(Experiment 1) Participants executed 10 trial long sequences. Trials were organized into sequences by having low inter-trial intervals (0.5s) within a sequence and high inter-trial interval (2s) across sequence boundaries. This was further reinforced by a faded digit in the background that went from 10-9-8-…-1 across the 10 trials. (a) In Rule-Switch sessions, they executed sequences made of rule-switch trials. Trial rule was cued by the color of the outer margins: blue – choose the smaller value, green – choose the smaller font. (b) In Stroop sessions participants executed sequences made of Stroop trials where they chose the color of the print of the word from the two choices below.
