Working memory model

Question 1

Phonological loop

Answer 1

• primary acoustic store (holds auditory memory traces, very limited a auditory information decays very rapidly)
• articulatory loop revives memory traces by rehearsing them, rehearsed by talking without vocalising
• phonological similarity effect- more difficult to remember similar sounding words

Question 2

Visuospatial scratchpad

Answer 2

• holds information we see and manipulates spatial information
• anything that uses spatial awareness
• said to be divided into visual, spatial and kineasthetic
• limited in capacity as it holds approximately 3-4 objects

Question 3

The central executive

Answer 3

• control other components of the working memory
• supervisory system that controls all cognitive processes
• limited capacity ability to deal with different types of sensory information

Question 4

Evalution

Answer 4

supporting evidence - Corsi block experiment more errors in tapping when number of boxes increases- visuospatial sketchpad has limited capacity
validity- model incomplete- episodic buffer added to model as a backup store
elements ignored - wmm only gives information as to what happens in the stm store proposed by atkinson and shriffin but does not offer an explanation to ltm - limited in how it can be used to explain aggression
