Memory

• What is the role of the Central Executive in the Working Memory Model?

  It decides what stimuli to process
• How does the Central Executive manage information in the Working Memory Model?

  It quickly passes info to a slave system
• What are the two parts of the Phonological Loop?

  Articulatory Control System and Phonological Store
• What is the function of the Articulatory Control System?

  It allows silent rehearsal of speech-based info
• What is the duration of the Phonological Store?

  2 seconds
• What does the Visuo-Spatial Sketchpad help us with?

  Processing visual or spatial stimuli
• What is the function of the Episodic Buffer?

  It links working memory to long-term memory
• What evidence supports the different parts of the Working Memory Model?

  Brain imaging studies show different brain areas active
• What does the case study by Farah (1988) suggest about the Visuo-Spatial Sketchpad?

  It may not be a single store
• What is a limitation of the Central Executive in the Working Memory Model?

  Its functions are vague and difficult to test
• What is the capacity of the Sensory Register?

  Huge capacity
• How long does information last in the Sensory Register?

  Less than a second
• What happens to unattended information in the Sensory Register?

  It is forgotten
• How can information be maintained in Short-term Memory (STM)?

  By using maintenance rehearsal
• What is the duration of Short-term Memory?

  30 seconds
• What is the purpose of elaborative rehearsal?

  To transfer information to long-term memory
• What evidence supports the existence of separate stores in the Multi-store Model of Memory?

  Brain imaging studies show different brain areas active
• What did the case study of KF (Shallice & Warrington, 1970) demonstrate?

  It supported the existence of STM and LTM
• What is a limitation of the Multi-store Model of Memory?

  It oversimplifies the types of long-term memory
