A genuinely abstract number representation is thought to be capable of representing the numerosity of any set of discrete elements whether they were sequentially or simultaneously presented. Recent neuroimaging studies, however, demonstrate that different area of intraparietal sulcus have been found to play a role in extracting numerosity across simultaneous or sequential presentation during a quantification process, suggesting the existence of a format-dependent numerical system. To test whether behavioral evidence exists for format-dependent numerical processing in human adults, we measured Weber fractions of numerosity discrimination in sequential stimuli, simultaneous stimuli, and cross-format stimuli with a carefully controlled experimental procedure. Results showed distinct differences between the performance of the simultaneous and that of the sequential condition, supporting the existence of the format-dependent process for the numerosity representation. Taken together, our findingssuggest that the numerical representation may involve a complex set of multiple stages.

真正抽象的数字表示被认为能够表示任何一组离散元素的数量，无论它们是顺序呈现还是同时呈现。然而，最近的神经影像学研究表明，在量化过程中，顶内沟的不同区域在提取同时或顺序呈现的数值方面发挥着作用，这表明存在依赖于格式的数值系统。为了测试成人中依赖于格式的数字处理是否存在行为证据，我们通过仔细控制的实验程序测量了顺序刺激、同时刺激和跨格式刺激中数字辨别的韦伯分数。结果显示同时条件和顺序条件的性能之间存在明显差异，支持数字表示的格式相关过程的存在。总而言之，我们的研究结果表明，数字表示可能涉及一组复杂的多个阶段。
