我们通过记录注意力部署以及具有和没有公开眼动反应的相关空间数量映射的时间过程来检查数字和空间之间的自发关联。在实验1中，参与者在收听数字名称时保持了中央固定。在实验2中，他们在听觉编号表现后进行了水平目标直接扫视。在这两个实验中，我们在数量呈现期间和之后都在水平空间中不断测量自发的眼部漂移。实验2还测量了数字显示后视觉探针导向的扫视。在两个实验中，在数字表示期间和之后出现了与水平心理数线一致的可靠眼漂移。我们的结果为与水平空间数量映射机制相关的动眼共振效应的隐式和自动性提供了新的证据。
We examined the spontaneous association between numbers and space by documenting attention deployment and the time course of associated spatial-numerical mapping with and without overt oculomotor responses. In Experiment 1, participants maintained central fixation while listening to number names. In Experiment 2, they made horizontal target-direct saccades following auditory number presentation. In both experiments, we continuously measured spontaneous ocular drift in horizontal space during and after number presentation. Experiment 2 also measured visual-probe-directed saccades following number presentation. Reliable ocular drift congruent with a horizontal mental number line emerged during and after number presentation in both experiments. Our results provide new evidence for the implicit and automatic nature of the oculomotor resonance effect associated with the horizontal spatial-numerical mapping mechanism.
