"Dual-Task Interference and Cognitive Architecture"
Presented on September 23, 2004
Location: The Crick Conference Room
Mandler Hall, room 3545
- Abstract:
- Most people claim to be able to perform "easy" cognitive tasks
simultaneously.
However, objective measurement often reveals interference when even
seemingly trivial tasks are paired, so long as distinct decisions or
planning of distinct responses is required. Experiments
manipulating the duration of different stages in dual-task experiments
indicate stubbornly serial processing in central stages, including but
not limited to response selection. This queuing limitation
can be dissociated from sensory or perceptual attention and does not seem
well characterized by concepts like "central executive", nor
does it seem to be a shareable resource. Recent controversy over
the role of strategies in producing central queuing will be discussed,
along with recent findings on dual memory retrievals and evidence
suggesting that anatomical overlap is not a necessary condition for
obligatory queuing.
