Document Summary
Procedural: how, practice, repetition, it"s implicit you often can"t reflect on it, it"s just acquired, hard to extinguish, example: piano playing (motor movements in general). Declarative: facts, events, acquire with organization, easily forgotten, semantic. Not referenced to own experiences: episodic. Cohen & corkin (1982): compared normals vs. amnesics (like h. m. ), task: tower of hanoi puzzle. , objective: Move entire set of disks to another rod. Only one disk can be moved at a time. Disks must be moved onto another rod. No disk may be place on top of a smaller disk: results: Hm (henry molaison: retrieval of information from ltm intact, stm (working memory) intact, but, could not transfer new declarative information to ltm. i. e. explicit storage of new information a problem. Semantic memory uses different brain processes than episodic memory: episodic memory: hippocampus and anterior prefrontal cortex, semantic knowledge: lateral temporal lobes, posterior prefrontal cortex.
