- Working Memory Model (STM)
- Baddeley & Hitch: involves active processing and STM storage
- central executive
- acts as a filter, determining which info attended to; processes in all sensory forms, directs info to other slave systems & collects responses; limited capacity
- visuo-spatial sketchpad (slave system)
- temporary memory holding visual & spatial info; limited capacity
- visual cache (visual data of form & colour stored)
- inner scribe (arrangement of objects is visual field; rehearses/ transfers info in visual cache to CE)
- phonological loop (slave system)
- temporary storage; holds auditory/ verbal info; limited capacity
- phonological store = inner ear (stores words heard)
- articulatory process = inner voice (allows maintenance rehearsal)
- episodic buffer (slave system) added by Baddeley in 2000
- acts as back up, temporary store for visual & acoustic info; communicates between LTM & slave systems
- supported by dual task studies (easier to do 2 tasks at same time if using diff processing systems)
- KF motorbike accident brain damage (forgetting of auditory info > visual info) suggests not just 1 STM store
- Baddeley et al: tracking task w/ imagery task (both involve VSS so difficulty) but w/ tracking task & verbal task = success
- articulatory suppression = can't verbally rehearse info whilst speaking out loud so rehearsal is prevented
- little is known about the CE (important part but unclear role), brain studies suggest CE isn't unitary; model doesn't fully explain link between WM and LTM
