The human mind is truly fascinating and intriguing in terms of how it works and how it perceives the world around us. What is equally captivating is how we manage to store all the information we receive on a daily basis. Whether it's memorizing vocabulary terms for a test, recalling in detail a fond childhood memory, or simply remembering what to buy during a quick errand, all of these things require an operation in the brain and a designated place to store these memories. The comprehensive study of human memory has been a major goal of science and philosophy for thousands of years and has become one of the most important topics of interest in the world of cognitive psychology. But how exactly are memories stored? And above all, how can we strengthen our overall memory? The following explains the stage model of memory theory that is often used to explain the basic structure of how memory works, as well as the cognitive training that can actually help improve the way we retain our information . The Atkinson-Shiffrin theory is an idea conceived by Richard Atkinson and Richard Shiffrin in 1968. In this theory, the two professors designed a model of memory that states that human memory has three distinct components. These components are made up of sensory, short-term and long-term memory. Since it only has three components, it is obvious that the Atkinson-Shiffrin model is extremely simplified. For this reason, it has attracted many arguments from psychologists who claim that this model does not provide adequate explanations of short-term memory and long-term memory reserves. For example, many intellectuals have the ability to completely remember specific information and the middle of a sheet of paper... something common that you know. Overall, our memory helps shape our identity and shapes who we are. Whether it's lovingly recalling events from your youth, remembering the lyrics to a particular song, or recalling the formulas from your final algebra exam, memory plays a fundamental role in all aspects of our life. Not only does it give us a sense of identity, but it gives each person a completely unique and ongoing life experience. Although it is easy to illustrate memory as a kind of mental storage locker that continually files away fragments of information until we need it. to remove it, but in reality it is an extraordinarily composite course of action that requires various parts of the mind. Memories can be extremely vivid and last a lifetime, but they are also just as prone to inaccuracies and forgetting..
