Human Performance Test

Reaction Speed Test

Shapes flash one by one. Click ONLY when the target shape appears — ignore the decoys.

1.Press Start Test and note your target shape.
2.Click the arena only for the target shape.
3.Survive all 20 stimuli; false clicks hurt your score.

Why decoys make this harder than it looks

A plain reaction test measures one thing: how fast you move when told to. This variant adds a decision — is this the target? — before every movement. That choice step typically adds 100–200 ms versus a simple green-light test, and it punishes impulsive clicking through the false-click counter. Psychologists call this a go/no-go task, and it mirrors real situations like braking only for genuine hazards while ignoring roadside movement.

Scientific anatomical diagram illustrating the human reaction time neural pathway from visual retina stimulus through the visual cortex and motor cortex to neuromuscular finger click — **Cognitive Processing Delay:** Decoy targets and shape discrimination require an extra pass through the prefrontal and visual association cortex (~80–150 ms) before motor signals dispatch to the spinal cord.

How to score well without guessing

Say the target shape's name silently before starting — verbal labelling speeds recognition.
Keep your eyes centred on the arena rather than chasing the shape's edges.
Accept missing one target; a false click damages accuracy far more than a slow correct hit.
Stay loose in the shoulders — tension slows the click more than it sharpens attention.
Run the test twice: the first run teaches the rhythm, the second shows your level.

FAQ

Reaction speed FAQ

How is this different from the reaction time test?

Shapes appear one by one — some are decoys. Click ONLY the target shape. Clicking anything else counts as a false click and hurts accuracy.

How many stimuli are there?

Twenty shapes per run, roughly half targets and half decoys, with short random gaps so you cannot predict the rhythm.

What makes a good score?

Fast correct hits plus zero false clicks. An average under 450 ms with 95%+ accuracy is excellent.

Why am I slower here than on the plain reaction test?

The decoy decision adds a recognition step before every click. Expect scores 100–200 ms slower than a simple green-light test — that gap is the decision, not slowness.

Should I click fast and accept false clicks?

No. Accuracy weighs heavily: one false click damages your score more than a slightly slower correct hit helps it.

How many targets appear per run?

Twenty stimuli with roughly half targets and half decoys in random order, so anticipation never helps.
