“Has the Card Turned Over?”

Test Description

The Detection test measures processing speed using a simple reaction time paradigm. The on-screen instructions ask: “Has the card turned over?”. 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 the card flips over the participant must press “Yes”. The participant is encouraged to work as quickly as they can and be as accurate as possible.
