**The Multi-Store Model of Memory** The multi-store model of memory was one of the first models based upon the structure of memory. It is quite simplistic by today's standards, but it sparked much more research into memory, which helped develop more advanced models. This model basically says that environmental stimuli is processed by sensory memory. If it is deemed important, or one is specifically focusing on it, then it is passed to short-term memory. Information is held in short-term memory for approximately 6-12 seconds. It is then dropped, unless one rehearses it. If one does not believe this, they should try to recall what sentence three of this paragraph says, without looking at it. If the information is rehearsed enough, it is then moved to long-term memory. Theoretically, long-term storage is unlimited. Occasional recollection of the information helps one maintain their grasp on it. The multi-store model of memory was founded by Atkinson and Shiffrin (1968) and is based upon their research. **The Working Memory Model** The working memory model states that everything revolves around the Central Executive (basically short-term memory). Sensory input is put through the phonological loop and the visuo-spatial sketchpad. The phonological loops is basically the voice in your head, and the sketchpad is how you visualize and see things. This model says that all memory processes come together in the central executive, and that the central executive contributes to them as well. It is based upon the research of Baddeley and Hitch (1974)
