|
Multi-store model |
Atkinson and Shiffrin (1968) - consists of three memory stores linked by processes. |
|
|
Sensory register |
Info held at senses and corresponding parts of brain. Capacity large. Most info receives no attention - remains for brief duration. |
|
|
Attention |
Focused on sensory store - data transferred to STM. |
|
|
Short-term memory |
Immediate task. Limited duration. Disappears if not rehearsed. Disappears due to displacement of info. Limited capacity. |
|
|
Maintenance rehearsal |
Repetition keeps in STM eventually creates LTM. More rehearsed better remembered. |
|
|
Long-term memory |
Potentially unlimited duration and capacity. |
|
|
Retrieval |
Getting info from LTM involves info passing back through STM. |
|
|
Evaluation - Supporting evidence |
Lab studies - support existence of separate STM and LTM. Beardsley (1997) - pre-frontal cortex active during STM not LTM tasks. |
|
|
Evaluation - Case studies |
Scoville and Milner (1957) - HM's hippocampus removed. Personality and intellect intact - couldn't form new LTMs - remembered things from before surgery. |
|
|
Evaluation - Multi-store model too simple |
WMM divided into qualitatively different stores - kind of memories stored. Maintenance rehearsal - long-term memory storage in semantic memory - doesn't explain long-term episodic. |
|
|
Evaluation - How separate are STM and LTM? |
Logie (1999) - STM relies on LTM - cannot come first (MSM). |
