PSYC2215 Lecture Notes - Lecture 6: Anterograde Amnesia, Indirect Tests Of Memory, Retrograde Amnesia
Document Summary
Lost episodic memory (had anterograde amnesia ie. could not form any new memories). Suggests hypo campus binds episodes together for memory (ie. items, space, time). Had intact digit span - suggests stm separate from ltm. Intact memories from childhood but not from just before the surgery (ribot resident of retrograde amnesia - old memories seem to become hippocampus independent. Episodic memory becomes semantic memory, called semati cation or decontextualisation). Neural transfer via long-term consolidation also possible. His performance on implicit memory tests was preserved. Fragmented picture identi cation, word completion, lexical decision, perceptual identi cation, object priming. Commonality of these tasks - no intention to retrieve from (episodic) memory. Independent experimental variable has an e ect on one but not the other type of test ie. in screenshot of amnesia study, amnesia had a signi cant e ect on implicit but not explicit (direct) tasks.
