Cognitive Control Training

What is CCT?

CCT is a cognitive-control training game based on the Paced Auditory Serial Addition Test (PASAT). It challenges your attention, working memory, and mental arithmetic by asking you to add consecutive numbers as you hear them.

How to Play

You’ll hear a series of numbers, one at a time. Add each new number to the number immediately before it, then enter the sum.

Example: You hear 3, then 6 → enter 9. If the next number is 2 → enter 8, because 6 + 2 = 8.

• The first number starts the sequence, so no answer is needed yet.
• Respond before the next number is played.
• Always add the two most recently heard numbers—not your previous answer.
• Focus on accuracy and keep going if you miss one.

The session ends automatically, and your results are saved to your history. You can stop at any time.
