Lying Game Levitan et al, 2015

Hyperscanning Astolfi et al, 2011

Experimental Design Hyperscanning EEG during lying game Equipment: Simultaneous EEG system (Mesgarani) Soundproof booth and speech recording equipment (Hirschberg) Analyze neural oscillations in biologically relevant frequency bands Measure of cognitive load

Evaluating Results Analyze oscillatory power as measure of cognitive load Deceiver: deception vs truth-telling Detector: confidence Analyze synchrony between deceiver and detector Coherence, phase locking value, mutual information, circular correlation coefficient Compare deception and truth-telling, including across confidence levels
