Integrated Cognitive Computational and Biological Assessment of Workload in Decision Making

摘要

The project research is completed. Several manuscripts are still in the process of being prepared for publication. The project has developed paradigms to study high-level, high-demand cognitive tasks with fMRI. The project has discovered a surprising phenomenon regarding a mutual constraint on the total amount of cortical activation possible in a dual task situation. The project has determined the effects of input modality in dual tasking. The project has developed an experimental control system (CogLab NT) that will enable future fMRI investigation of the performance of dynamic tasks with some of the critical properties of high-information-load STE's. The project has developed paradigms to study high-level, high-demand dynamic cognitive tasks behaviorally. The project has developed brain-based measures of cognitive workload. The project has developed a theory of learning in dynamic decision environments, called Instance-Based Learning Theory (IBLT).
