Nearly all of the ways philosophers currently attempt to define the terms ‘representation’ and ‘function’ undermine the scientific
application of those terms by rendering the scientific explanations in which they occur vacuous. Since this is unacceptable,
we must develop analyses of these terms that avoid this vacuity.
Robert Cummins argues in this fashion in Representations, Targets, and Attitudes. He accuses ‘use theories’ of representational content of generating vacuous explanations, claims that nearly all current
theories of representational content are use theories, and offers a non-use theory of representational content which avoids
explanatory vacuity. One task I undertake in this article is to develop an alternative non-use theory which avoids an objection
fatal to that theory.
My second task is to adapt Cummins’ argument to criticize most current analyses of ‘function,’ which undermine scientific
explanation in an analogous way. Though Cummins does not explicitly argue in this manner, his own analysis of ‘function,’
by avoiding any appeal to use, avoids the explanatory vacuity to which they succumb. Consequently, I endorse Cummins’ notion
of function.
However, although use theories fail as analyses of the terms ‘representation’ and ‘function,’ they can still make significant
contributions to the sciences employing these terms. For, while philosophers seeking to define ‘representation’ and ‘function’
must avoid incorporating representational and functional uses into their definitions, scientists must still find a way to
determine which representations and functions are being used. Suitably re-construed use theories of representation and function
may in many cases assist them in this task. 相似文献

Similarity is central in human cognition, playing a role in a wide range of cognitive processes. In three studies, we demonstrate that subjective similarity may change as a function of temporal distance, with some events seeming more similar when considered in the near future, while others increase in similarity as temporal distance increases. Given the ubiquity of inter-temporal thought, and the fundamental role of similarity, these results have important implications for cognition in general. 相似文献

意见收敛定理是主观主义概率论的一条重要定理,它表明随着证据的增加,验前概率的主观性将被验后概率的客观性所代替。意见收敛定理被看作主观概率的动态合理性原则,因而被用来解决休谟问题,即归纳合理性问题。然而,哈金有说服力地表明,意见收敛定理证明的是条件概率Pr(h/e)的收敛,而不是验后概率Pre(h)的收敛。主观主义概率论暗中接受的一个等式是:Pre(h)=Pr(h/e),通常称之为“条件化规则”。这样,归纳法的合理性问题变成条件化规则的合理性问题。为此,本文提出一个新的合理性原则,即“最少初始概率原则”,将它同“局部合理性”观念结合起来便可为条件化规则的合理性加以辩护。 相似文献

We investigated the development of code specific representations of different kinds of information in long term memory. Forty
second graders, 40 sixth graders and 40 adults learned the associations between 12 pictures and one position each in a 4 × 3
grid of squares, 12 pictures and 1 of 12 monosyllabic words each or 12 pictures and 1 of 12 faces. After a 3 min distractor
task, a picture was presented in the retrieval phase, and the associated position, word or face had to be selected. Performance
in the verbal condition improved as a function of age, while performance in the spatial condition turned out to be independent
of age, and the performance in the facial condition showed a difference between both child groups and the adults. The results
revealed a developmental difference of code specific representation of different kinds of information. 相似文献

Telework, namely so remote work, is composed of three basic forms: home based-telework, alternated telework and mobile telework. These three basic forms of telework and the traditional form of work are compared to identify their respective impact on work centrality, work social representation, and on relations between work life and out of work life. The mobile teleworkers present a high work centrality and the alternated teleworkers, a high family centrality. Concerning the representation, only mobile teleworkers and home based teleworkers cannot think the work without the basic knowledge of constraint. For the exchanges between work of life and out of work life, traditional workers separate their domains of life even though alternated teleworkers and home based-teleworkers combinate it. Mobile teleworkers develop exchanges between some domains of life.This study proves that it is not necessary to reason globally but to consider the specificity of each telework forms introduced or to implant in a organization. 相似文献

Hilbert's ε-calculus is based on an extension of the language of predicate logic by a term-forming operator e x . Two fundamental results about the ε-calculus, the first and second epsilon theorem, play a rôle similar to that which the cut-elimination theorem plays in sequent calculus. In particular, Herbrand's Theorem is a consequence of the epsilon theorems. The paper investigates the epsilon theorems and the complexity of the elimination procedure underlying their proof, as well as the length of Herbrand disjunctions of existential theorems obtained by this elimination procedure. 相似文献

采用句子-图形验证任务初步探讨了不同汉语水平的印尼留学生理解汉语主动句、被动句所形成的命题表征中的项目顺序特点。结果表明,初级汉语水平印尼留学生理解汉语主动句、被动句后所建构的命题表征中项目顺序均为“受事→施事”;中级汉语水平印尼留学生理解汉语主动句所形成的命题表征项目顺序为“施事→受事”,而其理解汉语被动句所形成的命题表征项目顺序为“受事→施事”。母语主动句、被动句的理解特点影响印尼留学生汉语主动句、被动句命题表征项目顺序;这种影响作用与其汉语水平有一定的关系。 相似文献

化学概念表征是化学教育心理学的重要研究对象。化学概念是以命题、表象、产生式和图式等方式表征的。化学概念表征有表象优先性、丰富性、相关性、个体性、可变性等特点。学习者对化学概念理解的本质是形成恰当的心理表征,用“正确度”、“深度”和“速度”等概念,对化学概念的表征可作更为精致的描述。 相似文献

语义启动是研究语义表征的主要范式。在过去的30年里,通过对语义启动效应的研究,词汇的语义表征理论也从符号联结发展到神经联结,其影响因素也逐步重视多方面的交互作用。究其问题,已有研究还存在很多不一致的结论,对语义内在的表征机制和学习机制缺乏深入了解,对影响语义表征的个体因素考虑不多。 相似文献
