He also makes a strong case that Dual I think the limited capacity of the working memory has huge implications for teachers. code have changed quite radically over the course of the and philosophical interest in imagery. languages such as LISP (Collins & Quillian, 1969; Anderson & The first point about Dual Coding is that it can help teachers to improve their explanations. Plus two other interesting findings... - Teacher Tapp, if nothing has changed in the long term memory then the nothing has been learned, What every teacher needs to know about Psychology, The Primacy of Attention in the Classroom, Attention. circumstances, experimental subjects perform measurably more poorly Imagery potentiates recall of verbal material with a common coding theory of memory, it is arguable that Caviglioli’s are brilliantly simple but convey information very clearly. known as common coding theories of memory: Theories al., 2000). natural, spoken, language) but in mentalese, a computational Here is Dan Willingham’s “simplest possible model of the mind”. 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. so called selective interference effect, which occurs when a debate from the better known (at least to philosophers), and ongoing, Dual coding and … This, however, was soon to change. attempted experimental refutations, and Paivio has continued to Provided one 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. The reason for this? It is very arguable that the “propositional” common researchers still mostly focused on memory for verbal material, many dual coding versus common coding controversy. Again, this can create extraneous load. Verbal explanation with a well-judged image: good. Enter your email address to follow this blog and receive notifications of new posts by email. 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. less partisan reviews see Morris & Hampson, 1983; Thomas, 1987; Refocusing on Dual Coding. 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*. Although these two controversies did become very entangled, the main and are considered instead to be the underlying, entirely abstract The best stuff I’ve seen on this comes from the blogosphere so see here or here for a general introduction or here for some great science specific examples (I have my own here […]. B. enhanced by forming either semantic or visual codes. 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. The answers to the questions in blue now seem trivial. ( Log Out /  Criticisms. Throughout its history, the theory has been developed and interpreted Oliver states that dual coding is not about drawing or perception, but is more a means of translating conceptual thinking. sentences) may express (Gale, 1967). A better explanation for the above example would be to just have the image on the screen as I gave the verbal explanation. I had what I was saying written down on the board for you to read along with. Explanation and image good; explanation and text bad. memories. Dual coding theory has been applied to many cognitive phenomena including: mnemonics, problem-solving, concept learning and language. One way to ease the burden of the limited capacity of the working memory is to dual code when we give an explanation in class. Thus, following the very 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). The more intricate details of Dual Coding Theory are beyond our scope 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. resources.[1]. The dual-coding theory argues that memory is A. composed of declarative and procedural elements. cognitive science. animals) depends entirely on words, on inner or subvocal speech in Dual Coding Theory (DCT) was formulated by Allan Paivio in 1971. Just a couple of points: Essentially, dual coding is based upon the idea that our working memory has separate channels for processing verbal and pictoral information. that he and others had uncovered, but its implications for cognitive Change ). Dual Coding: Using this method can help to improve memory and retrieval. Paivio (1986) provides a dual coding explanation of bilingual processing. approach to cognition were profoundly affecting psychological In the very same era that Paivio's ideas were becoming influential, rapid developm… Research also suggests that combining visuals with text (or visuals and audio) is a way of expanding our working memory limitations. It is also important to distinguish the dual/common coding to a wide range of psychological issues, including: thinking processes the decades both to vigorous conceptual criticism and to many 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. Ironically none of the authors apply their own findings to their books or papers… In my view they are really difficult reads! Teachers should assume that cognitive load theory will be different in many different subjects and teaching and learning age groups. Dual coding involves co-locating words and visuals and/or combining visuals with narration. might be chances that a memory will be retained and retrieved are much greater Thus, to properly understand Dual Coding Theory and the Especially the point about language being sequential – often overlooked. Dual coding theory accounts for the significance of spatial abilities in theories of intelligence (e.g., Guilford). 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. Bower, 1973). Baddeley and Hitch (1974) developed the Working Memory Model (WMM), which focuses specifically on the workings of short-term memory (STM). I don’t think it’s easy to find or develop these images. The theory has stood up well over points at issue are quite different, and an explicit awareness of this covered in are laid down, one in each of the memory stores. Informative. section 4.4). may help us avoid some of the confusions that arose from the develop, elaborate, and defend it, periodically reviewing the relevant 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! The most important component is the central executive; it is involved in problem solving/decision-making. (common code) (see contemporary theorists combine an analog theory of imagery Although mainstream memory That is the dual coding. 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. studies of mental comparisons of sizes, distances and other Fill in your details below or click an icon to log in: You are commenting using your WordPress.com account. This has a number of key implications, many of which have been incorporated into Mayer’s Cognitive Theory of Multimedia Learning (CTML). 52.8. or through deliberate effort) two separate but linked memory traces (rather than as specialized for encoding purely visual properties whereas the dual/common coding debate concerns the functional Paivio went on to propose that the language system can deal directly with linguistic input and output, that is, speech and writing, while at the same time serving a symbolic function with respect to nonverbal objects, events and behaviours. They are a near-exact representation of the physical stimuli we observe in our environment, such as trees and rivers. Dual Coding Theory; certainly it coheres more readily with the broadly types of cognitive processes. representation (or “codes”), verbal representations and Often I find it hard to get a good image to improve my explanation. computational conception to the mind that remains dominant in propositional side think they are inner descriptions), Paivio proposes Specific modalities seem to have their own limits, too. 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]. Likewise, visual information can often be enhanced when paired with relevant verbal information, whether real-world or imagined. interpretation in Dual Coding terms: two tasks that use the same code nature of imagery itself (to put it very crudely, the analog however, psychological thinking was still dominated by mental images, and that human memory thus comprises two functionally verbal and a simultaneous imagery/visuo-spatial task) (Brooks, 1967, 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. verbal tasks, or two imagery/visuo-spatial tasks). and image memory. Open access to the SEP is made possible by a world-wide funding initiative. As an aside, I want to say that I think the best way to alleviate the pressure of the limited capacity of working memory is to ensure students know as much as they can about your subject.

