Task design. Illustration of the 3 cognitive control tasks. For the purpose of visualization, the figure for each task design was regenerated based on the stimuli and parameters described in the original publication. (A) SST1 (Xue et al. 2008)—participants are required to make left/right button presses (right index/middle finger) in response to letter “T”/”D” and try to stop the response if a beep is played. (B) Flanker (Kelly et al. 2008)—participants are required to make left/right button presses (right index/middle finger) in response to the direction of the central arrow. (C) SST2 (Zhang and Li 2012)—participants are required to make button presses (right index finger) in response to a circle and attempt to stop the response if an “X” is displayed. SST, stop-signal task.
