Neurally-constrained modeling of human gaze strategies in a change blindness task
Fig 6
Comparison between human and model performance.
A. (Left) Joint distribution of saccade amplitude and saccade turn angle for human participants (averaged over n = 39 participants). Colorbar: Hotter colors denote higher proportions. (Right) Same as in the left panel, but for model, averaged over n = 40 simulations. B. Correlation between change detection success rates for human participants (x-axis) and the model (y-axis). Each point denotes average success rates for each of the 20 images tested, across n = 39 participants (human) or n = 40 iterations (model). Error bars denote standard error of the mean across participants (x-axis) or simulations (y-axis). Dashed gray line: line of equality. C. Average absolute deviation from human performance of the sequential probability ratio test (SPRT) model (Model, leftmost bar), for a control model in which evidence decayed rapidly (Control 1, γ = 1; second bar from left), for a control model in which the stopping rule was based on the derivative of the posterior odds ratio (Control 2; third bar from left), or for a control model which employed a random search strategy (Control 3, T = 104; rightmost bar). p-values denote significance levels following a paired signed rank test, across n = 20 images (*p < 0.05).
