Abstract

The purpose of this project is to provide a technical overview of heart rate variability (HRV) as an objective psychophysiological measure of cognitive workload in the field of human factors psychology. HRV measures the variation in time between subsequent heartbeats, primarily focusing on R-spikes due to their high amplitude. Measured through electrocardiography (EKG or ECG), HRV uses the BIOPAC hardware and the AcqKnowledge software systems to collect, display, and analyze the data. There are two domains of HRV; one of which focuses on the variability in heart rates as a function of time and the other as a function of frequency. Objective physiological measures may be combined with subjective measures such as self-report assessments in order to more accurately assess cognitive workload in a given situation. Implications of HRV as an indicator of workload, examples of its use in the literature, and a future project proposal are also discussed.
