Explicit Implicit declarative nondeclarative With conscious recall Without conscious recall Processed in hippocampus Processed by other brain areas including cerebellum Classical conditioning 0 We know about what brain regions are involved in forming new memories from brain imaging studies as well as observations of patients such as HM who had most of his hippocampus removed Facts Personally Skills general knowledge experienced events motor and cognitive lllllllllllllll Retrieval Getting Information Out 0 Retrieval Cues 0 When you encode into memory a target piece of information you associate it with other bits of information about your surroundings mood location etc These bits of information can serve as retrieval cues 0 Putting yourself back in the context where you experienced something can prime memory retrieval awaken associations between what you are trying to recall and your surroundlngs 0 Greater recall when learning and testing contexts were the same 30 20 10 0

something you learned earlier disrupts your recall of something you experience later 0 Retroactive interference occurs When new information makes it harder to recall something you learned earlier Sleep may provide some protection against retroactive interference ll Proactive interference Retroactive interference Early event learn friend s email address at college flerning23mymailedu Can no

which a witness is shown Misinformation and Imagination Effects suspects one at a time instead of all at once The rationale psychologist Gary Wells discovery that when shown sequential lineups Later event Familiar old address interferes with recall of new email address nfleming learn password for using bank debit card my99money The bottom line is that forgetting can occur at any memory stage As we process information we filter alter or lose much of it people make absolute judgments which lead to much lower rates of misidentification The result sequential lineups cut eyewitness misidentification in half compared to simultaneous lineups Fewer innocent people go to jail Broader Implications Chapter Review Sigmund Freud proposed that we repress painful memories to protest our self concept and minimize anxiety People have been accused and sometimes convicted of sexual abuse abused on repressed memories 0 Elizabeth Loftus Research asking question about actually happened and one that had not happened 25 people remembers false event as a real eventThe memory is changeable might been fault can be planted
