Try browser-based reaction time, memory and attention games; results are for personal practice, not neuropsychological diagnosis.
Measure reaction speed in milliseconds and compare your own attempts without fabricated population averages.
Short-term memory challenge. Keep track of seen vs. new words as the list grows longer.
WPM Test. Calculate your Words Per Minute and keyboard accuracy in a 60-second sprint.
How fast do you read? Measure your WPM and comprehension level with a standard passage.
Are you smarter than a chimpanzee? Test your working memory and iconic memory span.
How long a digit sequence can you recall? Take a browser memory challenge and track your personal best.
Vigilance Test. Measure your ability to maintain focus on a monotonous task without spacing out.
Clicks Per Second. Test your finger speed and mouse clicking stamina.
Spacebar Counter. Measure thumb velocity and keyboard latency.
Cognitive flexibility challenge. Say the color of the word, not the word itself.
Reaction times depend on the task, input device, refresh rate, and person. Compare repeat attempts on similar hardware instead of relying on a single population average.
Practicing a specific test can improve familiarity and performance on that task. Improvement on a game does not by itself demonstrate broad cognitive gains.
The Stroop Effect is a demonstration of interference in the reaction time of a task. It shows that processing the meaning of a word (e.g., reading 'RED') is faster and more automatic than identifying the ink color (e.g., green ink).
Cognition is not a single trait but a collection of executive functions. Some tasks are inspired by familiar research paradigms, but this site does not provide standardized clinical assessments.
