数形联觉——数字空间表征研究“新”取向

数字空间表征是人类对数字进行表征的重要方式。数形联觉（number-form synesthesia）是一种数字可以有意识地引起空间知觉的独特现象,与此类似的是非联觉者中广泛存在的无意识的心理数字线（mental number line）现象。两者在行为和脑机制上存在着很多重叠,也存在着值得思考的差异。数形联觉的研究能够提供实质性的行为和脑机制数据,用以解决数字空间表征研究中出现的问题,加强对于数字空间表征的理解;也为更加全面深入地开展进一步研究提供了新的启示,成为数字空间表征研究中值得推崇的新取向。     

熟练中韩双语者同形词的词汇通达机制

采用隐蔽翻译启动范式的词汇决定任务,研究了三类中韩同形词的词汇表征,被试为30名熟练中韩双语者,以翻译方向和词汇类型为自变量。发现中韩双语间存在不对称的隐蔽翻译启动效应,这种不对称性与同形词类型有关;语义的启动效应大于语音的启动效应。说明完全和部分同义同形词的词汇表征是共享的,异义同形词的词汇表征是分离的;中韩双语同形词的词汇表征为双重心理词典模型。研究结果支持了修正层级模型。     

统计概要表征的内容与机制

人类能够快速提取集合刺激中的统计信息, 并形成以集中趋势和变异性为主要内容的统计概要表征。根据注意资源的使用, 统计概要表征的加工方式可分为分布式注意下的整体加工和聚焦注意下的个体加工。两种加工在工作记忆中相互影响, 共同构建了对集合刺激的表征。统计概要表征适用于多种刺激类型, 发生在低水平和高水平加工中, 因而可能是一种普遍的知觉加工方式。未来研究可关注统计概要表征的神经基础及其对决策的影响。     

中学生物理力学问题的分类及表征研究

采用自由分类和标签分类法,以16道中学物理力学应用题为实验材料,探讨不同学业水平中学生对物理问题的分类及表征差异,以及题目陈述方式(有无示意图)对分类的影响.结果发现: (1)自由分类实验中,学优生侧重于按问题的深层特征(物理原理表征)进行分类,学困生侧重于问题的表面特征(文字表征);题目陈述方式对优困生的分类时间和分类表征也有影响. (2)标签分类实验中,学优生的正确分类题目数量显著高于学困生,有示意图下学优生的正确分类题目数量显著高于无示意图下.     

Narrow Structuralism: Paving a Middle Path Between Cummins and Millikan

Millikan [2000] has levelled a number of persuasive criticisms against Cummins's [1996] theory of mental representation. In this paper, I pave a middle path in the debate between Cummins [2000] and Millikan [2000] to answer two questions. (1) How are representations applied to targets? (2) How is the content of a representation determined? The result is a new theory of mental representation, which I call narrow structuralism.     

Resolving defence mechanisms: A perspective based on dissipative structure theory

Theories and classifications of defence mechanisms are not unified. This study addresses the psychological system as a dissipative structure which exchanges information with the external and internal world. When using defence mechanisms, the cognitive‐affective schema of an individual could remain stable and ordered by excluding psychological entropy, obtaining psychological negentropy or by dissipating the energy of self‐presentation. From this perspective, defences can be classified into three basic types: isolation, compensation and self‐dissipation. However, not every kind of defence mechanisms can actually help the individual. Non‐adaptive defences are just functioning as an effective strategy in the short run but can be a harmful approach in the long run, while adaptive defences could instead help the individual as a long‐term mechanism. Thus, we would like to suggest that it is more useful for the individual to use more adaptive defence mechanisms and seek out social or interpersonal support when undergoing psychic difficulties. As this model of defences is theoretical at present, we therefore aim to support and enrich this viewpoint with empirical evidence.     

Distorted body representations in healthy cognition

Delusions and misperceptions about the body are a conspicuous feature of numerous neurological and psychiatric conditions. In stark contrast to such pathological cases, the immediacy and familiarity of our ordinary experience of our body can make it seem as if our representation of our body is highly accurate, even infallible. Recent research has begun to demonstrate, however, that large and systematic distortions of body representation are a normal part of healthy cognition. Here, I describe this research, focusing on distortions of body representations underlying tactile distance perception and position sense. I also discuss evidence for distortions of higher-order body representations, such as the conscious body image. Finally, I will end with a discussion of the potential relations among different body representations and their distortions.     

重要还是笨重?——概念表征对重量具身效应的影响

本研究考察在"重量-重要性"和"重量-灵活性"两种情境下重量具身效应的表现,进而探讨概念表征对具身效应所产生的影响。实验结果表明,在"重量-重要性"情境下,被试认为重鼠标的价格显著大于轻鼠标的价格,并且更容易将重鼠标与高价值货币,轻鼠标与低价值货币建立联系,表现为经典的"重量-重要性"具身效应;而在"重量-灵活性"情境下,被试认为重鼠标的价格显著小于轻鼠标的价格,并且鼠标重量与高低价值货币之间的联系并没有明显倾向性,重量具身效应出现明显变化。研究结果表明,重量具身效应受概念表征的显著影响,该效应的表现不仅取决于对客体重量的经验,更取决于主体如何对重量感进行认知表征。。     

Spicy Adjectives and Nominal Donkeys: Capturing Semantic Deviance Using Compositionality in Distributional Spaces

Sophisticated senator and legislative onion. Whether or not you have ever heard of these things, we all have some intuition that one of them makes much less sense than the other. In this paper, we introduce a large dataset of human judgments about novel adjective‐noun phrases. We use these data to test an approach to semantic deviance based on phrase representations derived with compositional distributional semantic methods, that is, methods that derive word meanings from contextual information, and approximate phrase meanings by combining word meanings. We present several simple measures extracted from distributional representations of words and phrases, and we show that they have a significant impact on predicting the acceptability of novel adjective‐noun phrases even when a number of alternative measures classically employed in studies of compound processing and bigram plausibility are taken into account. Our results show that the extent to which an attributive adjective alters the distributional representation of the noun is the most significant factor in modeling the distinction between acceptable and deviant phrases. Our study extends current applications of compositional distributional semantic methods to linguistically and cognitively interesting problems, and it offers a new, quantitatively precise approach to the challenge of predicting when humans will find novel linguistic expressions acceptable and when they will not.
