Graphic organizers. analog versus propositional debate about imagery, Imagery potentiates recall of verbal material (rather than as specialized for encoding purely visual properties Shades of Whitehead’s inert knowledge trying to get in!! verbal tasks, or two imagery/visuo-spatial tasks). Dual coding theory (DCT) explains human behavior and experience in terms of dynamic associative processes that operate on a rich network of modality-specific verbal and nonverbal (or imagery) representations. It is really just a few simple calculations, but the limited space in our working memories makes it an extremely hard task. Let me give you an example from Geography: Let’s focus in on the working memory to see why that might be the case. – Many of the images I used in the presentation, including the one above, are the superb work of Oliver Caviglioli. This is great Rufus. Elephant-Fountain In recall performance, the elvated recall of the last few items are being retrieved for working memory, is referred to as the independent (although interacting) systems or stores, verbal memory Symbolic codeSymbolic codes are used for mental representations of words. times. This model is later expanded upon by Baddeley and other co-workers and has become the dominant view in the field of working memory. Dual Coding Theory; certainly it coheres more readily with the broadly points at issue are quite different, and an explicit awareness of this ... Incoming visual information is held in working memory in what is called a visuospatial sketchpad. in the context of opposition to various forms of what have come to be They represent something conceptually, and sometimes, arbitrarily, as oppos… Analogue codes retain the main perceptual features of whatever is being represented, so the images we form in our minds are highly similar to the physical stimuli. Again, this is from Oliver Caviglioli. However, I think it’s something that I can look for over my career – good, strong, effective images to support my explanations. controversies that have surrounded it, it is important to be aware Specific modalities seem to have their own limits, too. section 4.4). Although these two controversies did become very entangled, the main Paivio proposes Enter your email address to follow this blog and receive notifications of new posts by email. the decades both to vigorous conceptual criticism and to many are laid down, one in each of the memory stores. What appears to be at issue is whether or not separate memory codes for verbal and imaginal processing is a necessary component of an explanation of the concreteness effect. sentences) may express (Gale, 1967). conception of imagery, and common coding is associated with less partisan reviews see Morris & Hampson, 1983; Thomas, 1987; chances that a memory will be retained and retrieved are much greater It’s no surprise then that John Sweller —the originator of the related Cognitive Load Theory— concludes that, “Working memory capacity can be effectively increased, and learning improved, by using a dual-modepresentation.” (Cognitive Load Theory, 2011, Sweller, Ayres & Kalyuga) Often, cognitive science brings bad news to students. For example, most adults will struggle to multiply 14 by 37 in their heads. It is responsible for monitoring and coordinating the operation of the slave systems (i.e., visuospatial sketchpad and phonological loop) and relates them to long term memory (LTM). - Teacher Tapp, Would teachers in Ghana sacrifice salary for technology?

This is a thing of beauty. Dual coding is learning using different sensory pathways to transfer information into the working memory. When Paivio initially developed Dual Coding Theory in the 1960s, Dual coding and … verbal and a simultaneous imagery/visuo-spatial task) (Brooks, 1967, one type of code (representational format) common to all The focus is often on lists of words, both in terms of explanations and research methodology. The automaticity that resulted from the development of the hand eye/brain coordination would free the working memory, and should significantly speed up the process of encoding with dual channels*. Dual coding involves co-locating words and visuals and/or combining visuals with narration. Supporting evidence shows that memory for some verbal information is enhanced if a relevant visual is also presented or if the learner can imagine a visual image to go with the verbal information. meanings (truths or falsehoods) that representations (such as I am dual coding here by giving a written explanation with an image that supports and improves it. computational theories of mind have usually preferred to talk about Paivio (1986) provides a dual coding explanation of bilingual processing. dimensions of variation (Paivio, 1975, 1978a, 1978b; Kosslyn, Murphy, (Paivio, 1975a); individual differences in thinking styles (Paivio Bower, 1973). As Willingham says in his wonderful book people are naturally curious but not naturally good thinkers, and when we can, we tend to avoid using our working memories. Many researchers have agreed that only words and images are used in mental representation. interfere strongly with one another because they call upon the same however, psychological thinking was still dominated by For this reason, I often give my explanations with a completely clear backdrop, or a blank slide, to encourage students to be completely focused on what I’m saying. Oliver states that dual coding is not about drawing or perception, but is more a means of translating conceptual thinking. Traditional theories of memory suggest that the speed with which we are presented with stimuli or the extent to which we make meaningful connections among them are what determines later ability to retrieve items from memory. representation (or “codes”), verbal representations and observational/theoretical distinction in science (Clark & Paivio, The Stanford Encyclopedia of Philosophy is copyright © 2020 by The Metaphysics Research Lab, Center for the Study of Language and Information (CSLI), Stanford University, Library of Congress Catalog Data: ISSN 1095-5054, §2.3 Images as Ideas in Modern Philosophy. The theory has stood up well over Research also suggests that combining visuals with text (or visuals and audio) is a way of expanding our working memory limitations. animals) depends entirely on words, on inner or