When someone lies, their body often betrays them through subtle changes in eye behavior. This is a result of the increased mental effort or cognitive load involved in lying.
EyeDetect employs a sophisticated optical scanner to detect these minute changes. It then uses advanced algorithms to calculate a credibility score. While a polygraph test measures emotional reactions to questions, EyeDetect focuses on the cognitive strain linked to dishonesty.
Why is lying more mentally taxing? Firstly, constructing a lie involves careful planning, comparing facts, and delivering intentionally false responses. This heightened alertness needed for deception leads to a greater cognitive burden. This strain manifests as more frequent errors in responses, longer times to answer questions, and increased periods spent reading and re-reading the material.
Secondly, lying demands cautiousness and strategic thinking. Indicators of this increased processing difficulty include prolonged response times, changes in pupil size, and the number of times the eyes fixate on text. There’s also a noticeable difference in how a person processes information when they first read it and upon re-reading.
Both EyeDetect and polygraph tests offer valuable, though partially distinct, insights into truth-telling. Used together, they can significantly enhance the accuracy of truth verification in various applications.
