Fig 9
Comparison between art and pseudo-art of average saccade duration during first (a) and second (b) visit in a gallery.
The boxplots show medians for a given group (horizontal line) together with the middle 50% of the data denoted by interquartile range box (the distance between the first and third quartiles) and ranges for the bottom 25% and the top 25% of the data values, excluding outliers (whiskers). A ** above the horizontal line over 1st visit boxplot denotes p < 0.01.
