In the present study, we focus on the priming effect of colour on mitigating the attentional reorientation cost, which is led by re-constructing the frame of reference for attention shift and visual search in sequential presentations of temporal data visualization. The study involves two experiments using complementary recordings of behavioural performance and eye-tracking events. Two aspects of colour primes are highlighted: the prime validity and the colour perceptual accessibility. A task paradigm integrating the feature search and keeping-track task was adopted in our experiments. In Experiment 1 (with a group of 16 participants), we confirmed the colour priming effect by comparing the priming condition to the neutral baseline. Furthermore, global colours that are with high perceptual accessibility generated more evident priming effects than local colours. However, more interferences in misguiding the attention to task-irrelevant regions were found when the global primes were invalid. In Experiment 2 (with another group of 15 participants), we verify the finding in Experiment 1 that global colours produced more pronounced priming effects in alleviating the attentional reorientation cost by comparing two groups of real-world visualizations with either global or local colours as the prime. Large saccades were initiated much earlier, and the search efficiency got improved when provided with global colours. We conjecture that the facilitatory effect from global colours may stem from its benefit on the pre-attentive processing of the search field. The research findings provide evidence for utilizing colours as the primes in mitigating the attentional reorientation cost and accelerating visual search in sequential presentations.

颜色在时间数据可视化的顺序呈现中帮助注意力重新定向的启动效应：来自眼动追踪的证据

在本研究中，我们专注于颜色对减轻注意力重定向成本的启动效应，这是通过在时间数据可视化的顺序呈现中重新构建注意力转移和视觉搜索的参考框架来引导的。该研究涉及两个使用行为表现和眼动追踪事件的互补记录的实验。强调了颜色素数的两个方面：素数有效性和颜色感知可访问性。我们的实验采用了一种集成了特征搜索和跟踪任务的任务范式。在实验 1（有 16 名参与者）中，我们通过将启动条件与中性基线进行比较来确认颜色启动效应。此外，具有高感知可访问性的全局颜色比局部颜色产生更明显的启动效果。然而，当全局素数无效时，会发现更多干扰将注意力误导到与任务无关的区域。在实验 2（与另一组 15 名参与者）中，我们验证了实验 1 中的发现，即全局颜色在减轻注意力重新定向成本方面产生了更明显的启动效应，方法是将两组真实世界的可视化与全局或局部颜色进行比较。鼎盛时期。大型扫视启动得更早，并且在提供全局颜色时提高了搜索效率。我们推测，全局颜色的促进作用可能源于它对搜索字段的预注意处理的好处。
