本研究通过128名参与者的实验，探究数据叙事增强可视化在不同认知复杂度任务中的效果，发现其有效支持低阶任务，但对高阶任务正确性无显著帮助，却能提升复杂任务的完成效率。
中文摘要 AI 辅助
数据叙事（DS）这一新兴概念表明，通过注释和叙述增强可视化，可以使复杂数据比传统可视化更具洞察力。以往研究发现，对于识别关键数据点或主要信息等简单任务，DS增强可视化比传统可视化更有效。然而，尚无先前工作探讨DS增强在不同认知复杂度水平下对任务完成的影响程度。我们通过一项研究填补了这一空白，该研究中128名参与者基于四个可视化（两个折线图和两个等值区域图，分别带有或不带DS元素）完成任务，这些任务涵盖基于布鲁姆分类法的一系列复杂度，该分类法在数据可视化中用于按从低阶到高阶思维层次对任务进行分级。结果表明，虽然DS增强可视化有效支持低阶任务（查找数据点和理解见解），但它们不一定有助于高阶任务（应用、分析、评价和创造）的正确完成。然而，DS增强确实提高了参与者完成复杂任务的效率。
英文摘要
The emerging concept of data storytelling (DS) suggests that enhancing visualisations with annotations and narratives can make complex data more insightful than conventional visualisations. Previous works found that DS-enhanced visualisations are more effective than conventional visualisations for simple tasks like identifying key data points or the main message. However, no previous work has explored the extent to which DS enhancements influence task completion across different levels of cognitive complexity. We address this gap by presenting the results of a study where 128 participants completed tasks based on four visualisations (two line charts and two choropleth maps, either with or without DS elements) spanning a range of complexity based on Bloom's taxonomy, which has been applied in data visualisation to categorise tasks hierarchically from lower to higher-order thinking. Results suggest that while DS-enhanced visualisations effectively support lower-order tasks (finding data points and understanding insights), they don't necessarily aid the correct completion of higher-order tasks (application, analysis, evaluation and creation). However, DS enhancements improve how efficiently participants complete complex tasks.
