The Working Memory Model

    Cards (14)

    • what is the working memory model?
      Baddeley and Hitch said that the STM is not a unitary store, that it is made up of the central executive and the three slave stores: the phonological loop, the episodic buffer, and the visuospatial sketch pad.
    • the central executive
      • very limited capacity
      • allocates tasks to the three slave stores
    • the phonological loop
      • processes auditory information
      • allows for maintenance rehearsal by being made up of the articulatory process
    • the visuospatial sketch pad
      • combines visual and spatial awareness information to give us a 'complete picture'
      • it is divided into the inner scribe and visual cache.
      • capacity of the vss is 4-5 chunks according to Baddeley.
    • the episodic buffer
      • integrates all type of information from other stores. including auditory, visual and spatial
      • crucial for linking stm to ltm.
    • What was the main focus of Baddeley and Hitch's research study?
      Working memory model (WMM)
    • What were the two tasks participants performed in the study?
      Digit span task and verbal reasoning task
    • How did the number of digits affect participants' response times in the reasoning task?
      Response times increased slightly, by fractions of a second
    • Did participants make more errors in the verbal reasoning task as the number of digits increased?
      No, they did not make more errors
    • What does the study suggest about the use of the central executive and phonological loop?
      • Verbal reasoning task used the central executive
      • Digit span task used the phonological loop
    • What type of task was the digit span task?
      It required repeating a list of numbers
    • What type of questions were asked in the verbal reasoning task?
      True or false questions
    • What conclusion can be drawn about the relationship between the digit span task and the verbal reasoning task?
      The tasks utilize different components of working memory
    • KF case study
      • provides support for the wmm
      • suffered brain damage from a motorbike accident that damaged his stm
      • the impairment was mainly for verbal information, his memory for visual information was largely unaffected
      • shows the stm has separate components for different info
