Figure 2.

Psychometric and chronometric data during task switching are shown for each monkey separately. A, B, We fitted the psychometric function for the direction discrimination task (A) and that for the depth discrimination task (B) simultaneously using three models. Each row shows the fitted psychometric function of each model. The different colors denote different strengths of the irrelevant stimulus feature. C, D, The mean reaction time as a function of the relevant stimulus strength for the direction discrimination task (C) and for the depth discrimination task (D). E–H, Data for monkey K. Conventions are the same as for A–D.
