The Atkinson-Shiffrin model is the best-known model of human memory. Describe the flow of information through human memory according to the model, including the basic properties of the different types of memory stores
What will be an ideal response?
Answer: A good answer will include the following key points.
? The Atkinson-Shiffrin model consists of three memory stores and control processes that shift information between them.
? Information from our senses first enters the sensory memory store. Sensory memories are highly accurate but very short lived (no longer than a few seconds).
? If we pay attention to sensory memories, they pass into the short-term memory store (STM).
? STM has a limited capacity (only about 7 chunks of information), and can only hold information for about 1 minute without rehearsal.
? With rehearsal, some information in STM will be encoded into long-term memory (LTM).
? LTM is a memory store that can hold vast amounts of information for extended periods of time, if not permanently. Information in LTM can also be retrieved into STM.
