Short Term Memory

Also called Working Memory

Whatever information is in conscious awareness. Any information that we are remembering or manipulating occurs in STM.

slide13
False Memory

How many of you remembered the word sleep?

(It wasn’t actually on the list)

slide14
Parallel Distributed Processing

Sleep

Blanket

Tired

Nighttime

Slumber

Awake

Party

slide15
Levels of Processing

Structural – Is the word in capital letters ?

Phonemic – Does the word rhyme with “deep”?

Semantic – What does the word mean?

Personal – How does the word relate to you?

slide16
Encoding Tips

Chunking: Try and remember the following string of letters (in order):

XCI AFB IVC RDN AIB MQZ

slide17
Encoding Tips

Chunking: Try and remember the following string of letters (in order):

slide19
Encoding Tips

Imagery

To remember:“Monkey, briefcase, spiral, dentist”

slide20
Encoding Tips

Mnemonics:

Openness

Conscientiousness

Extraversion

Agreeableness

Neuroticism

slide21
State Dependency

The surrounding environment can be used as a cue for memory

slide22
Types of Retrieval

Recall – Coming up with an item from scratch

Recognition – Identifying an item from a list of items

Cue Dependent Recall – Coming up with an item after a hint is given

slide23
Context Dependency

Try and Remember these paired associates

Strawberry – Jam

Boxing – Punch

Rip – Tear

Tennis – Ace

Clock – Wind

Small – Minute

slide25
Context Dependency

Crying – Tear

Fruit – Punch

Picture – Frame

Puppy – Kitten

Monkey – Banana

Traffic – Jam

Jetstream – Wind

Glacier – Snow

Poker – Ace

Hour – Minute

Hiking – Trail

Butter – Knife

slide26
Forgetting

The Decay Theory

Interference Theory:Retroactive Interference Proactive Interference

New replaces old

Old replaces new

slide27
Conclusions

1) Short term memory is limited to ~7 items, but long term memory is unlimited

2) Because of a Parallel Distributed Processing Mechanism, the way to a better memory is adding lots of cues

3) Forgetting is due primarily to interference, when cues are blocked.

Evaluate my Teaching
  • What about my teaching did you dislike
  • What about my teaching did you like
  • What was your favorite lecture
  • What was your least favorite lecture
  • What grade would you give me (A+ -- F)
  • Honestly – were the jokes funny?
