Working memory model

• What is the working memory model proposed by Baddeley & Hitch in 1974?


  The working memory model consists of four components: central executive, phonological loop, visuospatial sketchpad, and episodic buffer.
• What is the role of the central executive in the working memory model?


  The central executive monitors incoming data and has very limited storage capacity.
• What is the capacity of the central executive in the working memory model?


  The capacity of the central executive is very limited.
• How does the phonological loop function in the working memory model?


  The phonological loop deals with auditory information and preserves the order of information.
• What is the capacity of the phonological loop?


  The capacity of the phonological loop is 2 seconds worth of information.
• What type of coding does the phonological loop use?


  The phonological loop uses acoustic coding.
• What is the function of the visuospatial sketchpad in the working memory model?


  The visuospatial sketchpad stores visual and/or spatial information when required.
• What is the capacity of the visuospatial sketchpad?


  The capacity of the visuospatial sketchpad is about 3 or 4 objects.
• What type of coding does the visuospatial sketchpad use?


  The visuospatial sketchpad uses visual coding.
• What is the role of the episodic buffer in the working memory model?


  The episodic buffer provides a temporary store for information received by the central executive and maintains a sense of time frequency.
• What is the capacity of the episodic buffer?


  The capacity of the episodic buffer is limited, about 4 chunks.
• What type of coding does the episodic buffer use?


  The episodic buffer uses modality-free coding.
• The central executive is responsible for controlling attention, planning, problem solving, and coordinating information from the phonological loop, visuospatial sketchpad, and episodic buffer.
• The phonological loop deals with auditory information and preserves the order in which information arrives.
• The visuospatial sketchpad is involved in the temporary storage and manipulation of visual and spatial information.
• Baddeley's working memory model suggests that there are three main components: the central executive, which controls attention; the phonological loop, which deals with sounds; and the visuo-spatial sketchpad, which handles visual and spatial information.
• The phonological loop is responsible for the temporary storage of auditory information.
