Chapter 11 Further Reading: Dual Coding and Visualization

Foundational Research

Paivio, A. (1971). Imagery and Verbal Processes. Holt, Rinehart & Winston. The original theoretical statement of dual coding theory. Dense and technical, but historically important if you want to understand where the idea came from. Paivio built on decades of his own experimental work showing that concrete words (which evoke images) are remembered better than abstract words — an early sign that imagery and verbal processing are distinct systems.

Paivio, A. (1990). Mental Representations: A Dual Coding Approach. Oxford University Press. The expanded, updated version of the theory. More accessible than the 1971 work. Covers the experimental evidence and the theoretical architecture in detail.

Mayer, R. E. (2009). Multimedia Learning (2nd ed.). Cambridge University Press. The essential reference for instructional applications of dual coding. Mayer's principles for effective multimedia — the multimedia effect, the coherence principle, the contiguity principle, the redundancy effect — are grounded in careful experimental work and have direct applications for anyone creating or using educational materials. The most practically useful book in this list.

Accessible Books

Rohde, M. (2013). The Sketchnote Handbook. Peachpit Press. The definitive introduction to sketch-noting as a practice. Mike Rohde develops the technique and provides practical guidance on visual vocabulary, layouts, and workflow. Illustrated throughout (naturally). If you want to build a sketch-noting practice, start here.

Buzan, T. (2006). Mind Mapping: Kick-Start Your Creativity and Transform Your Life. BBC Active. Tony Buzan's mind mapping technique is a specific visual note-taking approach with a large following. The research support for mind mapping specifically is more mixed than for dual coding generally, but Buzan's underlying intuitions about visual organization and radial thinking are worth engaging with. Read critically.

O'Brien, D. (2000). Learn to Remember. Chronicle Books. Written by a former World Memory Champion, this book teaches the method of loci and other mnemonic techniques from the inside — by someone who uses them competitively. More practical and less academic than the research literature, but grounded in genuine expertise.

Foer, J. (2011). Moonwalking with Einstein: The Art and Science of Remembering Everything. Penguin. A science journalist embeds himself in the competitive memory world and trains himself to the US Memory Championship. The best popular account of how memory techniques actually work and what practicing them feels like. Engaging narrative with real cognitive science woven throughout. Essential reading if you want to be motivated to actually try method of loci.

Research Papers

Mayer, R. E., & Moreno, R. (2003). Nine ways to reduce cognitive load in multimedia learning. Educational Psychologist, 38(1), 43–52. A practical synthesis of Mayer's multimedia research, organized around specific design principles. If you're creating learning materials or presentations, this paper tells you exactly what to do and not do.

Piscitelli, A., & Dowd, J. (2019). Evidence-based sketching for learning. CBE — Life Sciences Education, 18(1). A study examining sketch-noting in college biology courses. Moderate-quality evidence but well-designed, with direct relevance to anyone using sketch-noting for science content.

Maguire, E. A., Valentine, E. R., Wilding, J. M., & Kapur, N. (2003). Routes to remembering: The brains behind superior memory. Nature Neuroscience, 6(1), 90–95. A fascinating neuroimaging study of people with superior memory. The finding: they don't have unusual memory capacity — they have unusual spatial navigation skills, because they all use the method of loci. Their brains light up in spatial regions (hippocampus, parahippocampal gyrus) when memorizing. This is neuroscience-level evidence for why the technique works.

Wammes, J. D., Meade, M. E., & Fernandes, M. A. (2016). The drawing effect: Evidence for reliable and robust memory benefits in free recall. The Quarterly Journal of Experimental Psychology, 69(9), 1752–1776. Research on a specific form of dual coding: drawing words rather than writing them. Results are large and consistent. Drawing produces better recall than writing, imagining, or viewing pictures of objects. The "drawing effect" is now a well-replicated finding with implications for anyone who can add sketches to their note-taking.

Online Resources

Learning Scientists — Concrete Examples and Dual Coding posts (learningscientists.org) The Learning Scientists have created downloadable summaries and practical guides for dual coding and other evidence-based strategies. Free, well-designed, and grounded in research. Their "Dual Coding" study guide is particularly useful for seeing the technique applied across different subjects.

Mayer's research lab resources (UC Santa Barbara) Richard Mayer's lab has published hundreds of studies. Many are accessible through Google Scholar for free. If you want to go deeper into multimedia learning research, searching "Richard Mayer multimedia learning" will give you a decade's worth of solid experimental work.
