Lie to my face: An electromyography approach to the study of deceptive behavior.

ABSTRACT:

Background

Deception is present in all walks of life, from social interactions to matters of homeland security. Nevertheless, reliable indicators of deceptive behavior in real-life scenarios remain elusive.

Methods

By integrating electrophysiological and communicative approaches, we demonstrate a new and objective detection approach to identify participant-specific indicators of deceptive behavior in an interactive scenario of a two-person deception task. We recorded participants' facial muscle activity using novel dry screen-printed electrode arrays and applied machine-learning algorithms to identify lies based on brief facial responses.

Results

With an average accuracy of 73%, we identified two groups of participants: Those who revealed their lies by activating thei
