主观声旁家族对汉语儿童汉字命名的影响

研究选取三年级、五年级和七年级学生,采用两个汉字命名实验,考察主观声旁家族对汉字命名的影响。实验一操纵主观声旁家族大小,发现三年级儿童没有表现出家族效应;五年级儿童表现出边缘显著的家族抑制效应,即对大家族的字命名更慢;七年级儿童表现出显著的家族抑制效应。实验二操纵了目标字是否有高频家族成员字（higher frequency neighbors,HFNs）这个变量,发现儿童普遍都表现出HFNs抑制效应,即对有高频家族成员字的目标字命名更慢。以上结果表明随着年级增长,主观声旁家族对儿童命名的影响逐渐增强,且高年级儿童已表现出家族抑制效应,这一表现与普遍出现的HFNs抑制效应有关。     

形旁家族、声旁家族和高频同声旁字对形声字识别的影响

通过3个实验,考察形旁家族、声旁家族和高频同声旁字对汉字形声字识别的影响。实验1考察形旁家族大小及声旁语音信息的作用。实验2和实验3考察声旁家族大小和高频同声旁字的作用。结果发现,形旁家族和声旁家族大对形声字识别起促进作用;高频同声旁字在使用假字时起抑制作用,在使用非字时无作用;在使用假字时,形旁家族小时识别声旁不可发音的字快于识别声旁可发音的字。研究结果支持字词识别的交互激活模型     

声旁家族大小和高频同声旁字对汉字命名的影响

该研究探讨了声旁家族大小和高频同声旁字对汉字命名的影响。结果表明：1）声旁家族大起抑制作用,在不一致字上更明显;2）相对于高频同音邻近字,高频异音邻近字对低频字起抑制作用;3）汉字命名中字形相近字的作用点有两个,分别在字形表征水平和语音表征水平。     

三、五年级儿童形声字识别中形旁和声旁家族效应

采用2（年级）×2（声旁家族大小）×2（形旁家族大小）三因素混合实验设计,在形声字识别中考察了三、五年级儿童的形旁和声旁家族效应。结果仅在三年级中发现了显著的形旁家族大小效应,而五年级中却没有发现。但两个年级中形旁和声旁家族的交互作用均显著。进一步分析发现在声旁处于大家族时,形旁也处于大家族时,三、五年级儿童的反应时更快。此结果说明声旁和形旁家族共同影响形声字识别,但在三年级儿童中,形旁家族效应可以不依赖于声旁家族单独发挥作用,五年级儿童中却没有独立的形旁家族效应。     

儿童汉字读音声旁一致性意识的发展

采用同音判断的方法,考察儿童对汉字读音声旁一致性意识的发展。一个熟悉字和一个不熟悉字共用同一个声旁,该声旁在提示整字发音时可以是一致的,即包含此声旁的所有汉字都发音相同,也可以是不一致的。要求儿童猜测不熟悉字的读音,作出它与熟悉字“是”、“否”同音的判断。结果发现,儿童很早就意识到汉字的结构以及声旁和形旁在表音、表义功能上的分工。随着年级的升高,声旁一致性对猜测不熟悉汉字读音的影响增强。小学四年级语文能力较高的儿童已经开始意识到声旁的一致性;六年级儿童总体上说来已发展了一致性意识。初二年级的学生发展了声旁一致性意识,且没有能力差异。大学生的声旁一致性意识最强。     

书面字形在汉语低年级儿童口语词汇学习中的作用

采用配对联想学习范式, 通过2个实验, 系统考察了书面字形在汉语低年级儿童口语词汇学习中的作用。实验一以40名二年级学生为研究对象, 控制了假字的形旁透明度, 操纵了声旁的规则性, 要求儿童分别在规则字、不规则字和无字形条件下学习4个新异物体的名称, 结果发现呈现不规则汉字阻碍了儿童口语词汇的学习;实验二以27名一年级学生为研究对象, 采用相同的配对联想学习范式, 同时操纵了假字的声旁规则性和形旁透明度, 再次发现了不规则汉字的阻碍效应, 并且发现透明形旁对口语词汇学习的促进作用。整个研究表明, 书面字形在汉语儿童口语词汇学习中具有重要作用, 这对今后的教学实践和理论研究都具有重要启示意义。     

汉字识别中的语音效应

该实验用启动掩蔽法探讨了汉字词识别中语音的作用。以五类高、低频汉字词对为材料,在三种启动时间条件下发现:高频形似音同目标字在25毫秒启动下有显著促进效应,而形异音同目标字在25和35毫秒有显著抑制效应。在低频情况下与上述相应的目标字表现出不显著的促进和抑制效应。此结果似乎表明汉字词识别过程具有程度不同的语音自动激活效应。     

