汉语新词词汇化的眼动研究

本研究采用眼动技术,操纵词类型和熟悉性来探讨汉语新词的词汇化程度。结果发现,新词在眼动早期、晚期加工指标上和词汇词没有显著差异;相比低熟悉新词,高熟悉新词在凝视时间、回视时间及总注视时间上加工时间更短。研究表明部分新词已达到与《现代汉语词典》中词汇词词汇化程度的相同水平,新词与词之间没有严格的界限,熟悉性在新词词汇化过程中起到了主要作用。     

熟练中-英双语者对多义词早期识别中语义和语法的相互作用

以中、英文的多义词为材料, 采用跨语言隐蔽启动的实验范式, 考察在无语境条件下熟练中–英双语者对多义词的早期识别。结果表明：(1)熟练中–英双语者表现出显著的隐蔽翻译启动效应, 当目标词是主要翻译对等词时, 启动效应更加显著。(2)翻译对等词的性质、多义词的义项联系程度以及是否是词类歧义词都影响熟练中–英双语者对中、英多义词的早期加工。(3)在无语境条件下, 词类信息在意义通达的早期就已经激活, 并且同语义信息之间存在着交互作用。根据研究结果, 扩展和修正了分布式概念表征模型。     

Processing of compound-word characters in reading Chinese: An eye-movement-contingent display change study

Readers’ eye movements were monitored as they read Chinese two-constituent compound words in sentence contexts. The first compound-word constituent was either an infrequent character with a highly predictable second constituent or a frequent character with an unpredictable second constituent. The parafoveal preview of the second constituent was manipulated, with four preview conditions: identical to the correct form; a semantically related character to the second constituent; a semantically unrelated character to the second constituent; and a pseudocharacter. An invisible boundary was set between the two constituents; when the eyes moved across the boundary, the previewed character was changed to its intended form. The main findings were that preview effects occurred for the second constituent of the compound word. Providing an incorrect preview of the second constituent affected fixations on the first constituent, but only when the second constituent was predictable from the first. The frequency of the initial character of the compound constrained the identity of the second character, and this in turn modulated the extent to which the semantic characteristics of the preview influenced processing of the second constituent and the compound word as a whole. The results are considered in relation to current accounts of Chinese compound-word recognition and the constraint hypothesis of Hyönä, Bertram, and Pollatsek (2004 Hyönä, J., Bertram, R. and Pollatsek, A. 2004. Are long compound words identified serially via their constituents? Evidence from an eye-movement-contingent display change study. Memory & Cognition, 32: 523–532. (doi:10.3758/BF03195844)[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]). We conclude that word identification in Chinese is flexible, and parafoveal processing of upcoming characters is influenced both by the characteristics of the fixated character and by its relationship with the characters in the parafovea.     

Affective valence of words impacts recall from auditory working memory

Abstract

There is limited evidence on the influence of affective stimuli on auditory working memory. The reported study investigated whether emotional auditory words interfere with ongoing auditory processing of words in auditory working memory. On each trial, words with negative, neutral, and positive affective valence were simultaneously presented on three different speakers. Participants recalled the word presented from the centre speaker first and then recalled the words presented from the side speakers. More negative and positive words compared to neutral words were recalled from the centre speaker. After recall of negative and positive words from the centre speaker, the subsequent first recall of words from the side speakers was reduced, regardless of anxiety level of the participant. The emotional interference effect suggests that emotional words interfere with ongoing central processing due to the attentional dwell on the information in auditory working memory.     

Words and possible words in early language acquisition

In order to acquire language, infants must extract its building blocks—words—and master the rules governing their legal combinations from speech. These two problems are not independent, however: words also have internal structure. Thus, infants must extract two kinds of information from the same speech input. They must find the actual words of their language. Furthermore, they must identify its possible words, that is, the sequences of sounds that, being morphologically well formed, could be words. Here, we show that infants’ sensitivity to possible words appears to be more primitive and fundamental than their ability to find actual words. We expose 12- and 18-month-old infants to an artificial language containing a conflict between statistically coherent and structurally coherent items. We show that 18-month-olds can extract possible words when the familiarization stream contains marks of segmentation, but cannot do so when the stream is continuous. Yet, they can find actual words from a continuous stream by computing statistical relationships among syllables. By contrast, 12-month-olds can find possible words when familiarized with a segmented stream, but seem unable to extract statistically coherent items from a continuous stream that contains minimal conflicts between statistical and structural information. These results suggest that sensitivity to word structure is in place earlier than the ability to analyze distributional information. The ability to compute nontrivial statistical relationships becomes fully effective relatively late in development, when infants have already acquired a considerable amount of linguistic knowledge. Thus, mechanisms for structure extraction that do not rely on extensive sampling of the input are likely to have a much larger role in language acquisition than general-purpose statistical abilities.     

