Q

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

A

Sensory store
Short term memory
Long term memory

2
Q

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

A

20 seconds

3
Q

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

A

7 +/- 2

4
Q

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

A

3 or 4 items

5
Q

What areas are involved in STM?

A
Parietal cortex
Prefrontal cortex 
Hippocampus 
Intraparietal sulcus
Inferior occipital areas
6
Q

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

A

Transient storage of visuospatial information

7
Q

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

A

Monitoring

8
Q

What two areas are involved in verbal STM?

A

BA 40 and BA 44 (Broca’s area)

9
Q

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

A

Rehersal

10
Q

What is the role of B40 in verbal STM?

A

Storage

11
Q

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

A

Prefrontal cortex

12
Q

What is Lashley’s principle?

A

There is no one specific area associated with LTM

13
Q

What is the evidence supporting Lashley’s principle?

A

In leison studies, the volume of tissue destroyed was directly linked to the level of memory, no matter the location of the leison

14
Q

What are the criticisms of Lashley’s principle?

A

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
Q

What part of the brain responds to familiar faces? LTM

A

Inferior temporal cortex

16
Q

How is the hippocampus involved in LTM?

A

Episodic memory

London taxi drivers have bigger hippocampi the longer they’ve been employed

17
Q

What is anterograde amnesia?

A

Can’t establish new memories

18
Q

What is reterograde amnesia?

A

Can’t remember what happened before the incident

19
Q

What is transient global amnesia?

A

Retro and anterograde amnesia together

Only lasts about a day and people make a complete recovery

20
Q

What is Korsakoff’s syndrome?

A

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

21
Q

Are memories stored in a single neuron or a network?

A

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
