Some examples from this set of practice questions
1.
Describe the multi-store model of memory.
Answer: The multi store model was proposed by Atkinson and Shifrin in 1968 and consists of three stores: sensory register, short-term memory and long term memory. Information from the environment is initially received by the sensory register. If it is attended to, it is passed from the sensory register to the short-term memory, which has a limited capacity of 7+ or -2 chunks, a duration around 18 seconds and is mainly coded acoustically. Rehearsal is the way that information is transferred from short-term memory to long-term memory. It can also be used to extend the duration of short-term memory. Long-term memory has unlimited capacity, live time duration and is mainly coded semantically. Information has to be passed through short-term memory to get to long-term memory and can only be retrieved from long-term memory by entering short-term memory.
