Go / No-Go test

Go / No-Go test measures sustained attention, inhibition, and impulsivity

"The test “Go/ No-Go” assesses sustained attention, inhibition, and impulsivity by measuring whether and how quickly a user presses a button in response to a target stimulus. Target stimuli are small white squares that appear at the top of a black screen. There are also nontarget stimuli, small white squares that appear at the bottom of the black screen, which the user is instructed to ignore. Stimuli are presented one at a time, and statistics are kept on how often a target stimulus is ignored by the user, how often the user presses the button in response to a non-target stimulus, how quickly the user presses the button in response to target stimuli, and how often the user presses the button too soon for target stimuli. This combination of measurements assessed sustained attention--the ability of a user to pay attention in spite of boredom and inactivity, and inhibition control-the ability to react quickly and accurately to target stimuli while managing to avoid reacting to non-targets or reacting too early to targets."
