WMM

• Who created the working memory model?

  Baddeley and Hitch
• the central executive: brings attention to the task, allocates resources to the task, and monitors performance.
• the episodic buffer: receives input from the STM and integrates the information to create a mental episode.
• phonological loop: holds information about words and their sounds, involved with maintenance rehearsal. it has a limited capacity.
• visuo-spatial sketchpad: a mental representation of the spatial relationships between objects and the locations of objects in the visual field.
• Strength of the WMM

  Evidence for the phonological loop through its explanation of the word length effect. Word length effect disappears if given an articulatory suppression task (‘repeating the, the, the) as rehearsal is stopped. the phonological loop explains articulatory process; key component of WMM.
• weakness of WMM

  Case studies from brain damaged patients is unreliable evidence. Brain damage can change behaviour or ability to make an individual perform worse on a task, mental issues affect attention span. lots of key research about the WMM comes from these case studies, and the results cannot be generalised.
