This experiment investigated contextual diversity effects on novel word learning in English as a second language (L2). A group of advanced English speakers, whose native language was Spanish, participated in the study. Participants learned the meaning of real but obscure words that were embedded in either two or 12 different sentences and learned over two days (frequency of exposure was kept constant). On day three, participants were tested using reading aloud and semantic decision tasks. The results showed that participants learned the meaning of words in both conditions fairly well as revealed by their accuracy in the semantic decision task. However, words experienced in 12 different contexts generated more accurate and faster reaction times (RTs), suggesting the acquisition of more robust semantic representations. Strikingly, reading latencies were also faster for the 12-sentence condition, which might imply that semantics has an effect on reading newly learned words in English as a second language. These results are discussed and accommodated in view of the DRC and the PDP models of single-word reading. 相似文献

Although memories about a nation's past usually are semantic in nature, a distinction needs to be made between lived and distant semantic collective memories. The former refers to memories of community-relevant events occurring during the lifetime of the rememberer, whereas the latter to memories of distant events. Does the content of lived and distant semantic collective memories differ? Employing both free and cued recall, we examined the memories of younger and older Argentines of the Military Junta of 1976. We also examined the effects of political ideology. Content analysis indicated that (1) lived semantic collective memories were more likely to contain personal recollections than distant semantic collective memories, even though those with distant semantic collective memories could have incorporated memories of the parent's personal experience in their recollections, (2) lived semantic collective memories contained more causal statements, and (3) those on the Right with distant semantic collective memories were more likely to claim that they “Don't know” or offer positive accounts of the Junta, suggesting a need to “defend” the reputation of those on the Right. The results are discussed in terms of the goals and plans different generations might have when recollecting their nation's past. 相似文献

In distributional semantics models (DSMs) such as latent semantic analysis (LSA), words are represented as vectors in a high-dimensional vector space. This allows for computing word similarities as the cosine of the angle between two such vectors. In two experiments, we investigated whether LSA cosine similarities predict priming effects, in that higher cosine similarities are associated with shorter reaction times (RTs). Critically, we applied a pseudo-random procedure in generating the item material to ensure that we directly manipulated LSA cosines as an independent variable. We employed two lexical priming experiments with lexical decision tasks (LDTs). In Experiment 1 we presented participants with 200 different prime words, each paired with one unique target. We found a significant effect of cosine similarities on RTs. The same was true for Experiment 2, where we reversed the prime-target order (primes of Experiment 1 were targets in Experiment 2, and vice versa). The results of these experiments confirm that LSA cosine similarities can predict priming effects, supporting the view that they are psychologically relevant. The present study thereby provides evidence for qualifying LSA cosine similarities not only as a linguistic measure, but also as a cognitive similarity measure. However, it is also shown that other DSMs can outperform LSA as a predictor of priming effects. 相似文献

N400作为语义违反的特异性ERP组分,其波幅反映了语义整合加工过程的难度,因此可将其作为研究语篇语境意义建构过程的一项重要指标。语篇语境可分为语言语境和非语言语境。前人一系列基于语篇水平的N400研究表明,从语义的角度上看,语言语境对句子理解具有制约和协调作用,其机制涉及词汇语义启动、场景适宜性、文字内容信息以及因果推理等方面;非语言语境对句子理解具有制约和补充作用,但其机制尚不明确。两种不同来源的语义信息在实时理解中是同时得到加工的 相似文献

The social-psychological phenomena in the post-communist countries of Central-Eastern Europe can be understood only if studied in terms of their pre-communist past. These countries have a complex history. The events relating to dictatorship, democracy and nation are particularly conspicuous. The present study examines the meanings of the terms ‘dictatorship’, ‘democracy’ and ‘nation’ in Hungary, from 1973 until 1995, using the semantic differential. It is argued that the changes in the meanings of these terms can be explained in terms of socio-political changes in Hungary. (© 1997 by John Wiley & Sons, Ltd.) 相似文献

Appraisal theories of emotion, and particularly the Component Process Model, claim that the different components of the emotion process (action tendencies, physiological reactions, expressions, and feeling experiences) are essentially driven by the results of cognitive appraisals and that the feeling component constitutes a central integration and representation of these processes. Given the complexity of the proposed architecture, comprehensive experimental tests of these predictions are difficult to perform and to date are lacking. Encouraged by the “lexical sedimentation” hypothesis, here we propose an indirect examination of the compatibility of the theoretical assumptions with the semantic structure of a set of major emotion words as measured in a cross-language and cross-cultural study. Specifically, we performed a secondary analysis of the large-scale data set with ratings of affective features covering all components of the emotion process for 24 emotion words in 27 countries, constituting profiles of emotion-specific appraisals, action tendencies, physiological reactions, expressions, and feeling experiences. The results of a series of hierarchical regression analyses to examine the prediction of the theoretical model are highly consistent with the claim that appraisal patterns determine the structure of the response components, which in turn predict central dimensions of the feeling component. 相似文献

服务型领导被以往大量研究证实能够对下属产生积极的影响效果。然而, 我们对服务型领导如何影响领导者自己还知之甚少。基于此, 文章根据工作-家庭资源模型, 探讨了服务型领导的收益与代价。采用经验抽样法, 对广州市76名企业单位中的主管进行为期5天的日记研究, 并运用多层线性模型进行数据分析。结果表明:主管每日从事服务型领导行为既可以产生更多的积极情绪, 从而改善工作-家庭关系, 又可能会引发资源损耗, 从而恶化了工作-家庭关系。主管感知的组织支持是服务型领导行为双刃剑效应的“门阀”, 当主管感知到高的组织支持时, 从事服务型领导行为会带来更多的积极情绪, 而当主管感知到低的组织支持时, 从事服务型领导行为可能更容易增加资源损耗。以上结果能拓宽我们对服务型领导影响效果的认识, 并为如何干预服务型领导行为提供一些新的启发。 相似文献

读者能够从副中央凹中提取到什么类型的信息, 是当前阅读眼动研究领域关注的焦点问题.当前普遍认为低水平信息(如正字法信息)可以在副中央凹中得以加工, 但是高水平的信息(如语义和句法信息)能否从副中央凹中进行提取存在争议.本文总结了近年来高水平信息在副中央凹加工的研究进展, 包括拼音文字和非拼音文字(如中文)阅读过程中语义和句法预视效益的研究现状及影响因素, 当前眼动控制模型(如E-Z读者和SWIFT)对预视效益的解释和不足之处, 最后提出未来关于语义和句法预视加工的研究方向. 相似文献
