摘要

许多研究都试图找出阅读障碍的根源。不同的诵读困难理论提出了语音、注意力或视觉方面的缺陷。虽然已有研究使用眼动追踪技术来研究阅读障碍,但此前只有两项研究使用移动窗口范式来探讨阅读障碍患者阅读时的感知跨度,而没有一项研究在视觉搜索中使用这种范式。本研究利用阅读和视觉搜索任务分析了感知跨度,以确定阅读障碍患者是否存在与语言无关的注意力障碍。我们发现,在阅读障碍中,感知跨度受损的证据不明确,而在视觉搜索中,没有证据表明感知跨度受损。然而,与对照组相比,阅读障碍患者在视觉搜索任务中确实表现出了缺陷,搜索准确率较低,且囊回时间较短。这些结果支持了视觉而非注意或语音对阅读障碍的解释。

The perceptual span in dyslexic reading and visual search

Many studies have attempted to identify the root cause of dyslexia. Different theories of dyslexia have proposed either a phonological, attentional, or visual deficit. While research has used eye-tracking to study dyslexia, only two previous studies have used the moving-window paradigm to explore the perceptual span in dyslexic reading, and none have done so in visual search. The present study analysed the perceptual span using both reading and visual search tasks to identify language-independent attentional impairments in dyslexics. We found equivocal evidence that the perceptual span was impaired in dyslexic reading and no evidence of impairment in visual search. However, dyslexic participants did show deficits in the visual search task, with lower search accuracy and shorter saccades compared with controls. These results lend support for a visual, rather than attentional or phonological, account of dyslexia.

期刊介绍: DYSLEXIA provides reviews and reports of research, assessment and intervention practice. In many fields of enquiry theoretical advances often occur in response to practical needs; and a central aim of the journal is to bring together researchers and practitioners in the field of dyslexia, so that each can learn from the other. Interesting developments, both theoretical and practical, are being reported in many different countries: DYSLEXIA is a forum in which a knowledge of these developments can be shared by readers in all parts of the world.
