Cognitive Tests
Purpose
A suite of neuropsychological tests for objective assessment of cognitive functions: reaction time, attention, working memory, executive control. Enables tracking the impact of sleep, stress, and supplements on cognitive performance.
How It Works
Each subtest is a separate interactive screen with a clear protocol. Stimuli are presented with randomized inter-stimulus intervals (ISI), responses are measured to millisecond precision. Results are automatically calculated and saved as metrics. Motion-free zone — nothing should distract during the test.

Subtests
Simple Reaction Time
Measures baseline reaction time. A stimulus appears — respond as quickly as possible. Normal range 200–300 ms. Elevated values may indicate sleep deprivation, fatigue, or brain fog.
Go/No-Go
Response inhibition test. Press for Go stimuli, withhold for No-Go. Measures accuracy and false alarms. Sensitive to ADHD symptoms and sleep deprivation.
Stroop Test
Classic executive control test. A color word is displayed in a different ink color — name the ink color, ignoring the word. Stroop interference is the time difference between congruent and incongruent trials.
N-Back
Working memory test. Determine whether the current stimulus matches the one from N steps back. d' (d-prime) is the sensitivity measure. Usually 2-back is used. Trainable metric that improves with practice.
