Document Summary
Memory is a set of 3 complimentary operations: encoding is taking information and putting it into a way that you can understand. You usually encode things that are important or distinct more strongly: storage is both limitless and limited. You could just remember most quotes from your favourite show, but when you"re studying for a test, you have a hard time remembering: retrieval is when you go into your storage memory and retrieve information. You can think of memory as a type of structure: sensory memory, short-term memory, long-term memory. Attkinson and shiffrin"s modal model of memory. Input comes into your sensory memory and gets interpreted: some of it goes into short-term memory. When you get information in your sensory memory, it is really quick and brief. The representation in your mind lasts a little longer than the actual physical stimulus. It"s really hard to test the sensory memories - for example, there isn"t a unit of taste.
