The effect of contextual constraint on eye movements in reading was examined by asking subjects to read sentences that contained a target word that varied in contextual constraint; high-, medium-, or low-constraint target words were used. Subjects fixated low-constraint target words longer than they did either high- or medium-constraint target words. In addition, they skipped high-constraint words more than they did either medium- or low-constraint target words. The results further confirm that contextual constraint has a strong influence on eye movements during reading.
通过要求被试阅读包含目标词的句子来考察语境约束对阅读中眼球运动的影响；目标词的语境约束高低不同。被试注视低语境约束目标词的时间长于注视高语境或中语境约束目标词的时间。此外，他们跳过高语境约束词的次数多于中语境或低语境约束词的次数。结果进一步证实，语境约束对阅读过程中的眼球运动有很强的影响。
