Final answer:
The Atkinson-Shiffrin memory model defines three stages of memory: sensory memory, short-term memory, and long-term memory. Chunking, rehearsal, and attention are important factors in the processing and storage of information in these memory stages.
Step-by-step explanation:
The Atkinson-Shiffrin memory model defines three stages of memory: sensory memory, short-term memory, and long-term memory. In this model, information enters the sensory memory stage first, where brief sensory events, such as sights and sounds, are stored for a short period of time. Then, if the information captures a person's attention, it moves into the short-term memory stage. Chunking, which is organizing information into manageable bits or chunks, can increase the capacity of short-term memory. Lastly, if the information is rehearsed or processed further, it can be transferred to long-term memory for permanent storage. Once in long-term memory, the length of time the information stays there can vary.
