与拼音文字不同, 汉字是形义结合更紧密的文字, 因此语音信息在语义通达中的作用一直是汉语加工研究中存在争议的问题。形声字作为汉字的主体(80%), 其声旁在一定程度上提供了字的语音信息, 本文通过两项眼动研究考察了左右结构和上下结构形声字的声旁语音信息对形声字加工的影响。结果发现, 当声旁在右或声旁在下时, 省前与略后条件没有显著差异, 甚至出现差异的逆转, 也就是说当略后的笔画中包含声旁时, 亚词汇层面的声旁语音信息会影响到“笔画顺序效应”, 实验结果说明声旁的语音信息对形声字的加工起到重要作用。 相似文献

In alphabetic languages, prior exposure to a target word's orthographic neighbour influences word recognition in masked priming experiments and the process of word identification that occurs during normal reading. We investigated whether similar neighbour priming effects are observed in Chinese in 4 masked priming experiments (employing a forward mask and 33-ms, 50-ms, and 67-ms prime durations) and in an experiment that measured eye movements while reading. In these experiments, the stroke neighbour of a Chinese character was defined as any character that differed by the addition, deletion, or substitution of one or two strokes. Prime characters were either stroke neighbours or stroke non-neighbours of the target character, and each prime character had either a higher or a lower frequency of occurrence in the language than its corresponding target character. Frequency effects were observed in all experiments, demonstrating that the manipulation of character frequency was successful. In addition, a robust inhibitory priming effect was observed in response times for target characters in the masked priming experiments and in eye fixation durations for target characters in the reading experiment. This stroke neighbour priming was not modulated by the relative frequency of the prime and target characters. The present findings therefore provide a novel demonstration that inhibitory neighbour priming shown previously for alphabetic languages is also observed for nonalphabetic languages, and that neighbour priming (based on stroke overlap) occurs at the level of the character in Chinese. 相似文献

实验采用消失文本范式,操纵注视点上字、词消失单元和呈现时间,探讨字词视觉呈现、字词识别加工对中文阅读眼动过程的影响。结果发现:(1)0 ms延迟时间的消失文本均严重影响总阅读时间,其中单字消失、单词消失与双字消失对阅读效率的影响没有差别;各消失条件都导致较多回视次数;相对于其他消失条件,单字消失和双字消失导致较多的再注视词数。(2)120 ms延迟时间的消失文本均不影响总阅读时间,但会通过取消部分眼跳的方式导致注视持续时间的增加,字消失单元(单字消失和双字消失)迫使读者取消部分词内再注视眼跳。综合两种延迟时间下各消失文本的数据可见,字识别和词汇识别相互影响,词在中文阅读的词内再注视眼跳选择目标环节起到重要作用。 相似文献

电子地图汉字大小辨认阈限和合理字间距 总被引:1,自引:1,他引:0
本研究由三个实验组成,探讨电子地图中汉字呈现的辨认闽限和合理字间距(信息载负量)问题。实验一采用恒定刺激法测定电子地图中汉字的辨认闽限,结果显示,汉字复杂度和背景的复杂度都影响地图汉字识别,且不存在交互作用;宋体汉字的平均辨认阈限为7.0771’。实验二运用调整法测得在电子地图中宋体汉字的舒适阈限(能识别每个笔画的汉字辨认阈限)为16.6951’。实验三以视觉搜索方法研究字间距(体现在电子地图中单位面积字数)与搜索效率的关系,结果显示,每个汉字平均耗费的搜索时间随着字数增加而减少,说明字数越多,搜索效率越高。 相似文献

在中文阅读中, 为了进行词汇识别, 需要对汉字在词中的相对顺序进行加工, 即汉字位置加工。汉字位置加工是词汇识别和阅读理解的重要环节。如果汉字位置未得到加工, 可转置词将很难被区分。可转置词由相同汉字构成, 但每个汉字所处位置不同。以往研究发现, 词内汉字位置加工是比较灵活的; 而且词边界信息会影响汉字位置的加工, 即汉字位置加工存在词边界效应。该效应产生的原因及影响因素有哪些?本项目采用眼动追踪技术, 在自然阅读中系统探讨如下三个问题:(1)词的首/尾汉字如何调节汉字位置加工过程; (2)嵌套词和歧义词边界如何影响汉字位置加工; (3)语境合理性和预测性如何影响汉字位置加工的词边界效应。本项目将为首个中文汉字位置加工模型的建立提供数据支持和科学基础, 推进现有的中文词汇识别和词切分模型的进一步完善, 并为词汇的高效率教授与学习提供科学指导。 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

绕口令效应指无论朗读还是默读,绕口令的阅读时间都长于正常句子的阅读时间。本研究采用Eyelink 2000型眼动仪,通过两个实验考察汉语阅读中的绕口令效应及其对知觉广度的影响。实验1结果表明:与阅读非绕口令相比,绕口令的阅读时间和注视次数均显著增加而阅读速度和平均眼跳幅度均显著下降。实验2结果表明:绕口令的知觉广度为注视点右侧1~2个汉字,控制句的知觉广度为注视点右侧2~3个汉字。结果说明汉语中存在绕口令效应,使读者知觉广度变小,阅读效率下降。。 相似文献

