| Question | Answer |
| Who created the Multi Store Model of Memory? | Atkinson and Shiffrin |
| When was the model theorised? | 1968 |
| What does the Multi Store Model compare the workings of the memory to? | The internal workings of a computer- they cannot be easily altered and work in a set, mechanical way |
| What three stores does the MSM state memory consists of? | The sensory store, short term store and long term store. Also known as sensory, short term and long term memory. |
| What is the purpose of the sensory store? | To act as a buffer for all of the information our senses are bombarded with. It holds this attention for a short period until attention is paid to it. If attention is not paid to it, it will be forgotten. |
| How is sensory memory normally tested? | A grid of letters is flashed onto a screen in front of participant for a brief moment and the participants are asked to recall as many letters as they can. |
| How many letters can participants recall on average from the test for sensory memory? | 4.32 |
| What is the duration of the sensory memory? | A few hundred milliseconds |
| What is the duration of the short term memory? (Short term memory is the step that occurs once sensory information has been paid attention to.) | 15-30 seconds |
| What happens to information in the short term memory after 30 seconds, if we have not paid attention to it? | It is thought to go through decay |
| What did Peterson and Peterson do? | Tested short term memory by giving participants a set of three consonants (eg, BDF) known as a trigram and then stopped their rehearsal by making them count back from a number in threes. |
| What did Peterson and Peterson find? | Correct recall of the three consonants was pretty accurate after a short interval of distraction but if distracted from rehearsal for over 15-18 seconds, correct recall fell rapidly. |
| What is the capacity of the short term memory (According to Atkinson and Shiffren)? | 5-8 items. Miller (1956) later referred to this as the magic number 7 (7 +/-2) |
| What is encoding? | The way in which we remember a piece of information. For example, we don't always remember something we see as a visual memory. We can remember it in auditory form, hearing ourselves saying something such as 'I saw a dog'. |
| How does information get into the long term memory? | Rehearsal from the short term memory |
| What is the duration of the long term memory? | Potentially, long term memories can last a lifetime. It can also have a potentially limitless capacity. |
| Summarise the encoding, duration and capacity of each type of memory store in the MSM |
