Schematic of tasks. (a) ANT. (b) Cued task switching. (c) CCTHot. (d) DPX. (e) Discount delaying task. (f) Stop-signal task. Schematic of a typical stop-signal task. The go stimulus stays on screen for 850 ms. If the stop signal delay (SSD) is less than 350 ms, only the go stimulus will be on screen until the SSD, then both go stimulus and stop signal will be on screen for 500 ms, followed by just the go stimulus on screen for 850ms-500ms-SSD. If the SSD is greater than 350 ms, the stop signal was on screen, along with the fixation cross, even after the go stimulus disappeared. (g) Motor selective stop signal. Schematic of a typical motor selective stop-signal task. The go stimulus stays on screen for 850 ms. If the stop signal delay (SSD) is less than 350 ms, only the go stimulus will be on screen until the SSD, then both go stimulus and stop signal will be on screen for 500 ms, followed by just the go stimulus on screen for 850ms-500ms-SSD. If the SSD is greater than 350 ms, the stop signal was on screen, along with the fixation cross, even after the go stimulus disappeared. Participants had to make a response even if a stop-signal was presented if the go stimulus was a non-critical shape. (h) Stroop. (i) WATT. (j) Survey medley.
