单字词和复合词预视加工的差异性研究：词边界信息无影响

本实验采用眼动轨迹记录法并结合边界范式（Rayner, 1975）,操纵单字词和双字复合词的首字为一致预视或假字预视,考察单字词和复合词预视加工的差异性。另外,通过在中文句子中加入词边界信息——词间阴影,以考察词间阴影对单字词和复合词预视加工的影响。实验结果表明,复合词的预视效应大于单字词,并且词间阴影对单字词和复合词的预视加工均没有显著影响。因此,与印欧语系相比,中文阅读中更大更强的预视效应需从更深层次的语言和认知因素进行探讨。该结果更倾向于支持词切分和词汇识别模型。

中文阅读预视加工中的词频和预测性效应及其对词切分的启示:基于眼动的证据

研究采用眼动随动显示技术考察中文阅读预视加工中的词汇加工问题。前三项实验发现,剥夺预视加工的掩蔽条件、正确提示词n+1右侧边界的掩蔽条件以及不能提示词n+1右侧边界的掩蔽条件都不影响词频效应,说明中文读者对词n+1处文字的预视加工达不到词汇水平。实验4考察剥夺预视加工的掩蔽条件、提示词n+1右侧边界的掩蔽条件对预测性效应的影响,结果发现,剥夺预视加工完全消除预测性效应,提示词n+1右侧边界则减少预测性效应,说明对词汇的预期加工是中文读者切分词n+1的参考线索。综合4项实验结果可知,中文读者较难通过自下而上的文字识别切分词n+1,自上而下的词汇预期则是切分词n+1的加工形式。     

汉字位置加工的词边界效应

为探讨汉字位置加工是否存在词边界效应,本研究采用掩蔽启动词汇决定任务和眼动追踪技术,通过2个实验考察了跨词边界和词内汉字转置对词汇识别的影响。实验均以四字词和两个双字词为靶子,对中间两个字进行操纵（转置或保持不变）。结果发现：靶子的注视时间（反应时）在跨词边界转置条件显著长于相同条件,在词内转置条件与相同条件差异不显著。结果表明：跨词边界汉字转置干扰词汇识别,汉字位置加工存在词边界效应。词切分的开始时间可能早于汉字位置加工,或二者是同时发生的。     

阅读中字序编码对自上而下词汇加工的影响

研究采用边界范式通过两项实验考察词内字序编码对预测性效应的影响,结果发现:(1)全程词内字序颠倒和注视中词内字序颠倒都不影响预测性效应,但预视中词内字序颠倒则消除预测性效应,说明预视阶段内词内字序编码影响自上而下词汇加工,却不影响注视阶段内自上而下的词汇加工;(2)预视中词内字序颠倒和注视中词内字序颠倒条件下目标词汇凝视时间都高于全程词内字序颠倒条件,说明整个时程上的词汇加工并不严格依赖于词内字序编码。     

首词素位置概率信息未参与汉语阅读的词切分：基于副中央凹加工的证据

本研究采用边界范式,考察汉语阅读中读者是否在副中央凹处利用首词素的位置概率信息进行词切分和词识别。采用2（首词素位置概率：高、低）×２（预视类型：相同预视、假字预视）的被试内实验设计,以双字词为目标词,记录大学生阅读句子时的眼动轨迹。结果发现,在跳读率和第一遍阅读的眼动指标中,被试在高、低首词素位置概率条件中获得的预视效益量无显著差异。该结果表明,读者并未在副中央凹处加工首词素的位置概率信息。结合前期研究推断,首词素位置概率信息没有作用于汉语阅读的词切分和词识别。     

嵌套词汉字位置加工的亚词边界效应

使用眼动追踪技术，采用边界范式，考察了三字嵌套词的汉字位置加工是否存在亚词边界效应。实验以三字前嵌套词（如“历史系”）和三字后嵌套词（如“核技术”）为靶子，对次字和尾字进行操纵（相同、转置和替换）。结果发现：对于前嵌套词，靶子的注视时间在替换条件显著长于转置条件，相同条件和转置条件差异不显著；对于后嵌套词，靶子的注视时间在转置条件显著长于相同条件，替换条件和转置条件差异不显著。结果表明：跨亚词边界汉字转置不影响词汇识别，而亚词首字转置干扰词汇识别。     

