P 355, Miyamoto, Winter '09 4 Episodic versus Semantic Memory – Some Examples "I remember parking my car this morning." "I remember the big earthquake in 1963." "I remember that wolves are bigger than coyotes." "I remember that Olympia is south of Seattle." "I remember Beth's telling me to be at the meeting on Thursday." “I remember that Barack Obama won the 2008 presidental election.“ Subject in a memory experiment says, "I remember seeing the word, 'watermelon' on the list you showed me."

P 355, Miyamoto, Winter '09 5 How Do We Know that Episodic and Semantic Memory Are Different Memory Systems? • Neuropsychological evidence for double dissociations • Semantic memory intact; episodic memory impaired. o Alzheimer's patient with intact semantic memory, severely impaired episodic memory. o Patient KC has injury to hippocampus. Lost his episodic memory, but retains semantic memory. (This “KC” is a different person from the “KC” referred to below.) • Semantic memory impaired; episodic memory intact o KC is a 44 year old Italian woman who had encephalitis. Severely impaired semantic memory, intact episodic memory. • Brain imaging studies support distinction between episodic and semantic memory. Next: Repetition Priming – Implicit Memory

P 355, Miyamoto, Winter '09 6 Repetition Priming: (i) Subject is presented with Stimulus A. (ii) A delay is introduced (could be seconds or hours or days). (iii) Subject is asked to perform a task on the same stimulus A or a similar stimulus A’. • Priming has occurred if the initial presentation of A improves performance on a subsequent stimulus A or A’. (See example of word fragment completion task, next slide). Next: Word Fragment Completion Task
