Storage is retention of the information, and retrieval is the act of getting information out of storage and into conscious awareness through recall, recognition, and relearning. The idea that information is processed through three memory systems is called the Atkinson-Shiffrin model of memory.

Encoding is the act of getting information into our memory system through automatic or effortful processing. First, environmental stimuli enter our sensory memory for a period of less than a second to a few seconds.

memory — set of processes used to encode, store, and retrieve information over different periods of time. Atkinson-Shiffrin model — memory model that states we process information through three systems: sensory memory, short-term memory, and long-term memory. recognition — identifying previously learned information after encountering it again, usually in response to a cue. retrieval — act of getting information out of long-term memory storage and back into conscious awareness.
