WMM - Baddeley and Hitch

1. AO1

   • Central Executive
     • Attentional Processes
     • Monitors/Co-Ordinates with all other cognitive functions within WM
     • Directs Sensory Information to 'Slave Systems'
     • Limited Capacity
       • BxH states the info received her is either immediately allocated to slave system or lost
   • Phonological Loop
     • 2 Seconds
     • Acoustic Coding
     • Phonological Store
       • Processes Information Heard
     • Articulatory Process
       • Processes words heard or seen.
         • Maintainence rehearsal occurs, auditory information is looped around
   • VSS
     • Plan Spatial Tasks E.G. Moving around your environment, driving a car
     • Visual and Spatial information is stored
     • 3 or 4 Items of capacity
     • Visual Cache
       • Processes information about visual items
     • Inner Scribe
       • Processes Spatial relationship between item and other items within visual field
   • Episodic Buffer
     • Integrates Visual, Spaital and Verbal Information time sequencing them
       • Added to explain why some amnesiacs didn't fit in with the original model

2. AO3

   • Strengths
     • KF Again
     • Dual-Task Performance
       • Greater Difficulty completing 2 Tasks in same slave system than tasks with 2 different slave systems
         • Lacks ecological validity
   • Weaknesses
     • Eslinger and Damasio
       • EVR - Derebral brain tumours removed
         • EVR struggled to do problem solving using the CE
           • Could problem solve on paper but not in day-to-day decision making
             • Explanation of CE is not complex enough - EVR's impairments suggest a subdivision of CE
