Q

What is a model?

A

-a visual rep. of how something words
-allows predictions of human behavior to be made
-can ask q’s/provide a’s which can’t be asked/given irl
-can be altered to relate to reality

Q

How many memory stores does it suggest ppl have?

-3 separate/distinct stores
-differ in coding, capacity, duration

Q

How does info pass through each store?

A

-it’s a linear + sequential model, info passes through in order\
-passes from store-store if conditions are met
-SS -> STM = attending to the info

Q

What is the C, C, D of the SS?

A

-coding: modality specific (encoded how it entered)
-capacity: very large
-duration: less than 1/100th of the info reaches the STM (attends to 1/100th of info coming in)

Q

What stores are in the SS?

A

-iconic store: where visual images are kept for a short period (visual encoding)
-echoic store: where auditory senses are kept for a short period (acoustic encoding)
-haptic store: sensory memory retains physical senses of touch + internal muscle tensions (touch encoding)

Q

What did Baddeley’s research find?

A

Performance was worse when additional info is given in the same modality you are storing the info (displaces it)

Q

How does info get lost in the STM?

A

-will decay if not rehearsed
-new info can ‘push out’ old due to limited capacity (displacement)

Q

How does info get recalled from the LTM store?

A

-recalled back to STM
-has to be in STM to process it in the moment

17
Q

What are key points of HM case study?

A

-HM suffered trauma to his hippocampus
-researchers wanted to determine if he could form new memories
-was concluded he couldn’t make LTMs
