The independent and the combined influence of word length, word frequency, and contextual predictability on eye movements in reading was examined across processing stages under two priming-context conditions. Length, frequency, and predictability were used as predictors in multiple regression analyses, with parafoveal, early, late, and spillover eye movement measures as the dependent variables. There were specific effects of: (a) length, both on where to look (how likely a word was fixated and in which location) and how long to fixate, across all processing stages; (b) frequency, on how long to fixate a word, but not on where to look, at an early processing stage; and (c) predictability, both on how likely a word was fixated and for how long, in late processing stages. The source of influence for predictability was related to global rather than to local contextual priming. The contribution of word length was independent of contextual source. These results are relevant to determine both the time course of the influence of visual, lexical, and contextual factors on eye movements in reading, and which main component of eye movements, that is, location or duration, is affected.
在两种启动语境条件下，研究了单词长度、单词频率和语境可预测性对阅读中眼动的独立影响和综合影响，贯穿于各个加工阶段。在多元回归分析中，将长度、频率和可预测性用作预测变量，将副中央凹、早期、晚期和溢出眼动指标用作因变量。具体有以下影响：（a）在所有加工阶段，长度对注视位置（一个单词被注视的可能性以及在哪个位置）和注视时长均有影响；（b）在早期加工阶段，频率对单词的注视时长有影响，但对注视位置没有影响；（c）在晚期加工阶段，可预测性对单词被注视的可能性以及注视时长均有影响。可预测性的影响来源与全局而非局部语境启动有关。单词长度的影响与语境来源无关。这些结果对于确定视觉、词汇和语境因素对阅读中眼动影响的时间进程，以及眼动的哪个主要成分（即位置或时长）受到影响具有重要意义。
