Lecture 10Chapter 7 Remembering Complex EventsLecture OutlineAvoiding Memory ErrorsAutobiographical MemoryAvoiding Memory ErrorsOther studies have demonstrated cases in which memories were surprisingly accurateWhat factors determine whether a memory will be accurate or subject to errorsAvoiding Memory ErrorsA major factor is the retention intervalthe amount of time that elapsed between initial learning and subsequent retrievalWith an increased retention interval more of the original event is forgotten and has to be reconstructed with schematic knowledgeThis creates problems of source monitoringwhich parts of the memory actually occurred and which parts are associated knowledgeAvoiding Memory ErrorsThree hypotheses for why memories weaken with timeDecaymemories may fade or erode activation level Interferencenewer learning may disrupt older memoriesRetrieval Failurethe memory is intact but cannot be accessedThere is some truth to all three hypothesesAvoiding Memory ErrorsAs an example of interference Baddeley and Hitch 1977 found that the number of intervening games and not the passage of time predicted whether rugby players remembered their teammates namesAvoiding Memory ErrorsA concept related to interference is destructive updatingwhen new learning on a topic replaces old knowledge in memory so that the old information is destroyed by newer inputHave to relearn a producer with new elements Avoiding Memory ErrorsContrary to popular belief hypnosis does not help people recover lost memoriesHypnosis does make people more open to suggestion and more vulnerable to misinformation effectsAvoiding Memory ErrorsInstead the method of recovering lost memories that is the most grounded in research is to provide a diverse set of retrieval cuesThis is because at least some forgetting is the result of retrieval failure and this kind of forgetting can be undoneHowever these techniques cannot help someone recall details that were not noticed in the first placeAvoiding Memory Errors
