working memory.

• who and when was the model made?

  by baddeley and hitch - 1974.
• what does the model suggest?

  the model explains how the stm actually functions and processes mental functions like learning a language.
• what are the 4 parts to the model?

  central executive, phonological loop, visual spatial sketchpad and episodic buffer.
• what is the central executive?

  plays a key role in attention but mainly oversees the other slave subsystems. it does not store anything.
• what is the phonological loop?

  involved with dealing with auditory information. split into articulatory loop (inner voice) and primary acoustic store (sound). only has duration of 2 seconds.
• what is the visual spatial sketchpad?

  deals with visual information. said to have a inner scribe and visual cache. has 3-4 chunks.
• what is the episodic buffer?

  integrates information from phonological loop and vss. can store four chunks.
• evaluate using S?


  Trojani + Grossi - they did a case study on SC who was brain damaged, found the damage had impacted PL but not VSS : shows they are separate.
• evaluate using C?


  msm. episodic buffer added by baddeley in 2000 suggesting it was inaccurate to begin with. purpose of central executive?
• evaluate using U?


  shallice and warrington - found with Kf who had amnesia post brain damage that he had a poor stm and recalled auditory information poorly but could recall well visually - proven in his recall better when he read words than when he heard them.
• evaluate using T?


  case studies and experiments.
