Human failure detection and resource allocation in dynamic environments.

Three major areas of the research are summarized. 1) Processing resource allocation between task in dynamic environments. Results indicate that these abilities are distinctly limited. 2) Failure detection in dynamic systems. Human operators are found to be better at detecting failures when they are active participants in controlling those systems. 3) The attentional demands of failure detection. Task interference patterns between failure detection in the controlling versus the autopilot monitoring mode, and between two qualitatively loading tasks are shown to be consistent with a structure-specific resource view.
