在数字比较任务中的SNARC效应表明心理数字线具有空间上从左到右的方向性。本研究在两个实验中分别用面积和亮度作为比较刺激来探讨SNARC效应是否存在于面积比较任务和亮度比较任务中。实验结果显示,面积比较和亮度比较任务中存在类SNARC效应。 相似文献

采用ERP技术并运用跨通路延迟反应范式来探讨拓扑性质知觉理论在非注意状态下是否成立,发现存在视觉MMN且视觉系统在非注意状态下对拓扑性质的加工比颜色加工更早,表明与局部属性(颜色)相比,拓扑性质在无意识中优先得到加工,拓扑性质知觉理论在非注意状态下是成立的。 相似文献

A full separation theorem for the derivable rules of intuitionistic linear logic without bounds, 0 and exponentials is proved. Several structural consequences of this theorem for subreducts of (commutative) residuated lattices are obtained. The theorem is then extended to the logic LR
+ and its proof is extended to obtain the finite embeddability property for the class of square increasing residuated lattices. 相似文献

Pace Zagzebski, there is no route from the value of knowledge to a non–reliabilist virtue–theoretic epistemology. Her discussion of the value problem is marred by an uncritical and confused employment of the notion of a "state" of knowledge, an uncritical acceptance of a "knowledge–belief" identity thesis, and an incoherent presumption that the widely held thought that knowledge is more valuable than true belief amounts to the view that knowledge is a state of true belief having an intrinsic property which a state of 'mere" true belief lacks. Her arguments against a "machine–product" conception of knowledge are undermined by these flaws, while the alternative "agent–act" model she recommends is unattractive, at odds with the knowledge–belief identity thesis she favours, and no solution to the problem of the value of knowledge she poses. I end with the observation that her version of virtue–theoretic epistemology points in the direction of cognitive decision–theoretic norms, and I briefly discuss the bearing of this fact upon her viewpoint. 相似文献

All extensions of the modal Grzegorczyk logic Grz possessing projective Beth's property PB2 are described. It is proved that
there are exactly 13 logics over Grz with PB2. All of them are finitely axiomatizable and have the finite model property.
It is shown that PB2 is strongly decidable over Grz, i.e. there is an algorithm which, for any finite system Rul of additional
axiom schemes and rules of inference, decides if the calculus Grz+Rul has the projective Beth property.

The complexity of the satisfiability problems of various arrow logics and cylindric modal logics is determined. As is well known, relativising these logics makes them decidable. There are several parameters that can be set in such a relativisation. We focus on the following three: the number of variables involved, the similarity type and the kind of relativised models considered. The complexity analysis shows the importance and relevance of these parameters. 相似文献

We consider the problem of the product finite model property for binary products of modal logics. First we give a new proof for the product finite model property of the logic of products of Kripke frames, a result due to Shehtman. Then we modify the proof to obtain the same result for logics of products of Kripke frames satisfying any combination of seriality, reflexivity and symmetry. We do not consider the transitivity condition in isolation because it leads to infinity axioms when taking products. 相似文献

量子决策模型是近10年来提出的一种新型决策模型, 用以解释那些违背经典决策模型的现象。虽然当前的量子决策模型能够解释囚徒困境中的分离效应, 但其中却存在一些困难, 即会产生反常的概率关系以及无法精确拟合分离效应量较大的实验结果。本研究在分析当前量子决策模型困难的基础上, 结合齐当别思想对模型进行改进和优化。结果表明, 研究所构建的量子决策模型克服了当前模型中的困难, 并且能够预测囚徒困境博弈中由他人收益差距改变而引起的分离效应变化趋势。本研究还是一次启发式决策模型与计算式决策模型相结合的探索。 相似文献
