尽管对数值大小的处理进行了大量的研究（例如，由数字5表示的量），很少有研究调查该量值信息如何与数字的序数属性相关（例如，5是第五个整数）。在本研究中，我们调查了订单相关的处理的数字，以及一年中的几个月，与一个新的排序任务，看看是否顺序信息的处理不同于处理的大小信息。在实验I和2中，参与者被展示了三个数字（实验1）或三个月（实验2），并被要求指出刺激是否按正确的顺序进行。在实验3中，参与者再次看到三个数字;然而，现在他们被指示这三个数字是向前、向后还是混合排列。虽然数字比较任务通常揭示距离效应（随着两个数字之间距离的增加，比较变得更容易），但这三个实验揭示了不同的结果模式。当刺激跨越边界时存在反向距离效应（即，当数字跨越十年或月跨越年边界时）以及当刺激没有跨越边界时距离没有影响（即，当数字在十年内，月份在1月至12月日历年内时）。这些数据表明，额外的机制参与了订单信息的处理：扫描机制和长期记忆检查机制。
Despite a great deal of research on the processing of numerical magnitude (e.g., the quantity denoted by the number 5), few studies have investigated how this magnitude information relates to the ordinal properties of numbers (e.g., the fact that 5 is the fifth integer). In the present study, we investigated order-related processing of numbers, as well as months of the year, with a novel ordering task to see whether the processing of order information differs from the processing of magnitude information. In Experiments I and 2, participants were shown three numbers (Experiment 1) or three months (Experiment 2) and were required to indicate whether the stimuli were in the correct order. In Experiment 3, participants were again shown three numbers; however, now they were instructed to indicate whether the three numbers were ordered in a forward, backward, or mixed direction. Whereas number comparison tasks typically reveal distance effects (comparisons become easier with increased distance between two numbers), these three experiments reveal a different pattern of results. There were reverse distance effects when the stimuli crossed a boundary (i.e., when numbers crossed a decade or months crossed the year boundary) and no effect of distance when the stimuli did not cross a boundary (i.e., when numbers were within a decade and months were within the January-December calendar year). These data suggest that additional mechanisms are involved in the processing of order information: a scanning mechanism and a long-term memory checking mechanism.
