Three experiments examine the role of previously read text in sentence comprehension and the control of eye movements during spontaneous rereading. Spontaneous rereading begins with a regressive saccade and involves reinspection of previously read text. All 3 experiments employed the gaze-contingent change technique to modulate the availability of previously read text. In Experiment 1, previously read text was permanently masked either immediately to the left of the fixated word (beyond word) or more than 1 word to the left (beyond word). The results of Experiment 1 indicate that the availability of the word immediately to the left (word) is important for comprehension. Experiments 2 and 3 further explored the role of previously read text beyond word. In these studies, text beyond wordn-1 was replaced, retaining only word length information, or word length and shape information. Following a regression back within a sentence, meaningful text either reappeared or remained unavailable during rereading. The experiments show that the visual format of text beyond word (the parafoveal postview) is important for triggering regressions. The results also indicate that, as least for more complex sentences, the availability of meaningful text is important in driving eye movement control during rereading. (PsycINFO Database Record
三项实验考察了先前阅读的文本在句子理解以及自发重读过程中眼动控制方面的作用。自发重读始于一个回退扫视，并涉及对先前阅读文本的重新审视。所有三项实验都采用了注视点相关变化技术来调节先前阅读文本的可获取性。在实验1中，先前阅读的文本要么在注视单词左侧紧邻位置（超出单词范围），要么在左侧超过一个单词的位置（超出单词范围）被永久性遮挡。实验1的结果表明，紧邻左侧单词（单词范围）的可获取性对理解很重要。实验2和3进一步探究了超出单词范围的先前阅读文本的作用。在这些研究中，超出单词n - 1范围的文本被替换，仅保留单词长度信息，或者单词长度和形状信息。在句子中回退之后，重读期间有意义的文本要么重新出现，要么仍然无法获取。实验表明，超出单词范围的文本的视觉形式（副中央凹后视图）对于触发回退很重要。结果还表明，至少对于更复杂的句子，有意义文本的可获取性在重读期间驱动眼动控制方面很重要。（《心理学文摘数据库记录》
