Atkinson-Shiffrin Model

The Blog: The evolving field of neuroscience: Where is my memory? by Jenny Rostek explains how the Atkison-Shiffrin model works. The Atkinson-Shiffrin model proposes that human memory involves a sequence of three stages including Sensory Memory (SM), Short-Term Memory(STM), and Long-Term memory(LTM). This model proposes that memory works in a serial process. It also suggests that short term memory can be lost within about 30 seconds unless it is repeated. In this model, working memory can serve as storage for new material, and as a ‘loading platform’ for long-term memory. It follows an information processing setup.  First information enters a sensory register breezily, then it goes through pattern recognition, then it enters short term memory. It an item makes it past short term memory it may make it to long term memory if pattern recognition was able to give enough meaning to it. Not everything is equally weighted. This whole process is why some people learn things easier than others.
