This study investigates the neural and physiological mechanisms underlying External Referent Decision Awareness (ERDA) within organizational contexts, focusing on hierarchical roles (Head, Peer, Staff). Twenty-two professionals participated, and electroencephalographic (EEG frequency band: Delta, Theta, Alpha, Beta, Gamma) and autonomic indices (skin conductance and cardiovascular indices) were recorded, while personality traits and decision-making styles were assessed. Results revealed higher Delta and Theta activation in the left temporo-parietal junction (TPJ) during Peer-related decisions, reflecting increased social cognition and ambiguity regulation in those contexts. Gamma activity, associated with high-order cognitive processes, was prominent in the left frontal cortex across all roles, indicating complex decision evaluation. These findings underscore the complexity of low-frequency bands (Delta and Theta), involved in emotional regulation and social cognition, while high-frequency bands (Gamma) reflect cognitive integration and decision complexity. Furthermore, autonomic data showed higher Skin Conductance Levels (SCL) for Head decisions, suggesting greater emotional involvement.The findings revealed a significant negative correlation between avoidant decision-making styles and the neural and behavioral evaluations of leader decisions, suggesting reduced engagement of neurocognitive systems involved in reward processing and evaluative judgment in individuals with a tendency to avoid decision-making. Additionally, higher extraversion correlated with more favorable evaluations of decisions made by Staff, potentially indicating greater activation in neural circuits associated with social reward and group dynamics. In conclusion, these findings suggest that neural activity and personality traits interact to shape hierarchical decision-making awareness, highlighting the need for tailored leadership and decision-making strategies in organizations.
本研究调查了组织环境中外部参照决策意识（ERDA）背后的神经和生理机制，重点关注层级角色（领导、同事、员工）。22名专业人员参与了研究，记录了脑电图（EEG频段：δ波、θ波、α波、β波、γ波）和自主神经指标（皮肤电导率和心血管指标），同时评估了人格特质和决策风格。结果显示，在与同事相关的决策过程中，左颞顶联合区（TPJ）的δ波和θ波激活增强，反映出在这些情境中社会认知和模糊性调节的增加。与高阶认知过程相关的γ波活动在所有角色的左额叶皮层中都很突出，表明存在复杂的决策评估。这些发现强调了低频波段（δ波和θ波）在情绪调节和社会认知中的复杂性，而高频波段（γ波）反映了认知整合和决策复杂性。此外，自主神经数据显示，领导决策时的皮肤电导率水平（SCL）更高，表明情绪参与度更高。研究结果显示，回避型决策风格与对领导决策的神经和行为评估之间存在显著负相关，这表明在有回避决策倾向的个体中，参与奖励处理和评估判断的神经认知系统的参与度降低。此外，外向性越高，对员工决策的评价越积极，这可能表明与社会奖励和群体动态相关的神经回路激活程度更高。总之，这些发现表明神经活动和人格特质相互作用，塑造了层级决策意识，凸显了组织中需要量身定制的领导和决策策略。
