375: Remembering Events






  1. Types of LTM
    1. Declarative
      1. Episodic: events, have time and space component (what, when, and where).
      2. Semantic: facts (lack episodic information).
    2. Nondeclarative
      1. Skills
      2. Conditioned responses
  2. Episodic Memory
    1. There term "memory" is colloquially used to refer to episodic memory
    2. It's capacity seems to be huge, but no limitless.  Why?  How do we know it is not unlimited?
      1. Superior Autobiographical Memory
        1. Told the story about a woman who knew all the events that had happened in her life.
        2. This ability usually kicks in around adolescence 
        3. Not only do they remember autobiographical info but they also remember the emotional impact of the day
    3. What determines what gets into LTM
      1. Important Factors
        1. Thinking about meaning (depth)
        2. Effort/desire to learn
        3. Emotion
        4. Repetition
        5. Congruence
      2. Serial Position Curve
        1. Primacy Effect
          1. As you have more information coming in the new information will interfere with the old information (retroactive interference)
        2. Recency Effect
          1. You remember the last piece of information better
        3. The middle has a big dip
      3. Depth of Processing
        1. The deeper meaning you put into a word you are trying to remember the better you are able to remember it (remember a list of words and one group pays attention to words with "E" or not, and the other group has to pay attention to whether each word is bigger or smaller that a shoebox - the second group does much better)
        2. Depth
          1. thinking about the meaning
        3. Shallow processing
          1. just thinking about physical characteristics
        4. There can be degrees of depth
