PSYC1101 Lecture Notes - Lecture 7: Anterograde Amnesia, Retrograde Amnesia, Temporal Lobe
Document Summary
Without conscious awareness (unintentional of prior experiences on behaviour) Procedural memory, conditioning, priming (episodic or semantic). Perceptual identi cation (repetition/episodic priming - uses backward masking, performance bene t from prior exposure) and fragment completion (semantic priming - spreading activation; aids reading via pre-activation, guides behaviour. ) Priming: behavioural advantage produced by prior exposure/experience. Caused by; korsakoff"s syndrome (drink alcohol, low food/vitamins), damage to hippocampus or diencephalon (main brain regions), surgical trauma or disease. Medial temporal lobe damage = epilepsy so surgery. Hippocampus removed plus surrounding area (limbic system) Retrograde amnesia = cant remember what happened before trauma (hm had this minorly) Anterograde amnesia = cant form new memories (hm + clive had this) Still had procedural memory and semantic knowledge (dependent on the case), intact stm and working memory (used complex mnemonic strategy/maintenance rehearsal). Memory can return overtime (forgetting = impaired memory access/retrieval). Effects of maintenance rehearsal - craik and watkins (1973); g words.
