Counting is characterized as a slow and error-prone action relying heavily on serial allocation of focused attention. However, quick and accurate counting is required for many real-world tasks (e.g., counting heads to ensure everyone is evacuated to a safe place in an emergency). Previous research suggests that task-irrelevant spatial dividers, which segment visual displays into small areas, facilitate focused attention and improve serial search. The present study investigated whether counting, which is also closely related to focused attention, can be facilitated by spatial dividers. Furthermore, the effect of spatial dividers on numerosity estimation, putatively dependent upon distributed attention, was also examined to provide insights into different types of number systems and different modes of visual attention. The results showed profound performance improvement by task-irrelevant spatial dividers in both counting and numerosity estimation tasks, indicating that spatial dividers may activate interaction between number and visual attention systems. Our findings provide the first evidence that task-irrelevant spatial dividers can be used to facilitate various types of numerical cognition.

与任务无关的空间分隔器有助于计数和数量估计。
计数的特点是一种缓慢且容易出错的动作,严重依赖于集中注意力的连续分配。然而,许多实际任务都需要快速准确的计数(例如,计数头以确保在紧急情况下将每个人都疏散到安全的地方)。先前的研究表明,与任务无关的空间分隔线将视觉显示分割成小区域,有助于集中注意力并改进序列搜索。本研究调查了空间分隔器是否可以促进计数,这也与集中注意力密切相关。此外,还研究了空间分隔器对数量估计的影响,推测取决于分布式注意力,以提供对不同类型的数字系统和不同视觉注意力模式的见解。结果表明,在计数和数量估计任务中,任务无关的空间划分器的性能都有了显著的提高,这表明空间划分器可能会激活数字和视觉注意力系统之间的交互。我们的研究结果提供了第一个证据,证明与任务无关的空间划分器可用于促进各种类型的数字认知。
