Shape Matching

Match the images by clicking one of the four images at the bottom that matches the image at the top.

The matching starts once you click or tap the first image and ends after you click 10 images.

The results will show you the total correct, the percentage correct, and the total time.

Why

To collect data.

I would like to collect a large amount of data - millions, even billions of data points - to help understand when people's cognitive abilities start to decline.

I am doing this for my own greedy reasons. Both my parents have alzheimer's disease. I don't want that.

The "why" for this project is to be continunued...

What data we collect

To start with, we ask for your year of birth. Want to be able to compare results across people of approximately the same age.

Everytime you play a shape matching game, we record results.
