Stress variations and auditory omissions: a pilot study

Abstract

Neuroergonomics, e-conference, , 11-/09/2021 - 16/09/2021The use of auditory alerts is widespread in peripheral monitoring activities, where the attentional focus of the operator can be diverted from the monitored system toward a secondary task (Hermann et al., 2011). In such activities, an attentional cross-modal phenomenon can arise, leading to omit critical auditory alerts when the operator presents an over-engagement toward a visual task (Dehais et al., 2019). This pilot study had two objectives: - Explore the occurrence of ID (behaviorally defined as the occurence of omissions) during a secondary task imitating those which could take place in large-public contexts (e.g., autonomous driving), and its neurophysiological correlates. - Study the suitability of subtle biofeedback stress reduction and examine whether it affects the occurrence of ID (Béquet, Hidalgo-Muñoz & Jallais, 2020)
