Working memory model

• Describe the phonological loop component

  one of the slave systems controlled by the central executive

  deals with auditory information

  can be subdivided into the phonological store (inner ear) and the articulatory process (inner voice)

  the phonological store stores the words you hear (in speech form)

  the articulatory process allows for maintenance rehearsal

  capacity is 1-2 seconds

  coding is acoustic
• Suggest one way in which the working memory model might be a better explanation of short-term memory than the multi-store model.

  it is not a unitary store

  range of research support, eg dual task studies, brain scanning studies the WMM explains STM as a more active process than the MSM.
• Describe working memory model

  a model of STM which sees this store as non-unitary and an active processor

  consists of central executive which is supported by several slave systems such as phonological loop, visuo-spatial sketchpad and episodic buffer
• Describe the visuo-spatial sketchpad

  capacity: 3-4 items

  coding: visual + spatial information

  can be divided into passive visual store called visual cache which is linked to an active store called the inner scribe

  visual cache specialises in visual information including form, colour

  inner scribe specialises in infromation about spatial location, movement and planning
• Describe episodic buffer

  capacity : 4 chunks

  coding : visual, spatial, auditory
