A formal simulation illuminating the psychophysical situation in the sparse-middle-dense task of Experiment 3. The simulated subject performed 600,000 trials in that task with a Gaussian perceptual error of 6 steps along the continuum and with sparse-uncertain and uncertain-dense criteria, respectively, of 26 and 36. The graph shows the proportion of all trials at each density level on which the stimulus would have been misclassified into the wrong perceptual category (e.g., an objectively middle stimulus perceived and classified as sparse or dense).
