Short-term memory & working memory
18 important questions on Short-term memory & working memory
What is the Atkinson-Shiffrin model?
Sensory store with attention --> ST or WM (unrehearsed info lost in 10-15 seconds)
- Maintenance rehearsle to keep information in store
WM can encode to and retrieve from LTM
What did Sperling show about Iconic memory?
Why can't you use an arrow when testing iconic partial reproduction?
Arrow is iconic information so it might override.
Use a sound instead
- Higher grades + faster learning
- Never study anything twice
- 100% sure, 100% understanding
How do you test echoic memory?
What are characteristics of the short-term store (STS)?
- Limited capacity (Miller: 7 +-2 chunks)
- Serial processing (rehearsal) required
What does a Brown-Peterson task show about STS?
The longer the 2nd task --> Worse retrieval
How can you test the difference between decay and interference in STS?
Interference: other information that has to be processed.
Task:16 digit list --> Only 1 number was repeated.
- Time between each number being said: Decay (1 per second or 4 per second)
- Numbers in between first mention & repeat: interference
Conclusions on this task:- Decay had no influence, interference had.
(but they only used 4 subjects)
What is the Suffix effect?
Additional item (suffix): Word zero or sound by buzzer.
Results: Buzzer --> Much higher recency effect than word zero
What stands out in a reproduction task in Amnesia patients?
- Normal recency effect
What are findings of the effect of word characteristics in a recall task?
but: If they are semantically the same (big, great, huge) --> No lower recall percentage
What is the influence of syllables in numbers?
Four vs Quatro
What tests are evidence for the visuo-spatial sketchpad?
- Island task: Takes longer if the point on the island is further away?
What is a visual memory span?
Which block has changed?
Are Humans the smartest when it comes to visualspatial sketchpads?
Theory: Visual information needed if you have to climb and jump quickly in the jungle.
How can you improve working memory?
What is the irrelevant speech effect?
You can study better with no music
What is the phonological similarity effect?
Performance not as bad when the words in the list rhyme,
worse when they are alliterative(share same beginning sound),
worst when both of these are occuring throughout the list.
What is the lexicality effect?
The question on the page originate from the summary of the following study material:
- A unique study and practice tool
- Never study anything twice again
- Get the grades you hope for
- 100% sure, 100% understanding
