Accuracy of the model and comparison to the accuracy of monkeys.

<p>Left, performance of monkeys re-drawn from [<a href="http://www.ploscompbiol.org/article/info:doi/10.1371/journal.pcbi.1004489#pcbi.1004489.ref014" target="_blank">14</a>]. The five panels show the accuracy across training days with patterns of increasing contour length; 1 line (blue), 3 (purple), 5 (green), 7 (orange) or 9 colinear lines (light blue). Note that the monkeys performed at chance level for patterns with line length 1, which are indistinguishable from distractor patterns. Solid lines are cubic spline fits. <b>Right</b>, Accuracy of the model for the same stimuli, smoothed with a Gaussian (<i>σ</i> = 100 trials). The number of iterations refers to repetitions of the same contour length, i.e. the total number of iterations is five times as large because the model was exposed to five different contour lengths.
