A focused Stroop test with classic and rule-switching modes. Stroop Test is a lightweight browser-based attention test based on the Stroop effect. It includes two test modes: • Classic Mode — identify the displayed color while ignoring the written word. • Rule-Switching Mode — follow changing rules and respond according to the current instruction. The test is designed to challenge attention, response control, and your ability to handle conflicting visual information. Each session provides clear results so you can try again and compare your performance. Stroop Test runs directly in Chrome with a simple interface and no unnecessary setup.
