  • Working Memory Model
    • COMPONENT OF WORKING MEMORY
      • Central executive
        • monitors and co-ordinates all other mental functions in working memory.
      • Phonological Loop
        • PHONOLOGICAL STORE: words that you hear
        • ARTICULATORY PROCESS : words that you hear or see
        • Encodes speech sounds in working memory, typically involving maintenance rehearsal.
      • Visuo-spatial skecthpad
        • Encodes visual information in terms of separate objects as well as the arrangement of these objects is in one visual field.
      • Episodic Buffer
        • Receives input from all components, temporarily stores the information and then integrates in order to create a mental episode of what is being experienced.
    • EVIDENCE SUPPORTING WORKING MODEL
      • Episodic Effect
        • BADDELEY found that when participants are shown words then asked to recall them immediately their performance is better which shows there is a immediate memory store for items that are neither visual or phonological
      • Phonological loop & articulatory process
        • BADDELEY   tested if the phonological loop explains how the word-length effect occurs. It was suggested holds the amount of information that you can say in 2 secs.
      • Visuo-spatial  skecthpad
        • BADDELEY demonstratedthe existence of the visuo-spatial skecthpad. Task 1 involved description and Task 2 was verbal. This is evidence for doing 2 tasks using same /different components.
  • Central executive
    • monitors and co-ordinates all other mental functions in working memory.
