“Is the card red?”
The Identification test measures attention using a choice reaction time paradigm. The on-screen instructions ask: “Is the card red?”. A playing card is presented face down in the center of the screen. The card flips over so it is face up. As soon as it flips over the participant must decide whether the card is red or not. If it is red the participant should press “Yes”, and if it is not red the participant should press “No”. The participant is encouraged to work as quickly as they can and be as accurate as possible.