声旁部分信息在儿童学习和记忆汉字中的作用

采用类似课堂教学的学习－测验任务,通过3个实验探讨了声旁提供的部分读音信息在儿童学习和记忆汉字中的作用。被试来自北京市两所小学260名四年级学生。实验中要求学生学习和记忆3种生字：（1）声旁提供汉字读音的全部信息,如规则一致字;（2）声旁提供汉字读音的部分信息,如声调不同字或声母不同字;（3）声旁不提供汉字读音的信息,如声旁不知字。要求学生学习所有的字一遍后回忆生字的读音,共学习3遍。实验发现,儿童学习和记忆汉字的正确率随声旁提供的整字读音信息不同而不同：当声旁提供全部信息时正确率最高,当声旁提供部分信息时其次,当声旁没有提供信息时最低;而且声旁提供的部分信息越多,正确率越高。结果表明,儿童对声旁提供的部分读音信息敏感,发展声旁意识对学习和记忆汉字有积极作用     

亚词汇水平加工的本质:形旁的语音激活

该研究利用启动命名技术,探讨了汉字加工时是否存在着形旁的语音激活。把含有独立成字的形旁的合体字（如“躲”）作为启动字,与形旁同音的字（如“深”）作为目标字。结果发现,当合体字是低频字时,目标字的命名速度显著加快。高频合体字则没有此效应。集合Ｚｈｏｕ和Ｍａｒｓｌｅｎ－Ｗｉｌｓｏｎ关于声旁语义激活的研究,该文得出结论说,汉字亚同汇水平的加工与词汇水平的加工表现一样,两者之间并无本质性的差别。     

声旁位置对形声字命名规则性效应的影响

已有证据表明, 低频形声字的命名存在规则性效应, 高频字则没有表现。但是, 这些研究所使用的全部或大部分实验材料可能均为声旁在右的字, 其结果也许仅能反映声旁在右字的加工规律。本研究通过三个实验考查了声旁在左与在右两种左右型字和声旁在上与在下两种上下型字的规则性效应, 探讨声旁位置对形声字命名规则性效应的影响。实验一仅考察了声旁在右的字, 结果重复了先前没有操控声旁位置研究中出现的低频字的规则性效应, 还发现高频字命名规则性效应的逆转; 实验二考察了声旁在左与在右的字, 发现声旁在右的低频字存在规则性效应, 而声旁在左的低频字则出现了规则性效应的逆转, 但声旁在右的高频字并不存在逆转; 实验三考察了声旁在上与在下的字, 发现声旁在下的低频字和声旁在上的高、低频字都出现了规则性效应, 而声旁在下的高频字则存在规则性效应的逆转。这些结果提示, 如果声旁在整字中处于易被激活的位置(右侧或下侧), 在低频字中会倾向于出现规则性效应, 在高频字中则可能出现逆转或缺乏规则性效应, 这也许会受到字频的制约; 在低频左右型字中声旁位置的改变也会导致命名规则性效应方向的转变, 但在低频上下型字中的表现要相对较弱。可以推测, 声旁位置是一种形声字的亚词汇成分的空间属性, 可以决定声旁语音激活的便利性; 整字字频则是一种词汇属性, 会通过调节整字的语音激活, 影响声旁语音作用于整字命名的亚词汇加工机制, 最终决定规则性效应的方向。     

Orthographic neighborhood size effect in Chinese character naming: orthographic and phonological activations

The present study examined the effects of orthographic neighborhood (N) size on the cognitive processes underlying Chinese character reading. Previous research has shown increasing N size facilitates word naming and recognition performance in alphabetic languages. Experiment 1 revealed that a large N size was associated with a general inhibition of processes underlying character reading, in contrast to previous findings with alphabetic languages. This inhibitory effect was influenced by regularity and consistency. Experiment 2 sought to assess the effects of higher-frequency neighbors on character naming performance. The results revealed that higher-frequency neighbors with different pronunciation to the target interfered with the phonological retrieval of targets. We propose that this type of interference may have caused the N size effect observed in Experiment 1. The results of Experiment 3 revealed that a large N size facilitated target naming in the absence of higher-frequency neighbors. The current results shed light on the processes underlying character naming, and we propose possible cognitive mechanisms of the N size effect on Chinese character naming.     

