Eye Movements and Lie Detection
Accurate value-driven attention and lie detection are crucial for psychodiagnostics. Eye-tracking could be a way to improve the reliability and validity of psychological research. Benefits of eye-tracking are its non-invasive, speed recording, consciousness control proof. The first aim was to search for markers of attention to meaningful stimuli. Specifics markers and gaze patterns of value driven attention were found in contrast to the attention of neutral or composed-indented stimulus. The second aim was to find eye movements’ markers of deception. We found a stable complex of markers for reliably lie detection which is stimulus’ and deception’ type free. Also, specific markers allow differentiate any kinds of deception. Selected deception markers together with “value-driven” markers formed the basis of truth-or-lie detection technology for psychological testing. The special software has been developed what measure background of an individual response rate and allow to set flexible criteria for identifying false responses.
