A significant amount of research has been carried out in this area. According to the Visual Teaching Alliance, there are the many reasons why the vast majority of us are visual learners.
For example, did you know that the human brain can see images that last for just 13 milliseconds? And our eyes can register 36,000 visual messages per hour? 90% of all information that is transmitted to the brain is visual and visuals are processed 60,000x faster in the brain than text.
