For something to be remembered you have to:
1) See, hear, or touch it
2) Pay attention to it
3) Store it (encode it)-by rehearsing/repeating it
4) Access (get it back out) it when you need it

Example: Your mom tells you to take out the trash and clean your room.
Step 1: You hear what your mother is saying.
Step 2: You pay attention to it (listen and look at her).
Step 3: You think about taking out trash and cleaning your room.
Step 4: You remember what you’ve been told and go do it.
