Cognitive workload across subjective and electrodermal measures in relation to previous-night sleep

Introduction

Cognitive workload is commonly assessed using both subjective and physiological indicators, although these measures may reflect different aspects of task-related strain. Sleep duration may further modify perceived task demand without producing proportional changes in physiological activation. This study examined the association between perceived cognitive workload and electrodermal task reactivity, and explored whether previous-night short sleep was associated with higher subjective workload without increased electrodermal activation.
