Here are two lessons on theories of long term memory, covering the distinctions between episodic, semantic and procedural memories, associated research studies and critical issues. The first has a slideshow on the key concepts, accompanied by a classification task and a comparison table to complete. The second has a slideshow on critical issues and a reading on clinical case studies of episodic, semantic and procedural memories. An irrelevant case has been added to the reading so that the students get practice at deciding whether evidence is relevant to an issue or not. There is also a Socrative quiz on theories of LTM.
