Abstract

In this paper 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 pre and post 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.
