Short-term memory is where we: maintain sensory information in an unanalyzed form store permanent memories first receive sensory input think about information and solve problems

Short-term memory is where we maintain sensory information in an analyzed form.

During this short-term period, our brain would process whether the information possess something necessary for us to remember or not. If not, the information would not be stored within the long-term memory. (the mechanism is very similar to computer's RAM)
