The human mind is truly fascinating and intriguing when it comes to 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 an exam, recalling in detail a cherished childhood memory, or simply remembering what to buy for a quick errand, all of these things require an operation in the brain and a designated place where these memories can be archived. The overall study of human memory has been the focus of science and philosophy for thousands of years and has become one of the most significant topics of interest in the world of cognitive psychology. But how exactly are memories stored? And most importantly, how can we strengthen our general memory? The following will explain the stage model of memory theory that is often used to explain the basic structure of memory functioning and the cognitive training that can actually help improve how we retain our information. The Atkinson-Shiffrin theory is an idea designed by Richard Atkinson and Richard Shiffrin in 1968. In this theory, the two professors designed a memory model which states that human memory has three separate components. These components consist of sensory, short-term, and long-term memory. Since it has only three components, it is evident that the Atkinson-Shiffrin model is greatly simplified. For this reason, it has attracted many arguments from psychologists who state that this model does not provide adequate explanations for short-term memory and long-term memory stores. For example, many intellectuals have the ability to completely remember accurate information and… in the middle of a sheet of paper… a common object that you are familiar with). Overall, our memory helps us carve our identity and shapes who we are. From lovingly remembering events that happened in your youth, to remembering the lyrics of a particular song, to remembering formulas for your algebra final exam, memory plays a vital role in every single aspect of our lives. Not only does it provide us with a sense of self, but it offers everyone a completely unique and continuous life experience. While it's easy to illustrate memory as a kind of mental cabinet that continually stores bits of information until we need to pull it out, it's actually a remarkably composite course of action that requires various parts of the mind. Memories can be tremendously vibrant and long-lasting, but they are also equally susceptible to inaccuracies and forgetting..
