In this article, we present an investigation into the use of visual cues during number line estimation and their influence on cognitive processes for reducing number line estimation error. Participants completed a 0-1000 number line estimation task before and after a brief intervention in which they observed static-visual or dynamic-visual cues (control, anchor, gaze cursor, mouse cursor) and also made estimation marks to test effective number-target estimation. Results indicated that a significant pre-test to post-test reduction in estimation error was present for dynamic-visual cues of modelled eye-gaze and mouse cursor. However, there was no significant performance difference between pre- and post-test for the control or static anchor conditions. Findings are discussed in relation to the extent to which anchor points alone are meaningful in promoting successful segmentation of the number line and whether dynamic cues promote the utility of these locations in reducing error through attentional guidance.
在本文中，我们展示了一项关于在数字线估计过程中视觉线索的使用及其对减少数字线估计误差的认知过程影响的调查。参与者在一次简短干预前后完成了一项0 - 1000数字线估计任务，在干预过程中他们观察了静态视觉或动态视觉线索（对照组、锚点、注视光标、鼠标光标），并且还做出估计标记以测试有效的数字目标估计。结果表明，对于模拟的目光注视和鼠标光标的动态视觉线索，测试前到测试后的估计误差有显著降低。然而，对照组或静态锚点条件下测试前和测试后没有显著的表现差异。我们将结合仅锚点在促进数字线成功分割方面的意义程度，以及动态线索是否通过注意力引导提高这些位置在减少误差方面的效用，来讨论这些发现。
