1. STM is not just passive retention - working component made up of several systems; they are independent and 2 can work alongside without any interference to performance

2. Phonological loop:

   • Temporary store of speech info, phonological store = inner ear - temporary store, 2s, speech based, articulatory loop = inner voice - active rehearsal, linked to speech, PL purpose is LAD and holding onto info
   • Phonological similarity effect= errors more likely if sound similar, e.g. B and G, or words in a list, more likely to misremember as reduces discriminability of items in the store
   • Word length effect = span for short words is greater than long, words take less time to subvocalise and keeps refreshing memory trace, longer = memory trace fade
   • Unattended speech effect = performance impaired if other verbal info needs to be ignored, even: nonsense syllables, diff languages or music - have to filter to distinguish
   • Articulatory supression =preventing rehearsal by articulation e.g. repeating a word -> if visual = cannot us PL store, so no word length effect, if verbal = direct acess to store, still WLE but worse performance

3. VSSP:

   • Limited capacity system for spatial, visual and kinesthetic info, visual vache = shape/colour (what), inner scribe = spatial/movement (where), constructs and manipulates mental images
   • Mental scanning = manipulation of info, learn map and mentally scan from location

4. Central executive:

   • Limited capacity attentional system, no real storage, directs attention and switches between strategies, PFC involved
   • Dysexecutive syndrome = disruption of CE, frontal lobe damage, issues with: perseverance - cannot disrupt ongoing schema, utilization behaviour - auto responding to cues in environment, fail to focus and catatonia - remain motionless for hours

5. Episodic buffer:

   • Integrates info into single complex structure, can hold 4 pieces of different modal info, binds info about an object interacting with perception and LTM
