Human Visual Processing Test

📱 Looks like you may be on a phone or mobile device. It is recommended that you complete this test on a computer with a keyboard in a focused environment in order to see the images and record your responses correctly.

In each question, you will very briefly be shown an image.

If the image contains an animal, press the left arrow←on your keyboard. If the image does not contain an animal, press the→right arrow.

Each image will be displayed for only 20 milliseconds (a fiftieth of a second), so please keep your eyes on the screen.
