  • 19. Short Term Memory Duration • 20 to 30 seconds • Depends… –Whether information is rehearsed – Whether there is interference
  • 20. Working Memory • System involved in holding information in mind needed to complete complex tasks in the face of interfering processes and distractions • Composed of three components – Central executive – Visuo-Spatial Sketchpad – Phonological loop
  • 21. Working Memory Characteristics • Domain specificity – Separable forms of processing – Domain specific disruption
  • 22. Working Memory Resource Limited (source of individual differences) • State differences – Situational demands can reduce amount of WM resources available • Trait differences – Some individuals generally have more WM resources to work with • Emphasis is on limits in attention not # items stored
