核心知识系统出现于人类个体发展和种系发展的早期,在人类复杂认知能力的发生发展中起着建构模块的作用。该文以表征物体和数量关系的两类核心知识系统的性质及二者在儿童的“数”概念形成和成人的数学思维中所起的作用为例,综述了以灵长类动物、婴儿、儿童和成人为被试的研究证据,并进而提出了核心知识系统给相关研究带来的若干启示。 相似文献

实验采用两种编码方式和测验类型考查了编码与提取方式的一致性对生成效应的影响。结果显示:(1)在进行字形加工的知觉辨认测验中,生成过程主要依据字形编码的形近字出现了生成效应;主要依据字义编码的反义字没有出现此效应。(2)在依赖字义提取的自由回忆中,形近字和反义字都出现了生成效应。因而编码与提取方式的一致性可能对生成效应有影响。 相似文献

"感"·"象"·"数"--《周易》经传象数观念的哲学人类学释读 总被引:1,自引:0,他引:1
象数观念是<周易>经传乃至易学中的基础和核心观念.历来对象数观念的理解和解释,往往局限于象数观念本身,而对<周易>经传的产生背景、以及其中的另一个重要观念--"感",则关注不够.本文从哲学人类学的视角,在考察<周易>经传的产生背景以及"感"、"象"、"数"三者之间关系的基础上,认为<周易>经传中的象数观念其实是原始时代的感性具体的思维方式及其宇宙观的积淀.具体说来,"数"也是"象",它们本来都是"互渗"或"交感"的中介;换句话说,<周易>经传象数观念的最终依据其实是感;象数因感而蕴涵着向天道观和伦理观发挥的可能性. 相似文献

Adaptation to right-shifting prisms improves left neglect for mental number line bisection. This study examined whether adaptation affects the mental number line in normal participants. Thirty-six participants completed a mental number line task before and after adaptation to either: left-shifting prisms, right-shifting prisms or control spectacles that did not shift the visual scene. Participants viewed number triplets (e.g. 16, 36, 55) and determined whether the numerical distance was greater on the left or right side of the inner number. Participants demonstrated a leftward bias (i.e. overestimated the length occupied by numbers located on the left side of the number line) that was consistent with the effect of pseudoneglect. The leftward bias was corrected by a short period of visuomotor adaptation to left-shifting prisms, but remained unaffected by adaptation to right-shifting prisms and control spectacles. The findings demonstrate that a simple visuomotor task alters the representation of space on the mental number line in normal participants. 相似文献

Verguts and Van Opstal [Verguts, T., & Van Opstal, F. (2008). A colorful walk, but is it on the mental number line? Reply to Cohen Kadosh, Tzelgov, and Henik, Cognition, 106, 558-563] cleverly explained the results of Cohen Kadosh, Tzelgov, and Henik [Cohen Kadosh, R., Tzelgov, J., & Henik, A. (2008). A synesthetic walk on the mental number line: The size effect, Cognition, 106, 548-557] as a result of different association strength between the size of a number and its color in synesthesia. Here we present three challenges to their alternative explanation, and support our original suggestion. 相似文献

The SNARC effect does not imply a mental number line 总被引:1,自引:0,他引:1
In this study, we directly contrast two approaches that have been proposed to explain the SNARC effect. The traditional direct mapping account suggests that a direct association exists between the position of a number on the mental number line and the location of the response. On the other hand, accounts are considered that propose an intermediate step in which numbers are categorized as either small or large between the number magnitude and the response representations. In a magnitude comparison task, we departed from the usual bimanual left/right response dimension and instead introduced the unimanual close/far dimension. A spatial-numerical association was observed: small numbers were associated with a close response, while large numbers were associated with a far response, regardless of the movement direction (left/right). We discuss why these results cannot be explained by assuming a direct mapping from the representation of numbers on a mental number line to response locations and discuss how the results can be explained by the alternative accounts. 相似文献

Jean Baudrillard has posited a theory of ‘the precession of simulacra’, arguing that it is no longer possible to tell the
difference between an image and the meaning it purports to represent because technology allows the image to precede its meaning.
Christa Wolf, while researching Cassandra: A Novel and Four Essays (1984), traveled to Greece and discovered the ways in which language in the rational, Western model of civilization has been
distorted. Both Baudrillard and Wolf are disturbed by the ways in which sign systems can be manipulated and generated, and
both demonstrate the effect this has in the political and cultural arenas. This analysis intends to show how Baudrillard’s
theories play out in Wolf’s narrative, and how Wolf resolves the problems thus posed through the shock of the aesthetic experience,
which forces communication while it defies representation.

从上海两所中等水平幼儿园以年龄班分层随机抽取180名3~6岁儿童为被试,采用个别测查法考察其数感发展状况。结果表明:(1)3~6岁儿童的数感发展存在显著年龄差异,无性别差异;(2)顺数、实物比较和数符号辨认是其表现较好的三项技能,而倒数和序数却表现较差;(3)数感各组成部分发展不同步,倒数,序数和数符号在中班到大班期间发展迅速,而顺数,基数概念,加减理解却在小班到中班期间发展较快。 相似文献

This longitudinal study explored the importance of kindergarten measures of phonological awareness, working memory, and quantity–number competencies (QNC) for predicting mathematical school achievement in third graders (mean age 8 years 8 months). It was found that the impact of phonological awareness and visual–spatial working memory, assessed at 5 years of age, was mediated by early QNC, which predicted math achievement in third grade. Importantly, and confirming our isolated number words hypothesis, phonological awareness had no impact on higher numerical competencies (i.e., when number words needed to be linked with quantities [QNC Level II and above]) but predicted basic numerical competencies (i.e., when number words were isolated from quantities [QNC Level I]), explaining the moderate relationship between early literacy development and the development of mathematical competencies. 相似文献
