Long Term Memory

Psychology, Unit 5

today s objectives
Today’s Objectives
  • Distinguish STM from LTM (capacity, encoding, maintenance etc)
  • Apply the serial position effect to your memory
  • Know the 4 types of LTM and apply them to your LTM
  • Distinguish Explicit from Implicit memories
  • Apply “priming” to your memory
long term memory1
Long Term Memory
  • The portion of memory that is more or less permanent, corresponding to everything that we “know.”
capacity of ltm
Capacity of LTM
  • LTM has a nearly limitless storage capacity
  • LTM can be retained for a lifetime (barring illness, brain injury, or chemical interference)
encoding to ltm
Encoding to LTM
  • In addition to phonological memory and visual/shape based memory, LTM uses:
    • Olfactory: smell related/triggered
    • Verbatim memory: word for word (Pledge, National Anthem, etc)
    • Summaries: main ideas are extracted for understanding
maintaining ltm
Maintaining LTM
  • Rote rehearsal: repeat over and over (only 1 that can work to extend STM too)
  • Elaborative rehearsal: linking new info to familiar LTM
  • Schema: a set of beliefs or expectations based on past experience that allows you to infer about new info

Schema (prior LTM regarding the components of a face) cause us to infer that this is a face, when, in fact, it is simply the word “liar” written in cursive.
serial position effect
Serial Position Effect
  • When asked to remember a list, people tend to remember the beginning best, then the end, but rarely the middle
    • Primacy effect: remembering the 1st items best b/c you have time to rehearse them
    • Recency effect: remembering the last items b/c they are still available from STM
types of ltm
Types of LTM
  • Episodic: personal memories based on events one has experienced
  • Semantic: encyclopedic info (how to spell, who was the 1st president)
  • Procedural: motor skills and habits
  • Emotional: learned responses/feelings- shame, fear, sadness
explicit vs implicit memory
Explicit vs. Implicit Memory
  • Explicit: semantic and episodic; can be readily expressed and retrieved from memory
  • Implicit: procedural and emotional; cannot be readily expressed or retrieved from memory
priming
Priming
  • Helps to distinguish between explicit and implicit memory
  • “buried” Explicit Memory you need priming: hints that help you recognize the answer; ex: it begins with “P”
exit ticket
Exit Ticket
  • Draw a venn diagram on LTM and STM
  • List the 4 types of LTM and provide personal examples for each
  • Describe the difference between explicit and implicit memory
