句子背景下缺失音素的中文听觉词理解的音、义激活进程（Ⅰ）

听觉词的语义激活过程是认知心理学和心理语言学的热点问题。近期出现了两种假设：（1）全部通达理论;（2）语义背景依赖假设。采用缺失音素的中文双字词为材料,考察了中文听觉词的语音、语义激活进程。实验1考察了影响缺失音素的中文听觉词语音、语义激活的因素;实验2考察了在听觉词理解初期,词义提取是否存在句子背景效应。结果表明：（1）对缺失音素的中文听觉词识别受听觉词语音和句子语义背景影响;（2）句子语义背景在缺失音素的中文听觉词识别之初就开始发挥作用,并一直影响着中文听觉词的理解。     

汉语发展性阅读障碍亚类型的初步探讨

以阅读水平匹配组为参照对29名汉语发展性阅读障碍儿童的认知缺陷模式进行了分析,并考察了不同亚类型阅读障碍儿童的汉字识别模式。结果表明汉语发展性阅读障碍存在不同的亚类型,以语音缺陷型、快速命名缺陷型及两者结合的双重缺陷型为主,与英语国家研究中的双重缺陷假设一致。语音缺陷型儿童汉字识别时有更多的语义错误,对声旁中的部分语音线索不敏感;快速命名缺陷型儿童汉字识别时依赖声旁语音线索,表现出阅读发展的一般延迟;双重或多重认知缺陷型是阅读损伤最严重的亚类型     

汉语词汇产生中语义、字形和音韵激活的时间进程

通过图画－词汇干扰实验范式探索汉语单字词产生中语义、字形和语音激活的时间进程。实验一和实验二的结果综合表明：当SOA为-300 ms~0 ms时,存在语义抑制效应,当SOA为-100 ms~100 ms时,存在字形促进效应,当SOA为100 ms时,存在语音促进效应。实验结果支持交互激活理论的观点。实验成功地分离了字形促进效应和语音促进效应,确定了语义、字形和语音这三种信息在汉语口语词汇产生中通达的先后次序,讨论了字形信息在词汇产生中的重要作用,以及被试是否在实验中使用了策略。     

汉字识别中形音义激活时间进程的研究(Ⅰ)

分别采用基于语义的和基于语音的启动范畴判断作业,在不同的SOA条件下,考察高频汉字识别中形音义信息激活的相对时间进程。两个实验的结果表明,高频汉字形音义激活的时序为字形—字义—字音的顺序。这一结果揭示,高频汉字字义的提取更符合直通理论的预期。高频汉字的语音是自动激活的,但语音的激活可能发生在字义通达之后。     

方言经验对早期沪语儿童汉语语音意识的影响

已有研究对汉语儿童的英语语音意识进行研究,且取得了很多有价值的研究成果,但对方言儿童的汉语语音意识的研究很少。汉语是一种具有众多方言的独特语言,许多方言和标准语的语言体系有着显著差异。具有方言和普通话早期经验的双语儿童在汉语语音意识上是否存在优势,有两种不同的看法：一是从心理语言学层面上,母语学习中获得的语言能力或普遍语法能促进第二语言的学习;二是从语言学层面上来讲,母语对第二语言的学习存在干扰作用。那么双语儿童在汉语语音意识上比单一普通话儿童是否存在优势呢？本研究将进行调查。实验选取72名4岁、5岁和6岁学前儿童为被试,每个年龄组各24人,其中沪语儿童和单一普通话儿童各12名。采用听觉呈现方法对所选被试进行汉语语音意识水平的测试,包括声调意识、声母意识和韵母意识三部分,并收集儿童的口语资料。结果表明: 虽然沪语儿童声母意识和韵母意识主效应不显著,但沪语儿童语音意识总成绩和声调意识成绩均比单一普通话儿童高;沪语儿童汉语语音意识优势不受年龄的影响。本研究启示是,上海地区学前儿童学习标准语（普通话）之外应鼓励使用沪语。     

Time course analyses of orthographic and phonological priming effects during word recognition in a transparent orthography

In opaque orthographies, the activation of orthographic and phonological codes follows distinct time courses during visual word recognition. However, it is unclear how orthography and phonology are accessed in more transparent orthographies. Therefore, we conducted time course analyses of masked priming effects in the transparent Dutch orthography. The first study used targets with small phonological differences between phonological and orthographic primes, which are typical in transparent orthographies. Results showed consistent orthographic priming effects, yet phonological priming effects were absent. The second study explicitly manipulated the strength of the phonological difference and revealed that both orthographic and phonological priming effects became identifiable when phonological differences were strong enough. This suggests that, similar to opaque orthographies, strong phonological differences are a prerequisite to separate orthographic and phonological priming effects in transparent orthographies. Orthographic and phonological priming appeared to follow distinct time courses, with orthographic codes being quickly translated into phonological codes and phonology dominating the remainder of the lexical access phase.     

A Comparison of Phonological Awareness Skills in Early French Immersion and English Children

This 2-year study examined the effects of early second language exposure on phonological awareness skills. Syllable, onset-rime and phoneme awareness skills of 72 anglophone children attending English or French immersion programs in primary and grade 1 were investigated. Three-way mixed ANOVAS revealed the following effects and interactions. In terms of grade effect, grade 1 students performed significantly better than primary students on phoneme and onset-rime tasks. A stimulus language effect was observed for the three levels of phonological awareness. All children performed better on English tasks than on French ones. Interaction effects of stimulus language by program were revealed for phoneme as well as syllable tasks. Posthoc analyses revealed that French students performed better on English phoneme and syllable tasks than on French, while English students performed better than French immersion students on French syllable tasks. Correlational analyses revealed significant relationships between reading and phoneme and onset-rime phonological awareness tasks regardless of program of instruction (English, French immersion) or language of reading test (English, French). Syllable awareness was only significantly correlated with the French non-word reading task for the French immersion students.     

Behavioral treatment of children with phonological disorder: the efficacy of vocal imitation and sufficient-response-exemplar training

This study examined whether sufficient-response-exemplar training of vocal imitation would result in improved articulation in children with phonological disorder, and whether improved articulation established in the context of vocal imitation would transfer to other verbal classes such as object naming and conversational speech. Participant 1 was 6 years old and attended first grade in a regular public school. Participant 2 was 5 years 4 months old and attended a public kindergarten. Both participants had normal hearing and no additional handicaps. A multiple baseline design across behaviors (target sounds or blends) was employed to examine whether the vocal imitation training resulted in improved articulation. Results showed that both participants improved articulation once training was implemented, and that the improved articulation transferred from vocal imitation to more natural speech such as object naming and conversational speech. Improvement established during training was maintained posttraining and at a 6-month follow-up.     

Silent letters and phonological priming

Many written English words contain silent letters. Omitting them produces nonwords pronounced identically to the original words, for example, SALM for PSALM and COLUM for COLUMN. We report two naming and two lexical decision experiments in which targets of 4–11 letters followed primes exposed for 100 ms in mask-prime-mask-target sequences. Priming in SALM-psalm and COLUM-column pairs exceeded priming in orthographic control pairs such as ASTA-pasta and COUSI-cousin, pairs in which pronounced letters are omitted to form the primes. SALM and COLUM, however, were less effective primes than PSALM and COLUMN. Results were discussed in terms of the phonological coherence hypothesis, the role of orthographic codes in filtering phonologically activated representations, and graphemes as reading units.
