Developmental dyslexia is a specific reading disability characterized by decoding and spelling deficits that continue into adulthood. Because reading involves both attentional functions and audiovisual (AV) processing, the aim of this study was to explore the associations between the two factors in adult dyslexic readers. Adult non‐impaired and dyslexic readers undertook alphabetic and non‐alphabetic tasks, each composed of three experimental blocks. Two experimental blocks contained left and right spatial selective attention manipulations, and another block included central presentations of the stimuli. Event‐related potential (ERP) and behavioural parameters were collected and analysed, particularly with respect to the N1‐P2 ERP complex. The dyslexic readers showed deviant patterns of amplitudes when it came to alphabetic stimuli processing. However, there was no difference between the two groups with regard to the non‐alphabetic stimuli. These results imply that adult dyslexic readers allocate altered attentional resources when it comes to the processing of AV alphabetic stimuli.

成人阅读障碍者的视听处理和选择性注意：一项与事件相关的潜在研究

发展性阅读障碍是一种特殊的阅读障碍，其特征是解码和拼写缺陷持续到成年。因为阅读涉及注意力功能和视听（AV）处理，所以本研究的目的是探讨成人阅读障碍读者中两个因素之间的关联。成人无障碍和阅读障碍的读者承担了字母和非字母的任务，每个任务都由三个实验模块组成。两个实验块包含左右空间选择性注意操纵，另一个块包含刺激的中央提示。收集并分析了与事件相关的电位（ERP）和行为参数，特别是针对N1-P2 ERP复合物。阅读困难的读者在进行字母刺激处理时表现出幅度的异常模式。但是，两组之间在非字母刺激方面没有差异。这些结果表明，成人阅读障碍读者在处理AV字母刺激时会分配改变的注意力资源。
