  1. Remembering and Forgetting

  2. Remembering • Network Theory • We store ideas in separate categories called nodes • As we make associations, we create links among thousands of nodes • Cognitive map • Personal associations that are followed in order to remember something

  3. Remembering • Network Hierarchy • Arrangement of nodes in a certain order • Top- Abstract information • Animal • Middle- More specific information • Bird or fish • Bottom- concrete information • Blue jay, rooster, shark or guppy

  4. Forgetting • Four major reasons for forgetting • Repression • Poor retrieval cues • Amnesia • Interference

  5. Forgetting • Repression • Emotional process that automatically hides emotionally threatening or anxiety-producing information in the unconscious • Comes out in therapy • Not always correct • Sexual abuse

  6. Forgetting • Poor retrieval cues • Mental reminders that we create by forming vivid mental images or creating associations between new information and information we already know • Amnesia • Loss of memory that may occur after a blow or damage to the brain, after drug use, or after severe psychological stress

  7. Forgetting • Interference • The recall of some particular memory is blocked or prevented by other related memories • Proactive- old info. (learned earlier) blocks or disrupts the remembering of related new info. (learned) later • Retroactive- new info. (learned later) blocks or disrupts the retrieval of related old info. (learned earlier)

  8. Forgetting • Biological Bases of Memory • Cortex- where you store words, facts, or events • Used in both short-term and long-term memory • Amygdala- emotional memories, associations • Hippocampus- transfers short-term into long-term memory • Declarative only

  9. Memorization • Mnemonic devices • Ways to improve encoding and create better retrieval cues by forming vivid associations or images, which improve recall • Method of Loci- creating visual associations between already memorized places and new items to be memorized • Peg Method- associations between number-word rhymes and items to be memorized
