How long does the Pattern Recognition Memory Task take?
About 4 to 5 minutes, as listed in the test library.
Episodic Memory
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.
Free to start: 10 free participants per account, then $0.99 per participant for academic research, or any yearly plan. Preview any test free after you sign up.
Measures visual pattern recognition by asking participants to recognize previously studied abstract patterns among novel foils.
Core constructs
Research fit
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.
