Diagnosticity of Cardiac Modes of Autonomic Control Elicited by Simulated Driving and Verbal Working Memory Dual-Tasks

摘要

The present study investigated the diagnosticity of autonomic space for heart rate by elucidating psychological-physiological mappings in a dual-task driving simulation. Based on the results of previous studies, we predicted patterns of cardiac autonomic activity that would be elicited by dual-task driving with a verbal working memory side-task. The results generally supported the predictions made, and indicate that cardiac autonomic modes of control can be diagnostic with regard to the attentional processing resources used during task performance in the driving domain.
