Contrasting effects of phonological priming in aphasic word production

Two fluent aphasics, IG and GL, performed a phonological priming task in which they repeated an auditory prime then named a target picture. The two patients both had selective deficits in word production: they were at or near ceiling on lexical comprehension tasks, but were significantly impaired in picture naming. IG's naming errors included both semantic and phonemic paraphasias, as well as failures to respond, whereas GL's errors were mainly phonemic and formal paraphasias. The two patients responded very differently to phonological priming: IG's naming was facilitated (both accuracy and speed) only by begin-related primes (e.g. ferry-feather), whereas GL benefited significantly only from end-related primes (e.g. brother-feather), showing no more than a facilitatory trend with begin-related primes. We interpret these results within a two-stage model of word production, in which begin-related and end-related primes are said to operate at different stages. We then discuss implications for models of normal and aphasic word production in general and particularly with respect to sequential aspects of the phonological encoding process.     

The influence of complexes on implicit learning

A century ago, Jung looked into the unconscious through complexes by using word association tests. Jung wrote, 'modern psychology with its investigation of complexes has opened up a psychic taboo area riddled with hopes and fears', and complexes remain an unexplored taboo area of research. In the present study, we have investigated the influence of complexes on unconscious cognitive processing, in particular on implicit learning. We have found that complexes shown to disturb conscious cognitive processing in fact enhanced the attention of the subjects and their performance on an implicit learning task. These results suggest that complexes are not just abstractions, but have various actual influences on both conscious and unconscious processing.     

四字成语语境中汉字信号监测的警觉研究

成语中某一字出错作为应检测信号,正确成语作为噪音,实验时间为１００分钟,分成五个相等的时间段。结果发现,（１）四种音形条件下平均正检率在第一时间段明显上升然后保持平稳,反应时随时间变化不显著但音异形假在第一阶段与音同形异在第五阶段的反应时间明显长于其余时间阶段。（２）四种音形条件下正检率有差异,从高到低依次为：音同形似、音同形异、音异形似、音异形假．（３）音形与时间段在正确率上无交互作用,在反应时间上存在交互作用。     

The format of representation of recognized words in infants' early receptive lexicon

Eleven-month-olds can recognize a few auditorily presented familiar words in experimental situations where no hints are given by the intonation, the situation, or the presence of possible visual referents. That is, infants of this age (and possibly somewhat younger) can recognize words based on sound patterns alone. The issue addressed in this article is what is the type of mental representations infants use to code words they recognize. The results of a series of experiments with French-learning infants indicate that word representations in 11-month-olds are segmentally underspecified and suggest that they are all the more underspecified when infants engage in recognizing words rather than merely attending to meaningless speech sounds. But underspecification has limits, which were explored here with respect to word-initial consonants. The last two experiments show the way to investigating further these limits for word-initial consonants as well as for segments in other word positions. In French, infants' word representations are flexible enough to allow for structural changes in the voicing or even in the manner of articulation of word-initial consonants. Word-initial consonants must be present, however, for words to be recognized. In conclusion, a parallel is proposed between the emerging capacities to ignore variations that are irrelevant for word recognition in a “lexical mode” and to ignore variations that are phonemically irrelevant in a “neutral mode” of listening to native speech.     

汉字词的正字法深度与阅读时间的研究

采用命名任务探讨了正字法深度对汉字词读音时间的影响。结果发现,（１）正字法深度对汉字词的读音时间有重要影响。对于高频字,汉字的读音反应时的顺序（由快到慢）是规则形声字、象形字、会意字和不规则形声字,但规则形声字、象形字、会意字之间的差异没有达到显著水平,只有规则形声字与不规则形声字之间差异显著。但在低频时,规则形声字与会意字、不规则的形声字,象形字与不规则的形声字的读音反应时的差异均达到显著水平。（２）与单音词相比,多音词的反应时间长,多音词的优势反应与非优势反应的读音时间也存在着显著的差异。（３）高频时,多音双字词与单音双字词差异不显著,低频时双音双字词与单音双字词差异显著,从而显示了语境与词频的双重影响。整个研究表明,对于表意的汉字而言,正字法深度也是存在的,并对汉字词的读音时间产生重要的影响。     

