This study aimed to investigate the effects of contextual predictability on orthographic and phonological activation during Chinese sentence reading by Cantonese-speaking readers using the error disruption paradigm. Participants' eye fixations and pupil sizes were recorded while they silently read Chinese sentences containing homophonic, orthographic, and unrelated errors. Sentences had varying amounts of contextual information leading up to target words such that some targets were more predictable than others. Results of the fixation time analysis indicated that orthographic effects were significant in first fixation and gaze duration, while phonological effects emerged later in total reading time. However, interactions between predictability and the homophonic condition were found in gaze duration. These results suggest that, while Cantonese readers activate word meanings primarily through orthography in early processing, early phonological activation can occur when facilitated by semantics in high-constraint sentence contexts. Analysis of pupillary response measurements revealed that participants' pupil sizes became larger when they read words containing orthographic errors, suggesting that orthographic error recovery processes significantly increase cognitive load.
本研究旨在使用错误破坏范式，调查语境可预测性对广东话读者在阅读中文句子时的字形和语音激活的影响。参与者在默读包含同音、字形和不相关错误的中文句子时，记录了他们的眼动和瞳孔大小。句子中目标词之前有不同数量的上下文信息，有些目标词比其他目标词更可预测。注视时间分析的结果表明，字形效应在首次注视和注视持续时间上显著，而语音效应在总阅读时间上出现较晚。然而，在注视持续时间上发现了可预测性和同音条件之间的相互作用。这些结果表明，虽然广东话读者在早期处理中主要通过字形激活单词的意思，但在高约束句子语境中语义促进时，早期的语音激活也会发生。瞳孔反应测量的分析表明，当参与者阅读包含字形错误的单词时，他们的瞳孔大小会变大，这表明字形错误恢复过程会显著增加认知负荷。
