REACTION TIME

Reaction Time Test

Measures response latency, variability, vigilance, and inhibition. Includes SRT, CRT, PVT, and go/no-go tasks for focus and performance profiling.

Instant Scoring
Latency, variability (SD/jitter), lapses, and accuracy per task type.
Adaptive Difficulty
Adjusts stimulus rate and choice complexity across SRT/CRT/PVT.
Timed Trials
Optional timers, progress indicators, and rest break recommendations.
Visual Stimuli
SRT/CRT with visual cues, color/shape choices, and distraction control.
Auditory Stimuli
Tone-based SRT/CRT with varied frequencies and response mappings.
Data Protection
Privacy-first storage with encryption, consent, and easy export/delete controls.

PRINCIPLE

What does it measure?

Reaction Time captures response latency and vigilance. Tasks include simple reaction time (respond to a single cue), choice reaction time (map multiple cues to responses), psychomotor vigilance test (sustained attention), and go/no-go inhibition.

Simple Reaction Time (SRT)
Respond to a single stimulus; profile base latency and lapses.
Choice Reaction Time (CRT)
Map multiple stimuli to responses; measure speed-accuracy trade-offs.
Psychomotor Vigilance (PVT)
Sustained attention task tracking lapses and variability over time.
Variability & Jitter
Assess stability via standard deviation and trial-to-trial fluctuations.
Go/No-Go Inhibition
Respond to targets; inhibit responses to non-targets; profile control.
Benchmarks
Compare ranges; premium includes percentile estimates and cautions.
