本文中的实验扩展了 A. W. Inhoff 和 K. Rayner (1986) 以及 J. M. Henderson 和 F. Ferreira (1990) 的研究，以确定两个相邻单词的打印频率如何影响第二个单词的旁中心预览的好处。 对高跨度和低跨度参与者（由 M. Daneman 和 P. A. Carpenter's，1980 年阅读跨度测试进行评估）进行了测试，以确定工作记忆容量是否影响中心凹预览益处。 中心凹预览的益处是由第一次注视中两个单词的频率和凝视持续时间中第二个单词的频率的相互作用决定的。 然而，当第一个单词出现频率较低时，读者通常会关注第二个单词的开头。 当观看距离混淆最小化时，先前单词的频率确实会影响中心凹预览效果。 中心凹预览的益处在阅读组之间没有差异。 固视持续时间的群体分布没有为 J. M. Henderson 和 F. Ferreira 的固视截止模型提供证据。
The experiment in this article extended studies by A. W. Inhoff and K. Rayner (1986) and J. M. Henderson and F. Ferreira (1990) to determine how the printed frequency of two adjacent words influenced the benefit of having parafoveal preview of the 2nd word. High- and low-span participants (assessed by M. Daneman and P. A. Carpenter's, 1980, Reading Span Test) were tested to determine whether working memory capacity influenced parafoveal preview benefit. Parafoveal preview benefit was determined by an interaction of both words' frequencies in first fixation and by the 2nd word's frequency in gaze duration. However, readers were generally fixated closer to the beginning of the 2nd word when the 1st word was low frequency. When the viewing distance confound was minimized, the prior word's frequency did affect parafoveal preview benefit. Parafoveal preview benefit did not vary between reading groups. Group distributions of fixation duration provided no evidence for J. M. Henderson and F. Ferreira's fixation cutoff model.
