Studying Interpreters' Stress in Crisis Communication Evidence from Multimodal Technology of Eye-tracking, Heart Rate and Galvanic Skin Response

Abstract

This article references risk communication theory and cognitive load theory to analyse the stress experienced by interpreters involved in crisis communication within Covid-19 medical scenarios. It considers the nature of stress both from psychological (mental) and physiological perspectives, exploring the relationship between the level of cognitive load, physiological stress, and the quality of interpreting in crisis communication. This research identifies the strategies used by interpreters when operating in pandemic working environments and compares their cognitive load and physiological stress changes within and outside contexts of crisis communication. We hypothesize that interpreters experience greater psychological stress and an increased cognitive load which adversely affect their interpreting in crises compared to normal situations. To test this hypothesis, an experiment combined eye-tracking technology with Heart Rate and Galvanic Skin Response technology. 25 novice interpreters interpreted simulated medical scenarios for a Covid-19 patient and a diabetes patient respectively. This is one of the first studies to apply the multimodal approach of eye-tracking, HR, and GSR technology to record the physiological stress and mental status of interpreters. We advocate more systematic interdisciplinary research concerning interpreters' stress in crisis communication, and outline recommendations for future crisis interpreting training and for individual professionals involved in crisis management.