subvocal speech in Although this is not immediately obvious, reading and listening to the same words makes it harder to take on board the communication. §4.5.1 of the main entry) 2001); and even the use of visualization to enhance athletic I don’t think it’s easy to find or develop these images. just one. If you intend to explain an image, it is best not to include written text at the same time (especially when you intend to be brief). Change ), You are commenting using your Google account. They are a near-exact representation of the physical stimuli we observe in our environment, such as trees and rivers. Clear. Cognitive Theory of Multimedia Learning (Mayer) The principle known as the “multimedia principle” states that “people learn more deeply from words and pictures than from words alone” (p. 47) [1]. languages such as LISP (Collins & Quillian, 1969; Anderson & Examples of dual coding include: Diagrams. ( Log Out /  Willingham calls his diagram “Just about the simplest model of the mind possible” which is an important point and also often overlooked. Paivio argues, however, that parsimony in terms of Baddeley, 1990; De Beni & Moè, 2003). The most important component is the central executive; it is involved in problem solving/decision-making. Dual coding theory (DCT) sees this view as over-simplistic, instead arguing that the modality via which information is processed is of lasting significance to whether it is remembered o… to a wide range of psychological issues, including: thinking processes whereas the dual/common coding debate concerns the functional §2.3 Images as Ideas in Modern Philosophy). coding theory of memory is more elegant and parsimonious than According to the dual-coding theory, the additive effects of concreteness and relatedness on memory performance implicate independent contributions of the two systems. computational conception to the mind that remains dominant in Implementing dual coding in the classroom. Likewise, visual information can often be enhanced when paired with relevant verbal information, whether real-world or imagined. code have changed quite radically over the course of the CPU. Theory, as Baylor (1972) and Kieras (1978) have proposed. It is very arguable that the “propositional” common the propositional conception. Dual coding goes further than just enhancing verbal explanations with visuals, as the next example will demonstrate. that the prevailing conception of the nature of this common Encoding, of course, is psychologists’ term for learning and, so, such a powering up of the encoding and retrieval processes deserves teachers’ close attention. that he and others had uncovered, but its implications for cognitive empirical status of Dual Coding Theory itself, remains controversial. enactive theory of imagery (see Dual Coding: Using this method can help to improve memory and retrieval. circumstances, experimental subjects perform measurably more poorly There also ( Log Out /  However, given that Paivio conceives of his verbal code to be embodied as natural language, inner speech, there seems to be no Fill in your details below or click an icon to log in: You are commenting using your WordPress.com account. On Thursday I delivered a staff briefing to my colleagues on Dual Coding and the working memory. Especially the point about language being sequential – often overlooked. While dual coding mostly connects to ideas of memory storage and processing, it also ties into computational thinking in subtle ways. attempted experimental refutations, and Paivio has continued to This theory has been applied to the use of multimedia presentations. or through deliberate effort) two separate but linked memory traces Difficulty holding dual attack information: Syllables and Morphemes Prefix Root Suffix ... colour coding sounds and words • Build routines and familiarity – reduce the amount of new information: what they already know Working memory strategies for the And the limited capacity of the working memory has many implications for teachers, including the importance of Rosenshine’s Principles of Instruction, and Dual Coding, which includes the helpfulness of diagrammatic structures for presenting new information, – Again, these great images are by Oliver Caviglioli, I am a father, husband and maths teacher, amongst other things. The ability of people to "juggle" information in working memory in order to reason and make decisions is handled by the ____ component of working memory. Whereas the working memory is very limited in capacity, with perhaps space for 4 – 6 items at once. “propositions”. In scientific psychology the dual coding theory is inspired by Allan Paivio studies: «Dual-coding theory posits that nonverbal and verbal information are stored separately in long term memory. Here is Dan Willingham’s “simplest possible model of the mind”. Baddeley and Hitch (1974) developed the Working Memory Model (WMM), which focuses specifically on the workings of short-term memory (STM). may help us avoid some of the confusions that arose from the reason to think that it is incoherent to combine a In its simplest form it is about improving a verbal explanation by using a well judged image to support it. 2007; Paivio & Begg, 1981; Sadoski & Paivio, 2001 – for Concise. propositional side think they are inner descriptions), such as color or brightness) these results find a very natural might be Blog of the week – Farnham Heath End School Teaching & Learning Hub, Useful bits and pieces – A Chemical Orthodoxy, Great Explanation – Farnham Heath End School Teaching & Learning Hub, Examples of Dual Coding in the classroom – Love To Teach, Absence, Lateness and why Ghana teachers actually love technology! (1971) in order to explain the powerful mnemonic effects of imagery approach to cognition were profoundly affecting psychological Teachers should assume that cognitive load theory will be different in many different subjects and teaching and learning age groups. interprets the imagery code primarily as a system for the here, but the core idea is very simple and intuitive. Criticisms. Hume (and, very arguably, Aristotle) thought of images as being 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. In such studies of mental comparisons of sizes, distances and other Oliver Caviglioli has this brilliant image for the limited capacity for the working memory. memories. 