Dual Coding
Pairing words with visuals gives memory two routes instead of one.
Evidence: well established. We label every concept honestly, and say so when it's a teaching model. How we rate evidence.
Shrink Definition
Dual coding is the principle that we learn and remember better when information is presented in both words and images rather than words alone. Verbal and visual channels store information in different ways, so combining them gives two routes to recall. Good diagrams paired with clear explanation outperform either alone. It's a practical rule for studying and teaching.
Plain language
We learn better when information comes as both words and images.
Shrink Insight
Two channels, verbal and visual, remember more than one.
Why it matters
It improves studying and teaching by combining words and visuals. It gives a simple, evidence-based way to strengthen learning.
Common misunderstanding
People think reading or hearing words is enough to learn well. Adding relevant visuals to words improves understanding and recall.
Shrink Perspective
Show it and say it, and it sticks better.
Shrink Reflection
What idea would stick better if I drew it?
Shrink Step
Pair a concept you're learning with a simple diagram or image.
Shrink Minute
Sketch a quick picture of one idea you want to remember.
Shrink Takeaway
Words plus pictures beat words alone.
Medical boundary
This concept is educational and shouldn't be used to self-diagnose. It doesn't replace care from a licensed clinician. Symptoms, medication, and treatment decisions should be discussed with a qualified professional, and emergency symptoms require emergency care.
Evidence summary
A well-supported principle in learning and memory research.
