WMM

• WMM-

  • Baddeley and Hitch 1974
  • Central executive: the supervisor that monitors incoming data and divides the limited attention by allocating the information to subsystems, it doesn’t hold any data.
  • Phonological loop: auditory information while preserving the order. The phonological store stores the words we hear, while the articulatory process allows maintenance rehearsal with a capacity of 2 seconds worth of words.

  • Baddeley and Hitch 1974
  • Visuo-spatial sketch pad: stores visual and/or spatial information (visualising a question like how many windows you have), it’s a limited capacity of 3-4 items (Baddeley 2003). There is the visual cache which stores visual data and the inner scribe which records the arrangement of objects in the visual field (Logie 1995).
  • Episodic buffer: (Baddeley 2000) temporary store for the visual, spatial and verbal information while preserving its order like its storing ‘episodes’ of what’s happening, with capacity of 4 chunks (Baddeley 2012), links to LTM.

  CPS- Shallice and Warrington (1970) – KF’s brain injury had poor STM for auditory info but could process visual information normally, so the phonological loop was damaged but not the visuo spatial sketch pad.

  CPW- Unsure if KF had previous cognitive impairments that could have also affected his memory.
• WMM-

  S- Dual task performance (Baddeley 1975) – participants arrived out visual and verbal tasks at the same time, performance being similar when they were performed alone, but when there was the same type of task performance declined due to thee being no difference in the subsystems.

  W- Baddeley (2003) ‘the central executive is the most important but the least understood’.
