结构对称汉字识别的加工机制(I)——整字识别的实验研究

在前期关于整字识别研究的基础上 ,增加任务难度 ,以不同倾斜角度呈现汉字、在心理旋转条件下进一步考察了结构对称汉字识别的加工机制。结果表明 :结构对称字的反应时随着识别难度增加而延长的幅度明显小于非对称汉字 ,而且 ,在刺激字的各种倾斜状态下 ,结构对称汉字的识别反应时均显著小于非对称汉字 ,说明汉字的结构对称性不仅可促进汉字的识别进程 ,而且可增强汉字识别的恒常性。

THE PROCESSING OF STRUCTURALLY SYMMETRICAL CHINESE CHARACTER RECOGNITION (I) : AN EXPERIMENTAL RESEARCH ON CHARECTER LEVEL PROCESS

Based on previous researches, under changed background condition and with increased task difficulty of Chinese character recognition, this experiment was made by means of naming tasks to further observe the structurally symmetrical effects on the character level process and its influence on perceptual constancy in Chinese character recognition under mental rotation. The results indicated that the reaction time of structurally symmetrical Chinese character recognition was significantly shorter than that of asymmetrical Chinese character recognition under the tilted condition , and the delay of reaction time of structurally symmetrical Chinese characters with task difficulty increasing was significantly less than that of asymmetrical Chinese characters. This meant that structural symmetry could enhance the perceptual constancy and speed processing of Chinese character recognition in the mental rotation condition.
