Unformatted text preview: Memory • Memory: – the capacity to retain and retrieve information • Flashbulb memories: – Dramatic positive or negative memory (Amsterdam plane crash) • Memories for traumatic events are more vivid than ordinary events – Main aspects of trauma remembered – Can distort details (people distort details) – Accuracy fades over time • Flashbulb Memories – People • Personal recollections of 9/11 or Columbine • Cohort differences in flashbulb memories; personal recollections of 9/11 or Columbine – Video: people asked if they remember what they were doing when Kennedy was shot • How to measure memory – Recall: • Ability to retrieve information which has been learned earlier (exams) – Recognition: • Ability to identify previously encountered information (mc in exam; show you 20 faces, which ones do you recognize?) – Relearning: • Effort is saved in having learned something before (final exam – just need to relearn the information) Example • Recall Task – List the names of the eight reindeer that were Rudolph’s friends • Recognition Task: • Correct List: Models of Memory • Information Processing Model: – Memory and mind are like a computer • Encoding: – How to put information in, retain, store, and retrieve • Levels of Processing: – Different levels of processing impact encoding (to work more efficiently/effectively) • Process, encoding, storage, retrieval Structural encoding: (physical structure) only thinking of letters, not words Phonemic encoding: (sound of word) learning the words, what they sound like (can give a definition, but it doesn’t help – don’t know what it means) Semantic encoding: (meaning) how does this definition relate to (?)… • Shallow Processing: • Intermediate Processing: • Deep Processing: Three Box Model of Memory • Sensory Memory • Short Term Memory • Long Term Memory Sensory works on its own, info goes into short-term memory => Sensory Memory • Sensory Memory – Retains for 1-2 seconds – Acts as a holding bin – ~ ½ second in visual subsystem – ~longer in auditory system – Decides if it is worth processing STM • Short Term Memory : – Holds limited amounts of information for up to 20/30 seconds – If you decide to pay attention...
