Examples of blending visual and verbal processes may include:
- Captions and graphics
- Voiceover and screen recording
- Text overlays with demonstrations
- Diagrams with explanations
Dual coding is a strategic method of using media to support text in a manner that deepens understanding.
The dual coding theory helps audiences reduce cognitive load when processing information to better support comprehension. Other benefits include:
- Improved memory retention
- Faster understanding
- Heightened engagement
- Targets different learning styles
Creating content with the dual coding theory in mind better reaches audiences and improves outcomes.
