我们移动眼睛不仅是为了获取信息，也是为了向同伴提供信息。后者的眼球运动可以被认为是目标导向的行动，以引起我们的对手的变化。在两个眼动追踪实验中，参与者看着中性的面孔，这些面孔在目光落在他们身上100毫秒后改变了面部表情。我们发现，参与者预期的面部表情的变化，并直接他们的第一眼扫视更经常的一个中性的脸的嘴部区域即将变成一个快乐的一个和一个中性的脸的眉毛区域即将变成一个愤怒的表情。此外，响应于面部表情的扫视被更快地发起到先前触发表情的位置。眼跳效应协会很容易获得，并用于指导眼睛，如果参与者自由选择下一个看哪里（实验1），但如果眼跳是由外部刺激（实验2）触发。
We move our eyes not only to get information, but also to supply information to our fellows. The latter eye movements can be considered as goal-directed actions to elicit changes in our counterparts. In two eye-tracking experiments, participants looked at neutral faces that changed facial expression 100 ms after the gaze fell upon them. We show that participants anticipate a change in facial expression and direct their first saccade more often to the mouth region of a neutral face about to change into a happy one and to the eyebrows region of a neutral face about to change into an angry expression. Moreover, saccades in response to facial expressions are initiated more quickly to the position where the expression was previously triggered. Saccade-effect associations are easily acquired and are used to guide the eyes if participants freely select where to look next (Experiment 1), but not if saccades are triggered by external stimuli (Experiment 2).
