Working Memory Model

• Central executive (CE)-Controls working memory by monitoring incoming data, allocating limited attentional resources and subsystems to tasks.
• Phonological loop (PL)Subsystem processing auditory/verbal material. Subdivided into: phonological store and auditory process
• • Phonological store-Temporary storage of verbal material.
  • Articulatory process-Maintenance rehearsal of verbal material.
• Visuo-spatial sketchpad (VSS)Processes visual and spatial information by storing (visual cache) and manipulating it (inner scribe).
• Episodic buffer (EB)Integrates information processed in the other subsystems and links with LTM.
• One strength of WMM is there is evidenced for dual task performance. Baddeley's football/driving study in 1975 showed ppts couldn't drive and watch football, but could drive and listen to music as they use different features of WMM.
• one limitation of WMM is Baddeley said the central executive is the most important but least understood component.
• one strength is KF had poor memory for verbal but normal for visual- implies that his PL was impaired but his VSS was intact. However it is unsure if KF had other cognitive impairments as his accident was traumatic.