汉字正字法家族效应的ERP研究

以汉字为实验材料,自变量为汉字正字法笔画家族大小,采用延迟反应的同一字判断任务,记录并研究大学生被试对刺激字的脑电(EEG)。本文对笔画家族的定义是,通过改变1~5笔笔画得到刺激字的正字法家族成员,改变的笔画不构成部件。脑电结果显示:大家族刺激字比小家族刺激字诱发更负的N400和N250成分、更低的P200,其中N400的结果与基于交互激活模型的二阶段理论的预期一致。     

流动性、教育安置方式和心理弹性对流动儿童孤独感的影响:一项追踪研究

采用潜变量增长模型对426名流动儿童进行四次追踪测查,旨在考察流动儿童孤独感的变化趋势,探索不同流动性和教育安置方式的流动儿童孤独感变化的差异性以及心理弹性对孤独感变化的促进性作用。结果发现：（1）流动儿童的孤独感呈线性下降趋势;（2）打工子弟学校流动儿童的孤独感起始水平显著高于公立学校流动儿童;流动性高的儿童的孤独感起始水平高于流动性低的儿童,但流动性和教育安置方式对孤独感的发展趋势没有显著预测作用;（3）对于流动儿童来说,较高的心理弹性水平不仅能显著预测更低的孤独感起始水平,同时也能显著预测更快的孤独感的下降速率。本研究启示,增加进入公立学校学习的机会、降低流动频率和提升心理弹性对降低流动儿童的孤独感水平具有重要的意义。     

Exploring orthographic neighborhood size effects in a computational model of Chinese character naming

Orthographic neighborhood (N) size effects have been extensively studied in English consistently producing a facilitatory effect in word naming tasks. In contrast, several recent studies on Chinese character naming have demonstrated an inhibitory effect of neighborhood size. Response latencies tend to be inhibited by inconsistent characters with large neighborhoods relative to small neighborhoods. These differences in neighborhood effects between languages may depend on the characteristics (depth) of the mapping between orthography and phonology. To explore this, we first conducted a behavioral experiment to investigate the relationship between neighborhood size, consistency and reading response. The results showed an inhibitory effect of neighborhood size for inconsistent characters but a facilitatory effect for consistent characters. We then developed two computational models based on parallel distributed processing principles to try and capture the nature of the processing that leads to these results in Chinese character naming. Simulations using models based on the triangle model of reading indicated that consistency and neighborhood size interact with the division of labor between semantics and phonology to produce these effects.     

Orthographic neighbors and visual word recognition

Two lexical decision experiments, using words that were selected and closely matched on several criteria associated with lexical access, provide evidence of facilitatory effects of orthographic neighborhood size and no significant evidence of inhibitory effects of orthographic neighborhood frequency on lexical access. The words used in Experiment 1 had few neighbors that were higher in frequency. In Experiment 2, the words employed had several neighbors that were higher in frequency. Both experiments showed that words possessing few neighbors evoked slower responses than those possessing many neighbors. Also, in both experiments, neighborhood size effects occurred even though words from large neighborhoods had more potentially interfering higher-frequency neighbors than words from small neighborhoods.     

两种呈现速度下整字及声旁命名

问题与方法：探讨在快、慢速两种速度呈现条件下,声旁的组字频率和使用频率在整字和部件识别中的作用。结果表明,命名整字时在两种呈现条件下声旁的两类频率都表现在易化作用;命名声旁则依赖于加工时间：快速呈现刺激时声旁组字频率有抑制作用,慢速呈现刺激时声旁使用频率有易化作用。声旁命名任务中,速示条件下其组字频率作用突出,非束示条件下其使用频率更突出。呈现速度在声旁命名时与声旁两类频率有交互作用,但在数字命名时没有。     

Orthographic neighborhood and concreteness effects in the lexical decision task

The experiment reported here investigated the sensitivity of concreteness effects to orthographic neighborhood density and frequency in the visual lexical decision task. The concreteness effect was replicated with a sample of concrete and abstract words that were not matched for orthographic neighborhood features and in which concrete words turned out to have a higher neighborhood density than abstract words. No consistent effect of concreteness was found with a sample of concrete and abstract words matched for orthographic neighborhood density and frequency and having fewer neighbors and higher-frequency neighbors than the words of the first sample. Post hoc analyses of the results showed that orthographic neighborhood density was not a nuisance variable producing a spurious effect of concreteness but, instead, that the existence of higher-frequency neighbors constitutes a necessary condition for concreteness effects to appear in the lexical decision task. This finding is consistent with the hypothesis that semantic information is accessed and used to generate the responses in lexical decision when inhibition from orthographic forms delays the target word recognition.
