Title: Memory


1
Memory
2
Memory
The ability of the mind or of an individual or
organism to retain learned information and
knowledge of past events and experiences and to
retrieve it
  • Organization of experience.what would you do
    without it?

3
Outline
  • Types of Memory
  • Memory Processes
  • Forgetting
  • Memory Distortions
  • Memory Disorders
  • Memory in the brain

4
Types of Memory
  • working (short-term) vs. long-term
  • episodic vs. generic
  • explicit vs. implicit (how to become famous
    overnight, Jacoby)
  • procedural (riding a bike) vs. declarative
    (Lance)

5
Types of Memory
  • Working memory
  • The magic number for digit span, and more.
  • Sets a limit on performance, good thing?
  • loading platform for long term memory

7
Memory Processes
  • How do memories get from loading platform to
    long term?
  • Then, how do they get back?

8
Memory Processes
  • Encoding Storage
  • time spent in working memory? rehearsal?
  • attention and engagement
  • connection to what we already know
  • depth of processing (typeface vs. meaning)

Memory Processes
  • Retrieval
  • memory cues context (Charlie Chaplain and the
    scuba divers)
  • depth of processing, easier to find
  • retrieval failure or memory loss? Or forgetting
    vs. misplacement?
  • Seventh grade classmates

11
Forgetting
  • We are forgetting all the time.
  • Decay-- metabolic processes wear down memory
    traces
  • Displacement-- awake vs. asleep during recall
    interval, interference

Memory Distortions
  • Errors of commission as opposed to errors of
    omission-- unwittingly reconstruct an event based
    on what we think and know
  • Schemas and scripts (professors office)
  • Elizabeth Loftus, studies of eyewitness testimony
  • Recovered memories and controversy
  • Do distortions replace real memories, or just
    interfere with recall?

15
Memory Disorders
  • Two main types of Amenesia
  • Anterograde (forward) Amnesia
  • Retrograde (backwards) Amnesia

16
Memory Disorders
  • Anterograde Amnesia
  • problem forming new memories post-injury/operatio
    n
  • Korsikoffs Syndrome (chronic alcoholics),
    Alzheimers, patients like H.M. with
    hippocampal/thalamus damage
  • can read, write, converse, remember life until
    damage was done

17
H.M.
  • Right now, Im wondering, Have I done or said
    anything amiss? You see, at this moment
    everything lookds clear to me, but what happened
    just before? Thats what worries me. Its like
    waking from a drea I just dont remember.
  • Every day is alone in itself, whatever
    enjoyment Ive had, and whatever sorrow Ive
    had.

18
Memory Disorders
  • Retrograde Amnesia
  • problem loss of memory for some period before
    brain injury
  • ECT and head traumas
  • trace consolidation theory -- memory hasnt had
    time to become firmly established, but... several
    years?
  • sometimes memories do come back gradually

19
Memory Disorders
  • What amnesiacs can do
  • procedural memory tasks (mirror tracing)
  • implicit memory tasks ( _L_P_A_T)
  • behavioral conditioning

20
Memory in the Brain
  • Important brain areas
  • Pre-frontal cortex--retrieval working memory
  • Hippocampus other parts of Thalamus--long-term
    memories
  • Amygdala--emotional events, fear conditioning
  • Occipital Temporal Lobes--visual memories
