The existence of spatial components in the mental representation of number magnitude has raised the question regarding the relation between numbers and spatial attention. We present six experiments in which this relation was examined using a temporal order judgment task to index attentional allocation. Results demonstrate that one important consequence of numerical processing is the automatic allocation of spatial attention, which in turn affects the perception of the temporal order of visual events. Given equal onset time, left-side stimuli are perceived to occur before right-side stimuli when a small number (1, 2) is processed, whereas right-side stimuli are perceived to occur before left-side stimuli when a larger number (8, 9) is processed. In addition, we show that this attentional effect is specific to quantity processing and does not generalize to non-numerical ordinal sequences.
数字大小心理表征中空间成分的存在引发了关于数字与空间注意力之间关系的问题。我们进行了六个实验，其中使用时间顺序判断任务来索引注意力分配，以此检验这种关系。结果表明，数字处理的一个重要结果是空间注意力的自动分配，这反过来又会影响对视觉事件时间顺序的感知。在起始时间相同的情况下，当处理较小数字（1、2）时，左侧刺激被感知为比右侧刺激先出现，而当处理较大数字（8、9）时，右侧刺激被感知为比左侧刺激先出现。此外，我们表明这种注意力效应特定于数量处理，并不适用于非数字顺序序列。
