Paradigm overview

The Go/No-Go task is a foundational measure of response inhibition. Participants are presented with a stream of stimuli: green circles (Go) require a spacebar press, while red circles (No-Go) require withholding the response. The asymmetric ratio (75% Go, 25% No-Go) builds a prepotent response tendency, making inhibition on No-Go trials effortful.

Performance is analyzed through signal detection theory. Hits (correct Go responses) and false alarms (incorrect responses to No-Go stimuli) are used to compute d-prime, a sensitivity index that separates true discriminability from response bias. Commission errors (responding on No-Go trials) specifically index failure of inhibitory control.

The task engages the right inferior frontal gyrus and pre-supplementary motor area, regions critical for response inhibition. It is widely used in clinical populations where impulse control is compromised.

Key scoring outputs

Mean Go RT

Average reaction time on correct Go trials. Reflects processing speed for respond conditions.

Lower is better

Go Accuracy

proportion

Proportion of Go trials with a correct response. Low values suggest inattention.

Higher is better

No-Go Accuracy

proportion

Proportion of No-Go trials correctly withheld. Directly measures inhibitory success.

Higher is better

d-Prime

Signal detection sensitivity: Z(hit rate) - Z(false alarm rate). Separates discriminability from response bias.

Higher is better

Commission Errors

count

Responses on No-Go trials (false alarms). Primary index of inhibitory failure.

Lower is better

Omission Errors

count

Missed responses on Go trials. Indicates lapses in sustained attention.

Lower is better

Research FAQ

Common questions about this online cognitive test

Can I run the Go/No-Go Task online?

Yes. ConductCognition runs the Go/No-Go Task in a browser-based participant flow with study setup, automated scoring, and export-ready results.

What does this test measure?

Go/No-Go Task is used for response inhibition, impulse control, sustained attention research workflows.

What data can researchers export?

Researchers can export scored results, and paid plans support trial-level exports for deeper analysis.

Is this for clinical diagnosis?

ConductCognition is for research use. The platform supports task delivery, scoring, and exports; clinical interpretation remains outside the platform.
