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之间关系的问题。我们提出了六个实验中，这种关系进行了检查使用的时间顺序判断任务，以指数注意分配。结果表明，数字加工的一个重要后果是空间注意的自动分配，这反过来又影响视觉事件的时间顺序的感知。假设起始时间相等，当处理小的数字（1，2）时，左侧刺激被感知为在右侧刺激之前发生，而当处理大的数字（8，9）时，右侧刺激被感知为在左侧刺激之前发生。此外，我们表明，这种注意力效应是特定的数量处理，并不推广到非数字顺序序列。(c)2006 Elsevier B.V.保留所有权利。
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. (c) 2006 Elsevier B.V. All rights reserved.
