Reaction Time Test
Reaction Time Test
A simple visual reaction task focused on how quickly you respond to a clear screen change. Best used for tracking consistency over time under similar conditions.
Test your reaction time, memory, attention, and other cognitive skills
A simple visual reaction task focused on how quickly you respond to a clear screen change. Best used for tracking consistency over time under similar conditions.
A more demanding reaction task that combines color-based decisions and sound cues. Useful for tracking speed, accuracy, and response control when simple reaction is no longer enough.
A classic visual search task based on overlapping number patterns. Useful for tracking selective attention, scanning efficiency, and performance under visual clutter and time pressure.
A classic cognitive task measuring interference control. You must identify the ink color of a word while ignoring the word meaning itself. The test reflects selective attention, inhibitory control, and cognitive flexibility.

A more demanding reaction task that combines color-based decisions and sound cues. Useful for tracking speed, accuracy, and response control when simple reaction is no longer enough.
A short visual memory challenge based on remembering patterns in a 3×3 grid. The task measures short-term memory capacity, visual attention, and pattern recall ability.
A quick keyboard performance task focused on typing speed, accuracy, and consistency across a short session. Useful for tracking progress in daily practice and comparing clean performance over time.
A classic visual search task based on overlapping number patterns. Useful for tracking selective attention, scanning efficiency, and performance under visual clutter and time pressure.
A classic cognitive task measuring interference control. You must identify the ink color of a word while ignoring the word meaning itself. The test reflects selective attention, inhibitory control, and cognitive flexibility.
A selective attention task where you must respond to the central stimulus while ignoring surrounding distractors. Performance reflects attention control, resistance to interference, and response consistency.
A response inhibition task that measures how effectively you can stop an already prepared action. Useful for tracking impulse control, timing, and consistency under pressure.
A continuous working memory task where you compare the current item with one shown two steps earlier. Useful for tracking updating ability, sustained attention, and mental workload tolerance.
A task-switching challenge focused on how efficiently you shift between changing rules. Useful for tracking cognitive flexibility, mental switching speed, and stability under pressure.
A demanding dual-task challenge combining symbol-digit matching with quick mental updating. Useful for tracking processing speed, working memory, and resistance to distraction.
A visual filtering task that measures how efficiently you detect relevant signals among distracting noise. Useful for tracking selective attention, search speed, and resistance to visual clutter.
Tracks how accurately you locate a target under spatial uncertainty. Useful for measuring precision, directional bias, and consistency across repeated attempts.
Best tested with headphones at low volume. Move slowly across frequencies and stop if anything feels uncomfortable.
Each round increases the number length. Your score is the longest correctly remembered sequence.
Global Mind Tests brings research-inspired cognitive tasks to your browser. Each test is based on a well-established experimental paradigm from cognitive science and adapted for short, practical self-tracking.
Instead of long questionnaires or abstract scores, you interact directly with tasks that probe attention, reaction speed, working memory and cognitive control. The interface stays minimal on purpose, so performance reflects your decisions, not distractions or interpretation.
The platform builds on decades of research in experimental psychology and neuroscience. Classic laboratory paradigms are translated into browser-based tasks with controlled stimuli, consistent rules and repeatable measurement.
While individual tests differ in structure and difficulty, they share the same foundations: clearly defined cognitive demands, objective response criteria and metrics designed to capture performance over repeated sessions.
If you want to explore the scientific background, start with broad, reputable sources:
Each test focuses on a specific cognitive process and presents a controlled sequence of stimuli that requires fast, accurate decisions. The structure is intentionally simple so that results reflect cognitive performance, not learning complex rules.
Most tasks consist of multiple trials. Individual responses can vary, so results are derived from aggregated performance rather than single actions. This makes comparisons over time more meaningful and reduces random noise.
Results are designed to be easy to read and comparable across time. Each test uses a scoring system tailored to its cognitive demands, so performance can be interpreted consistently without technical details.
Percentiles show how your result compares to a broad reference distribution. A higher percentile means your performance is above the average level observed across a large, mixed population of users, while lower percentiles indicate results closer to or below the typical range.
To reduce random fluctuations, scores are based on aggregated performance rather than single responses. This makes trends across repeated sessions more informative than any one attempt.
Global Mind Tests is grounded in decades of research from cognitive science and experimental psychology. The tasks are inspired by well-established laboratory paradigms that have been widely studied and documented in scientific literature.
Each test is designed with consistency and repeatability in mind, so results can be meaningfully compared over time under similar conditions.
What we do not do: we do not diagnose medical or psychological conditions, we do not prescribe treatment, and we do not replace professional evaluation.
How to interpret results: treat single sessions as a snapshot. Look for trends across repeated sessions and compare results under similar conditions (same device, similar environment).

All results are stored locally in your browser. No data is transmitted to external servers, and no one has access to your results except you on your own device.
Students, gamers, professionals, or anyone curious about attention, speed and working memory. Use the tests to monitor your training, warm up your focus, or just learn how your mind responds under pressure.
