Dual coding theory has its roots in the practical use of imagery as a memory aid 2500 years ago(Yates, 1966). The theory was first advanced by Allan Paivio of the University of Western Ontario, which suggests human mind create separate representations for information processed and both visual and verbal codes are used to organize incoming information into knowledge that can be acted upon, stored, and retrieved for subsequent use.
Educational implication
For reader:
Beginning readers learn to read concrete words by sight much faster when the words are accompanied by referent pictures than when paired only with their pronunications. Concrete verbal material enhances reading comprehension and recall in children and adults.
Instructing learners to form images during reading further enhances reading comprehension and vocabulary learning. Combining pictures, mental imagery, and verbal elaboration is even more effective in promoting understanding and learning from text by students ranging from grade school to university level.
written composition:
The use of concreteness, imagery, and dual coding makes students' writing more readable and memorable.
