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 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.
Using a somewhat different approach, Allan Paivio has developed a dual-coding theory of information processing. According to this model, cognition involves the coordinated activity of two independent, but connected systems, a nonverbal system and a verbal system that is specialized to deal with language.
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]
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.
Paivio has published approximately two hundred articles and is most known for his dual-coding theory. Dual-coding theory posits that nonverbal and verbal information are stored separately in long term memory. Dual coding theory is complemented by the theory of Alan Baddeley, in which working memory is divided into a visuospatial sketchpad and a ...
In coding theory, the dual code of a linear code. is the linear code defined by = { , =} where , = = is a scalar product. In linear algebra terms, the dual code is the annihilator of C with respect to the bilinear form .
