| Summary: | 碩士 === 國立臺北護理健康大學 === 聽語障礙科學研究所 === 99 === This purpose of the present study was to investigate the effect of frequency, consistency, regularity and pseudocharacter on the naming of Chinese characters in alexic patients. 22 Chinese alexic patients and 22 age and education matched normal readers participated in this study. The materials contained Chinese characters of high/low frequency, consistency, regularity and also pseudocharactera in both groups of subjects. Result of this study showed that frequency is a robust factor on both reaction time and accuracy of character naming in both groups. Consistency and regularity effect was shown in both reaction time and accuracy in the normal subjects but only for the low frequency characters. Consistency and regularity effect was noted too in the alexic group, but only in reading accuracy, both in high and low frequency characters. The successful rate of reading pseudocharacters was also affected by the phonetic consistency in both groups.
In both groups, there were many tone errors, phonemic errors and neighborhood substitutions. The error pattern of normal readers was more centralized, but it was more dispersed in alexic patients. These results suggest that alexic patients, like normal subjects, tend to be affected by phonological rules upon reading aloud Chinese characters, but more loosely.
