快速自动命名对阅读的影响及其作用机制

The influence of rapid automatized naming on reading and its mechanism

快速自动命名(Rapid Automatized Naming,RAN)如何影响阅读尚存争议。有研究表明个体单个单词加工效率主导了RAN对阅读的影响。另有研究发现单个单词加工效率和连续加工效率共同作用的“级联”加工过程才是主导RAN影响阅读的主要因素。这与个体视觉注意广度(VAS)起到的调节作用有关。低VAS读者识别正字法单位数量有限,他们在连续阅读时以离散的形式逐个阅读单个单词,单个单词加工效率主导RAN和阅读的关系;高VAS读者将单词视为一个整体,在多个词之间进行连续的并列加工,这种“级联”的加工过程主导了RAN与阅读的关系。未来研究应关注阅读过程中个体的VAS差异,增加阅读材料的复杂性和正字法的不一致性,进一步探究RAN与阅读的关系以及不同水平VAS对它的影响,丰富发展性阅读障碍患者的非语言干预措施相关理论。

How does Rapid Automatized Naming(RAN)affects reading is still controversial.Studies have shown that individual word processing efficiency dominated the effect of RAN on reading.However,another study found that the“cascading”processing process,which combined single word processing efficiency and serial processing efficiency,was the main factor that dominated RAN's influence on reading.This is related to the effect of visual attention span(VAS).Low VAS readers recognized a limited number of orthographic units,and they read individual words one by one when they read.The relationship between RAN and reading was dominated by the efficiency of single word processing.High VAS readers treat words as a whole unit and process them in parallel among multiple words.This“cascade”of processing dominates the relationship between RAN and reading.The studies in future should focus on individual differences in VAS during reading,increase the complexity of reading materials and orthographic inconsistencies,further explore the relationship between RAN and reading,also pay attention to the influence of VAS at different levels on it,and enrich the theories related to nonverbal interventions for developmental dyslexia.
