working memory model

Question 1

central executive

Answer 1

• monitors incoming data
• focuses/divides ‘slave systems’
• limited processing capacity
• doesn’t store info

Question 2

phonological loop

Answer 2

• auditory info
• preserves order info arrives
• PHONOLOGICAL STORE: stores words we hear
• ARTICULATORY PROCESS: performs maintenance rehearsal, capacity of 2 secs

Question 3

visuospatial sketchpad

Answer 3

• stores + processes info in a visual or spatial form
• used for navigation
• capacity of 3-4 objects
• INNER SCRIBE: spatial + movement info, rehearses info to be sent to central executive
• VISUAL CACHE: stores info on form + colour

Question 4

episodic buffer

Answer 4

• temporary store
• combines visual, spatial, verbal info through time sequencing
• combines what you hear + see into one memory

Question 5

AO3 strength (performance)

Answer 5

• duel task performance supports separate visuospatial sketchpad
• Baddeley 1975: performance declines when multiple stimuli for same sense
• senses work separately and have limited capacity

Question 6

AO3 strength (study)

Answer 6

• clinical evidence to support, case study
• KF suffered brain injury in accident, after he could remember visual stimuli better than auditory letters + digits
• adds external validity to theory
