我们通过使用静态图研究了编号箭头对机械运动学表示构造的影响。本科生参与者观看了描绘冲水箱的两阶段图（带或不带编号箭头），并逐步回答了有关其功能的问题。与非箭头组相比，箭头组表现出更高的整体准确性，并且在连续关系测量上犯的错误更少。箭头组还花费更多时间查看与操作序列相关的组件，并且具有更长的首次通过注视时间和更短的扫视长度。无箭头组在两个图表之间进行了更多的扫视。转移概率的分析表明，两组都根据组件的连续关系来看待组件。箭头组遵循编号箭头，而非箭头组的独特途径是比较两个图。这些发现表明，编号箭头提供感知信息，但也促进认知处理。 (C) 2014 Elsevier Ltd. 保留所有权利。
We investigated the influence of numbered arrows on construction of mechanical kinematic representations by using static diagrams. Undergraduate participants viewed a two-stage diagram depicting a flushing cistern (with or without numbered arrows) and answered questions about its function, step-by-step. The arrow group demonstrated greater overall accuracy and made fewer errors on the measure of continuous relations than did the non-arrow group. The arrow group also spent more time looking at components relevant to the operational sequence and had longer first-pass fixation times and shorter saccade lengths. The non-arrow group made more saccades between the two diagrams. Analysis of transition probabilities indicated that both groups viewed components according to their continuous relations. The arrow group followed the numbered arrows whereas the unique pathway of the non-arrow group was to compare the two diagrams. These findings indicate that numbered arrows provide perceptual information but also facilitate cognitive processing. (C) 2014 Elsevier Ltd. All rights reserved.
