1

What are the 3 main parts of the Atkinson-Shriffin model?

Sensory store
Short term memory
Long term memory

2

According to Atkinson and Shriffin, how long is our STM?

20 seconds

3

According to Baddeley, what is the capacity of the phonological short term memory?

7 +/- 2

4

According to Baddeley, what is the capacity of the visual STM?

3 or 4 items

5

What areas are involved in STM?

Parietal cortex
Prefrontal cortex
Hippocampus
Intraparietal sulcus
Inferior occipital areas

6

What is the role of the intraparietal sulcus in spatial STM?

Transient storage of visuospatial information

7

What are the role of medial frontal brain areas in STM tasks?

Monitoring

8

What two areas are involved in verbal STM?

BA 40 and BA 44 (Broca's area)

9

What is the role of Broca's area (BA44) in verbal STM?

Rehersal

10

What is the role of B40 in verbal STM?

Storage

11

What area of the brain is linked to the central executive?

Prefrontal cortex

12

What is Lashley's principle?

There is no one specific area associated with LTM

13

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

14

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

15

What part of the brain responds to familiar faces? LTM

Inferior temporal cortex

16

How is the hippocampus involved in LTM?

Episodic memory
London taxi drivers have bigger hippocampi the longer they've been employed

17

What is anterograde amnesia?

Can't establish new memories

18

What is reterograde amnesia?

Can't remember what happened before the incident

19

What is transient global amnesia?

Retro and anterograde amnesia together
Only lasts about a day and people make a complete recovery

20

What is Korsakoff's syndrome?

Severe anterograde and retrograde amnesia as well as leisons on the thalamus caused by alchohol

21

Are memories stored in a single neuron or a network?

Hebb argued that memories are distributed in a network where if one neuron is activated, the rest then follow which leads to the recall of a memory
