The three stages of processing are encoding,storing,and retrieving.In the encoding phase,your brain changes information (e.g.,the story you read in a magazine) into a meaningful neural code that it can use.The storage phase is how you maintain the coded representation in a network of neurons in the brain.During this phase,you would maintain the material from when you read it until you take the test,or even longer.In retrieval,you re-access the information.During this phase you would bring to mind a previously encoded and stored memory when it is needed,such as when you need to tell someone about the story you just read.
