Spaced Repetition: The Science of Long-Term Memory

Harness the power of cognitive science to transform how you learn vocabulary. Discover why spaced repetition is the most efficient method for building lasting language knowledge.

The Science Behind Spaced Repetition

Spaced repetition leverages the psychological spacing effect, where information is more effectively retained when exposure is spread over increasing intervals rather than massed practice.

🧠 How Memory Works

Initial Learning

Information enters short-term memory with rapid initial decay

First Review

Strengthens neural pathways, slows forgetting rate

Spaced Reviews

Each review at optimal intervals consolidates long-term memory

Optimal Spacing Intervals

⏰ The Goldilocks Principle

Reviews should occur just before you're about to forget - not too early (inefficient) or too late (requires re-learning).

Initial Review

After first exposure

1 day
Second Review

If remembered correctly

3 days
Third Review

Continued success

1 week
Fourth Review

Long-term consolidation

2 weeks
Maintenance

Periodic reinforcement

1+ months

⚡ Dynamic Adjustment

If you remember easily:

  • • Increase next interval by 2-3x
  • • Consider the item well-learned
  • • Move to maintenance schedule

If you forget or struggle:

  • • Reset to shorter intervals
  • • Add contextual cues or mnemonics
  • • Increase exposure frequency

Creating Effective Cards

✅ Good Card Examples

Front:
The weather is _____ today. (sunny/beautiful)
Back:
hermoso/a (note: agrees with 'día' - masculine)
Front:
[Audio: Native speaker saying "¿Cómo está?"]
Back:
How are you? (formal) - Use with strangers/elders

❌ Avoid These Mistakes

Too complex:"Translate this paragraph about economic policy..."
No context:"casa = house" (doesn't show usage)
Multiple answers:"What are all the past tense forms of 'go'?"

Your SRS Implementation Plan

1

Week 1: Setup & Foundation

Choose your SRS tool, create 20 high-quality cards, establish daily routine

2

Week 2-3: Expansion

Add 10-15 new cards daily, refine existing cards, track performance

3

Month 2+: Optimization

Analyze weak areas, adjust intervals, integrate with other learning methods

Build Your Complete System

Combine spaced repetition with other proven techniques for maximum efficiency.
