Multitasking - Review

  • Context Switching
  • Broadman’s Area 10
  • Cognitive Load : the use of 7-digit phone
  • numbers. Ex:2341957

The Problem State

  • Blood oxygen level dependent activity in the

posterior parietal cortex that correlates with transformation on mental representations.

Threaded Cognition & ACT-R

  • Threaded cognition is an integrated theory of

concurrent multitasking - that is, doing two or more things at once.

  • ACT-R is a cognitive architecture in which a

human task can be modeled by breaking into discrete operations.