A comparison of two flash-card methods for improving sight-word reading

Flash cards have been shown to be useful for teaching sight-word reading. To date, the most effective flash-card instruction method is incremental rehearsal (IR). This method involves the instructor interspersing unknown stimulus items into the presentation of known stimulus items. In this study, we compared IR to a modified IR procedure-strategic incremental rehearsal (SIR)-to determine whether the effects of IR might be improved by incorporating variables likely to increase word acquisition. These included increased opportunities to respond to unknown stimuli, using learner responding as a basis for changing instructional items, and systematic prompting methods. An A-B-A-B design was used to compare the effects of IR and SIR for increasing sight-word reading with 4 elementary school students. Results indicated that students read more words correctly with SIR than with IR. In addition, similar patterns of responding were seen at a 2-week follow-up.     

Korean deaf adolescents' recognition of written words for taxonomic categories of different levels

Deaf college students seem to have relatively stronger associations from words for taxonomic categories of basic (e.g., snake) to those of super-ordinate (e.g., reptiles) level than vice versa compared with hearing students in word association (Marschark, Convertino, McEvoy & Masteller, 2004). In deciding whether two sequentially presented words for taxonomic categories of different levels are conceptually related, deaf adolescents might therefore have a poorer performance when they see a category name before than when they see it after one of the corresponding exemplar words. Deaf Korean adolescents were found to recognize words for taxonomic categories of super-ordinate level with lower efficiencies than those of basic level. Their accuracy seemed to reflect a reversed typicality effect when they decided that first-presented words for taxonomic categories of basic level were conceptually related to second-presented words for those of super-ordinate level. It was argued that deaf Korean adolescents went through a temporary stage of having iconic representations of several exemplars of the category aroused in working memory before the abstract semantic representation was fully activated when they saw the word for a taxonomic category of super-ordinate level.     

数量对时间知觉的影响——来自汉语数字的证据

本研究的目的在于探讨汉语数字对时间知觉的影响。采用二分试验程序,以400ms和1200ms作为标准短时间和标准长时间,三个实验中屏幕分别呈现阿拉伯数字(1、5和9),汉语小写数字(一五和九),汉语大写数字(壹伍和玖),让被试估计数字的呈现时间更接近于标准长时间还是标准短时间。结果显示三种实验条件下被试均具有低估小数字的呈现时间和高估大数字呈现时间的倾向。这个结果表明汉语数字也会对时间知觉产生影响,汉字形式的数字可以纳入到综合的数量理论体系之中。     

重复知盲效应产生的机制——来自汉语叠词加工的证据

以汉语中的叠词为实验材料,对重复知盲产生机制的类型标记个体化理论和建构理论进行检验。采用RSVP研究范式,在两个实验中让178名被试口头报告列表中出现的所有汉字（全部报告）或列表中最后两个字（部分报告）。结果发现：（1）在呈现速率为128ms和198ms时,完全重复的汉字在全部报告和部分报告任务中均存在RB效应,但在部分报告任务下出现的RB相比全部报告任务的减少了,符合建构理论的假设。（2）在全部报告条件下,不仅重复刺激的正确报告率会降低,而且与重复刺激相关的非重复刺激的正确报告率也会降低。研究表明建构理论比类型标记个体化理论更能解释RB效应的产生机制。     

颜色词素在词义不透明双字词中的语义激活

多词素词的心理表征和和词义激活已成为心理语言学领域的研究热点。目前主要有三种理论:词素分解储存模型、整词储存模型和混合表征模型。针对词义不透明词中词素与整词的关系,利用语义启动和色词干扰的实验范式,对颜色词素在词义不透明双字词中的语义激活进行了研究。结果表明,词义不透明双字词的词素与整词之间存在着心理资源竞争,表现出相互抑制的关系,它们的力量对比随时间变化而改变,出现此消彼长的趋势。研究还表明,多词素词中的词素加工,不仅受词素结构影响,也受词素本身性质影响。由于颜色词素的加工既涉及语义系统,也涉及知觉系统,所以虽然在多词素词中处于附加词素的地位,也具有加工上的优势。
