Memory span
Repeat a sequence of blocks in order. The longest you can hold shortens with age.
How to do it
- Blocks light up one at a time. Watch the order.
- When they stop, tap the same blocks in the same order.
- It starts with two blocks and adds one each round, with two tries at each length.

What the research found
This is the Corsi block test, a standard check of short-term visual memory. In 340 healthy adults aged 21 to 89, the average span was about 5 blocks. It was shorter at older ages and longer with more years of school, so your span is compared with people of your age and schooling. The study used wooden blocks on a board, so this on-screen version is a rough guide.
Studied in: 340 healthy adults aged 21 to 89 in Italy.
