PSY 320 Lecture Notes - Lecture 8: Lobectomy, Episodic Memory, Striatum
Document Summary
Procedural memory short term- fractions of second to minutes long- minutes-years learn something for the first time and it has to be consolidated and moved into long term. Stm ltm re-consolidation when you want to do something and access memory once done thinking about memory has to go back into long term storage.
