摘要
为深入研究汉字图像模式识别的早期知觉过程 ,以 6、9、12画高、低字频宋体汉字为材料 ,在 4种空间频率条件下做视觉辨别实验 ,结果再现了空间频率效应、笔画数效应和字频效应。作者分析认为 :(1)汉字识别是在图像相似性判断基础上进行和完成的 ,表现为同样的线性过程 ;只是由于知觉辨别的零起点不同 ,才显示出笔画数效应 ;(2 )字频效应在阈限识别水平之后开始出现 ;(3)汉字识别早期知觉过程先后经历了异形区分 (属间判别 )、同形辨认 (属内判别 )
Infrequent and frequent Chinese characters of 6, 9, or 12 strokes in song font were used in an identification task experiment to investigate the early perception process of Chinese character recognition,under 0~1.5, 0~2.0, 0~2.5 and 0~3.0cpd spatial frequency conditions. The effects of spatial frequency content, strokes and word frequencies of Chinese characters were revealed.The author concluded that the early perception of Chinese character identification seemed to share a linear process based on similarity judgment and matching of visual\|spatial information , and the stroke effect seemed to be derived from different Euclidean distances at which the 6, 9, and 12 strokes were first identified.It was discovered that discrimination between\|categories and checking within\|categories were experienced in early perception of word recognition.
