Dual Coding Theory (Paivio)

Dual Coding Theory proposes that people process information through two linked systems, a verbal system and a nonverbal (imagery) system. Information coded in both, with connections between them, is easier to remember and retrieve than information coded in only one.

When to Use This Framework

When participants seem unmotivated or disengaged

You need to understand what drives adult learners and how to create conditions for genuine engagement and retention.

When introducing concepts, models or processes that need to be remembered, and when designing slides, handouts and visual templates.

The 5 Steps
Follow this sequence to apply Dual Coding Theory (Paivio)
1

Verbal channel

Present the core idea in clear words, spoken or written. Keep text short so it can be linked to a picture.

2

Nonverbal channel

Add a meaningful visual: diagram, timeline, map, object or concrete image. Decorative images do not count.

3

Referential connection

Explicitly link word and image, for example by labelling a diagram or asking participants to explain a visual aloud.

4

Learner-generated coding

Ask participants to draw, sketch or map the idea themselves and then explain it. Producing both codes strengthens memory.

5

Retrieval from both codes

Later in the session, prompt recall through the image as well as the words, such as redrawing the model from memory.

What You'll Achieve

Taps into intrinsic motivation so participants actually want to participate.

Pair each key concept with a meaningful visual and build in moments where participants draw or map ideas and then talk them through.

Practical Tips
How to get the most out of this framework
  • 1
    Give participants autonomy over how they engage
  • 2
    Connect content to their real challenges
  • 3
    Build confidence through early wins
  • 4
    Create psychological safety for sharing
Best For
  • Concept-heavy content
  • Slide and handout design
  • Visual note-taking and sketching activities
  • Language and vocabulary learning
Key Principles
  • Two linked systems: verbal and nonverbal
  • Concrete, imageable content is remembered better
  • Connections between codes aid recall
  • Meaningful visuals, not decoration
Watch Out For
  • Not the same as learning styles; everyone benefits from both codes, and matching to a preferred style lacks evidence.
  • Abstract concepts are harder to image; use diagrams or concrete examples as anchors.
  • Too many simultaneous visuals and text can overload working memory (see Cognitive Load Theory).

AGES ModelThe AGES model summarises four conditions from memory research that help learning last: Attention, Generation, Emotion and Spacing. It gives designers of workplace learning a short checklist grounded in neuroscience of how memories are formed and recalled.
Cognitive Load TheoryCognitive Load Theory explains learning in terms of the limited capacity of working memory and the unlimited capacity of long-term memory. It distinguishes load caused by the content itself, by poor presentation and by the effort of building understanding, and gives design guidelines to avoid overloading learners.
ARCS Model (Keller)The ARCS model is a framework for designing motivation into instruction, built on four categories: Attention, Relevance, Confidence and Satisfaction. It also offers a systematic process for analysing an audience's motivation and choosing tactics to address gaps.
