Cognitive Performance Tracker Excel — Reaction Time, Working Memory & Attention, With a Composite Score

Track the 3 cognitive domains measured by validated cognitive assessment batteries like Creyos (formerly Cambridge Brain Sciences): reaction time, working memory, and attention/focus. Log your test session results and this spreadsheet calculates a normalized composite score (0-100) combining all three, tracks your trend over time, and analyzes whether sleep the night before actually impacts your performance -- turning "I feel sharper lately" into an actual measured trend.
