Dual-coding theory is a theory of cognition that suggests that the mind processes information along two different channels; verbal and nonverbal. It was hypothesized by Allan Paivio of the University of Western Ontario in 1971.
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]
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.
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]
The dual-coding theory was first postulated by Paivio and Desrochers in 1980, and indicates that two systems are responsible for the encoding and retrieval of information from memory. [29] The verbal representational system encodes verbal information, such as words.

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).
Reading is an area that has been extensively studied via the computational model system. The dual-route cascaded model (DRC) was developed to understand the dual-route to reading in humans. [14] Some commonalities between human reading and the DRC model are: [5] Frequently occurring words are read aloud faster than non-frequently occurring words.
