The halo effect of attractiveness influences not only physical appearance but also vocal characteristics, impacting people's lives and behaviors. Previous research has shown that voice may affect decision-making social interactions, its influence on cooperative behavior been thoroughly investigated. This study used neurophysiological methods, specifically EEG, to examine the impact in Stag Hunt Game. Participants played a two-person version game with virtual partner whose was either highly attractive or less attractive. EEG data recorded during game, focusing brain responses processing phase outcome feedback phase. results revealed "beauty premium" effect: participants were more likely cooperate when paired voice. Electrophysiological showed high-attractiveness voices elicited larger P2, P3, LPC amplitudes smaller theta oscillations During phase, both gain resulted FRN P300 amplitudes. In contrast, under conditions, loss triggered oscillations. These findings suggest significantly contexts. neural indicate can modulate early sensory (P2, LPC) evaluation (FRN, P300, theta). highlights role shaping provides new insights into mechanisms underlying decisions.
