  5. Implicit Memory • Priming • Semantic • Repetition • Propaganda effect

  6. Semantic vs. Episodic Memory • Episodic Memory: • Memories for specific events that you yourself were involved in • Can be placed in a certain time or location • Semantic Memory: • General knowledge base http://abjectchaos.com/wp-content/uploads/2008/05/broken-arm.gif
