Wetin this test dey measure
E dey measure how many places you fit remember in order. Na screen version of the Corsi block-tapping task, wey dem dey use plenty to test short-term memory for space and sight. For the original, one examiner dey tap blocks wey dem arrange for board, one by one, and you tap the same blocks for the same order 1.
To remember places wey come one after another, your memory dey work small different from when you remember one pattern wey you see all at once 2. The test for picture memory dey check that second kind.
How the test dey work
- Squares for 3×3 grid dey flash one after another. When the sequence finish, tap the same squares for the same order.
- The first sequence get 2 squares, and every correct answer dey add one. One square fit show again, but e no go show two times one after another.
- You get 2 tries for each length; if you miss every try for one length, the test end. One wrong tap go end that try straight away.
How to understand your score
Your score na the longest sequence wey you tap back for the correct order. The research version dey use nine blocks wey dem put for fixed, uneven places, and dem standardize the scoring and norms using that setup 1. This grid get different arrangement, so e better make you compare your score here with your other tries, no be with clinical results.
Wetin fit help or make am hard
Plenty people dey follow the path with their eyes or dey call the positions for their mind. Both ways dey okay; just use the same way each time you play. Tiredness, distraction, and simply getting used to the game fit all change your score.

How this test works
This game tests how many places you can remember in the right order. Squares in a 3 by 3 grid flash one at a time. When they stop, tap the same squares in the same order. You start with 2 squares, and every right answer adds one. You get 2 tries at each length, and missing both ends the game. Your score is the longest sequence you repeated correctly. It is based on the Corsi block-tapping task, used in psychology since 1972.
