Paradigm overview

The Corsi Block-Tapping Test measures visuospatial span using a fixed array of nine irregularly positioned blocks. A sequence of blocks lights up one at a time, and the participant reproduces the sequence by clicking the blocks.

Forward Corsi span primarily measures visuospatial short-term memory. The optional backward phase adds a manipulation demand by requiring the sequence in reverse order, making it closer to a visuospatial working-memory endpoint.

Key scoring outputs

Forward Span

score

Longest block sequence correctly recalled in presented order.

Higher is better

Backward Span

score

Longest block sequence correctly recalled in reverse order. Null if backward phase is disabled.

Higher is better

Total Score

score

Forward span plus backward span when both phases are enabled.

Higher is better

Forward Accuracy

proportion

Proportion of forward Corsi trials reproduced correctly.

Higher is better

Backward Accuracy

proportion

Proportion of backward Corsi trials reproduced correctly.

Higher is better

Order Errors

count

Trials where the entered block order did not match the expected sequence.

Lower is better

Research FAQ

Common questions about this online cognitive test

Can I run the Corsi Block-Tapping Test online?

Yes. ConductCognition runs the Corsi Block-Tapping Test in a browser-based participant flow with study setup, automated scoring, and export-ready results.

What does this test measure?

Corsi Block-Tapping Test is used for visuospatial short-term memory, visuospatial working memory, sequential spatial recall 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.
