Flashcards in 5: Memory Deck (21)
What are the 3 main parts of the Atkinson-Shriffin model?
Short term memory
Long term memory
According to Atkinson and Shriffin, how long is our STM?
According to Baddeley, what is the capacity of the phonological short term memory?
7 +/- 2
According to Baddeley, what is the capacity of the visual STM?
3 or 4 items
What areas are involved in STM?
Inferior occipital areas
What is the role of the intraparietal sulcus in spatial STM?
Transient storage of visuospatial information
What are the role of medial frontal brain areas in STM tasks?
What two areas are involved in verbal STM?
BA 40 and BA 44 (Broca's area)
What is the role of Broca's area (BA44) in verbal STM?
What is the role of B40 in verbal STM?
What area of the brain is linked to the central executive?
What is Lashley's principle?
There is no one specific area associated with LTM
What is the evidence supporting Lashley's principle?
In leison studies, the volume of tissue destroyed was directly linked to the level of memory, no matter the location of the leison
What are the criticisms of Lashley's principle?
The study used rats in a maze which uses multiple forms of sensory memory. Hinderence to just 1 type of memory would make it difficult to complete the task
What part of the brain responds to familiar faces? LTM
Inferior temporal cortex
How is the hippocampus involved in LTM?
London taxi drivers have bigger hippocampi the longer they've been employed
What is anterograde amnesia?
Can't establish new memories
What is reterograde amnesia?
Can't remember what happened before the incident
What is transient global amnesia?
Retro and anterograde amnesia together
Only lasts about a day and people make a complete recovery
What is Korsakoff's syndrome?
Severe anterograde and retrograde amnesia as well as leisons on the thalamus caused by alchohol
