Benefits of Visuals

I FINALLY found the original study that speaks to the effectiveness of using visuals. 

From Robert E. Horn's book Visual Language, a study by John Sweller of high school students and industrial workers found that:

- Visual language produces better problem solving (45% answers correct on a test using conventional text and separate diagrams vs. 64% answers correct using integrated text and diagrams.)

- Visual language produces higher retention (22% more) and in less time (13% less.)

Additionally, the Wharton School of Business studied visual presentations in a business setting and found that they led to:

- 64% increase in immediate decision making

- a clear preference towards presenters who used visuals

- reduction in meeting time by 24%

- an increase in consensus in groups from 58% without visuals to 79% using visuals

- an increase from 50% of audience members persuaded using verbal presentations to 67% of audience members persuaded using verbal plus visuals

I HIGHLY recommend Horn's book as an encyclopedia of all things related to visual language.
