What is the key idea behind dual coding theory?

The key idea behind dual coding theory is that a blend of verbal and visual information improves memory. This cognitive theory suggests that individuals can store and retrieve information more effectively when it is presented in both verbal and visual formats. When information is represented through language (heard or read) and simultaneously through images, diagrams, or other visual aids, it provides two separate but interconnected pathways for encoding and recalling the material. This dual representation enhances learning by enabling deeper processing and more robust memory retrieval compared to relying on either verbal or visual information alone.

In other options, the emphasis on only verbal information or combining auditory and kinesthetic learning does not fully capture the essence of dual coding theory, which specifically highlights the synergistic effect of using both verbal and visual information. The suggestion to ignore audio and visual information contradicts the principles of dual coding theory, which advocates for their integration to maximize understanding and memory retention.
