Fig. 1.

Illustration of the cognitive flexibility task. Baseline task: Baseline or ongoing task trials present only one stimulus above the central cue and require an odd vs. even discrimination to this stimulus. Distractor inhibition trials: Two digits are presented simultaneously. The cue in the middle of the screen indicates to ignore the lower digit and respond to the upper one (odd/even discrimination). Task switch trials: Two digits are presented and the cue indicates to ignore the upper digit and respond to the lower stimulus with a < / > 5 discrimination judgment with the other hand. Ambiguous trials: Two digits are presented, but the cue does not clearly indicate which digit to respond to. This figure was originally published in Kraft et al. (2020) under a CC—BY 4.0 license
