指态度的情感或认知成分与总体态度的一致程度以及态度的情感与认知成分两者间的一致程度。本文介绍了结构一致性的界定和操作方法,回顾了结构一致性对态度和行为的影响,包括其在态度形成中的作用以及对态度可获得性和态度-行为关系的影响。同时指出未来研究应关注各种结构一致性的交互,将结构一致性研究推广到群体水平,并进一步应用于社会预警研究。     

Rapid word learning in 13- and 17-month-olds in a naturalistic two-word procedure: looking versus reaching measures

This study investigated infants’ rapid learning of two novel words using a preferential looking measure compared with a preferential reaching measure. In Experiment 1, 21 13-month-olds and 20 17-month-olds were given 12 novel label exposures (6 per trial) for each of two novel objects. Next, in the label comprehension tests, infants were shown both objects and were asked, “Where’s the [label]?” (looking preference) and then told, “Put the [label] in the basket” (reaching preference). Only the 13-month-olds showed rapid word learning on the looking measure; neither age group showed rapid word learning on the reaching measure. In Experiment 2, the procedure was repeated 24 h later with 10 participants per age group from Experiment 1. After a further 12 labels per object, both age groups now showed robust evidence of rapid word learning, but again only on the looking measure. This is the earliest looking-based evidence of rapid word learning in infants in a well-controlled (i.e., two-word) procedure; our failure to replicate previous reports of rapid word learning in 13-month-olds with a preferential reaching measure may be due to our use of more rigorous controls for object preferences. The superior performance of the younger infants on the looking measure in Experiment 1 was not straightforwardly predicted by existing theoretical accounts of word learning.     

Sign,Image and Language in The Book of Changes CYijing 易经）

It is challenging to estimate the degree to which the system of the Trigrams and Hexagrams in The Book of Changes （Yijing） had an impact on the whole history of Chinese thought. The universal paradigm from which it was derived formed the basis of a semiotic theory of evolution which, because of structural analogies, was applied to all fields and aspects of human life where decision making and action in correspondence with a cosmic principle was required. To achieve that goal, countless commentaries on and interpretations of the Yijing have been written. They can be divided into two schools. The first used the Yijing as a book for divination, in combination with manifestations of the universe and nature. The second interpreted it with a philosophical background, making it part of the tradition of Confucian thought. Modem scholars have also contributed some new approaches to the Yijing. My paper is based on the assumption that the Trigrams and Hexagrams of the Yijing cannot be understood in a purely representational way. They do not represent things apart from their relation to human needs or consciousness. Because of the co-determination of text and reader as a task without determinate end-points, it proves to be a unique case of effective-history. In the Yijing, there is no real line between culture and nature, sign/image/language and fact, the universe of semiosis and other universes. With its use of signs, images and language, the Yijing confirms that the universe of semiosis is the universe of heaven, earth and man. Against this background, my explanations will not only focus on the Trigrams and Hexagrams. My paper will also deal with the following topics： （1） interpenetration of linguistic meaning and objective reality and （2） the social nature of verbal or literary expression.
