Ground abstract concepts in concrete, physical instances
An abstract concept understood only abstractly decays faster than the same concept grounded in a concrete, sensory example.
Key takeaways
- What it is: An abstract concept understood only abstractly decays faster than the same concept grounded in a concrete, sensory example.
- Why it works: Dual coding theory (Paivio, 1971) and levels-of-processing research converge on this: concrete information activates both verbal and imagistic memory systems simultaneously, while abstract information activates primarily the verbal channel. The additional imagistic encoding provides a parallel retrieval route, making concrete memories more retrievable. This is why concrete nouns are remembered better than abstract ones in free recall, and why specific examples are remembered far longer than general principles stated without them.
- Evidence: Backed by randomized trials / meta-analyses.
- Avoid: Learning principles first and examples second, then finding the examples forgettable because the abstraction came first — the brain needs the concrete to anchor the abstract, not the other way around.
Why it works
Dual coding theory (Paivio, 1971) and levels-of-processing research converge on this: concrete information activates both verbal and imagistic memory systems simultaneously, while abstract information activates primarily the verbal channel. The additional imagistic encoding provides a parallel retrieval route, making concrete memories more retrievable. This is why concrete nouns are remembered better than abstract ones in free recall, and why specific examples are remembered far longer than general principles stated without them.
How to do it
- 1For every abstract concept you want to retain, generate or find the most concrete, physical, sensory example you can.
- 2Picture the example in your mind as a specific scene — not a generic illustration.
- 3State the principle using the concrete example first, then move to the abstraction: "When [concrete case], what’s happening is [abstract principle]."
- 4Collect multiple concrete cases before generalizing — the abstraction built from cases is more durable than the abstraction stated first.
What the evidence says
RCT / meta-analysisPaivio’s dual coding theory is well supported: concrete words and concepts are reliably better recalled than abstract ones across experimental paradigms. The concreteness advantage in memory is one of the most consistent findings in verbal learning research.
Honest caveat: Concrete encoding must involve actual imagistic processing — merely stating that something is "like a concrete example" without visualizing it may not engage the dual-coding pathway effectively.

Common mistake
Learning principles first and examples second, then finding the examples forgettable because the abstraction came first — the brain needs the concrete to anchor the abstract, not the other way around.
