Sustained Attention to Response (SART)

This is a test of ability to sustain attention with a response-suppression element. You see digits one at a time on the screen. The digits appear at the rate of one every two seconds. The task is to respond to every number EXCEPT 3, when you should make no response 


This is a reaction time task, so you should always respond as quickly as possible, while avoiding errors. We record the reaction times averaged over the test, and the total number of correct and incorrect responses. 

This test can be run on a Java-enabled mobile phone. The test normally lasts about three minutes.
