Human visual exploration reduces uncertainty about the sensed world
Fig 5
The performance measures in the panels of this figure are averaged over all blocks and subjects. The means and standard error of the means (error bars) are plotted per measure. The top left and right panels show the mean score per trial and the percentage correct categorization over five blocks, respectively (t(df) = 4388, *p < 0.001; t(df) = 4393, **p < 0.001). The middle left panel shows the mean saccades per trial (before categorizing the scene) and the middle right panel shows the mean time between saccades in seconds across five blocks (t(df) = 4392, ***p < 0.001, t(df) = 7774 ****p < 0.001). The histogram on the bottom panel reports the probability distribution over the number of saccades the participants made before arriving at a decision about the category of the scene.
