task element

One might argue that if any complex human-machine task were broken down into sufficiently fine elements, each element would have to be assigned to either human or machine; but then how could one accommodate dynamic task allocation, in which sometimes a human does a task element manually and at other times assigns the element to automation (Moray et al., in press; Parasuraman et al., 1996)?

The DACUM process employs a group interactive activity to produce a sequenced chart of major duty categories and associated task elements of an occupation.

Wickens (1991) describes three cognitive processing issues: (1) multitasking can compete for the same levels of cognitive resources, leading to degradation in the primary task; (2) multitasking can lead to confusion when the task elements are similar; or (3) multitasking might not interfere with performance on different tasks when the elements are incompatible with each other.
