Dual-coding theory postulates that both sensory imagery and verbal information is used to represent information. [ 3 ] [ 4 ] Imagery and verbal information are processed differently and along distinct channels in the human mind, creating separate representations for information processed in each channel.
Allan Paivio's dual-coding theory is a basis of picture superiority effect. Paivio claims that pictures have advantages over words with regards to coding and retrieval of stored memory because pictures are coded more easily and can be retrieved from symbolic mode, while the dual coding process using words is more difficult for both coding and retrieval.
According to Paivio’s dual -coding theory, concrete concepts are the one that is remembered easier from their perceptual memory codes. [6] Evidence has shown that when words are heard they are associated with a concrete concept and are re-enact any previous interaction with the word within the sensorimotor system. [ 7 ]

Multiple code theory (MCT) is a theory that conceives of the human brain as processing information in three codes. A certain issue can be coded in three languages, via symbolic verbal information (letters), symbolic nonverbal information (images), and pre-symbolic information (body feeling).
The "dual coding theory (DCT)" [15] contrasts multiple and common coding theories. DCT is "an internalized nonverbal system that directly represents the perceptual properties and affordances of nonverbal objects and events, and an internalized verbal system that deals directly with linguistic stimuli and responses". [15]
Levels of processing: One of the first alternatives to the stage theory was developed by Fergus I. M. Craik and Robert S. Lockhart (1972). The levels of processing theory holds that memory is not three-staged, which distinguishes it from the stage theory model. Dual-coding theory: Another theory is Allan Paivio’s work in dual coding. This ...
A self-dual code is one which is its own dual. This implies that n is even and dim C = n /2. If a self-dual code is such that each codeword's weight is a multiple of some constant c > 1 {\displaystyle c>1} , then it is of one of the following four types: [ 1 ]
