书写是小学阶段书面语发展的重要目标之一,受到多种认知技能的影响。采用追踪研究考察了127名小学五年级儿童的语素意识和快速命名对其五、六年级时的汉字听写和抄写的影响。控制了非言语智力、语音意识后,结果发现:(1)儿童汉字听写和抄写能力随时间发展均有显著增长;(2)五年级语素意识显著预测了五、六年级两个时间点的听写,五年级快速命名仅显著预测了五年级听写;(3)五年级语素意识和快速命名预测了五年级抄写。研究表明语素意识和快速命名对汉字听写和抄写存在不同的影响作用。 相似文献

汉字听写是小学生读写能力的重要组成部分,受多种认知技能影响。以858名小学一至六年级学生为对象,考察了元语言意识(语音意识、语素意识、正字法意识)和快速命名对汉字听写的影响,在控制了智力和口语词汇的影响后,结果发现:(1)语音意识和正字法意识在低年级儿童的汉字听写中起着重要作用,对中、高年级没有显著影响;(2)快速命名在中、高年级儿童的汉字听写中起着独特作用,而对低年级没有显著影响;(3)语素意识对整个小学阶段的汉字听写都起着重要作用。研究结果表明,各认知技能在儿童不同的发展阶段对汉字听写的作用有所不同。 相似文献

自1966年Clay首次提出早期读写能力(Emergent Literacy)的观点以来,对于0—6岁学前儿童读写能力的研究引起了教育学家、心理学家、语言学家的广泛关注和重视,该文首先介绍了早期读写能力的提出与界定.然后具体从社会文化背景、家庭读写环境、幼儿园读写环境三个方面对影响儿童早期读写能力的环境因素进行了分析。最后对目前的研究进行了简单的小结,并指出了在我国进行相关研究的迫切性和重要意义。 相似文献

An 83 year old illiterate, right-handed woman developed a persistent nonfluent aphasia following a right cerebral infarction (crossed aphasia). Computerized axial tomography localized the lesion to the right posterior frontal lobe.It is suggested that the neural mechanisms involved in learning to read and write may be critical for the complete establishment and maintenance of language dominance in the left hemisphere, and that, in this case, the patient's failure to acquire reading and writing skills altered the normal evolution of language lateralization and resulted in the right hemisphere assuming the dominant role. 相似文献

Among a group of 12 persons selected for the ability to write with ease with either hand, none were found to write using a hooked hand posture with either the right or left hand. Tests of verbal and manipulospatial ability indicated a normal balance of these two types of abilities, usually associated with the left and right hemispheres. Findings are discussed in terms of implications for cerebral organization and hand position in writing. 相似文献

以226名将汉语作为第二语言的越南大学一到四年级学生为研究对象,以低频独体字、部件熟悉假字和部件不熟悉假字为材料,采用延迟书写任务,考察了不同年级的越南大学生汉字部件意识的发展及其影响因素。结果发现:(1)学习3个月汉语的大一学生能以部件作为汉字加工单元,其延迟书写部件熟悉假字显著好于低频独体字,并与高年级学生没有差异,说明越南大学生很早就发展出了汉字部件意识;(2)不同年级大学生书写部件不熟悉假字的成绩都显著低于部件熟悉假字,也低于低频独体字,表明部件构字能力是越南大学生汉字书写的重要影响因素。(3)越南大一学生的汉字书写成绩受到汉字结构的影响,左右结构优于上下结构,但其他年级的成绩不受汉字结构的影响。 相似文献

词切分对初学者句子阅读影响的眼动研究 总被引:4,自引:3,他引:1
采用EyeLink II眼动仪,以72名小学三年级学生为被试,通过三个实验来探讨词切分对初学者汉语句子阅读的影响。实验一设置四种空格呈现条件:正常的无空格条件、字间空格条件、词间空格条件和非词空格条件。实验二采用灰条标记作为字、词或非词的边界,使不同条件下句子的空间分布是一致的。实验三进一步操纵了学生的阅读技能。结果发现三个实验的结果趋势是一致的。小学三年级学生在阅读有词间空格的文本和正常的无空格文本一样容易。尽管词切分文本对阅读技能高和阅读技能低的学生来说一样容易,但非词空格呈现条件会对阅读技能低的学生产生更大的干扰作用。阅读技能低的学生在阅读过程中更依赖于文本的低水平视觉线索。文章最后讨论了词切分对建构中文阅读眼动控制模型的启示。 相似文献

Learning Chinese characters may improve visual recall. 总被引:4,自引:0,他引:4
From elementary through high school, Japanese children are required to memorize a large number of distinct visual forms, i.e., roughly 2,000 Chinese characters, and tremendous effort is expended in learning to read and write them. We hypothesized that early training in memorizing Chinese characters and the use of these characters in daily life shapes brain development and facilitates recall of visual forms in general, including geometrical figures in visual recall tests. To demonstrate whether the learning of Chinese character is correlated with specific aspects of memory, we administered the Wechsler Memory Scale-Revised (WMS-R) to a representative sample of the normal Japanese population (316 persons, 100% Japanese) and compared their scores with data previously obtained from a representative sample of the normal U.S. population (316 persons, 82.5% Caucasian). The WMS-R has 12 memory subtests, each measuring a different aspect of memory and includes two visual recall subtests (Visual Reproduction I and II). Compared to the Americans, the Japanese group obtained significantly higher scores on these two visual recall subtests in each of the six age groups tested (16 to 74 years old). Further, the scores of Japanese on the two visual recall subtests did not decline across age groups as much as scores for the U.S. group. Japanese also scored significantly higher on the Visual Memory Span subtest in three age groups. 相似文献

We describe a young woman who suddenly began mirror writing with her right hand and has not reverted to normal writing for more than 6 years, although she writes normally with her left hand. She is ambidextrous, although she had previously used only her right hand for writing and drawing. Since it is much easier for her to use right-handed mirror writing, she uses her left hand only for writing meant to be read by others and her right hand for all other writing. Her hobbies are sculpture and painting, and her chief complaint is migraine accompanied by sensory and perceptive disturbances. 相似文献

采用EyeLink 2000眼动仪,选取四种不同类型的双字词(首字和尾字均为多笔画汉字;首字为多笔画汉字,尾字为少笔画汉字;首字为少笔画汉字,尾字为多笔画汉字;首字和尾字均为少笔画汉字),要求被试阅读包含有目标词的句子,以探讨汉字笔画数对注视位置效应的影响。结果发现,单次注视条件下,读者往往将首次注视定位于词的中心位置,多次注视时首次注视往往落在词的开头部分;但是当首字为多笔画汉字时,相较于首字为少笔画汉字,读者对目标词的首次注视更多地落在词的首字上。首字和尾字笔画数共同影响读者对目标词的再注视概率。研究结果支持“战略-战术”模型。 相似文献
