Memory is the name associated tothe processes and structures that play a part in the storage and consequentialgathering of this data. Memory is extremely significant in the lives of allliving creatures.

It is the most crucial part of the way we learn and adapt to overcomechallenging situations. We would not be able to remember what we did yesterday,what we have done today or what we plan to do tomorrow. The multistoremodel of memory was suggested by Atkinson and Shiffrin (1968) and is astructural model.

They were of the belief that memory was made up of threestores: a sensory register, short-term memory (STM) and long-term memory (LTM).Information is passed between stores in a linear fashion, and has been definedas an information processing model similar to a computer, using aninput, process and output. Informationis picked up by the sense organs and then transported into the sensory memory.If attended to this information enters the short-term memory. Information fromthe short-term memory is transferred to the long-term memory only if thatinformation is repeated.

If maintenance rehearsal does not occur, theninformation is forgotten, and lost from short term memory through the processesof displacement or decay. Sensory memoryis the shortest-term part of memory. It is the first stage of the multi storemodel proposed by Atkinson-Shiffin. It is the capability of retainingimitations of sensory information once the original trigger ends. It acts as abuffer for triggers that are gained through the five senses of seeing, hearing,smelling, tasting and feeling, which are kept accurately, but only for aminiscule amount of time. For example, the ability to see an object andaccurately recall the way it looked despite only seeing it for a second is anexample of sensory memory.Short termmemory is the second stage of the multi store model and has been described asthe Brain’s post-it note.

It is used to store ideas and information for shortamounts of time. For example, to read a sentence, your brain must remember thestart of the sentence until the entire thing has been read and understood.Short-term memory  is the capacity forholding, but not manipulating, a small amount of information in mind in anactive, readily available state for a short period of time.

Long-term memory the last stage of the multi-store memory model andprovides the long-lasting maintaining of information. In theory, the storagespace of long-term memory may be infinite, the primary limitation on recallbeing accessibility as opposed to availability. The memory could last anywherefrom a few minutes to an entire lifetime.  Long term memories are encodedvia semantic information, visual information or audible information.The focus of this investigation is to record the extent of whichchunking improves short term memory.
