Is Radical-by-Radical Reading Strategy Effective for Chinese Pure Alexia? A Case Study

摘要

Objective: Currently, it is unclear whether a radical-by-radical (RBR) reading strategy exists in Chinese pure alexia, compared to the letter-by-letter (LBL) reading strategy in alphabetic languages. In this study, we focus on exploring the reading features of a Chinese pure alexic patient during the process of language recovery. Method: We investigated this issue using a series of neuropsychological tests at 4 days, 11 days, and 8 months after admission of a Chinese pure alexic patient. Results: The results showed that most words could not be read aloud initially by the patient. One week later, 2 clinical features were noted: RBR reading strategy and integration impairment. Finally, there were statistically significant differences in the reaction time between the single characters and compound characters, which indicated that a radical number effect may exist. Conclusion: Combined with the results of previous studies, the current case study indicates that there is evidence suggesting that the RBR reading strategy in Chinese pure alexia is of limited benefit, a result that appears fundamentally different from the LBL reading strategy.
