21名有阅读障碍的读者和21名年轻的无阅读障碍的读者在朗读2篇课文时的眼睛注视模式进行了比较。该研究考察了之前在熟练的成人阅读者中发现的词频和词长效应是否同样适用于年轻的阅读障碍者和非阅读障碍者。低频率和长的单词比高频率和短的单词的注视时间和复检时间显着更长。这些影响也表现在对目标词的注视次数上。两个实验组的效果没有显著差异。这一结果与阅读障碍的眼功能障碍假说背道而驰。相反，他们支持这样的观点，即有阅读障碍和无阅读障碍的读者的眼睛注视模式反映了他们在成功识别文本中的单词时的困难。
Eye fixation patterns of 21 dyslexic and 21 younger, nondyslexic readers were compared when they read aloud 2 texts. The study examined whether word-frequency and word-length effects previously found for skilled adult readers would generalize equally to younger dyslexic and nondyslexic readers. Significantly longer gaze durations and reinspection times were found for low-frequency and long words than for high-frequency and short words. The effects also showed up in the number of fixations on the target words. The effects did not differ significantly for the 2 experimental groups. The results run counter to the oculomotor dysfunction hypothesis of dyslexia. Instead, they support the view that both dyslexic and nondyslexic readers' eye fixation patterns reflect their difficulties in successfully identifying words in a text.
