In an eye-tracking experiment during reading, we examined the repetition effect, whereby words that are repeated in the same paragraph receive shorter fixation durations. Target words that were either high-frequency or low-frequency words and of which the parafoveal preview was either correct or with all letters replaced were embedded three times in the same paragraph. Shorter fixation times and higher skipping rates were observed for high-frequency compared to low-frequency words, words for which the parafoveal preview was correct versus incorrect, and as the word was being repeated more often. An interaction between frequency and repetition indicated that the reduction in fixation times due to repetition was more pronounced for low-frequency words. We also observed influences of word repetition on parafoveal processing, as repeated words were skipped more often. An interaction between parafoveal preview and repetition indicated an absent repetition effect when the preview was incorrect, but this effect was short lived, as it was restricted to the first fixation duration on the target word.
在阅读过程中的眼动实验中，我们研究了重复效应，即在同一段落中重复的单词会得到更短的注视持续时间。目标词是高频词或低频词，其视上预视无论是正确的还是所有字母都被替换的，在同一段落中嵌入三次。与低频词相比，高频词的注视时间更短，跳过率更高，视上预视正确的词比不正确的词，以及单词重复的次数越多。频率和重复之间的相互作用表明，由于重复而导致的注视时间减少在低频词中更为明显。我们还观察到单词重复对视上加工的影响，因为重复的单词被跳过的频率更高。视上预视和重复之间的相互作用表明，当预视不正确时，重复效应不存在，但这种效应是短暂的，因为它仅限于对目标单词的第一个注视持续时间。
