Results from the learning session.

<p>(a) Proportion of trials on which the higher-valued tile was chosen, as a function of trial number. Blue dashed line indicates chance performance. Red dashed line indicates the proportion predicted based on reports in the subsequent testing session. (b) Frequency with which tiles of each value were revealed during the learning session (black), and number of trials elapsed since the last presentation of a tile value at the end of the session (blue). (c) Proportion of trials (black symbols) on which the higher-valued tile was chosen, as a function of presented tile value, at the end of the session (final 25 trials). Every trial on which a tile of a specific value was presented as an option is included in each data point, therefore each trial contributes to two datapoints. Red symbols indicate the proportion predicted based on data from the testing session. (d) Proportion of trials on which the higher-valued tile was chosen, for each of the possible pairs of tiles (ordered by increasing value).
