    (Sharon) DUAL CODING IN WIKIPEDIA

    "Dual-coding theory, a theory of cognition, was first advanced by Allan Paivio of the University of Western Ontario. The theory postulates that both visual and verbal information are processed differently and along distinct channels with the human mind creating separate representations for information processed in each channel. Both visual and verbal codes for representing information are used to organize incoming information into knowledge that can be acted upon, stored, and retrieved for subsequent use."

    "verbal information is processed differently than imaginal, or visual, information and that verbal information was superior to visual information when sequential order was also required for the memory task" (Paivio, 1969).

    "According to Paivio, mental images are analogue codes, while the verbal representation of words are symbolic codes. Analogue codes represent the physical stimuli we observe in our environment, such as trees and rivers. These codes are a form of knowledge representation that retains the main perceptual features of what is being observed. Symbolic codes, on the other hand, are a form of knowledge representation chosen to represent something arbitrarily, as opposed to perceptually."
