working memory

Question 1

What is the working memory?

Answer 1

System for temporary storage and manipulation of information

Question 2

What does the central executive do?

Answer 2

Directs attention towards one or another stimuli and decides what will be put into the working memory

Question 3

What does the phonological loop do?

Answer 3

To do with verbal information

Question 4

What does the visuo-spatial sketchpad do?

Answer 4

To do with visual information

Question 5

What does the episodic buffer do?

Answer 5

Temporary storage and manipulation of information from 3 other systems

Question 6

1. Phonological loop

Answer 6

Serial recall was worse with phonologically similar list. We use the phonological loop on STM tasks

Long words take longer to rehearse and also produce lower memory spans

Question 7

2. Visuo-spatial sketchpad

Answer 7

We have the spatial span of around 6 items

Question 8

3. Central executive

Answer 8

Attentional system, selecting and controlling information flow
Damage to the frontal lobes of the cortex can cause impairments to the central executive
Functions:
-switching of retrieval plans
-timesharing in dual-task studies
-selective attention to certain stimuli while ignoring others
-temporary activation of long-term memory

Located in the dorsolateral prefrontal cortex
