WMM

• the working memory model is an explanation of how one aspect of short term memory is organised and how it functions
• WMM refers to the part of the mind active when it is temporarily storing and manipulating information.
• central executive is an attentional process that monitors incoming data, makes decision and allocates slave systems to tasks.

  Has a very limited processing capacity.
• Phonological loop is a slave system that is responsible for auditory information and preserves the order in which the info arrives.
• phonological store stores the words heard
• articulatory process allows maintenance rehearsal

  (capacity of this loop is believed to be two seconds)
• Visuo-spatial sketchpad is a slave system which stores visual and/or spatial information when required.

  Has a limited capacity of three to four objects (Baddeley, 2003)
• visual cache stores visual data
• inner scribe records the arrangement of objects in the visual field
• Episodic buffer is a slave system that holds information temporarily from the other systems and processes it into a single unit. Also, maintains a sense of time-sequencing.

  Has a limited capacity of about four chunks (Baddeley, 2012)

  Links WMM memory to LTM and wider cognitive processes such as perception.
