Mental Speed Test is a free online test from Psychology Today to check your brain speed. As questions, it shows you a text and a picture at a time. You have to tell if the pair of text and picture matches or not. You can select either of the options from Correct or Incorrect. At times, an Opposite text appears at the top of the pair. When it does, you have to press Correct instead of Incorrect and vice-versa.

Based on your responses and response time, this calculator tells you your metal speed along with a brief paragraph on what you should or should not be doing.

BrainHQ is a visuals based brain speed test. What it does is, shows you a flock of birds flying multiple times. In each case, one of the birds will be different from the rest of the birds. After showing a flock, the birds disappear and you have to click on the place where the different bird was located. The location of odd bird changes each time. The duration for which the flocks are displayed also reduces as the test passes. This happens for multiple times. When the test ends, it shows your brain speed.

Stroop Effect

Stroop Effect is an online test that is very different from other tests. This test is carried out in 2 steps. In the first step, you will have to read name of colors and the text is of the same color as the name of color. Begin reading the text till its complete, then go to the next step. For the first step it records the time taken by you to read the text. In the next step, you will find names of different colors and their text color is random. In this step, you have to speak the name of the color of the text, not what’s written in the text. Once you finish reading, it again shows you the time taken. Now, a table is provided, using which you can compare both the times from step 1 and step 2 to get a score. It also tells what your score means.
