In this experiment, participants performed two tests of sustained attention (fixed and random SART). In both the fixed and random SARTs, participants were asked to respond to every time 1, 2, 4-9 came on screen (every number except 3). Participants had to withhold their response when an 3 was presented. In the fixed SART the numbers are presented in order 1-9, but in the random SART the numbers are pseudo-randomised.
The most common outputs from the SART are:
Previous research has shown a significant correlation between Commission Errors and both self- and other-ratings of Cognitive failures

Numbers are presented in a fixed order 1-9 and participants press on every number except 3. The number is on screen for 250ms followed by a mask (circle with cross) for 900ms. There are 225 trials (25 blocks) plus 18 trials (2 blocks) of practise.

Numbers 1-9 are presented in a random order and participants press on every number except 3. The distance between 3's is a minimum 5 stimuli and maximum 12 stimuli. The number is on screen for 250ms followed by a mask (circle with cross) for 900ms. There are 225 trials (25 blocks) plus 18 trials (2 blocks) of practise.
