Monkey reaction times are consistent with (r)MSPRT using depleted discrimination information.

<p>(a, b) Mean reaction time of monkeys (lines) with 99% Chebyshev confidence intervals (shading) and (r)MSPRT predictions for correct (a; <a href="http://www.ploscompbiol.org/article/info:doi/10.1371/journal.pcbi.1006033#pcbi.1006033.e024" target="_blank">Eq 14</a>) and error trials (b; <a href="http://www.ploscompbiol.org/article/info:doi/10.1371/journal.pcbi.1006033#pcbi.1006033.e025" target="_blank">Eq 15</a>) when using information-depleted statistics (MT parameter set Ω_<i>d</i>). (r)MSPRT results are means of 100 simulations with 3200, 4800 total trials each for <i>N</i> = 2, 4, respectively. Confidence intervals become larger in error trials because monkeys made fewer mistakes for higher coherence levels. (c-f) ‘Violin’ plots of reaction time distributions (vertically plotted histograms reflected about the y-axis) from monkeys (red; 766–785, 1170–1217 total trials for <i>N</i> = 2, 4, respectively) and (r)MSPRT when using information-depleted statistics (blue; single Monte Carlo simulation with 800, 1200 total trials for <i>N</i> = 2, 4).