图画与中、英文字词识别加工的比较

通过对不同材料进行加工的比较来探讨人脑的信息加工机制是认知心理学采用的主要研究方法之一。本研究采用了两个实验。实验一比较了图画、中文和英文字词在命名和分类任务中的差异。结果发现:中文是介于图画和英文之间的一种符号系统,在命名任务中,英文反应最快,图画反应最慢,中文居中;而在分类任务中,反应的快慢趋势却截然相反。实验二进一步探讨了言语及非言语信息的表征结构及加工特性,使用了图-图、图-字、字-图、字-字此四种组合材料进行命名一致性和语义分类两种任务,结果发现:字特征组(字-字,字-图)在命名一致性判断任务中的反应优于图特征组(图-图、图-字),而在语义一致性判断任务中则相反,这一结果很难用双编码理论和共同编码理论来解释。语词信息对语音码的接通是直接的,而对语义码的接通却是间接的,图画信息反之,而且由于某种策略产生了图特征组与字特征组的区别。     

时序知觉中词义和位置的stroop效应

本文目的在于探讨时序知觉中是否存在词义与位置Stroop效应。通过时序知觉判断任务,使用中文汉字“先-后”刺激材料,让被试做出时序判断。对反应时的结果显示空间方位、词义位置的匹配关系和时间间隔均存在主效应,空间方位和词义位置匹配关系、空间方位和时间间隔、词义位置匹配关系和时间间隔均存在交互作用。上述结果提示人脑在时序知觉判断过程中存在词义和位置的Stroop效应,该效应可能与时序知觉加工机制有关。     

汉语阅读中的心理词加工

通过两项研究考察了汉语阅读中心理词存在的心理现实性及其加工效率问题。研究1采用词切分任务考察语法知识掌握水平不同的读者词切分的差异,发现他们在词切分上存在很大分歧,语法知识越丰富,词切分差异越小。研究2探讨心理词的加工效率,使用阴影标记目标词,产生四种呈现条件：正常条件、词汇词条件、心理词条件和非词条件,结果发现心理词比词汇词、非词更容易加工。两项研究结果表明汉语阅读的基本信息单元更可能是心理词。     

汉语儿童词语结构意识在阅读理解中的预测作用

以382名小学一、三、五年级学生为被试,进行为期一年的追踪研究,通过分层回归,探索了词语结构意识在儿童阅读理解中作用的发展性变化。结果发现：（1）在控制了性别、瑞文推理、汉字识别、口语词汇以及快速命名和语音意识之后,在三年级T2、五年级和五年级T2发现了词语结构意识对同期阅读理解有独特解释作用,而在一年级、一年级T2和三年级均未发现词语结构意识对同期阅读理解的独特贡献;（2）在控制了性别、瑞文推理、自回归效应以及其他相关变量的作用后,三年级和五年级时的词语结构意识分别对一年后的阅读理解具有独特的预测作用。结果表明,在小学低年级阶段,词语结构意识在阅读理解中的作用还未显现,在小学中高年级阶段,词语结构意识对儿童阅读理解有显著的预测作用。     

词间空格促进从右向左呈现汉语文本的阅读

摘要：为探讨在无阅读经验时,词切分线索是否促进读者的阅读与词汇识别,本研究操纵了阅读方向、词切分线索与目标词的词频。采用眼动仪记录读者的阅读过程。结果发现：阅读方向与词切分线索的交互作用显著,词切分显著地促进了从右向左呈现文本的阅读,但并不影响阅读从左向右呈现的文本;词切分条件下目标词的注视时间显著地短于无词切分条件。表明词切分线索促进了无阅读经验时的阅读,支持词切分线索的促进与文本不熟悉干扰之间权衡作用的假设。
