- Multi-Store Model of Memory
- Sensory Memory (SM)
- Gathers info from senses (eyes, ears, nose, fingers etc)
- Majority of info gets no attention
- Modality specific encoding (echoic for sound etc)
- Transfers to the STM if it cathces our attention
- Modality specific encoding (echoic for sound etc)
- Majority of info gets no attention
- Very breif time period (250ms)
- Small capacity (4-5 items)-Sperling
- Very breif time period (250ms)
- Short Term Memory (STM)
- Hold information currently being used
- Info fragile from phonetic format in SM
- A&S blieved:
- Limited capacity=7 chunks (miller)
- limited duration (30 seconds)-Peterson&peterson & Brown
- usually forgotten by decay
- (MAINTENANCE) rehearsal --> LTM
- Long Term Memory (LTM)
- Unlimited capacity and duration (Bahrick)
- Mainly held by meaning (semantically encoded, Baddeley)
- The more info is rehearsed the longer/better it would be rememebered
- Mainly held by meaning (semantically encoded, Baddeley)
- Unlimited capacity and duration (Bahrick)
- Hold information currently being used
- Gathers info from senses (eyes, ears, nose, fingers etc)
- Atkinson & Shiffrin (1968)
- One of the first models of memory and very influencial-led to WMM and LOP
- Linear structure as it consists of 3 structural stores in one direction
- due to processes such as attentional and rehersal

- Empirical support
- Free recall-Glanzer and Cunitz's (1966) serial positioning effect
- MRI Brain scan evidence
- Case Study
- HM
- KF
- CHALLENGE- Clive Wearing
- Reductionist
- Linear processing
- Relies on rehearsal
- Not unitary stores
- WMM
- Not accurate representation of stores
- Methodological issues
- Highly controlled environment
- Lacks mundane realism
- Lack of ecological validity
