Answer 4

The:
1. Phonological loop (PL) and the visuo-spatial sketchpad (VSS) deal with the processing and temporary storage of specific types of information
,but have limited capacity and
2. Central executive (CE) has no storage capacity and so cannot contain items relating to visual and acoustic properties

Question 5

Baddeley (2000) added a 3rd slave system, the episodic buffer, because the model needs a general store to operate properly.
The phonological loop (PL) and the visuo-spatial sketchpad (VSS) deal with the processing and temporary storage of specific types of information, but have limited capacity and the central executive (CE) has no storage capacity and so cannot contain items relating to visual and acoustic properties.
Therefore, the episodic buffer (EB) was introduced to explain how?

Answer 5

Therefore, the episodic buffer (EB) was introduced to explain how it is possible to temporarily store information combined together from the:

1. Central executive (CE)
2. Phonological loop (PL)
3. Visuo-spatial sketchpad (VSS)
4. LTM

Question 6

The episodic buffer (EB) maintains a sense of what?

Answer 6

The episodic buffer (EB) maintains a sense of time sequencing

Question 7

The episodic buffer (EB) maintains a sense of time sequencing, as it basically does what?

Answer 7

The episodic buffer (EB) maintains a sense of time sequencing, as it basically records events (episodes) that are happening

Question 8

The episodic buffer (EB) can be seen as the what of the central executive (CE)?

Answer 8

The episodic buffer (EB) can be seen as the storage component of the central executive (CE)

Question 9

The episodic buffer (EB) can be seen as the storage component of the central executive (CE) and has a what capacity of what according to who (what year)?

Answer 9

The episodic buffer (EB):

1. Can be seen as the storage component of the central executive (CE)
2. Has a limited capacity of about 4 chunks according to Baddeley (2012)

1. Verbal
2. Spatial
information

Question 13

Research:
Prabhakaran et al. (2000) used fMRI scans to find greater right-frontal brain activation for combined verbal and spatial information, but what for non-combined information?

Answer 14

Prabhakaran et al. (2000) used fMRI scans to find:
1. Greater right-frontal brain activation for combined verbal and spatial information
,but
2. Greater posterior activation for non-combined information
,providing biological evidence of an episodic buffer (EB)

Answer 15

Prabhakaran et al. (2000) used fMRI scans to find:
1. Greater right-frontal brain activation for combined verbal and spatial information
,but
2. Greater posterior activation for non-combined information
