Results of the statistical analysis.

ANCOVA’s were done for each of the four dependent variables General Liking, Perceived Flow, Perceived Topic Clarity, and Perceived Structure Clarity. The ANCOVA’s had three factors: Poem Difficulty (Low, High), Font Readability (Low, High) and Experiment (Exp. 1, Exp. 2, Exp. 3). The covariates Age and the answer to the question ‘Do you consider yourself to be a poetry lover?’ were added as covariates to explain additional variance. Note that for none of the dependent variables a statistically significant 3-way interaction was observed. We therefore did not analyze the data per experiment. We did observe a Poem Difficulty x Font Readability interaction for three of the four dependent variables, indicating that Font Readability has a differential effect on poems that have low or high difficulty.

针对四个因变量——总体喜爱度、感知心流、感知主题清晰度与感知结构清晰度，分别开展了协方差分析（ANCOVA）。本次协方差分析包含三个实验因素：诗歌难度（低、高）、字体可读性（低、高）以及实验组别（实验1、实验2、实验3）。研究纳入年龄与“你是否认为自己是诗歌爱好者？”这一问题的作答结果作为协变量，以解释额外的变异量。需注意，所有因变量均未观测到具有统计学意义的三阶交互效应，因此我们未按实验组别对数据进行单独分析。不过我们在四个因变量中的三个上观测到了诗歌难度与字体可读性的交互效应，这表明字体可读性对低难度与高难度诗歌的影响存在差异。
