Abstract:

One of the most important findings on deception detection is that the accuracy rate is just slightly higher than the random level. Therefore, a number of researchers have paid attention to the impact of unconscious processing on deception detection. This article summarizes theories and empirical studies on unconscious deception detection. We presented three aspects of the empirical results: unconscious reception of information, unconscious thinking, and unconscious judgment. In view of the current findings, we proposed five approaches to studying unconscious processing in deception detection: proposing specific theories, exploring interactive deception situations, studying the cue-processing matching effect, examining effective physiological and brain activation indicators, and applying unconscious deception detection.

Key words: unconscious process, deception detection, dual process, unconscious thought theory, cue-processing matching effect
