Go / No-Go Test

Green circle = press Space or tap ASAP. Red circle = do not press. Inhibit false alarms while reacting fast.

About This Test

About Go/No-Go

Go/No-Go measures response inhibition: press quickly on Go cues and withhold on No-Go cues. An ~80% Go rate builds a press habit so No-Go trials become the real challenge.

What It Measures

Speeded motor readiness plus inhibitory control—the ability to cancel a prepared action when the cue says stop.

Trial Anatomy

Green (Go): press Space/tap ASAP. Red (No-Go): do nothing. Misses and false alarms both reduce score.

Difficulty

Harder modes add trials and shorten stimulus windows / gaps so decisions stack rapidly.

Score Reading

Count correct trials (Go hits + successful withholds). Also watch Go reaction time—fast but reckless play spikes false alarms.

Where It Shows Up

Impulse control under speed pressure matters in driving, sports, and fast UI work—this is a lab-style drill, not a full clinical battery.

Prepotent Responses

When most trials say Go, your motor system prepares to press by default. No-Go trials measure whether you can cancel that preparation in time—the essence of response inhibition.

Speed Accuracy Tradeoff

Chasing the lowest Go RT usually raises false alarms. Set a personal rule: never press unless the green is clearly confirmed. Slightly slower Go hits with clean withholds produce better overall scores.

Transfer Expectations

Improved inhibition on this task can support better stop-signal habits in games and driving drills, but real-world impulse control also depends on sleep, stress, and context.

Instructions & Mechanics

Quick Setup
1

Setup

  • Choose difficulty.
  • Initialize.
  • Rest a finger near Space without pressing.
2

Respond

  • Press on green.
  • Freeze on red.
  • Prefer a clean withhold over a risky mash.
3

Review

  • Check false-alarm count.
  • If high, bias slightly more cautious on the next run.

Expert Strategies

1Ready, Not Tense

Pre-position the finger; tension causes premature presses.

2Value Withholds

On ambiguous color flashes, not pressing is often safer.

3Rhythm Awareness

After long Go streaks, expect a No-Go—reset urgency.

4Short Quality Sets

Inhibition fatigues; stop when false alarms climb.

Frequently Asked Questions

How is score calculated?

Correct Go hits plus correct No-Go withholds.

What is a false alarm?

Pressing on a No-Go (red) trial.

What is a miss?

Failing to press during a Go window.

Why mostly Go trials?

To build a prepotent response so inhibition is tested.

Is RT shown?

Yes for successful Go hits.

Keyboard?

Spacebar is supported.

Trial counts?

About 20 on Beginner up to ~40 on Professional.

Used in research?

Yes—classic executive-function paradigm.

What hurts most?

False alarms on No-Go and misses on Go.

Hard mode tip?

Commit to color fast; hesitation and impulsivity both rise when windows shrink.
