Key Performance Factors

🧠

Miller's LawShort-term memory holds 7±2 items on average. Chunking groups items into meaningful units, expanding effective capacity by 50–100%.

🗣️

Phonological LoopVerbal memory relies on subvocal rehearsal. The word-length effect means shorter words are recalled better than longer ones.

😴

Sleep ConsolidationSleep within 12 hours of encoding improves recall by 15–30%. REM sleep specifically enhances spatial and visual pattern memory.

🔗

Dual N-Back TransferN-back training engages the dorsolateral prefrontal cortex. Adaptive protocols show 2–3x larger working memory gains than fixed difficulty.

About These Benchmarks

Population distribution data is derived from CogniArena's aggregated user results for the primary test in this category. Age and professional benchmarks are sourced from published peer-reviewed research. Your percentile ranking shows how your score compares to all CogniArena users — a higher percentile means you outperformed more people. Benchmarks are updated regularly as new data is collected.
