For example, if someone tells you an address but you can't find a pen, you might say the address over and over again in your head until you find the pen. However, there's an important concept here of 'maintenance rehearsal' which is essentially the process repeating information that you know you only need for a short time but might not need later. Most people would argue that by taking the memory test here, you are working within your long term memory. While this is a slightly strange concept, in reality, your brain, rather than you (!) will decide over the course of the test the best way to hold the information required. The images that you see within the test are moved rapidly to VSTM and then to long term memory. It's been noted that as Eidetic memory only tends to exist in younger children and as they aren't likely to be taking this memory test, we'll leave it there ! Iconic Memory and the Memory Testīy now, you should realise that iconic memory plays only a fleeting part in the memory test. For the purposes here let's define it as the ability for someone to clearly recall an image (or the information the image represents, such as a number) even after a few brief moments of viewing. It's not exactly the same and in the instance of this memory test, photographic memory is likely to be more relevant. Iconic Memory and Eidetic MemoryĮidetic memory is often called photographic memory. In short, you must decide whether to keep the images by moving them into Long-Term memory (LTM) or get rid of them. George Miller, an eminent cognitive psychologist calculated that only around seven pieces of information could be held in short term memory. VSTM is essential for a whole range of functions but perhaps strangely, there's not much you can actually store in it. Images that we decide to store are then moved to Visual Short-Term Memory (VSTM) which is generally regarding to last in the region of say half a minute. The first of which is iconic memory which, as we know, lasts a fraction of second. Visual memory can be typically broken into three stages. How Iconic Memory fits into the wider Visual Memory This content is associated with The Open University's Forensic Psychology qualifications. If you like, it's split-second memory storage. 5 minutes Do you have a photographic memory Updated Friday, 19th July 2019 Can you hold an image in your mind by just looking at it for a brief amount of time Try our photographic memory test and see whether you have eidetic memory. It's commonly referred to as ultra-short storage and while it will vary from person to person and situation to situation, it's considered to be in the region of less than half a second. Images stored in iconic memory decay very quickly. However, we can decide, to an extent, which elements of sensory memory we decide to move further into our memory chain. Our sensory memory is not controlled by us - providing our eyes are open we cannot stop an image being seen. Sensory memory is perhaps best considered as a filter, processing the huge amount of images, smells, sounds and physical feelings that we experience all the time. Iconic memory is the name given to how we handle fleeting or temporary visual images.
