Outline and evaluate research related to the features of the short term memory (coding, capacity and duration) (16marks)
There are three key aspects of the short term memory.
- Limited capacity - only about 7 items can be stored at any one time.
- Limited duration - storage is very fragile and information can be lost with distraction of passage of time.
- Encoding - primarily acoustic, even translating visual information into sounds.
You could then go on to talk about the tests that were done to see how much information people could store in the short term memory at one time, as well as how it was found that there was a stage between the sensory register and the long term memory. The functions of the short term memory are also interesting to discuss in an essay.
