Once a memory is created, it must be stored (no matter how briefly). Many experts think are three ways we store memories: first in the sensory stage; then in short-term memory; and ultimately, for some memories, in long-term memory. Because there is no need for us to maintain everything in our brain, the different stages of human memory function as a sort of filter that helps to protect us from the flood of information that we’re confronted with on a daily basis.
The creation of a memory begins with its perception. The registration of information during perception occurs in the brief sensory stage that usually lasts only a fraction of a second. It’s your sensory memory that allows a perception such as a visual pattern, a sound, or a touch to linger for a brief moment after the stimulation is over.
After the first flicker, the sensation is stored in short-term memory. Short-term memory has a fairly limited capacity; it can hold about seven items for no more than 20 or 30 seconds at a time.
Important information is gradually transfered from short-term memory into long-term memory. The more the information is repeated or used, the more likely it is tp eventually end up in long-term memory, or to be “retained”. Unlike sensory and short-term memory, which are limited and decay rapidly, long-term memory can store unlimited amounts of information idenfinitely.
People tend to more easily store material on subjects that they already know something about, since the information has more meaning to them and can be mentally connected to related information that is already stored in their long-term memory. That’s why someone who has an average memory may be able to remember a greater depth of information about one particular subject.
