Figure 4.

The temporal sequence of contextual cues and outcome stimuli on P-S cuing and on F-B cuing conditions, separately for certain and uncertain conditions. The figure illustrates the initial three trials of task runs. Contextual cues are provided on P-S cuing, but not on F-B cuing (depicted as []), which leads to erroneous task-set repetitions on state-transition trials, and concomitantly to “wrong”-outcomes (O_w). Note the uncertainty of outcomes (“right” or “wrong,” O_r/w) on uncertain P-S state-transition trials and on uncertain F-B state-repetition₁ trials. Depending on the outcome valence, task-set repetitions or task-set switches are required on subsequent trials.
