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。     

云南4个民族20年跨文化心理研究——议青少年品格的发展

调查者于1980年惊奇地发现西双版纳的克木人、基诺族、哈尼族和拉祜族的青少年品德与个性非常良好,调查者关注的是在现代化的影响下,这些品德个性的变化。这项研究的目的是探索青少年品德与个性发展的规律,同时,这对跨文化心理的研究也有重要意义。研究采用不同的研究方法,如访谈、个别接触、活动分析,甚至为了调查而几个月与青少年住在一起。2002年,研究表明,青少年的品德与个性已有很大变化,他们积极、自信、乐观和有竞争意识,他们的品格至今仍保持良好,犯罪率低,民族青少年的社会化在这变化与发展中起重要作用。     

地震经历对插入空白间隔的汉字知觉干扰效应的影响

以插入空白间隔的汉字知觉干扰效应为实验范式, 探讨了不同长短的空白间隔对地震相关字和无关字的影响。结果发现：(1)在实验组中, 与地震无关字相比, 被试对地震相关字有更高的识别率; 而在对照组中, 被试对地震相关字和无关字的识别率差异不显著。(2) 450 ms的间隔能导致地震无关字干扰效应的消失, 却不会对地震相关字的识别造成干扰。本研究支持竞争激活假说, 并为情绪驱动知觉加工的观点提供证据。     

声旁规则性对命名声旁和整字的影响

探讨声旁规则性对命名声旁或整字的影响,在速示与慢示呈现条件下命名声旁或汉字。结果发现：（1）声旁命名在速示呈现时因规则声旁易化;慢示呈现时无显著规则性效应,但受声旁部件数影响;（2）在两种呈现条件下,命名含不表音声旁字的反应时最快,错误率最低;命名含单部件、高频声旁字的反应时慢,错误率高;命名含多部件、低频声旁字的反应时快,错误率低。说明是声旁规则性对声旁命名有易化作用;对整字命名有干扰作用,但与声旁频率与部件数有关。     

整字、部件与笔画对笔画构成汉字的影响

该研究采用笔画构成汉字的实验范式,利用整字、部件、笔画作为启动材料考查了笔画构成汉字过程中整体与部分之间的关系。实验中要求被试用给出的笔画组（四划或五划）构成汉字,并且判断笔画组是否能够构成一个真实的汉字。结果发现整字在笔画构成汉字的实验过程中起到最为关键的作用。其次是笔画存在着明显的启动效应,部件的启动效应最弱。结论：在笔画构成汉字的过程中,主要以整字加工为主,笔画加工也起到了重要作用。     

视角对高频汉字识别的影响

用EyeLinkII型眼动仪为实验设备 ,以汉字与双眼形成的视角为自变量 ,研究了视角对高频汉字识别的影响特点。本实验中的视角分为 7个水平 :2°、4°、7°、1 0°、1 3°、1 6°、1 9° ,通过自编程序 ,计算出固定距离条件中不同视角下汉字的大小 ,呈现在计算机屏幕上 ,要求被试发声识别汉字。通过对反应时、注视时间、注视次数、眼跳时间、眼跳次数、眨眼时间、眨眼次数的分析。结果发现 :不同视角条件下的反应时总体差异不显著 ,反应时随视角的变化曲线为抛物线 ,开口向上 ;汉字识别的最适宜视角为 1 0°～ 1 1°。     

Perceiving a part and the whole of narrative scenes with interactive processing between character and surroundings

Visual recognition is a fast and accurate process. This study adopted a progressive revelation task which demonstrated the dynamic visual process to investigate narrative scene perception. Experiment 1 examined the recognition of character and surroundings that are presented in isolation. The results demonstrated an accumulation of perceptual evidence for recognition as a psychometric function, and character identification was found to be superior to surroundings identification (character advantage effect). Experiment 2 examined the character and surroundings identification in isolated and concurrent presentations. The results showed that less accumulated evidence was required for the concurrent condition than for the isolated condition in the surroundings identification but not in the character identification. The character advantage effect only appeared in the isolated condition. In Experiment 3, both the character and surroundings in semantically consistent or inconsistent scenes were reported. The results showed that consistency effects appeared in both character and surroundings reporting, and the character advantage effect appeared in both consistent and inconsistent conditions. Overall, the results of the present study, which have high ecological validity, supported the existence of an interactive relationship between the visual processing of character and surroundings in narrative scene perception.     

Brain networks associated with sublexical properties of Chinese characters

Cognitive models of reading all assume some division of labor among processing pathways in mapping among print, sound and meaning. Many studies of the neural basis of reading have used task manipulations such as rhyme or synonym judgment to tap these processes independently. Here we take advantage of specific properties of the Chinese writing system to test how differential availability of sublexical information about sound and meaning, as well as the orthographic structure of characters, pseudo-characters and “artificial” control stimuli influence brain activation in the context of the same one-back task. Analyses combine a data-driven approach that identifies temporally coherent patterns of activity over the course of the entire experiment with hypothesis-testing based on the correlation of these patterns with predictors for different stimulus classes. The results reveal a large network of task-related activity. Both the extent of this network and activity in regions commonly observed in studies of Chinese reading are apparently related to task difficulty. Other regions, including temporo-parietal cortex, were sensitive to particular sublexical functional units in mapping among print, sound, and meaning.     

A Functional Analysis of 2004 Ukrainian Presidential Debates

Political leaders’ debates are an important and highly visible instances of public argumentation. As such, they merit scholarly attention. This essay applies the Functional Theory of Political Campaign Discourse to analyze televised presidential debates from the Ukraine in 2004. Overall, this analysis revealed that acclaims were the most common function, followed by attacks and then defenses. Policy was addressed more often than character in these debates, as expected. The incumbent candidate acclaimed significantly more and attacked less than the challenger. The incumbents used past deeds significantly more often to acclaim – and less to attack – than the challengers. Finally, general goals and ideals were used more as the basis for acclaims than attacks in these debates. Implications of these results are discussed.