In this study, we investigated the role of visual and phonological information in lexical access of Chinese characters. Homophonic English words have been the main source of stimuli for word recognition research. However, since these stimuli also often look alike, visual and phonological information may be confounded in reported experiments. In contrast, many homophonic Chinese characters are visually distinct. In addition, visually similar characters often have very different pronunciations. These characteristics allow a more controlled investigation of the roles of visual and phonological information in activation of meaning. In the present study, two types of Chinese characters were used in a semantic categorization paradigm: integrated characters, which contain strokes that are not separable; and compound characters, which contain at least two clearly identifiable components. The results show that the recognition of a Chinese integrated character depends primarily on visual information, whereas the recognition of a Chinese compound character relies on visual, phonological, and semantic information. It is concluded that visual information plays a greater role in Chinese character recognition than has previously been documented. 相似文献

Three experiments using Chinese text were conducted to investigate word spacing and its effect on reading performance. In Exp. 1, a sonogram detector was used to analyze interword and intercharacter (within a word) time intervals from text read aloud by professional TV broadcasters versus college graduates. The results showed interword intervals were significantly longer than intercharacter intervals, indicating that interword spacing has psychological reality in speech. Exp. 2 examined the effect on reading performance due to separating the characters that compose a word. Separating the characters of a word did not decrease reading accuracy but did result in significantly longer reading times. Exp. 3 explored the effect of word spacing in Chinese sentences on reading performance. Analysis showed that word spacing did not affect reading accuracy, but half character and whole-character spacing significantly reduced reading time. The results of the present study suggest that word spacing in Chinese text layout enhances reading performance. Word spacing may help the reader to segment more quickly a string of characters into words and reduce the likelihood of misinterpretation. Also, ambiguity of sentence structure severely degraded reading accuracy. The implications of the results for word spacing design in Chinese text are discussed. 相似文献

本研究探讨了汉字词在不同方位与不同排列组合条件下对念读速度与准确性的影响.实验结果表明逆意排列的汉字词处于不同方位(正位、左右倾斜90°、倒位),对汉字词的念读速度产生明显影响.汉字词处于正位时,念读速度最快;其次是处于左斜与右斜90°;对汉字词的念读速度最慢而准确性最低是处于倒位时(汉字词颠倒).汉字词无论是顺意排列或是逆意排列,正位结果均明显优于倒位结果;但汉字词在倒位顺意排列条件下,结果优于正位逆意排列的结果,这表明,字词间的意义联系的作用大于字词方位的作用. 相似文献

采用两个实验探讨同音字密度对于汉字识别的影响。实验一采用命名任务,结果发现高同音字密度的汉字的加工时间短于低同音字密度的汉字,说明在汉字识别中,同音字密度起促进作用;实验二运用眼动分析的方法,考察在句子阅读中的同音字密度效应。结果发现,读者对高、低同音字密度汉字的加工在各眼动指标上均没有显著差异,说明在正常句子阅读中,同音字密度的效应消失。 相似文献

Native Chinese readers' eye movements were monitored as they read text that did or did not demark word boundary information. In Experiment 1, sentences had 4 types of spacing: normal unspaced text, text with spaces between words, text with spaces between characters that yielded nonwords, and finally text with spaces between every character. The authors investigated whether the introduction of spaces into unspaced Chinese text facilitates reading and whether the word or, alternatively, the character is a unit of information that is of primary importance in Chinese reading. Global and local measures indicated that sentences with unfamiliar word spaced format were as easy to read as visually familiar unspaced text. Nonword spacing and a space between every character produced longer reading times. In Experiment 2, highlighting was used to create analogous conditions: normal Chinese text, highlighting that marked words, highlighting that yielded nonwords, and highlighting that marked each character. The data from both experiments clearly indicated that words, and not individual characters, are the unit of primary importance in Chinese reading. 相似文献

使用眼动仪记录汉语发展性阅读障碍儿童、正常年龄匹配和能力匹配儿童阅读插入空格文本时的眼动,考察在字、词以及非词间插入空格呈现文本对汉语发展性阅读障碍儿童阅读加工过程的影响。结果发现,阅读障碍儿童在字间空格条件下平均注视时间减少的程度大于正常儿童,注视次数在字间和词间空格条件下未见显著增加,能力匹配儿童的注视次数在这两种空格条件下却显著增加。结果说明,在字间和词间插入空格能够减少儿童的平均阅读时间,且字间空格文本呈现显著地提高了其阅读效率,说明空格对汉语阅读障碍儿童具有促进作用,这种促进主要是由于空格减少了其视觉拥挤效应所致。 相似文献
