Fits of all 14 models to the data in Fig. 1B-C (axis labels and scales as there).

<p>VP = variable precision; EP = equal precision; AP = average precision; SP = single precision. Error bars and shaded areas represent ±1 s.e.m. in the data and the model, respectively. The number in each plot is the <i>R</i>² of the fit (for the left plot in each pair, computed over false-alarm rates and unconditioned hit rates). Frame color indicates model goodness of fit relative to the winning model, as obtained from Bayesian model comparison (<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0040216#pone-0040216-g004" target="_blank">Fig. 4</a>).
