Dual Coding: Combining Words and Images for Better Learning
We’re the team behind BrainRash: a free-forever learning platform where you earn tokens and badges for finishing courses, Brain Flashes, and quizzes across six domains (wellbeing, communication, purpose, and more). We use AI for curriculum, tutoring, and recommendations, and we care about i18n (11 languages), performance, and making learning feel like a game, not a chore. We’re here to share what we’re learning while we build.
Your brain has separate channels for processing verbal and visual information. Dual coding leverages both, creating stronger, more accessible memories.
What Is Dual Coding?
Dual coding theory (Allan Paivio, 1971) proposes that information encoded both verbally and visually is easier to remember than information encoded in just one way.
When you read a word AND see a related image, you create two memory traces that reinforce each other.
Why Dual Coding Works
Two hooks for retrieval: If you can't remember via one channel, the other might work Deeper processing: Creating visuals requires more thinking Multiple associations: Each encoding creates different connections
How to Use Dual Coding
When Taking Notes
- Draw diagrams alongside text
- Create sketches (quality doesn't matter)
- Use visual organization (mind maps, flowcharts)
When Studying
- Visualize concepts as you read
- Create mental images for abstract ideas
- Convert text to diagrams
When Creating Materials
- Combine explanations with relevant images
- Use infographics and charts
- Illustrate processes step-by-step
Examples
Biology: Draw the cell, don't just read about it History: Timeline visualizations, maps Math: Diagrams for word problems Languages: Picture vocabulary, not just translations Chemistry: Draw molecular structures
What Dual Coding Is NOT
Just adding decorative images doesn't help. The visual must:
- Relate directly to the concept
- Add information or clarification
- Require processing, not just passive viewing
Combining with Other Techniques
Dual coding + active recall = Draw diagrams from memory Dual coding + elaboration = Explain what your diagram shows Dual coding + spaced repetition = Review visual notes over time
