Electrodermal activity in polygraph testing

Abstract

Electrodermal Activity (EDA) is considered one of the most informative physiological responses to emotional stress, providing extensive data. This research is dedicated to investigating the measurement of EDA within the context of polygraph testing, utilizing the specialized LXSoftware. It includes a comprehensive analysis of EDA signal, with a particular emphasis on its correlation with various types of polygraph questions. Additionally, the study examines the characteristics of the EDA signal and factors that may potentially influence the measurements.
