1.     Encoding
u  The first stage is called encoding and it is how we lay down the foundation to remember information .it is the process of perceiving and processing information so that it becomes a memory.
u  We use visual and auditory stimuli in order to encode information.
u  Attention is important in this stage because it is essential for encoding information that will become a memory.
u  structural encoding, phonemic encoding, semantic encoding.
2.     Storage
u  Storage is the process of retaining information in brain whether in sensory memory the short-term memory and long-term memory.
u  This process of consolidation the stabilize of a memory trace after its initial acquisition is treated in more detail in a separate section.
u  The stage is storage which is the storing of encoding information over time .
u  Storage is essentially retaining information so that it can be used later.
u  We have both long term and working memory that we use for storage of memories.
3.     Retrieval
u  The final stage is retrieval and that is when we access the encoded memory in order to call the information.
u  Retrieval, recall or recollection (calling back the stored information is response to some cue for use in a process or activity)

u  Refers to the subsequent re-accessing of events or information from the past which have been previously encoded and stored in brain.
