在关于阅读过程中眼动控制的研究中，与语言理解相关的认知过程相对于眼跳产生的视觉方面的重要性是一个持续争论的话题。在这里，我们调查各种眼动措施在阅读随机洗牌无意义的文本相比，正常的有意义的文本。为了确保材料的处理，读者偶尔会被探测正常或混洗文本中出现的单词。对于阅读混洗文本，我们观察到更长的固定时间，较少的单词跳跃，和更多的再固定比正常阅读。混洗文本阅读与正常阅读的进一步不同之处在于，低频词的整体固定时间并不比高频词长。然而，频率的影响是存在于长的话，但被逆转的短的话。此外，与我们之前的研究一致，我们发现了不同的实验效果的空间分布处理在几个单词的时间，表明词汇的文字处理影响眼球运动。基于统计线性混合效应模型的分析，我们认为，这一结果是兼容的假设，即中心凹负荷更强烈的调制在洗牌阅读任务比在正常的阅读。结果进行了讨论的背景下，计算模型的阅读。
In research on eye-movement control during reading, the importance of cognitive processes related to language comprehension relative to visuomotor aspects of saccade generation is the topic of an ongoing debate. Here we investigate various eye-movement measures during reading of randomly shuffled meaningless text as compared to normal meaningful text. To ensure processing of the material, readers were occasionally probed for words occurring in normal or shuffled text. For reading of shuffled text we observed longer fixation times, less word skippings, and more refixations than in normal reading. Shuffled-text reading further differed from normal reading in that low-frequency words were not overall fixated longer than high-frequency words. However, the frequency effect was present on long words, but was reversed for short words. Also, consistent with our prior research we found distinct experimental effects of spatially distributed processing over several words at a time, indicating how lexical word processing affected eye movements. Based on analyses of statistical linear mixed-effect models we argue that the results are compatible with the hypothesis that the perceptual span is more strongly modulated by foveal load in the shuffled reading task than in normal reading. Results are discussed in the context of computational models of reading.
