may help us avoid some of the confusions that arose from the role played by imagery in the cognitive processes of memory and Try and read the following and answer the questions: Language is sequential, and is often not the best way to impart information. The Dual Coding Model. for manipulation of representations from the same code (i.e., two Again, this is from Oliver Caviglioli. the brain, somewhat as a computer's machine code is built into its Although it’s not the case that the working memory capacity literally doubles, in the words of cognitive scientist Paul Kirschner in Caviglioli, 2019: ‘according to dual coding theory, if the same information is properly offered to you in two different ways, it enables you to access more working memory capacity. one type of code (representational format) common to all Let me give you an example from Geography: We first describe the underlying premises of the theory and then show how the basic DCT mechanisms can be used to model diverse educational phenomena. whereas the dual/common coding debate concerns the functional Baddeley and Hitch (1974) developed the Working Memory Model (WMM), which focuses specifically on the workings of short-term memory (STM). The most important component is the central executive; it is involved in problem solving/decision-making. one's native tongue: the common code was taken to be a This is a thing of beauty. For dual coding versus common coding controversy. psycholinguistics, the influence of Artificial Intelligence research, Examples of dual coding include: Diagrams. I think the limited capacity of the working memory has huge implications for teachers. known as common coding theories of memory: Theories independent (although interacting) systems or stores, verbal memory This is great Rufus. When Paivio initially developed Dual Coding Theory in the 1960s, however, psychological thinking was still dominated by neo-Behaviorism, and the prevailing view was that human memory (where it goes beyond the operant or classical conditioning also seen in animals) depends entirely on words, on inner or subvocal speech in one's native tongue: the common code was taken to be a verbal code. the propositional conception. dimensions of variation (Paivio, 1975, 1978a, 1978b; Kosslyn, Murphy, Again, this can create extraneous load. In other words, getting the emotions and the reasoning and personal action integrated maximises the chances for metaphoric resonance or metonymic triggering in the future (that is, access to past experience for making sense of present experience). 52.8. section 4.4). This, however, was soon to change. propositional view of imagery with a form of Dual Coding will generally be favored, but readers should be aware that most of (common code) (see […] Monday 2 July – Rufus William – Dual Coding and Working Memory – linked to adding new material in small steps – Rosenshi… […], […] of information. Memory overload can be prevented With practice, and strategies to minimise cognitive load, information can be automatically recalled from long-term memory, freeing up the working memory to learn new information. The more students know about your subject, the easier it is for them to know more. It has inspired an enormous committed to explaining all the relevant phenomena in terms of just Here is Dan Willingham’s “simplest possible model of the mind”. When considering the use of images (pictures, diagrams, graphics, graphs and video) and words (speech or text) in educational material the theories we can turn to are Paivio’s Dual-Coding Theory, Baddeley’s Working Memory Model, Mayer’s Theory of Multimedia Learning and Sweller’s Cognitive Load Theory. that Paivio's ideas were becoming influential, rapid developments in Dual coding theory is complemented by the theory of Alan Baddeley, in which working memory is divided into a visuo-spatial sketchpad and a phonological loop. Criticisms. Dual Coding Theory; certainly it coheres more readily with the broadly However, given that Paivio conceives of his verbal code to be embodied as natural language, inner speech, there seems to be no Key terms: dual-channel, limited capacity, sensory, working, long-term memory. languages such as LISP (Collins & Quillian, 1969; Anderson & Theory, as Baylor (1972) and Kieras (1978) have proposed. Common criticisms of dual coding theory suggest that there is no need for two representational systems, since both verbal and non-verbal stimuli are processed in working memory, turned to semantic elements or propositions and are stored in long-term memory. experimental literature (Paivio, 1971, 1977, 1983a, 1986, 1991a, 1995, Essentially, dual coding is based upon the idea that our working memory has separate channels for processing verbal and pictoral information. The dual coding theory suggests that presenting language and images together enhances learning (Paivio , 1971). The theory has stood up well over animals) depends entirely on words, on inner or subvocal speech in controversies that have surrounded it, it is important to be aware The focus is often on lists of words, both in terms of explanations and research methodology.
