1. Multi-store model of memory Atkinson and Shiffrin (1968). It is a structural model Linear flow Contains 3 separate independent components

2. Environmental stimuli

3. Sensory memory Decay Made up of the 5 senses e.g smell, touch, hear, taste and sight

4. Attention

5. Short-term memory Limited capacity and duration Capacity is 7 plus or minus 2 (Miller 1956) Duration is maximum 20seconds when sub- vocal rehearsal has been blocked (Peterson and Peterson 1959) Prefers to encode acoustically (Baddeley 1966) Decay/Lost

6. Maintenance Rehearsal Retrieval Retrieval takes active information from long term memory back into short term memory If information rehearsed enough, It goes into the long term memory.

7. Long-term memory Unlimited capacity and unlimited duration Duration – is about 48years and possibly higher (Bahrick et al 1975) Prefers to be encoded semantically (meaning) Decay and Displaced
