Fig 1.
Heatmaps illustrate fixation distributions across maps under single and paired-viewing conditions, using a green-to-red colour scale for shorter to longer fixation durations. Single- and paired-viewing conditions are shown in the first/third and second/fourth columns, respectively. Spatial common ground generally exhibits an upper-central tendency. Substantial overlap between conditions suggests that image-based saliency predominantly drives visual attention, over social context.
Fig 2.
Box plots of gaze metrics for maps.
Box plots illustrate five gaze metrics across all maps (single-viewing in light grey and paired-viewing in dark grey): (a) total fixation duration (s), (b) normalised fixation duration (%), (c) fixation count, (d) average fixation duration (ms), and (e) proxy scanpath length (pixels). Whilst total fixation durations were comparable between conditions, paired viewing showed higher fixation counts, shorter average fixation durations, and longer scanpaths. Each plot displays the range (excluding outliers), interquartile range, median, and mean (triangle overlay).
Fig 3.
Fixation heatmaps for paintings.
Heatmaps show fixation distributions for two paintings, based on data from all participants in both single-viewing (a-b) and paired-viewing (c-d) conditions.
Fig 4.
Box plots of gaze metrics for paintings.
Box plots depict five gaze metrics for two paintings (single-viewing in light grey and paired-viewing in dark grey): (a) total fixation duration (s), (b) normalised fixation duration (%), (c) fixation count, (d) average fixation duration (ms), and (e) proxy scanpath length (pixels). On average, single viewing showed slightly shorter dwell times, lower fixation counts, slightly longer average fixation durations, and significantly shorter scanpath lengths. Each plot shows the range (excluding outliers), interquartile range, median, and mean (triangle overlay).
