Evaluating Explanations in Law, Science, and Everyday Life 总被引:1,自引:0,他引:1
Paul Thagard 《Current directions in psychological science》2006,15(3):141-145
ABSTRACT— This article reviews a theory of explanatory coherence that provides a psychologically plausible account of how people evaluate competing explanations. The theory is implemented in a computational model that uses simple artificial neural networks to simulate many important cases of scientific and legal reasoning. Current research directions include extensions to emotional thinking and implementation in more biologically realistic neural networks. 相似文献

Karmiloff-Smith提出的表征重述理论认为表征重述是人类获取知识的重要途径。为探讨练习是否能够提供表征重述的机会从而促进表征水平的变化,对29名小学一年级儿童进行数字分解组合任务的研究。结果表明:(1)练习背景下约有半数儿童的表征从内隐水平发展到外显水平,但其他儿童的表征水平没有发生任何变化;(2)练习背景下儿童表征变化的路线并不完全像Karmiloff-Smith设想的那样经由程序阶段到元程序阶段再到概念化阶段,而是存在其他多种可能的发展路线;(3)练习背景下儿童获得的表征的灵活性是有限的,即可以推广到近迁移问题上,而难以推广到远迁移问题上 相似文献

Computation and philosophy intersect three times in this essay. Computation is considered as an object, as a method, and as a model used in a certain line of philosophical inquiry concerning the relation of mind to matter. As object, the question considered is whether computation and related notions of mental representation constitute the best ways to conceive of how physical systems give rise to mental properties. As method and model, the computational techniques of artificial life and embodied evolutionary connectionism are used to conduct prosthetically enhanced thought experiments concerning the evolvability of mental representations. Central to this essay is a discussion of the computer simulation and evolution of three-dimensional synthetic animals with neural network controllers. The minimally cognitive behavior of finding food by exhibiting positive chemotaxis is simulated with swimming and walking creatures. These simulations form the basis of a discussion of the evolutionary and neurocomputational bases of the incremental emergence of more complex forms of cognition. Other related work has been used to attack computational and representational theories of cognition. In contrast, I argue that the proper understanding of the evolutionary emergence of minimally cognitive behaviors is computational and representational through and through. 相似文献

The distinction between implicit (non-conscious) and explicit (conscious) knowledge made by cognitive scientists is applied to the psychoanalytic idea of repressed contents. The consequences of repression are suggested to have been caused by implicit representations. Repressed memories can also be treated in terms of explicit representations, which are prevented from becoming activated. Implicit knowledge cannot, however, be made conscious, and thus the idea of becoming conscious of the repressed desires and fears that have never been conscious is contradictory. This tension may be relieved by reconceptualising the idea of becoming conscious of the repressed. It is suggested that this could be seen as creating explicit knowledge about the effects of implicit representations. By applying the implicit/explicit knowledge distinction, psychoanalytic ideas concerning the repressed could be connected to current views in the domain of cognitive orientation. 相似文献

内隐时间表征的实验研究 总被引:5,自引:1,他引:4
用两个实验五种作业,探讨内隐时间表征存在的可能性及其特点。结果表明:在表征动量中,(1)无论诱导图形内隐运动方向向左还是向右,测试图形与识记图形之间位置偏移的错误率在与诱导图形内隐运动方向一致的条件下比不一致的条件下大;(2)诱导图形内隐运动的一致性时间顺序消失之后,表征动量不存在;(3)在100ms的时间范围内,识记图形、测试图形之间的保持时距与记忆位置偏移呈线性相关;(4)在水平方向和垂直方向上,客体的概念和背景知识对表征动量无影响,研究结果肯定了表征动量中内隐时间表征的存在并具有方向性、顺序性、连续性和认知不可渗透性的特点。 相似文献

In this paper I propose a cognitive interpretation of the emergence of monotheism. I first distinguish between two fundamentally different conceptions of representation: one intuitive, which favors an analog model of rational cognition, and one discursive, which favors a digital model. While both Hellenism and Judaism may have been instrumental in setting civilization on the path to reason and law, it is the discursive or digital conception of God as a single universal Judge, I argue, that provides the foundational axiom of the moral logic of the Hebrew Scriptures. That is, in monotheism, God came to be represented differently. 相似文献
