Episodic Memory

Pattern Recognition Memory Task

Measure old/new visual pattern recognition with procedural non-proprietary stimuli and automated scoring.

Useful for visual recognition-memory protocols, aging studies, and CANTAB-adjacent research batteries.

What this task measures

Measures visual pattern recognition by asking participants to recognize previously studied abstract patterns among novel foils.

Core constructs

  • Visual recognition memory
  • Pattern discrimination
  • Medial-temporal memory
  • Recognition sensitivity

Research fit

  • Visual memory studies
  • Aging and medial-temporal research
  • CANTAB-comparison batteries
  • Recognition-memory endpoints

Paradigm overview

Pattern Recognition Memory presents abstract visual patterns for study and then asks participants to identify whether later patterns are old or new.

The first release ships the immediate-recognition condition. The delayed recognition phase is intentionally deferred until the study orchestrator can schedule a second PRM phase after intervening tasks.

Key scoring outputs

Percent Correct

proportion

Proportion of old/new recognition trials answered correctly.

Higher is better

Hits

count

Previously studied patterns correctly recognized as old.

Higher is better

False Alarms

count

Novel patterns incorrectly endorsed as old.

Lower is better

d-Prime

d'

Signal detection sensitivity for old/new recognition.

Higher is better

Mean Correct RT

ms

Average latency for correct recognition responses.

Lower is better

Research FAQ

Common questions about this online cognitive test

How long does the Pattern Recognition Memory Task take?

About 4 to 5 minutes, as listed in the test library.

What device does a participant need?

Untimed test: runs on desktops and laptops. The browser must be Chrome, Edge, Firefox or Safari.

What scores does it produce?

Percent Correct, Hits, False Alarms, d-Prime and Mean Correct RT. Each session is also marked valid, needs review or invalid, with the reason.

Which settings can a researcher change?

Study items (8 to 24). Settings can be changed on yearly plans; free and pay-as-you-go studies use the standard settings.

Which languages can participants use?

The test's own text is in English. Participant pages can be in Italian on yearly plans, but this test's screens stay in English.

Is this a clinical test?

No. ConductCognition is for research use only. It runs, scores and exports the test; clinical interpretation is outside the platform.
