Learning function for the transitive inference (TI) task for one subject, Coltrane.

<p>“D1” corresponds to adjacent pairs, “D2” to pairs of items two positions apart, and so forth. <i>A</i>: Mean accuracy in 18-trial blocks, as a function of implicit distance between items. <i>B</i>: Logitistic regression model fit performed in isolation on each pair of distance 2 (orange dashed), distance 4 (green), and distance 6 (blue dotted). <i>C</i>: Logistic regression model fit for <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0070285#pone.0070285.e023" target="_blank">Equation 1</a> presented for each of the eight distances between items.
