Working memory model

Question 1

what is it

Answer 1

• theoretical framework of STM that includes several components
• Braddely and Hitch working memory model suggests that STM is not a single store but rather consists of a number if different stores

Question 2

the central executive

Answer 2

• an attention control system that monitors and coordinates the operations of the other subordinate components which are called slave systems
• it decides how and when the slave systems are used
• capacity to focus attention, to divide attention between two or more sources and to switch attention from one task to another
• limited capacity cannot attend to a lot of things
• modality free, process and sensory information whether it be auditory or visual

Question 3

the phonological look

Answer 3

-auditory component of STM and it is divided into two components
- the articulatory control system and phonological store

Question 4

the articulatory control system

Answer 4

-linked to speech production which can hold information in a verbal form
- when you try to rmbr a telephone number and repeat it to yourself
- hold words ready for cognitive tasks (as you prepare to speak)

Question 5

phonological store

Answer 5

• linked to speech perception
• holds auditory memoru
• memory trace can only last from 1.5 to 2 seconds if it is not rehearsed by the articulatory control system
• can receive information directly from sensory memory in the form of uditory material
• any activity that requires retention of a verbal sequence; counting objects would rely on the phonological loop

Question 6

the visuospatial sketchpad

Answer 6

• visual component of STM
• temporary store for visual and spatial information from either sensory memroy or LTM
• includes storage and manipulation of visual patterns and spatial movements
• helps us rmbr not only what visual information is important but also where it is

Question 7

the episodic buffer

Answer 7

-temporarily holds several sources of information actve at the same time
- auditory and visual information together as well as info from LTM
- act as temporary and passive display store
