连贯阅读中文本表征的意识性研究

采用独立记得-知道范式(IRK)和加工分离范式(PDP)探讨连贯阅读中文本表征的意识性问题。实验1使用独立记得-知道范式(IRK),分析被试对再认项目判断为“记得”或“知道”的比例（击中率）;实验2使用加工分离范式(PDP),分析被试在包含、排斥测验中的击中率和虚报率。总的实验结果表明,在连贯阅读中,命题表征的建构是无意识的,情境模型的建构也是无意识的,该结果支持和完善了文本阅读双加工理论。     

中文阅读中词切分的认知机理述评

大量的认知科学研究表明, 词在阅读认知加工过程中起着非常重要的作用。因此在阅读中一个重要的过程就是把词从文本中切分出来。有别于英文等拼音文字, 中文文本的词之间没有空格分隔。在没有空格辅助的条件下, 中文阅读者是如何进行词的切分呢？本文主要综述了近期认知心理学和计算机科学领域针对该问题的研究进展, 主要包括：1)介绍了一些词作为整体进行加工的心理学证据; 2)报告了词切分的认知机理方面的研究现状和一个中文词切分和识别的模型; 3)简要回顾了计算机科学中的词切分研究, 并指出了与心理学中词切分研究的区别和联系; 4)提出了一些尚待解决的问题和研究展望, 这些问题的提出和解决将可能促进中文词切分的认知机理全面理解。     

Intrinsic reading motivation of Chinese preschoolers and its relationships with home literacy

The relationship between intrinsic motivation and home literacy of preschoolers was explored. One hundred and seventy-seven preschool children (3.8 to 6.6 years old) in Mainland China and one of the parents who primarily took care of each child participated in the study. Six indicators were considered as a measure of home literacy. Results showed that after controlling for parents' education level and children's age, three home literacy indicators-parental model of reading behaviour, number of books, and years of character teaching-could explain children's intrinsic reading motivation. Contrary to previous Western studies, Chinese children's freedom of book choice was not related to their intrinsic reading motivation. Results are discussed in the context of culture differences.     

汉语儿童在阅读语境中学习英语词汇的效果及影响因素

以71名五年级汉语儿童为被试,让他们在阅读一篇英文材料的过程中对目标词的含义进行推测,并对单词的语境线索强度、个体的推理能力、工作记忆和词汇水平进行测查,从而对汉语儿童是否能够通过阅读习得英文生词以及影响学习效果的因素进行探讨。结果发现：五年级汉语儿童能够在英文阅读中习得生词的含义,学习的可能性达到30％;语境线索强度和被试的词汇水平可影响儿童在阅读语境中学习英语生词的效果。     

不同阅读水平儿童中央执行系统比较研究

本研究通过两部分实验探讨汉语发展性阅读障碍儿童与正常儿童中央执行系统的容量差异和这种差异的性质。通过比较匹配生理年龄的不同阅读水平儿童在自定步速和固定步速的复杂阅读广度测验中的成绩,发现发展性阅读障碍儿童在两种阅读广度测验中都表现出中央执行系统容量的缺陷,这种缺陷既不能用加工效率理论,也不能用资源分配理论来解释,而符合一般容量假设。因此,本研究支持发展性阅读障碍儿童存在实时加工和存储信息的一般容量缺陷。     

汉语儿童正字法意识的萌芽与发展

以474个幼儿园中、大班和小学一到三年级学生为研究对象,通过对70个线条图、位置错误非字、部件错误非字、假字和真字进行字典判断,探讨汉语儿童正字法意识的萌芽、发展及其与识字量之间的关系。结果发现:(1)汉语儿童正字法意识是从无到有、逐步发展的。学前处于萌芽状态,一年级儿童则已具备了一定的正字法意识,并随着年级增加而不断发展。(2)正字法意识分为多个层次,学前阶段只能发展区分汉字和线条图的基本能力,位置意识和部件意识要在入学后才能逐步发展,并且前者的获得比后者容易。(3)正字法意识的发展要以一定的识字量为基础,阅读能力在发展的不同阶段,分别与正字法意识的不同层面密切相关。     

Cognitive development, reading and prosodic skills in children with cochlear implants

This report summarizes some of the results of studies in our laboratory exploring the development of cognitive, reading and prosodic skills in children with cochlear implantation (CI). The children with CI performed at significantly lower levels than the hearing comparison group on the majority of cognitive tests, despite showing levels of nonverbal ability. The differences between children with CI and hearing children were most pronounced on tasks with relatively high phonological processing demands, but they were not limited to phonological processing. Impairment of receptive and productive prosody was also evident in children with CI. Despite these difficulties, 75% of the children with CI reached a level of reading skill comparable to that of hearing children. The results are discussed with respect to compensation strategies in reading.     

Is there an alternative cerebral network associated with enhanced phonological processing in deaf speech-users? An exceptional case

Most people born deaf and exposed to oral language show scant evidence of sensitivity to the phonology of speech when processing written language. In this respect they differ from hearing people. However, occasionally, a prelingually deaf person can achieve good processing of written language in terms of phonological sensitivity and awareness, and in this respect appears exceptional. We report the pattern of event-related fMRI activation in such a deaf reader while performing a rhyme-judgment on written words with similar spelling endings that do not provide rhyme clues. The left inferior frontal gyrus pars opercularis and the left inferior parietal lobe showed greater activation for this task than for a letter-string identity matching task. This participant was special in this regard, showing significantly greater activation in these regions than a group of hearing participants with a similar level of phonological and reading skill. In addition, SR showed activation in the left mid-fusiform gyrus; a region which did not show task-specific activation in the other respondents. The pattern of activation in this exceptional deaf reader was also unique compared with three deaf readers who showed limited phonological processing. We discuss the possibility that this pattern of activation may be critical in relation to phonological decoding of the written word in good deaf readers whose phonological reading skills are indistinguishable from those of hearing readers.     

Curriculum-based measurement of oral reading: Passage equivalence and probe-set development

Curriculum-based measurement of reading (CBM-R) is used to estimate oral reading fluency. Unlike many traditional published tests, CBM-R materials are often comprised of 20 to 30 alternate forms/passages. Historically, CBM-R assessment materials were sampled from curricular materials. Recent research has documented the potentially deleterious effects of poorly controlled alternate forms on CBM-R outcomes. The purpose of this study was to examine alternate procedures for the selection of passages that comprise CBM-R passage-sets. The study examined four procedures for the evaluation and selection of passages, including random sampling, Spache readability formula, mean level of performance evaluation, and Euclidean Distance evaluation. The latter two procedures relied on field testing and evaluation of student performance. Each of eighty-eight students in second- and third-grade were administered 50 CBM-R passages. Generalizability and dependability studies were used to examine students' performance on these passages and evaluate CBM-R passage selection procedures. Results provide support for the use of field testing methods (i.e., calculating performance means and Euclidean Distances) for passage selection. Implications are discussed for future research and practice.
