Abstract: Rapid automatized naming (RAN) deficit is a dominant deficit of Chinese developmental dyslexic(DD). Two hypotheses have been put forward to account for the RAN dysfunction in dyslexic: parafoveal processing difficulty and foveal-parafoveal difficulty. In Experiment 1, the boundary paradigm was used in discrete RAN to investigate whether Chinese dyslexic had parafoveal processing deficit in discrete RAN while participants' eye movements were recorded. Three groups of children were selected as participants, i.e., children with DD, chronological age-matched children (CA), and reading level-matched children (RL). In Experiment 1, preview time and the type of preview were manipulated. The results showed that there was no evidence demonstrating that Chinese children with DD had parafoveal processing difficulty in RAN task. In Experiment 2, the boundary paradigm was used in serial RAN such that the preview information was presented firstly and target characters appeared only when the foveal processing started. We found significant phonological and orthographical priming effects for all three groups of child participants. Children with DD had clear RAN deficit with larger preview effects. Taken together, we argue that the RAN deficit of DD is caused by their foveal-parafoveal difficulty.

摘要: 汉语发展性阅读障碍(DD)儿童在快速命名(RAN)任务中会表现出显著缺陷,从眼动加工的视角,其成因主要存在两种观点,即副中央凹加工困难和中央凹-副中央凹困难。本研究运用眼动追踪技术,实验1将边界范式与单项RAN结合,操纵预视时间和预视类型,探究汉语DD儿童在单项RAN中的副中央凹预视效应,结果并未发现汉语DD儿童表现出副中央凹加工困难。实验2将边界范式与系列RAN结合,对预视类型进行操纵,探究汉语DD儿童在系列RAN中的副中央凹预视效应,结果表明汉语DD儿童与正常儿童的副中央凹预视效应存在差异,同时表现出显著的RAN缺陷。这证明了汉语DD儿童的RAN缺陷由中央凹与副中央凹共同作用导致。
