Recent metaphor research has revealed that metaphor comprehension involves both categorization and comparison processes. This finding has triggered the following central question: Which property determines the choice between these two processes for metaphor comprehension? Three competing views have been proposed to answer this question: the conventionality view ( Bowdle & Gentner, 2005 ), aptness view ( Glucksberg & Haught, 2006b ), and interpretive diversity view ( Utsumi, 2007 ); these views, respectively, argue that vehicle conventionality, metaphor aptness, and interpretive diversity determine the choice between the categorization and comparison processes. This article attempts to answer the question regarding which views are plausible by using cognitive modeling and computer simulation based on a semantic space model. In the simulation experiment, categorization and comparison processes are modeled in a semantic space constructed by latent semantic analysis. These two models receive word vectors for the constituent words of a metaphor and compute a vector for the metaphorical meaning. The resulting vectors can be evaluated according to the degree to which they mimic the human interpretation of the same metaphor; the maximum likelihood estimation determines which of the two models better explains the human interpretation. The result of the model selection is then predicted by three metaphor properties (i.e., vehicle conventionality, aptness, and interpretive diversity) to test the three views. The simulation experiment for Japanese metaphors demonstrates that both interpretive diversity and vehicle conventionality affect the choice between the two processes. On the other hand, it is found that metaphor aptness does not affect this choice. This result can be treated as computational evidence supporting the interpretive diversity and conventionality views. 相似文献

A standing challenge for the science of mind is to account for the datum that every mind faces in the most immediate – that is, unmediated – fashion: its phenomenal experience. The complementary tasks of explaining what it means for a system to give rise to experience and what constitutes the content of experience (qualia) in computational terms are particularly challenging, given the multiple realizability of computation. In this paper, we identify a set of conditions that a computational theory must satisfy for it to constitute not just a sufficient but a necessary, and therefore naturalistic and intrinsic, explanation of qualia. We show that a common assumption behind many neurocomputational theories of the mind, according to which mind states can be formalized solely in terms of instantaneous vectors of activities of representational units such as neurons, does not meet the requisite conditions, in part because it relies on inactive units to shape presently experienced qualia and implies a homogeneous representation space, which is devoid of intrinsic structure. We then sketch a naturalistic computational theory of qualia, which posits that experience is realized by dynamical activity-space trajectories (rather than points) and that its richness is measured by the representational capacity of the trajectory space in which it unfolds. 相似文献

This study considered representations of divine and human others in the self-understanding of monotheists from three religions. Self-understanding was conceptualized on the basis of semantic and episodic knowledge in narrative response data. Given the importance of social context in the formation of cognitive schemas, the project emphasized self-understanding in a comparative religious design. The sample included sixty nominated religious exemplars who responded to a structured interview. Schemas were subsequently mapped for Jews, Muslims, and Christians by comparison of self and other representations in a computational model known as latent semantic analysis (LSA). Findings indicated that representation of the divine is far removed from parents in cognitive schemas for all participants. Unlike Jews and Christians, Muslims appear to represent human others on the basis of self-understanding which principally references the divine. When considered in a computational semantic space, exemplars generally represent the self in a manner corresponding with divine and peer figures. 相似文献

通过向被试呈现代表积极情景线索的材料(一段含有互助、和谐信息的公益短片),运用内隐联想测验(IAT)范式,从内隐社会认知的角度来研究积极情境线索对个体内隐攻击性的影响,并分析这种影响是否具有性别差异。结果表明:未观看积极情景线索材料的被试表现出显著的内隐攻击性,而观看积极情景线索材料的被试的内隐攻击性不显著;积极情景线索的主效应显著,且这一效应不存在性别差异。这说明,积极情景线索能有效抑制个体的内隐攻击性,并支持自我攻击信念IAT是测量个体内隐攻击性的有效工具。 相似文献

空间量化(spacial quantification)是空间知觉的基础, 是对特定空间性质的表达。离散量(discrete magnitude)与连续量(continuous quantity)分别反映了空间分立和连续的性质, 二者有着相似的行为效应, 在神经表达上也有部分重叠, 这些证据暗示了二者可能有共同的表征机制——模拟表征(analog magnitude representation)。数量空间映射(number–space mappings)提供了数量与空间关系的直接证据。但空间量化的研究中还有许多未解之谜, 如:空间量化的动态表征、量化机制的普遍性、参照点问题、复杂和多维空间的量化等。在具身认知(embodied cognition)的框架下, 空间量化的心理表征研究将对空间的性质做出更深刻的回答。 相似文献

研究运用DRM范式,以具有语音关联的汉语双字词为材料,采用2(语音类型)×3(词语类型)被试内实验设计,考察汉语双字词语音关联对错误记忆的影响。结果表明:(1)被试对诱饵词的错误再认率显著高于对填充词的错误再认率,说明汉语双字词语音关联能够诱发错误记忆;(2)双字词表与单字词表引发的语音关联性错误记忆效应相当,小于语义及字形关联的错误记忆效应;(3)尾音关联词表中词语再认率高于首音关联词表。 相似文献

反社会行为是一种受基因和环境共同影响的复杂性行为, 但单个基因如单胺氧化酶基因(MAOA)、5-羟色胺转运体启动因子基因(5-HTT)、儿茶酚-o-甲基转移酶(COMT)基因的影响并不能全面解释其产生的分子遗传机制。来自分子遗传学研究取向的方法—— 全基因组关联分析(genome-wide association study, GWAS), 把人类基因组中数以百万计的单核苷酸(SNPs)和复制数变异(CNVs)作为遗传标记, 在全基因组层面上, 开展多中心、大样本的关联研究, 经过反复验证来发现与外在表型相关的基因位点, 为进一步了解反社会行为复杂分子遗传机制提供了重要的线索。未来的研究应该通过科学的实验设计将精确的基因分型技术与心理、环境因素相结合, 实现对复杂性行为或特质的基因-心理-环境模型的成因性分析。 相似文献

作为一种文化构念, 朴素辩证从文化与认知的角度诠释了中国人基于民众理论的思维方式。本研究首次采用内隐联想测验(IAT)的方法测量内隐层面朴素辩证概念与自我以及自我相近概念在东方被试认知中的联结, 探讨东方人内隐层面的辩证自我。文章通过2个IAT实验发现, 中国人将“我”和辩证思维词汇归为一类, 将“非我”和线性思维归为一类时反应速度更快; 且他们将“朋友”和辩证思维词汇归为一类, 将“敌人”和线性思维词汇归为一类时反应速度更快。这表明在内隐层面上, 东方人确实将辩证概念与自我以及自我相近概念联系得更为紧密。 相似文献
