人类如何评估暂时积累的离散证据，并在存在相互矛盾的证据的情况下做出决定？在本研究中，我们向人类参与者展示了从两个新的对象类别中提取的对象的顺序呈现，并要求他们决定给定的呈现是否包含来自一个或另一个类别的更多对象。我们发现，无论是更不同的比例和更大的物体数量都提高了反应时间（RT）和准确性。数量的影响是独立的比率，其中与一个固定的对象比率，序列与更多的总对象有较低的RT和较低的错误率比那些总对象较少。我们在三个实验中重复了这些结果。此外，即使与总演示文稿的持续时间相等，并与运动反应分配不同的审判，仍然发现在RT的数字的影响。同样的RT的好处也存在时，对象同时显示，而不是顺序。总之，这些结果表明，对于涉及顺序显示的比较数字判断，数字有好处，这样显示更多的对象独立于对象比率和总呈现时间，导致更快的决策性能。
How do humans evaluate temporally accumulated discrete pieces of evidence and arrive at a decision despite the presence of conflicting evidence? In the present study, we showed human participants a sequential presentation of objects drawn from two novel object categories and asked them to decide whether a given presentation contained more objects from one or the other category. We found that both a more disparate ratio and greater numerosity of objects improved both reaction time (RT) and accuracy. The effect of numerosity was separate from ratio, where with a fixed object ratio, sequences with more total objects had lower RT and lower error rates than those with fewer total objects. We replicated these results across three experiments. Additionally, even with the total presentation duration equated and with the motor response assignment varied from trial to trial, an effect of numerosity was still found in RT. The same RT benefit was also present when objects were shown simultaneously, rather than sequentially. Together, these results showed that, for comparative numerosity judgment involving sequential displays, there was a benefit of numerosity, such that showing more objects independent of the object ratio and the total presentation time led to faster decision performance.
