Pure DDM parameters for best fitting model to data from Experiment 1.

<p>Data are presented separately for low and high coherence trials (integration conditions), and arrows and signal detection trials (non-integration conditions). The last column indicates the average number of trials in each of the conditions. Parameters that do not vary between conditions are indicated with a dash (-). Our scaling of the threshold parameter adheres to the Ratcliff convention according to which one of the decision thresholds is placed at zero, and the other decision threshold at the value represented by the decision threshold parameter.
