Enhancing Cognitive Performance through Biocybernetic Feedback: An Individual Differences Approach.

摘要

For the present investigation, we systematically varied a workload task over a range of difficulties and sessions while eye movement elements and performance served as dependent variables. The objective was to determine whether task demands which are inherent in the stimulus (e.g., number of channels monitored; time on task) covaried with characteristics of the dependent variables. Although the approach was empirical, the elements selected for study followed from theory or findings reported previously in the scientific literature. The immediate goal of this work was to surface a series of objective indicators (both performance and bioelectric events) which vary systematically with workload (both operator dependent and operator independent). The intermediate goal is to develop a battery of measures and automated scoring algorithms to index the different forms of workload effects and operator state. The long-term goal of this work is the development of a bicybernetic device. Such a device would employ these suitable biomedical measures, analyze them in real time, and feed the information back to the machine (or operator) in order to modify systems performance.
