Executive Control of Cognitive Processes in Task Switching (via Joel on Software) -- "Task alternation yielded switching-time costs that increased with rule complexity but decreased with task cuing. These factor effects were additive, supporting a model of executive control that has goal-shifting and rule-activation stages for task switching. It appears that rule activation takes more time for switching from familiar to unfamiliar tasks than for switching in the opposite direction." (Comments: Long, boring academic article. However, as Joel points out, it provides some evidence that some people can't multitask.)
