Combining words with images improves retention, and the reason has nothing to do with being a visual learner.
The theory
Dual coding theory proposes two functionally independent but interconnected systems for processing information: a verbal system handling language and a nonverbal imagery system handling visual and spatial representations. Information encoded in both systems has two retrieval routes rather than one, which improves the chance of successful recall. Concrete words that readily evoke imagery are better remembered than abstract ones, which the theory explains directly.
The evidence
The multimedia effect - learning better from words and pictures than from words alone - is one of the more robust findings in instructional research. Related findings include the modality effect, where spoken narration paired with visuals outperforms written text paired with visuals because it distributes load across auditory and visual channels rather than overloading the visual one, and the contiguity effect, where placing related text and images close together beats separating them.

See Cognizil PricingWhy this is not learning styles
This is the crucial distinction. Dual coding says everyone benefits from combining verbal and visual encoding. Learning styles theory says individuals should receive instruction matched to their supposed preferred modality. The first is well supported. The second has repeatedly failed testing - studies matching instruction to assessed style have not found the predicted benefit, despite near-universal popular acceptance of the idea. Use both channels for everyone rather than sorting people into types.
Key takeaways
- Dual coding provides two retrieval routes rather than one
- Spoken narration with visuals beats written text with visuals
- The multimedia effect is among the more robust instructional findings
- Learning styles matching has repeatedly failed testing; dual coding has not
