Lie Detection Technique
Journal Title: International Scientific Research Organization Journal - Year 2015, Vol 1, Issue 1
Abstract
This work tested the hypothesis that there are physiological differences that manifest when a person tells a lie compared to when they tell the truth. It was predicted that when a person lies, their sweat production would increase, while their respiratory rate and heart rate would decrease. Thirty subjects were asked to tell four truths and one lie by answering questions about what they chose. The subjects were tested for respiratory rate and heart rate and those values were compared to baseline. It was found that there was a significant increase in respiratory rate and heart beat when they lied compared to when the subjects told the truth. The conclusions drawn from this study might help us develop instruments which are more sensitive and reliable at detecting falsehoods in comparison to the polygraph test.
