NEURAL DYNAMICS OF CONCEALMENT: EEG-BASED INSIGHTS FOR EDUCATIONAL AND BEHAVIORAL SCIENCES
Abstract
Concealment behavior involves complex cognitive and emotional processes that can be quantified using electroencephalography (EEG). This study investigates neural differences between states of sincerity and lying in 39 participants, using the Unicorn Hybrid Black system (8 sensors). EEG data were filtered, normalized and statistically analyzed in SPSS. Paired t-tests revealed significant increases in beta and gamma power in frontal (Fz), central (Cz, C4) and parietal (Pz) regions during lying. These patterns suggest heightened cognitive load, conflict monitoring and emotional inhibition. Cortical asymmetry and intercortical coherence indicate activation of executive networks responsible for behavioral regulation. Findings support theoretical models emphasizing the role of frontal neurocognitive systems in covert behavior and confirm EEG as a viable method for estimating dissimulation. Additionally, the present results contribute to the ongoing refinement of electrophysiological approaches used in the assessment of internal cognitive states under socially constrained conditions.