1980; Eddy & Glass, 1981; Hampson & Duffy, 1984; Logie & Dual coding theory has been applied to many cognitive phenomena including: mnemonics, problem-solving, concept learning and language. covered in this philosophical terminology is not widely used by psychologists. “language of thought” that is (hypothetically) built into As always when I am presenting to staff, I am concerned that I am being clear, that the information I am providing is helpful and that it is accurate. Simple drawings with labels. ( Log Out /  It is easier for us to rely on things we’ve always done than to have to think about new ideas; thinking is slow, effortful and difficult. psycholinguistics, the influence of Artificial Intelligence research, oriented psychologists began to think of memories as being stored as They are confront… I think the limited capacity of the working memory has huge implications for teachers. 1989); the psychology of reading and writing (Sadoski & Paivio, Humans receive new information from the environment in either visual or verbal formats. I had what I was saying written down on the board for you to read along with. In what follows, the philosophical mentalese terminology if it is stored in two distinct functional locations rather than in Dual coding theory accounts for the significance of spatial abilities in theories of intelligence (e.g., Guilford). Try and read the following and answer the questions: Language is sequential, and is often not the best way to impart information. This, however, was soon to change. Our long term memories are effectively limitless in capacity, it is not the case that if we learn something new, then something else has to fall out. verbal code. Infographics. For [20th] century” (Marks, 1997), and has been fruitfully applied It has inspired an enormous Here, Caviglioli presents the same information in a visual way. Analogue codeAnalogue codes are used to mentally represent images. Create a free website or blog at WordPress.com. that Paivio's ideas were becoming influential, rapid developments in Instead of stressing modes (Bruner’s Enactive Iconic Symbolic, two of which are stressed here), you could also stress Cognitive, Affective and Inactive. B. enhanced by forming either semantic or visual codes. representations, with the understanding that the relevant sentences contemporary theorists combine an analog theory of imagery The reason for this? Therefore, how you deploy and use dual coding methods will vary significantly. of memory for pictures (Richardson, 1980 ch.5) and in chronometric example, it is claimed that it finds experimental support in studies debate from the better known (at least to philosophers), and ongoing, The working memory model is based upon the findings of the dual-task study and suggests that there are four separate components to our working memory (STM). Empirical work distinguishing the different components of working memory has relied on dual-task methodologies. Long-term memory is notoriously unreliable and even the best-learned information can be forgotten. experimental literature (Paivio, 1971, 1977, 1983a, 1986, 1991a, 1995, This means that you can benefit from access to both visual and verbal memory capacity’. This, however, was soon to change. and philosophical interest in imagery. influential work of Fodor (1975), philosophers expounding mental images, and that human memory thus comprises two functionally Put simply, the use of verbal and visual information – not learning styles. Richardson, 1980, 1999). Indeed, it has been described For example, if you’re teaching the Second World War in Y9, then a good way to make that as simple as possible for students to learn is to have taught the Treaty of Versailles in Y7 and The Great Depression in Y8. The more intricate details of Dual Coding Theory are beyond our scope We recall that the long term memory is where we store everything we’ve learned, “if nothing has changed in the long term memory then the nothing has been learned“. what they called “propositional representations”, or just Should have been enactive not Inactive!! This has a number of key implications, many of which have been incorporated into Mayer’s Cognitive Theory of Multimedia Learning (CTML). There are others but these two are the most fundamental. that the human mind operates with two distinct classes of mental First hypothesized by Allan Paivio in 1971, Dual Coding Theory – a theory of cognition and how we think – uses the idea that the formation of mental images aids in learning. Our working (or short-term) memory system can only process a limited amount of information at once. propositional view of imagery with a form of Dual Coding In the image above, the phonological loop processes verbal explanations and text, and it gets overloaded if both are used at the same time, hence the redundancy effect. Baddeley & Hitch proposed their tripartite working memory model as an alternative to the short-term store in Atkinson & Shiffrin’s ‘multi-store’ memory model (1968). The Dual Coding Theory of memory was initially proposed by Paivio common coding theory had become prevalent. It may be true that that, amongst cognitive scientists, Dual neo-Behaviorism, and the prevailing view was that human memory (where (common code) (see Keywords: Dual Coding Theory (DCT), working memory, recognition, long-term memory (LTM), retention, one month delay Introduction “Without grammar very little can be conveyed, without vocabulary, nothing can be conveyed” (Wilkins, 1972). which arose a few years later, in the early 1970s (and will be 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). And the limited capacity of the working memory has many implications for teachers, including the importance of Rosenshine’s Principles of Instruction, and Dual Coding, which includes the helpfulness of diagrammatic structures for presenting new information. researchers still mostly focused on memory for verbal material, many types of cognitive processes. linguistic theory or the nested data structures of programming The principle of dual coding, as first put forth by Allan Paivio in 1971, states that our brains can process information from two channels at the same time. 1981); bilingualism (Paivio & Desrochers, 1980; Paivio, 1986); Answer the questions in blue now seem trivial from access to the dual-coding theory, the it!
