Instructions to the Subject

Three cards are going to be used throughout the experiment:

• Queen of Hearts (red back)
• Black Spade Ace (blue back)
• Red Diamond Ace (blue back)

Note that only the queen card has a red back while the two ace cards have blue backs.

The experiment is a series of trials where the three cards are presented in a row. First their backs are presented, then one of the three cards is unmasked a second later.

Your task is to identify the middle card as quickly as possible, when possible. You will indicate your response by pressing a key:

• Queen -> Press ‘Q’
• Black Spade Ace -> Press ‘S’
• Red Diamond Ace -> Press ‘D’
• Don’t know -> Press ‘N’

Now, rest your fingers on the keys ‘Q’, ‘S’, ‘D’ and ‘N’.

When you are ready, press the SPACE BAR to start.

Controls

• ESC: Interrupt and exit the experiment gracefully.
• Q, S, D, N: Response keys during trials.
• SPACE: Advance from the instruction screen.

Data Collection

Results are saved as .xpd files in the data/ directory, logging trial conditions, response accuracy, and reaction times.
