Scattered Pictures Knowing our own identity is something we often taken for granted, but I have often wondered how I know who I am. How is it that I came to know myself and how did my memory develop? I am also very fascinated with young infants and their memories. How is it that I can look at a photo of myself when I was two and have no recollection of that time period but, then look at a photo of myself at ten and remember every little detail. People have three main types of memory storage: sensory memory, short-term memory and long-term memory. Sensory memory is extremely limited. It lasts maybe one second and then it is gone. This type of memory is often referred to as echoic because it’s as if the memory remains an echo. When we pay attention to something or we become conscious of it-it becomes part of our short-term memory. Short-term memory is what we are immediately aware of at any given moment. Keeping things in our minds for short periods is necessary for thinking and interpreting. This is the memory type often known as working memory. Our short-term memory is also highly limited. Its effects last for 20 seconds and in adults it is limited to about seven items. An example of this type may be to try and remember an important sentence such as “The cat’s name is Sandra”. If we really had to remember this we would maybe say it over and over. This is known as rehearsing . We may try to make a mental link between the two words and that is called elaborating. One other way to try and get this to “stick” would be to organize it with other information that we possess. These are the three most important ways to bring information form our short-term memory to our long-term memory. Long-term memory contains our permanent information about the world. It includes everything we know about ourselves, about other people and about the world around us. It is our “permanent” memory. There are two types of long-term memory which are the implicit and the explicit. The explicit part can be put into words and the implicit part cannot be put into words. Implicit memory is also called non-declarative. It consists of memories that are nonverbalizable, for example, tying our shoes or walking. Also, there are two types of explicit memory, and they seem to involve different parts of the brain.
