Free Cognitive Function & Brain Processing 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.
