What is the benefit of using visuals in a presentation?

Using visuals in a presentation significantly enhances understanding and retention of information. When information is presented alongside visuals, such as charts, graphs, images, or videos, it creates a dual-code theory effect, where the brain processes the information both visually and verbally. This multimodal engagement makes it easier for the audience to comprehend complex concepts, remember key points, and retain the information long after the presentation has concluded.

Visual aids can simplify difficult ideas, making them more accessible, and can also help to illustrate relationships or trends that might be harder to convey through words alone. When learners see the material represented visually, they can often grasp the content more quickly and thoroughly than through verbal explanations alone. Consequently, the use of visuals not only supports the verbal message but also reinforces it, leading to improved recall and a deeper understanding of the topic being presented.
