作者研究了数字比较过程的时间动态，提出了数字与刺激起始时间（SOA）为0，70，140，或210毫秒。实验1使用标准的完全配对比较设计，混淆数字和概率信息的数字第一。结果表明，SOA的大的影响，不同的数字对的特征不同。这些结果在实验2中发生了很大的变化，实验2使用了一种去除了任何概率偶然性的设计。实验三考察了数字时间顺序的一致性效应。作者制定了两个模型，并与数据进行了比较，这两个模型在数字特定和SOA特定效应的位置方面存在不同的假设：参与者要么使用部分数字提前信息来准备建议的响应，要么只有在两个数字都出现后才开始处理数字信息。当概率意外事件被删除时，数据支持后一种模型。
The authors studied the temporal dynamics of digit comparison processes by presenting the digits with a stimulus onset asynchrony (SOA) of 0, 70, 140, or 210 ms. Experiment 1 used the standard complete paired comparison design that confounds numerical and probabilistic information in the digit presented first. The results showed large effects of SOA that differed characteristically for different digit pairs. These results changed considerably in Experiment 2, using a design that removed any probabilistic contingencies. Experiment 3 examined a form of congruity effect related to the temporal order of the digits. The authors formulated and compared to the data 2 models that differed in their assumptions about the loci of digit-specific and SOA-specific effects: Either the participants use partial numerical advance information to prepare for the suggested response, or they start to process numerical information only after both digits are presented. When probabilistic contingencies were removed, the data favored the latter model.
