Working Memory Findings

Studies using adaptive span tasks show that difficulty personalization doubles effect sizes. Static drills plateau quickly because the brain stops perceiving challenge.

Interference training—holding information while filtering distractions—produces far-transfer benefits into reading comprehension and reasoning tests.

Sleep & Consolidation

Stage N2 spindles and REM density correlate directly with vocabulary retention. Cutting sleep from 8 to 6 hours can erase 30% of the previous day’s learning.

Naps help: a 20-minute nap after studying preserves almost as much material as a full night of sleep, according to German university trials.

Nutrition & Supplementation

Flavonoid-rich foods (berries, dark chocolate) and omega-3 intake both improve memory scores in randomized trials. Creatine also benefits vegetarians by replenishing brain ATP stores.

Supplements are most effective when paired with training—without stimulus, the brain has nothing to consolidate.

Action Steps

Use adaptive drills like BrainGames to keep challenge in the growth zone.

Protect sleep windows

Anchor an 8-hour sleep opportunity and nap after intense study blocks.

Eat for memory

Add flavonoids and omega-3s to meals on training days.
