Free Cognitive Function & Brain Speed Test

This test measures cognitive processing speed and attention. Please review the tutorial first if this is your first time taking the cognitive performance test, — it’s worth the time to understand how to take this test. The goal of this cognitive function test is both accuracy and performance speed. A reaction speed of under 500 milliseconds is considered good performance, and very hard to accomplish the first few times taking the test.

Free Short Term Visual Memory Test

A series of images will appear during the test. When an image is repeated:

PC and laptop users – press the space bar on your keyboard when you see a repeated image. Tablet and Smartphone users – touch only repeated images.

Good performance is 90%+ accuracy on repeated images. Good average response time for selecting repeated images is < 900 milliseconds (0.9 seconds).
