working memory

working memory

1. the memory system that includes two specialized short-term memories (auditory loop and visuospatial sketchpad) and a central executive that operates on information in the short-term memories to plan, reason, or solve a problem

2. has distinct components

   • articulatory loop
     • STM that holds verbally produced sounds
   • visuospatial sketchpad
     • STM that holds visual and spatial information
   • central executive
     • a set of processes that transforms and interprets information in the two STMs when you plan, reason, or solve a problem
       • example: when you are planning what to say on a first date

3. plays active role in cognition

   • "workbench" metaphor
     • “workbench” where information is temporarily stored and actively processed
       • Information that comes in through the senses must undergo active processing or it will be lost
