Medians (Interquartile ranges-IQR) for the variables and two-sample Wilcoxon Signed-rank tests for comparisons regarding referentiality. Significant differences are in bold.

GA: Gaze Alternation.
*corrected regarding relative size of the areas.
Obs: Gaze Alternation was only measured in absolute frequency, and variables that involved areas were only measured in duration.

GA：注视交替（Gaze Alternation）。
*已针对区域相对尺寸进行校正。
备注：注视交替仅以绝对频率进行测量，涉及区域的变量仅以时长作为测量指标。
针对各变量计算中位数（四分位距-IQR），并采用两样本Wilcoxon符号秩检验开展指称性比较。具有统计学显著性的差异以粗体标注。
