The Memory Quotient

The Science of Measuring Memory
Why a New Coefficient Was Needed: The Birth of MQ

When we first launched our Memory Training App, one question stood out from users: _“Am I getting better?”_ Over time, a second—and perhaps even more important—question began to emerge: _“Is my memory getting weaker?”_ These aren’t just casual curiosities—they’re deeply human concerns, especially in an age of constant digital distraction, cognitive overload, and growing awareness of brain health.

When we started research in this direction , we carefully examined existing memory metrics and scoring systems. Established test are excellent for diagnostics and research but not suitable for helping the user to monitor their progress themselves. That’s why we developed MQ (the Memory Quotient)—a new kind of coefficient designed to quantify memory performance over time. Grounded in established clinical tests like the WAIS-IV and Stanford-Binet digit-span assessments, MQ adds intelligent dynamics: penalties that scale with error severity (1.0–2.0×), and bonuses that reward consistency (+1 point for every three perfect recalls). Unlike a one-time score, MQ adapts to you—your performance, your history, your effort. It doesn’t just show where you are; it shows where you’re going.

The MQ Formula

How Your Score Is Calculated The MQ formula was designed with three goals in mind:

  • Reward progress – You should gain more credit for recalling longer sequences correctly.
  • Penalize inaccuracy – Mistakes matter, especially if you're consistently forgetting multiple digits.
  • Capture consistency – Sustained accuracy is rewarded through streak bonuses.

With these principles, MQ becomes more than just a memory score—it becomes a reflection of your performance quality, difficulty level, and consistency over time.

The current version of the MQ Formula is:

MQ = ((Total Correct - Total Penalties + Streaks) / Total Tests) × 10

The Penalty System we are applying is:

Missed DigitsPenalty MultiplierExample (6-shown)
11.0×Recalled 5 → -1.0
21.5×Recalled 4 → -3.0
3+2.0×Recalled 2 → -8.0
Real-World Example: How MQ is Calculated in Practice

Let’s look at a real-world example of a user completing 5 memory tests in a session. Each test presents a sequence of digits to recall, with increasing difficulty. The MQ formula rewards longer correct recalls, applies penalties for missed digits, and grants streak bonuses for consistency.

  • Test 1: 5-digit sequence → Fully correct
    ✅ +5 points (base score = number of digits)
  • Test 2: 6-digit sequence → Missed 1 digit
    ✅ Base: +6
    ❌ Penalty: 1 missed × 1.0 = -1
    Net: +5
  • Test 3: 6-digit sequence → Fully correct
    ✅ +6 points
    ➤ This is the second correct test in a row (streak building)
  • Test 4: 7-digit sequence → Missed 1 digit
    ✅ Base: +7
    ❌ Penalty: 1 missed × 1.0 = -1
    Net: +6
  • Test 5: 6-digit sequence → Fully correct
    ✅ +6 points
    ➤ This completes a streak of 3 perfect recalls out of 4 recent attempts → +1 bonus point
Final MQ Calculation
  • Total Base Points: 5 + 5 + 6 + 6 + 6 = 28
  • Streak Bonus: +1
  • Total Tests Taken: 5

MQ = ((28 + 1) / 5) × 10 = 58
