working model of memory

Question 1

who came up with the working model if memory

Answer 1

Baddeley and Hitch

Question 2

what are the four components to the wmom

Answer 2

central executive, phonological loop, episodic buffer, visuo-spatial sketchpad

Question 3

what is the purpose of the central executive

Answer 3

it is responsible for controlled processing e.g directing attention, maintaining task difficulty, and memory retrieval

Question 4

what is the purpose of the phonological loop

Answer 4

(the inner voice) temporarily holds verbal information

Question 5

what is the purpose of the visuospatial sketchpad

Answer 5

(inner eye) processes visual information and spatial information (visual cache and inner scribe)

Question 6

central executive

Answer 6

-attentional control system
-modality free
-limited capacity
-were decision making happens
-determines how resources are allocated

Question 7

what is the purpose of the episodic buffer

Answer 7

integrating information from several sources to create a unified memory

Question 8

phonological loop

Answer 8

-speech based storage system
-decay rate is two seconds
-articulatory system
-verbal rehearsal system
-limited capacity
-the inner voice
-form of maintenance rehearsal

Question 9

episodic buffer

Answer 9

-extra storage system
-limited capacity of 4 chunks
-integrates information from all other areas
-modality free
-links LTM to wider cognitive processes

Question 10

Answer 10

-temporary storage system
-visual (what things look like) and spatial (relationships between things)
-limited capacity
