(28 cards)
What is working memory
Collection of structures and processes used for temporarily storing and manipulating information
Where is acoustic information stored
Left hemisphere (Broca’s and Wernicke’s area)
Where is visual/spatial information stored
Right hemisphere (in visual cortex)
What is anterograde amnesia
Inability to form new memories which were formed after the brain injury
What is retrograde amnesia
Deficit in recall and recognition of facts and events experienced before the onset of brain damage
Where is procedural memory stored
Cerebellum
How can items enter long term memory
Only via short term memory according to the modal model
Where is procedural memory associated with
cerebellum
What damage did HM have
Medial temporal damage
What is working memory like in medial frontal lobe damage
Intact working memory
Normal digit span
Can remember numbers unless interrupted
What is procedural memory like with medial frontal damage
Intact procedural memory: can learn new motor tasks or can perform well on tasks such as
- Moving object with a stylus
- Drawing an image by tracing it on a mirror
What is episodic and semantic memory like for medial frontal lobe damage
Anterograde amnesia for it
- cant recognise people just met
- Difficulty with spatial orientation
- Can copy figures but couldn’t recall it from visual memory
What is working memory like in medial temporal and frontal lobe damage
Impaired
Can process information for about 7 to 30 s in working memory on neuropsychological tasks
What is ability to form new procedural memories like in medial temporal and frontal lobe damage
Intact
What is episodic, and semantic memory like in medial temporal and frontal lobe damage
Unable to store new memories and can only remember very few facts from past so shows both anterograde and retrograde amnesia
Shows an autobiographical and semantic (factual) memory deficit; e.g. he knew he was a musician and conductor but couldn’t recall any concerts
Do procedural memories involve the hippocampus
No
What is the length of storage of the Episodic memory system (what is an example of it)
Minutes to years
-Remembering a short story, what you had for dinner last night, birthday
What type of awareness is Episodic memory
Explicit, declarative
Length of storage of Semantic memory system
What is it
Minutes to years
Knowing the PMs during WW2, colour of an elephant, how a fork differs from a comb
Length of storage of Procedural memory
What is it
Minutes to years
Driving a car with gears, learning sequence of numbers on a mobile without trying
Length of storage of memory of Working memory and what is it
seconds to minutes
Phonologic: keeping a phone number in your head.
Spatial: mentally following a route in your mind
What type of awareness is Semantic memory system
Explicit or implicit, declarative or non declarative
What type of awareness is working memory system
Explicit, declarative
Where is Semantic memory processed
Inferolateral temporal lobe
