The role of visual attention in counting and numerosity estimation

2021财年的实验结果表明，当不能进行基于颜色的分割时，计数性能会受到抑制。具体地说，当显示器中的物体被随机着色时，与基于颜色分割的显示器相比，参与者更难对其进行计数。在2022财年，进行了一项后续实验，以调查在对象颜色无法用于分割显示器的情况下，注意线索是否能够改善计数性能。这项实验使用的是随机着色的对象显示，这使得根据对象的颜色分割对象变得困难。注意线索被提供以将参与者的注意力引导到具有线索颜色的物体。结果表明，即使在基于颜色的分割不可能的情况下，注意线索也可以提高计数性能。这表明，注意线索可以作为一种有效的替代基于颜色的分割来提高计数性能。

The results of the FY 2021 experiments showed that counting performance was inhibited when color-based segmentation was not possible. Specifically, when the objects in the display were randomly colored, participants had more difficulty counting them compared to displays where color-based segmentation was possible.In FY 2022, a follow-up experiment was conducted to investigate whether attentional cues can improve counting performance in situations where object color cannot be used to segment the display. This experiment used displays of objects that were randomly colored, making it difficult to segment the objects based on their color. Attentional cues were provided to direct the participant's attention to objects having the cued color. The results showed that attentional cues can improve counting performance even in situations where color-based segmentation is not possible. This suggests that attentional cues can serve as an effective alternative to color-based segmentation in improving counting performance.
