Effects of contextual diversity on semantic decision and reading aloud: evidence from a word learning study in English as a second language / Efectos de la diversidad contextual en la decisión semántica y la lectura en voz alta: evidencia de un estudio de aprendizaje de palabras en inglés como segundo idioma

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.     

小学儿童规则发现的类比迁移研究

本研究以小学儿童为被试,证实了在策略提示条件下解决规则发现(合取规则和析取规则)的类比问题时,任务难度和表面相似性是影响策略的迁移的重要因素,并且发现小学儿童的思维能力存在着较大的个体差异.他们在问题解决时主要使用单维检验策略,多数小学儿童缺乏较强的元认知监控.     

语篇语境对句子理解的影响：来自N400的证据

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     

Similarity and reluctance to trade

Previous research has shown that after decision makers are endowed with an object, they are reluctant to trade it for an alternative item. This endowment effect can be explained by loss aversion, the tendency to weight losses more heavily than gains. Consequently, there is no reluctance to trade when no true loss is involved. Four studies investigated whether reluctance to trade declines when the trade involves less of a loss—specifically, when one item is traded for another very similar item. Three experiments did not reveal a relation between willingness to trade and the similarity between the two items being traded. A fourth experiment, however, indicated that subjects were quite willing to trade for an identical item, less willing to trade for a similar item, and even less willing to trade for a dissimilar item. Thus, reluctance to trade decreased as the similarity between the endowment and the alternative increased. This result suggests that loss aversion is a function not only of the item being lost but also of the trade itself—that is, of the relation between the two items being traded. © 1998 John Wiley & Sons, Ltd.     

Central-Eastern European Collective Experiences

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.)     

合理性对汉语阅读中双字词语义预视效益的优势作用：眼动研究

语义预视效益(SPB)对于揭示阅读中读者能否从副中央凹提取高水平信息具有重要意义。关于SPB的产生机制仍然存在争议。本研究通过同时操控预视词的合理性和语义相关性考察了二者对汉语阅读中双字词SPB的影响。结果发现,合理性主效应显著,合理预视下目标词的注视时间显著短于不合理预视;语义相关性主效应不显著,未发现二者的交互作用。研究结果支持了语境匹配假说,进一步说明了汉语阅读中预视词的合理性对SPB的优势作用。     

类比归纳的相似性效应和概念效应比较

该文用两个实验比较了类比归纳中的相似性效应和概念效应。预备实验首先检验了实验所使用的人工概念符号的效度。结果显示,研究采用的人工符号能够按照实验要求准确控制被试对概念关系和相似性的估计。预备实验还显示,在只有相似性或概念信息的条件下,人们更加信任概念信息。在正式实验中,相似性信息和概念信息同时呈现,结果显示,在概念信息明确的时候,人会忽略相似性信息;但在相似性信息和明确的时候,人不会忽略概念信息,因此,文章得出结论：概念是类比归纳的基本构成要素。     

任务与字频对汉字阅读中情绪价效应的影响

两个实验均以汉字为材料,采用2×3被试内设计,分别使用语义范畴判断和语音判断任务考察了汉字频率对阅读中情绪价效应的影响。结果发现：在语义任务中,情绪价与字频之间交互作用不显著,低频消极字和积极字的反应时均快于中性字,高频消极字的反应时也快于中性字,但高频积极字与中性字之间无差异。在语音任务中,情绪价与字频之间交互作用显著,低频消极字和积极字的反应时均快于中性字,而高频字的语音通达则不受情绪价的影响。汉字阅读中的情绪价效应不是自动化的过程,会受到字频与任务形式的影响。     

汉字词和图片命名与分类的比较

采用命名与分类任务考察了汉字词和图片命名与分类的特点,揭示义符在汉字词和图片命名与分类中的作用。结果表明,汉字词和图片的命名与分类与拼音文字的词和图片的命名和分类既有共性,又有差异。汉字词和图片的命名与分类具有不对称性：汉字词的命名快于汉字词的分类,图片的分类快于图片的命名。义符对于汉字词和图片的命名与分类的影响具有不对称性：对汉字词的加工有重要影响,对图片的加工无影响;对汉字词的分类有重要影响,对汉字词的命名无影响。被试对有标示类别的义符的词的分类显著快于对无标示类别的义符的词的分类,甚至快于对图片的分类。所以如此,与汉字词的结构特点有关。汉字形声字多用义符来标记事物的类别,提供了重要的类别信息。根据上述结果,作者构建了汉字词和图片认知加工的综合模型
