Slide Content
  1. Memory and Cognition

    Slide 1 - Memory and Cognition

    • Self Guided Lesson 2
  2. Physiology of Memory

    Slide 2 - Physiology of Memory

    • No such thing as an engram (Lashley, 1950)
    • Instead, memory exists as neural connections
    • Increased learning = increased neural connections
    • Long term potentiation
    • Strengthening of neural transmission
    • Drugs that act as agonists and antagonists for the neurotransmitters (like glutamate) involved in LTP can alter memory formation.
    • These same neurotransmitters can be enhanced naturally by sleep.

  3. Slide 3

    • Emotion and memory
    • Traumatic or emotional experiences enhance memory formation.
    • What Freudian principle does this scientific finding dispute?
  4. Examining Types of Memories

    Slide 4 - Examining Types of Memories

    • Autobiographical memory
    • Flashbulb memory
    • Prospective Memory – when you remember what you need to do in the future.
  5. Flashbulb memories

    Slide 5 - Flashbulb memories

    • Where were you when?
    • Vivid
    • We are highly confident about their accuracy
    • BUT flashbulb memories are highly susceptible to distortion.

  6. Slide 6

    • The Hippocampus
    • Explicit memories are processed here
    • Names
    • Dates
    • Facts
    • events

  7. Slide 7

    • The Cerebellum
    • Formation and storage of implicit memories
    • Skills
    • Also called procedural memory
    • Riding a bike
    • Playing the piano
    • Ice skating
  8. Retrieval – Getting Information Out

    Slide 8 - Retrieval – Getting Information Out

    • Recall – when one must retrieve previously learned information
    • Like a fill in the blank
    • Elderly people lose this first
    • Recognition – when one must identify previously learned information
    • Like multiple choice
    • Elderly people retain this longer
  9. Retrieval Cues

    Slide 9 - Retrieval Cues

    • Memories are like spider webs….interconnected and interwoven
    • We retrieve information the way we encode it.
    • Mnemonic devices
    • Cognitive maps
    • Priming – activation of associated information outside of our awareness
  10. Context effect

    Slide 10 - Context effect

    • Godden and Baddeley – scuba diver experiment
    • Deja vu

  11. Slide 11

    • State – dependent memory
    • Mood congruent memory
    • Rosy retrospective
