An Investigation of the Use of Steady-State Evoked Potentials for Human Performance and Workload Assessment and Control.

Abstract

This program of research investigated Steady-State Evoked Potential (SSEP) measures to determine their utility for evaluating sensory inputs, workload, and performance variables in human operators. A primary purpose was to find techniques and measures that could be generalized to groups of subjects in operational environments. SSEP measures included power (amplitude), coherence, phase lag, and Relative Transmission Time (RTT). Included in this effort were studies of: 1. Frequency 'masking', where multiple frequencies were presented simultaneously. 2. Sensory inputs which may manipulate SSEP (e.g. color, intensity, cross-modality stimulation). 3. Correlation of SSEP measures with fatigue and task difficulty. 4. The relationship between performance in a tracking task and SSEP measures.
