Working Memory
This test measures your short-term visual and auditory memory, as well as your ability to maintain sustained concentration.
Module Description
You make selections using the arrow keys based on a set of rules that change from round to round. At the same time, you must manage a secondary attention control task.
Attention Control Task (Left Bar)
On the left side of the screen, there is a black square that slowly moves downward.
Your Task
- Press the A key to push the square back upward.
- You can press 'A' at any interval.
- The goal is to prevent the square from touching the bottom.
If the square reaches the bottom, a red flash appears and a beep sound is played. This disrupts your concentration and wastes time.
Symbol Selection Task
The test alternates between two screen types: Computer Screen and Your Screen.
- On Your Screen: The target symbol is shown in the top-left.
- On Computer Screen: The target symbol is shown in the top-right.
You must use the arrow keys to select one of the symbols shown on your screen.
3. Selection Rules
Your choice is based on a hierarchy of rules:
- Select your target symbol — unless another rule blocks it.
- Do not select the computer’s target symbol.
- Do not select the symbol spoken by the computer. (What you hear matters).
- Do not select the forbidden symbol shown at the bottom of your screen.
Scoring & Strategy
- Correct answer: +1 point
- Wrong answer: −2 points
This test measures both speed and accuracy. Being too slow reduces the total score, while being too fast increases mistakes. Finding the right balance is essential.
