Comparison between simulated and experimental reaction times and accuracy.

<p>(A) Reaction times simulated with the attractor model include a non-decision time (t_ND) of 330 ms. (B) Accuracy of the attractor model. The respective motion input ν_motion for a given level of coherence was set according to <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0043131#pone.0043131.e002" target="_blank">equation 2</a> in the <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0043131#s2" target="_blank">methods</a> section. The initial decision was determined by a firing rate threshold of 37 Hz. For comparison the experimental data from <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0043131#pone-0043131-g003" target="_blank">Figure 3</a> is shown again in lighter colors. The model fits experimental reaction times and performance well. The difference in RT between 2- and 4-choice trials is only slightly overestimated, so is the accuracy. Error bars of simulated data (SEM) are mostly hidden behind the dot markers.
