“Have you seen this card before?”
The One Card Learning test measures visual memory using a pattern separation paradigm. The on-screen instructions ask: “Have you seen this card before in this test?”. A playing card is presented face up in the center of the screen and the participant must decide whether they have seen the card before in this test. The participant is encouraged to work as quickly as they can and be as accurate as possible.
