ABSTRACT
One of the questions that arises in investigation of human multitasking is whether it is governed by general or task- specific executive processes (see, e.g., Kieras et al., 2000). On one hand, specialized training in specific sets of concurrent tasks clearly leads to improved performance, thus implying involvement of task-specific mechanisms. On the other hand, people are generally able to multitask relatively successfully when given new tasks or new task combinations. This ability to apply time-sharing skills to novel settings favors the idea of generic executive mechanisms involved in human multitasking.
