Go / No-Go with Auditory Cues

Shapes flash; press Space when you see the "go" shape, hold when you see the "no-go" shape. A tone plays either at the same time (congruent) or opposite (incongruent) — that complicates things.

What makes this one different

Most Go/No-Go apps lump errors together. We split them: commission errors (pressed when you should have held) measure impulsivity; omission errors (failed to press when you should have) measure inattention. Two different cognitive problems, two different numbers.

Error breakdown

Two different kinds of errors mean two different things about your cognition.

COMMISSION ERRORS
0
Pressed when you shouldn't have. Impulsivity signal.
OMISSION ERRORS
0
Failed to press when you should have. Inattention signal.

What problem does it solve?

Go/No-Go is the canonical response-inhibition task. It's used in ADHD research, addiction research, and studies of impulse control. The basic finding is that most people can hold back most of the time, but lapse under time pressure or fatigue.

Who is this for

How to interpret your results

High commission errors, low omission errors = impulsive. Pressing too eagerly.

High omission errors, low commission errors = over-cautious. You're so worried about false alarms you're missing hits.

Both high = task is too hard or you're fatigued. Take a break.

Limitations

  • This is not a diagnostic for ADHD. Clinical Go/No-Go uses EEG and standardized protocols.
  • The shape-color mapping is arbitrary — you'll get better at the mapping over time, but the underlying inhibition signal stabilizes.
  • Browser timing has some jitter. For research-grade data use a dedicated system.

FAQ

What does the tone do?

It occasionally mismatches the shape (a low tone with the go shape, for instance). Most research shows the audio cue has a small effect — we include it so you can see whether audio noise throws you off.

Can I get faster?

Somewhat. Reaction time on Go/No-Go has a measurable ceiling around 250–300 ms for most adults. Don't sacrifice accuracy for speed.

How do I use Go / No-Go with Auditory Cues step by step without mistakes?Follow the order given in the usage section: Press for go stimuli, withhold for no-go. We split commission errors (impulsive false presses) from omission errors (missed responses) and visualize both as separate curves. The step-by-step part matters less than the unit check that sits inside it. Confirm every unit matches the thing you are actually trying to measure before you press calculate - that single check catches more wrong answers than any other habit, and it costs about ten seconds.
What are the common mistakes when using Go / No-Go with Auditory Cues?Most common mistakes come down to four habits: entering 20 when the field expects 0.2 because the field is a percentage; leaving a field blank and accepting the default without checking what it stands for; changing one input and reading a result that was calculated before the change; and quoting the output as an exact figure when the page describes it as a reference estimate. Press calculate again after any edit, and treat the number as a reference point rather than a final answer.
How do I read the result from Go / No-Go with Auditory Cues?Read the final figure first, then come back to this section for the conditions behind it: High commission errors, low omission errors = impulsive. Pressing too eagerly. High omission errors, low commission errors = over-cautious. You're so worried about false alarms you're missing hits. Both high = task is too hard or you're fatigued. Take a break. Keep two things apart: the number itself, which comes from the values you typed, and the assumptions it depends on, which decide whether that number is meaningful. The page sets out what a higher or lower result means for your case, so check that direction as well as the magnitude.
Can I act on the Go / No-Go with Auditory Cues result directly?Treat it as one reference sheet before you decide, rather than as the answer itself: This is not a diagnostic for ADHD. Clinical Go/No-Go uses EEG and standardized protocols. The shape-color mapping is arbitrary — you'll get better at the mapping over time, but the underlying inhibition signal stabilizes. Browser timing has some jitter. For re The output describes a magnitude under the conditions you entered. It does not include what it actually costs to act, what might change while you act, or how the other side behaves. Before you commit, compare the result against reality and note which assumptions do not hold where you are.
