MIND-WANDERING (SART):
The SART is a type of Go/NoGo task in which the nogo stimulus is presented very infrequently.
TASK
Participants are presented with a single digit 1-9 in the middle of the screen in varying fontsizes.
The digit disappears after a short while and is replaced with a mask (circle with an X).
Participants are asked to press the SPACEBAR if any digit other than 3 is presented and to withhold the response
if digit 3 presented.