汉字位置加工和词边界效应的认知机制

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。     

汉语阅读中的心理词加工

通过两项研究考察了汉语阅读中心理词存在的心理现实性及其加工效率问题。研究1采用词切分任务考察语法知识掌握水平不同的读者词切分的差异,发现他们在词切分上存在很大分歧,语法知识越丰富,词切分差异越小。研究2探讨心理词的加工效率,使用阴影标记目标词,产生四种呈现条件：正常条件、词汇词条件、心理词条件和非词条件,结果发现心理词比词汇词、非词更容易加工。两项研究结果表明汉语阅读的基本信息单元更可能是心理词。     

中文阅读中的预视效应与词切分*

通过眼动随动显示技术操作注视点右侧文字的掩蔽范围和掩蔽单元,考察中文阅读的预视效应和词切分现象。研究包括两项实验。实验一以词为单元掩蔽注视点右侧的文字,发现词 n 右侧文本掩蔽(条件1)、词n+1右侧文本掩蔽(条件2)和词n+1掩蔽(条件3)均显著影响总阅读时间。其中,条件2剥夺了词n+1以右文字的预视加工,同时提供了词n+1的右侧边界线索,结果导致总阅读时间增加,并减少基于单词的平均凝视时间和再注视概率。实验二采用与实验一相同的处理方式,以不提供词边界的双字为单元掩蔽注视点右侧文字,结果发现掩蔽条件对阅读的影响程度甚于实验一,条件2基于词的平均凝视时间显著高于控制条件。综合两个实验的结果可见,中文读者能够切分出注视点右侧的第一个词汇,并以词为单元识别词n和词n+1处的汉字,在注视词n的时间内可加工到词n+2处的文字。     

学习材料组块方式对相似词长时记忆的影响

已有关于材料相似性影响短时记忆的研究提示, 不相似材料组块相比于相似材料组块可能促进记忆。为验证该假设, 该研究采用学习-测查范式, 通过4个实验考察了学习材料组块方式对相似词长时记忆的影响及机制。结果发现：1)与相似词组块相比, 不相似词组块促进了相似词记忆; 2)不相似词组块的促进效应是通过增强相似词表共同词根的记忆而实现的; 3)不相似词组块的促进效应可能依赖于语音相似性。该结果说明不相似词组块可能是促进相似词汇记忆的有效途径之一。     

情绪词类型效应：区分情绪标签词和情绪负载词的行为和神经活动证据

情绪标签词直接表达情绪状态, 而情绪负载词本身不表达情绪状态, 但能引发个体的情绪反应。通过对情绪标签词和情绪负载词的相关研究综述发现, 情绪标签词与情绪负载词的加工优势存在不一致的结果; 任务需求、语言类型和词汇特征是导致情绪词类型效应不一致的主要原因; 情绪标签词与情绪负载词的加工差异可以通过语义表征的具身假说、密度假说进行解释。未来研究应深入考察情绪标签词与情绪负载词加工差异的原因; 考察两种词在句子和语篇水平的加工差异; 提供能够直接解释情绪词类型效应的理论假说; 对比中英双语者加工中文和英文情绪标签词和情绪负载词的差异; 采用神经成像技术继续探查情绪信息与语义信息加工的神经机制。     

Producing and recognizing words with two pronunciation variants: Evidence from novel schwa words

This study examined the lexical representations and psycholinguistic mechanisms underlying the production and recognition of novel words with two pronunciation variants in French. Participants first learned novel schwa words (e.g., /??nyk/), which varied in their alternating status (i.e., whether these words were learned with one or two variants) and, for alternating words, in the frequency of their variants. They were then tested in picture-naming (free or induced) and recognition memory tasks (i.e., deciding whether spoken items were learned during the experiment or not). Results for free naming show an influence of variant frequency on responses, more frequent variants being produced more often. Moreover, our data show an effect of the alternating status of the novel words on naming latencies, with longer latencies for alternating than for nonalternating novel words. These induced naming results suggest that both variants are stored as lexical entries and compete during the lexeme selection process. Results for recognition show an effect of variant frequency on reaction times and no effect of variant type (i.e., schwa versus reduced variant). Taken together, our findings suggest that participants both comprehend and produce novel French schwa words using two lexical representations, one for each variant.     

