合体汉字字形识别过程探索

该研究用微观发生范式探索了合体汉字和假字的字形识别过程 ,结果发现 :(1 )部件字、真字和假字的正确提取率随呈现时间增长而提高 ,字形刺激的特征加工是一个有序的发展过程 ,对字形的识别加工过程受字形熟悉性和字形结构方式的影响 ;(2 )在左右型字刺激和上下型字刺激中 ,经常首先从右部件或下部件中提取笔画或笔画组合 (称首特征 ) ,而且首特征的提取不受字形熟悉性影响。根据以上结果可以推测 ,字形结构属性在字形识别加工的最初阶段先于特征获加工 ,字形熟悉性则对首特征提取后的特征或部件加工过程产生影响。

A Study on the Cognitive Process of Identification of Two-Radical Chinese Characters

It is an attractive topic to illustrate the global and local feature in perceptual processing of word .The present study was designed using a microgenetic paradigm to explore detection of feature, radicals, and character in the identification of two radical Chinese Characters. The experiment used 48 real characters, 48 pseudo characters and 88 radicals as stimuli. Thirty eight paid undergraduate students (19 males, 19 females) participated in the experiment. In each trial the subject was asked to write down what he/she observed immediately after a character was presented tachistoscopically. Exposure time of character took 9 steps progressively: 13ms, 19ms, 25ms, 31ms, 40ms, 50ms, 70ms, 100ms and 150ms. The results are as follows: (1) The accuracy in identifying real characters, pseudo characters and radicals is improved as the result of increase of character exposure. The process of feature extraction, therefore, develops step by step and is affected by character familiarity and character configuration. (2) It seems that the first extracted feature is usually from the right radical of right left structure character, and the lower radical of upper lower structure character. No effect of the character familiarity is found on extraction of the first feature. Therefore, it can be concluded that the processing of character configuration is proceed feature analysis.
