Variability in category prior probabilities computed as running estimates of over different lengths of stimulus history (i.e., number of trials).

<p>Panels depict mean ± 1 SD of running averages of the stimulus history in the experiment for = 0.25, 0.5, and 0.75, respectively. Shading of data points denote different bin lengths. For comparison, the true estimates ± 1 SD of the largest noise levels from <a href="http://www.ploscompbiol.org/article/info:doi/10.1371/journal.pcbi.1003715#pcbi-1003715-g014" target="_blank">Figure 14</a> are depicted with solid and dashed lines. Colors of lines are the same as in <a href="http://www.ploscompbiol.org/article/info:doi/10.1371/journal.pcbi.1003715#pcbi-1003715-g014" target="_blank">Figure 14c</a>.
