【摘要】：数量认知是人类重要的认知能力之一。在过去的数十年间,人们对于各种各样的数量形式及其在人脑中的表征进行了研究。顶内沟的一部分神经元被认为以一致的激活模式加工不同的数量形式。不同符号数字的V形启动模式和梯型的符号交叉启动效应暗示着认知系统对不同的数量形式采取共享的、一致的内部表征。距离启动效应被认为是该内部表征的重要功能。最近,涌现出不少新的证据表明数量的抽象化表征可能有更加复杂的过程。研究者关注在共享的内部表征中,是否能够出现符号特异性表征机制的问题,甚至有人怀疑一致的内部表征是否存在。本研究向被试呈现估数stroop图片作为启动刺激,该启动刺激包含着非符号数量和数字符号两种信息。在三个实验中,目标物分别为圆点、阿拉伯数字或汉语数字,45名被试被要求对目标物的数量或者数值进行语音判断。所有的数量为1-5,大多数在感数(subtizing)范围内。实验程序与Roggeman等人的数量启动实验保持一致：在前后掩蔽(49ms)之间,呈现启动刺激83ms,目标物呈现183ms,心理学反应盒记录下被试的语音判断反应时。在实验一中,启动数字对于圆点数量目标物没有任何启动效应。启动数量和目标物数量的某种关系影响了反应时,回归分析结果显示为V形启动效应,然而,在去掉数量距离为0的数据后,回归分析相关的系数的显著性消失了。表明实验一中启动数量的启动效应表现为本值启动。在实验二、三中,启动数量对于目标物没有表现出启动效应,而启动数字对于阿拉伯数字目标物和汉语数字目标物的启动都表现出本值启动效应。表明在该启动条件下,阿拉伯数字的启动表现出语义表征,即数字距离效应的缺失。实验结果表明,数量的本值启动效应是符号特异性表征的结果。同时还发现了阿拉伯数字的距离表征的缺失,这种缺失并非由于字形、语音的加工受限,可能仅与符号数字的语义表征困难有关。实验结果表明阿拉伯数字的语义表征与非符号数量的自动化加工存在共享的认知资源,在该认知功能区内,不同数量形式的表征可以是符号特异性的。
[Abstract]:Quantitative cognition is one of the most important cognitive abilities of human beings. In the past few decades, various quantitative forms and their representation in the human brain have been studied. Some of the neurons in the intra parietal sulcus are thought to process different quantitative forms in a consistent activation mode. The V-shaped starting mode of different symbol numbers and the trapezoidal cross-start effect imply that the cognitive system takes a shared and consistent internal representation of different quantitative forms. The distance priming effect is considered to be an important function of the internal characterization. Recently, new evidence has emerged that quantitative abstractions may have more complex processes. Researchers are concerned about whether the symbol-specific representation mechanism can be found in shared internal representations, and some even doubt the existence of consistent internal representations. In this study, the estimated stroop images were presented to the subjects as priming stimuli, which contained two kinds of information: the number of non-symbols and the number of digital symbols. In three experiments, 45 subjects were asked to make phonological judgment on the quantity or value of the object. All the numbers ranged from 1 to 5, most of them in the range of (subtizing). The experimental procedure was consistent with the quantitative priming experiment of Roggeman et al. Between 49ms, the priming stimulus was 83 Ms, the target was 183 Ms, and the psychological response box recorded the speech judgement response time of the subjects. In experiment 1, the starting number has no priming effect on the number of dots. When the relation between the number of starters and the quantity of the target affected the reaction, the regression analysis showed that the effect was V-shaped. However, when the number distance was 0, the correlation coefficient of the regression equation disappeared significantly. The results show that the priming effect of the number of primer in experiment 1 is primordial priming. In the second and third experiments, the number of primer has no priming effect on the target, but the priming number shows the priming effect on both the Arabic numerals and the Chinese numerals. It is shown that under this condition, the initiation of Arabic numerals shows semantic representation, that is, the absence of digital distance effect. The experimental results show that the priming effect of quantity is the result of symbolic specificity. At the same time, the absence of distance representation of Arabic numerals, which is not due to glyph and limited speech processing, may only be related to the difficulty of semantic representation of symbol numbers. The experimental results show that there are shared cognitive resources between the semantic representation of Arabic numerals and the automatic processing of non-symbolic numbers. In this cognitive functional region, the representation of different quantitative forms can be symbolic specific.