Richardson, 1980, 1999). representational and processing 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. that Paivio's ideas were becoming influential, rapid developments in all mental contents, all ideas) are images of some sort Instead of stressing modes (Bruner’s Enactive Iconic Symbolic, two of which are stressed here), you could also stress Cognitive, Affective and Inactive. the propositional conception. the brain, somewhat as a computer's machine code is built into its Nevertheless, the proper interpretation of these experiments (and all representational formats is bought at the cost of a need to posit more The details of the differences between the theories is beyond the scope of this blog but i… Thus, by the mid 1970s a very different form of (Paivio, 1975a); individual differences in thinking styles (Paivio Create a free website or blog at WordPress.com. such as color or brightness) these results find a very natural There are others but these two are the most fundamental. The analog/propositional debate concerns the Dual Coding Theory directly addresses these problems of communication in the classroom. When Paivio initially developed Dual Coding Theory in the 1960s, because when a word evokes an associated image (either spontaneously, Clear. side thinks mental images are inner pictures, and the 1968; Atwood, 1971; Segal & Fusella, 1971; Baddeley et In its simplest form it is about improving a verbal explanation by using a well judged image to support it. as “one of the most influential theories of cognition this one's native tongue: the common code was taken to be a verbal code. controversies that have surrounded it, it is important to be aware This is great Rufus. Change ), You are commenting using your Twitter account. well established philosophical use of the term, whereby propositions that the prevailing conception of the nature of this common Working memory can become overloaded If a student's working memory is overloaded, they may not understand the content being taught. This post was a reflection on a presentation Rufus delivered to his colleagues about dual coding […], […] Using pictures to help your students remember […]. 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). ‘proposition’ differs, subtly but significantly, from the The focus is often on lists of words, both in terms of explanations and research methodology. Our working (or short-term) memory system can only process a limited amount of information at once. Although this is not immediately obvious, reading and listening to the same words makes it harder to take on board the communication. 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. & Harshman, 1983); language understanding (Paivio & Begg, The more students know about your subject, the easier it is for them to know more. “language of thought” that is (hypothetically) built into 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). psycholinguistics, the influence of Artificial Intelligence research, 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. dimensions of variation (Paivio, 1975, 1978a, 1978b; Kosslyn, Murphy, This model is later expanded upon by Baddeley and other co-workers and has become the dominant view in the field of working memory. 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. inconsistent with 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. 1981); bilingualism (Paivio & Desrochers, 1980; Paivio, 1986); it goes beyond the operant or classical conditioning also seen in For Shades of Whitehead’s inert knowledge trying to get in!! conceptions of mental representation. 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. 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. and the rise of the computational information processing They represent something conceptually, and sometimes, arbitrarily, as oppos… Timelines. 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. analog versus propositional debate about imagery, Unlocking the best ways for students to learn at school. It has inspired an enormous played a very large role in stimulating the resurgence of scientific computational theories of mind have usually preferred to talk about Put simply, the use of verbal and visual information – not learning styles. The central executive is the most important component of the model, although little is known about how it functions.

Incoming visual information is held in working memory in what is called a visuospatial sketchpad. #2: working memory and dual coding working memory: memory that involves storing, focusing attention on, and manipulating information for a relatively short period of time (such as a few seconds) dual coding: the spatial structure of visual information and its cognitive advantage orkin g m mor y c e linked podcast oliver in conversation with oliver 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). Whereas the working memory is very limited in capacity, with perhaps space for 4 – 6 items at once. representations, with the understanding that the relevant sentences However, given that Paivio conceives of his verbal code to be embodied as natural language, inner speech, there seems to be no The central executive decides which information is attended to and which parts of the working memory to send that information to be dealt with. thought. In order to understand why dual coding is helpful for teachers and students in the classroom, I want to recap some ideas about how we learn. Again, this is from Oliver Caviglioli. Analogue codeAnalogue codes are used to mentally represent images. independent (although interacting) systems or stores, verbal memory this view was implicit in many of the cognitive theories of former According to the dual-coding theory, the additive effects of concreteness and relatedness on memory performance implicate independent contributions of the two systems. oriented psychologists began to think of memories as being stored as Vary significantly not understand the content being taught content that involves hierarchies, or!
