Figure 1.

The C-PRO cognitive paradigm. First, an instruction screen presented the rules for a given task (3925 ms). Participants next applied these rules to pairs of consecutively presented audiovisual stimuli (auditory waveforms are visually depicted here but were only presented audibly to participants). Two example task-rule sets are depicted, as well as how participants were trained to interpret the rules (e.g., rule descriptions on the right-most portion of the figure; see Materials and Methods for details). The 12 possible rules are listed on the right.
