- Discuss what patient case studies have told us about declarative memory
- What they havent told us
- Other methods e.g. FMRI
- Platel (2002)- Music. EM-> medial and superior frontal gyrus and precuneus. SM-> medial and orbital frontal cortex, L angular gyrus and L middle temporal gyrus
- Burianova (2010)- seed areas for EM and SM. L Hippocampus, L Lingual gyrus and R cuadate nucleus
- SPI model- serial encoding, parallel storage, independent retrieval
- Limited exposure: generalisability, dated, not pure damage, not telling us about interactions
- Other methods e.g. FMRI
- What they have told us
- EM linked to hippocampus
- Spiers (2001)- 147 cases of hippocampal amnesia. EM impaired in all
- Vargha- Khadem (1997)- bilateral hippocampal damage in 3 young amnesics
- Tulving (2002)- K.C- bilateral hippocampal lesions. Assymetrical retrograde amnesia- EM impaired
- SM linked to temporal lobes
- De Renzi (1987)- LP. anteromedial TL damage. Impaired SM
- Yasuda et al (1997)- MN. Bilaterial lesions in TL. Impaired SM
- Semantic dementia- degeneration of anterolateral TL.Damage to SM
- Warrington (1974)- 3 patients with diffuse cerebral lesions. Knowledge of objects and words impaired
- The effects of MTL damage
- Verfaellie (2000)- **. Extensive damage to MTL inc. hippocampus, amygdala, entorhinal and perirhinal cortices- unable to acquire new SM
- Verfaellie et al (2000)- P.S. Anxoia with selective hippocampal amnesia- could acquire some new semantic info
- EM linked to hippocampus
- What they havent told us
