Dual coding theory

Dual-coding theory postulates that both visual and verbal information is used to represent information. Visual and verbal data are processed differently and along distinct channels in the human mind, creating separate representations for each channel’s input. The mental codes corresponding to these representations are used to organize incoming information that can be acted upon, stored, and retrieved for subsequent use. Dual-coding theory does not consider the possibility of cognition being mediated by something other than words and images.