词边界信息对读者阅读歧义短语时眼跳策略的影响

采用Eye Link 2000眼动仪,选取60个歧义短语,要求大学生被试阅读包含有歧义短语的句子。句子的呈现设置了四种条件:正常无阴影、词间阴影、歧义阴影和字间阴影,以探讨词边界信息是否影响读者阅读歧义短语时的注视位置效应。结果发现:读者对歧义短语的首次注视位置在四种条件下基本一致;词边界信息影响读者对歧义短语的再注视概率。结果表明,词边界信息对歧义短语的影响主要体现在眼跳行动(即"where")的晚期阶段。     

Affective picture processing is modulated by emotion word type in masked priming paradigm: an event-related potential study

ABSTRACT

Although a large body of research demonstrates the role of language in emotion processing (e.g. emotional facial expressions), how emotion-laden words (e.g. poison, reward) and emotion-label words (e.g. fear, satisfaction) differently impact affective picture processing is not clear. Emotion-label words label affective states straightforwardly, whereas emotion-laden words engender emotion via reflection. The current study adopted the masked priming paradigm to examine how Chinese emotion-laden words and emotion-label words distinctively influence affective picture processing. Twenty Chinese speakers decided the valence of the pictures with their cortical responses recorded. Emotion-label words facilitated affective picture evaluation behaviourally. Moreover, pictures that were preceded by emotion-laden words generated larger electrophysiological activation than those preceded by emotion-label words. Combined behavioural and ERP evidence revealed that emotion word type modulated affective picture processing, suggesting different roles of emotion-laden and emotion-label words in how emotion is shaped by language.     

A word about words

The title of my paper comes from an essay by Václav Havel. In his essay, Havel addressed most evocatively the question of the unique power of words for thinking and to influence, for good or for harm, as well as to inform and to educate. As analysts our medium is the word. I suggest that it is of inestimable importance that we are able to listen deeply to our patients' words and to be aware of our own. The quality of our ability to think deeply and consistently about the unconscious experience of our patient is intimately related to our ability to hear what is being said. The effect of our own words upon the patient likewise cannot be overstated. I offer my reflections on words in the analytic relationship and I give some clinical examples that I hope will illustrate my thoughts as to the power and the importance of what and how we hear and of what we say.     

Parafoveal processing within and between words

Parafoveal preview was examined within and between words in two eye movement experiments. In Experiment 1, unspaced and spaced English compound words were used (e.g., basketball, tennis ball). Prior to fixating the second lexeme, either a correct or a partial parafoveal preview (e.g., ball or badk) was provided using the boundary paradigm (Rayner, 1975). There was a larger effect of parafoveal preview on unspaced compound words than on spaced compound words. However, the parafoveal preview effect on spaced compound words was larger than would be predicted on the basis of prior research. Experiment 2 examined whether this large effect was due to spaced compounds forming a larger linguistic unit by pairing spaced compounds with nonlexicalized adjective–noun pairs. There were no significant interactions between item type and parafoveal preview, suggesting that it is the syntactic predictability of the noun that is driving the large preview effect.     

《庄子》哲学中的名与言

The examination of names and words constitutes an important aspect of the philosophy of Zhuangzi. With the debate over the relationship between name and reality as its background, this examination not only involves the connection between form and meaning, but also targets at the connection between concepts and objects. The debate over the relationship between name and reality correlates with the discussion of the connection between words and meanings or ideas. For Zhuangzi, the function of names and words is first and foremost embodied as the classification and distinction of being, while the Dao, as the universal principle of being, is characterized by equality and throughness. This leads to an inherent disparity and tension between names, words and the Dao. Zhuangzi℉s thinking and argument concern the connections between name and reality, words and ideas, and the Dao and words. This displays multiple theoretical perspectives and the complexity of its thought. Translated by Xiao Mo from Zhongguo Shehui Kexue 中国社会科学(Social Sciences in China), 2006, (4): 38–49     

中心词和非中心词在句法启动的词汇增强效应中存在不同的机制

句法启动中, 非中心词和中心词重复是否诱发出相似强度的词汇增强效应, 目前存在着较大的理论争议。本研究在汉语双宾结构和介宾结构上分别操纵中心词和非中心词重复, 并在确保具有合适统计检验力基础上, 完成了3个句法启动实验。实验结果清楚地显示中心词重复诱发了稳定的词汇增强效应, 非中心词中的直接宾语重复也诱发了稳定但相对较弱的词汇增强效应。在此基础上, 我们尝试提出一个解释框架以调和现有的理论争议。
