Experimental Go/NoGo paradigm. Participants had to respond as fast as possible to the Go stimuli while withholding their response to the NoGo stimuli. In a given block, NoGo stimuli were either all letters of a given color or all colors of a given letter; Go trials were all the remaining stimuli. A feedback was provided on response speed and accuracy. The control and implementation intentions groups completed the same task except the way instructions were formulated.
