Working memory model

• Working Memory Model

  Developed by Baddeley and Hitch (1974) as an expansion of STM from the MSM
• Components of the Working Memory Model

  • Central Executive
  • Phonological Loop
  • Visuo-Spatial Sketchpad
  • Episodic Buffer
• Central Executive

  • Attention, decision-making and controls the slave subsystems
• Phonological Loop

  • Handles spoken and written material, split into the inner ear and the inner voice
  • Inner ear holds speech-based information for 1-2 seconds
  • Inner voice rehearses auditory information
• Visuo-Spatial Sketchpad

  • Handles visual and spatial information, split into the inner eye and the inner scribe
  • Inner eye stores information about form and colour
  • Inner scribe arranges objects in our visual field
• Episodic Buffer

  • Temporary store that binds information from other components and maintains a sense of time
• Information in Working Memory

  • Stored for up to 30 seconds
  • Each store handles different sensory inputs
• The working memory model

  
• evaluations of the WMM as an explanation of memory

  🙂 evidence to support - Baddeley’s dual-task studies

  🙂 evidence to support - K.F. case study

  ☹️ criticism of the central executive
