Dual-coding theory

Dual-coding theory, a theory of cognition, was hypothesized by Allan Paivio of the University of Western Ontario in 1971. In developing this theory, Paivio used the idea that the formation of mental images aids learning. According to Paivio, there are two ways a person could expand on learned material: verbal associations and imagery.

Imagery and verbal information are processed differently and along distinct channels in the human mind, creating separate representations for information processed in each channel.
