Lesson 2 – The Multi Store Model of Memory

BATs• Draw the Multi-Store Model of memory (D)• Distinguish between each store in MSM in

terms of duration and capacity (C )• Describe the processes of attention and

rehearsal (D)• Explain how forgetting occurs through

displacement and decay (B/C)

How many objects from Kim’s game

can you remember from

last week?

Kim’s Game

Core Theory – The Multi-Store Model

• In 1968 Atkinson and Shiffrin introduced a model to help explain human memory.

• They suggested that there were 3 memory stores working together

• Short Term Sensory Store (STSS)

• Short Term Memory (STM)

• Long Term Memory (LTM)

• STM and LTM differ in terms of ….

• Capacity –

how much information can be stored

• Duration –

how long something can be stored

• You have 10 seconds to look at this list ..

I T V C B B C G S S C

• Jot down the letters

I T V C B B C G S S CHow many did you get right?

Did you get them in the right order?

Did you spot a system you could use?

ITV CBBC GSSC

These are called

CHUNKS

Capacity• Psychologists have found that STM holds

on average 7 chunks of info

• Some people can only hold up to 5 and others up to 9

• Miller called this..

‘the Magic number 7 +/- 2’

How much do you think we can store in

LTM?

The difference between short-term and long-term memory

• Try the activity to replicate an experiment by Peterson and Peterson in 1959.

• P22 Activity 2.7

• I have some trigrams for you if you can’t create your own.

• You will need a stopwatch – you can use your mobile phones or watches if you like!

Forgetting…

(i) What happens in memory when we run out of time or as time passes?

Information decays (if not rehearsed)

(ii) What happens in memory when we run out of space?

Information is displaced – normally on a ‘first in first out’ basis.

Be Creative!!

• To help you remember the Multi Store Model try one of these tasks …

• Create a 3D model of the MSM

• Role play how the MSM works

• Create a poster or storyboard

• Write a poem, story We will judge them later for Use of key words, how easy

to understand, creativity

Homework

1.Do Activity 2.4 p 19 of your text book

TIP -Try to use all parts of the MSM to describe how you would learn the number from first reading or hearing it to remembering it days after learning it.

Take at least 30 minutes on this

2. Fill in glossary or learn key words learnt today
