Dual Coding Theory proposes that humans process information through two channels: verbal and visual. Allan Paivio developed this theory in the 1970s to explain how we encode and retrieve information in these two different ways. According to the theory, we process visual information like images and pictures differently than linguistic information from speeches, writing, or words. The theory also describes three ways we can process information: representational, referential, and associative. Classroom implications include teachers using lectures along with visuals like pictures, videos, and PowerPoint presentations to maximize student learning by engaging both verbal and visual channels.
