空格在文本阅读中的作用

本文总结空格在文本阅读中作用的相关研究, 主要包括以下内容: (1)删除或替代有空格文本中的空格, 对阅读产生的干扰作用; (2)在无空格的文本中插入空格, 对阅读产生一定的促进作用, 空格在汉语阅读中的作用受被试阅读经验、阅读方式和空格大小等因素影响; (3)被试母语和第二语言呈现方式的一致性会影响空格在第二语言阅读中的作用; (4)今后应结合眼动控制理论, 从注视点落点位置和熟悉性等方面开展研究。     

汉语词汇产生中语义、字形和音韵激活的时间进程

通过图画－词汇干扰实验范式探索汉语单字词产生中语义、字形和语音激活的时间进程。实验一和实验二的结果综合表明：当SOA为-300 ms~0 ms时,存在语义抑制效应,当SOA为-100 ms~100 ms时,存在字形促进效应,当SOA为100 ms时,存在语音促进效应。实验结果支持交互激活理论的观点。实验成功地分离了字形促进效应和语音促进效应,确定了语义、字形和语音这三种信息在汉语口语词汇产生中通达的先后次序,讨论了字形信息在词汇产生中的重要作用,以及被试是否在实验中使用了策略。     

汉语口语句子产生的语法编码计划单元

语法编码的计划单元作为口语句子产生领域的一个重要命题,近年来备受心理语言学者的关注。本研究利用词图干扰范式下的语义效应,通过两个行为实验探讨了汉语口语句子产生中的语法编码计划单元。实验中要求被试用介词短语做主语的句子或者并列名词短语做主语的句子来命名两个竖直排列的图片,并视觉呈现干扰词。结果表明,对于两个句式而言,在第二个名词上都没有潜伏期的语义干扰效应,只有错误率上的语义干扰效应,而且这个结果并没有随着SOA(目标图片和干扰词开始呈现的时间间隔)的改变(0、150或300ms)而改变。当干扰词与图片同时呈现时(SOA=0)在并列名词短语做主语的句子中,第二个名词上出现了潜伏期的语义促进效应。这些结果说明,语法编码的说法较为宽泛,应具体描述为:词汇选择是严格递进的,而概念激活的计划单元可能是功能短语。     

Lexical status of inflectional and derivational suffixes: Evidence from Finnish

The present study tested whether Finnish inflectional or derivational suffixes have lexical access units separate from word roots. In three lexical decision experiments, pseudowords carrying a case-inflection required significantly longer rejection times than nonaffixed pseudowords. This suggests that case-inflections have separate lexical access units. Similar effects were obtained for productive derivational suffixes, too. A specific lexical architecture, being able to account for both the present pseudoword results as well as earlier ones obtained with real Finnish nouns, is proposed.     

Activation of emotion information in text among younger and older adults

The ability to represent emotions is an important capacity for the understanding of discourse. In the current literature, it is unclear whether older adults represent emotion information in the course of language processing, in particular as it relates to developing an adequate mental model of characters in narratives. We addressed this issue in two studies, one assessing emotion activation at the word level and the other at the mental model level. In the first experiment, subjects performed a lexical decision task in which words were drawn from both logic- and emotion-based categories. For both category types, priming was evident for young and old. In the second experiment, subjects read passages with emotion information that was consistent or inconsistent with the implied emotional tone. Both age groups showed an increase in reading time in response to inconsistent emotion information, indicating that the protagonist's emotional state was represented while reading. Results of these studies generally suggest age preservation in the activation of emotion information in language processing.     

Some linguistic determinants of Swedish word recognition

Native Swedish words and words of foreign origin were studied in a word fill-in task (Experiment 1), in a task in which words were explicitly classified as being native or loan words (Experiment 2), and in a lexical decision task in which a small onset asynchrony was introduced in displaying a word's letter pattern (Experiment 3). The findings obtained show that, both in simple printed word recognition and when asked to make explicit judgments about origin, readers are sensitive to phonological features of words not marked in Swedish orthography. It was further found that previewing a substring of word-initial letters which determines a word's root morpheme will prime recognition, whereas previewing a randomly selected pattern of letters inhibits recognition.     

Compositionality and the Prospect of a Pluralistic Semantic Theory

A semantic theory is committed to semantic monism just in case every particular semantic property posited by the theory is a member of the same kind. The commitment to semantic monism appears to draw some support from the need to provide a compositional semantics, since taking a single kind of semantic property as key to a semantic theory affords a uniform pattern on the basis of which the meaning of any given sentence can be compositionally determined. This line of support highlights a tension between the principle of compositionality and taking a more pluralistic approach to semantic theorizing. In this essay, that tension is relieved, leaving open the prospect of a pluralistic semantic theory that observes the principle of compositionality.     

延迟命名任务中图词干扰效应的眼动研究

采用图-词分离呈现及眼动技术探讨在延时命名条件下图-词干扰效应发生的位置。结果发现：（1）延时命名图片时,仍出现图-词干扰效应和频率效应;（2）与命名干扰词相比,命名图片时图片的回视率高,注视时间长;（3）图片的注视时间也出现频率效应和图-词干扰效应。这说明即使在延时命名图片的条件下,目标词汇仍需要再次激活,频率效应和图-词干扰效应是发生在词汇化过程中,反驳反应排除理论的图-词干扰反应选择阶段的观点,支持了词汇化选择竞争的理论。     

汉语句子加工中句法信息与语义信息的交互作用：来自ERP的证据

采用ERP技术考察句子加工过程中句法信息和语义信息交互作用的时间进程。以汉语“把字句”为实验材料,分别比较句法违例句与双重违例句的LAN和P600效应、语义违例句与双重违例句的N400效应。与句法违例句相比,双重违例句的LAN效应的波幅更负,潜伏期更长,皮层分布更广泛;双重违例句的P600效应出现减弱趋势;双重违例句的N400效应的潜伏期显著长于语义违例句。结果表明,在句子加工的各个阶段,句法信息和语义信息呈持续交互作用,支持句子的平行加工模型。     

短期习得的语言范畴使成人大脑右半球颜色范畴知觉转为左半球颜色范畴知觉

本研究探讨了色词与颜色重组训练能否让被试习得与真实情境相似的色词与颜色范畴联结, 并引起相应的偏侧化颜色范畴知觉, 从而进一步揭示语言编码对颜色范畴知觉的影响。采用六种蓝色作为材料。B1与B2为先前研究的两种蓝色。B11和B12, B21和B22分别为使B1, B2变浅和变深所得, 四者是连续的蓝色。训练被试分别用“duān”和“kěn”命名B1和B2。由于被试可能习得色词与颜色范畴的联结, 因此B12与B21为可能变范畴间颜色, B11和B12, B21和B22为可能变范畴内颜色。训练前后分别让被试完成一个视觉搜索测验。结果发现：前测中可能变范畴间颜色的辨别优于可能变范畴内颜色, 且在左视野呈现时更显著; 后测中可能变范畴间颜色的辨别同样优于可能变范畴内颜色, 但在右视野呈现时更显著。这提示：(1)人们在知觉同一语言范畴的不同颜色时可能会区分深浅范畴, 并因此引发右半球颜色范畴知觉; (2)短期习得的语言范畴能引起偏左半球颜色范畴知觉, 且使右半球颜色范畴知觉转为左半球颜色范畴知觉; (3)被试在训练中习得了色词与颜色范畴的联结; (4)范畴学习可以在仅学习一个样例的条件下自动发生。
