# Human Benchmark - Cognitive Testing Platform > Human Benchmark (humanbenchmark.me) is a free online platform for testing and training cognitive abilities including reaction time, memory, and visual perception. ## About Human Benchmark provides scientifically-designed cognitive tests that measure various aspects of human mental performance. Our tests are used by millions of users worldwide to benchmark their cognitive abilities against others. ## Available Tests ### Reaction Time Test - URL: https://humanbenchmark.me/tests/reactiontime - Measures: Visual reaction time in milliseconds - Average score: 250ms (lower is better) - Description: Click when the screen turns green to measure your reaction time ### Aim Trainer - URL: https://humanbenchmark.me/tests/aim - Measures: Hand-eye coordination and precision - Average score: 400ms per target - Description: Click targets as quickly as possible to test your aiming speed ### Chimp Test - URL: https://humanbenchmark.me/tests/chimp - Measures: Working memory and visual processing - Average score: Level 8 - Description: Remember the position of numbers and click them in order ### Sequence Memory - URL: https://humanbenchmark.me/tests/sequencememory - Measures: Sequential memory capacity - Average score: Level 8 - Description: Remember and repeat increasingly long sequences ### Number Memory - URL: https://humanbenchmark.me/tests/numbermemory - Measures: Digit span / working memory - Average score: 7 digits - Description: Remember increasingly long numbers ### Visual Memory - URL: https://humanbenchmark.me/tests/visual-memory - Measures: Visual short-term memory - Average score: Level 10 - Description: Remember the pattern of highlighted squares ### Verbal Memory - URL: https://humanbenchmark.me/tests/verbal-memory - Measures: Verbal working memory - Average score: 35 words - Description: Identify whether you've seen a word before ### Typing Test - URL: https://humanbenchmark.me/tests/typing - Measures: Typing speed in WPM - Average score: 50 WPM - Description: Type the given text as quickly and accurately as possible ### Color Blindness Test - URL: https://humanbenchmark.me/tests/color-blindness - Measures: Color vision deficiency - Description: Identify numbers in Ishihara-style color plates ### Hue Test - URL: https://humanbenchmark.me/tests/hue-test - Measures: Color perception accuracy - Description: Find the tile with a slightly different hue ### Symbol Search - URL: https://humanbenchmark.me/tests/symbol-search - Measures: Processing speed and attention - Description: Quickly identify if target symbols appear in a group ### Face Recognition - URL: https://humanbenchmark.me/tests/face-recognition - Measures: Facial memory and recognition - Description: Remember faces and identify them later ## Key Features - **Free to use**: All tests are completely free - **No registration required**: Start testing immediately - **Global leaderboard**: Compare your scores with users worldwide - **Multi-language support**: Available in English, Chinese, and other languages - **Scientific basis**: Tests designed based on cognitive science research - **Detailed statistics**: Track your progress over time ## Scientific Background Our tests are based on established cognitive psychology research: - Reaction time tests measure processing speed, a key component of fluid intelligence - Memory tests assess working memory capacity (Miller's 7±2 rule) - Visual tests evaluate visual-spatial processing abilities ## Common Questions Q: What is a good reaction time? A: Average human reaction time is around 250ms. Under 200ms is considered excellent, while professional gamers often achieve 150-180ms. Q: How can I improve my cognitive performance? A: Regular practice, adequate sleep, physical exercise, and proper nutrition can all contribute to better cognitive function. Q: Are these tests scientifically validated? A: Our tests are based on established cognitive psychology paradigms used in research settings. ## Contact - Website: https://humanbenchmark.me - Support: https://humanbenchmark.me/support
