Abstract

Prior research using psychometric measures has yielded mixed results regarding the relationship between neuroticism and ethical risk-taking. Considering the pivotal role of ethical risk perception in influencing both ethical risk-taking and broader organizational outcomes, it is essential to explore its connection with neuroticism and the neural mechanisms underlying this link. This study employed voxel-based morphometry analysis of structural MRI data to investigate the neural correlates of ethical risk perception, measured by gray matter volume (GMV), and its association with neuroticism in a sample of 214 healthy, full-time employees. Whole-brain regression analysis revealed a negative correlation between ethical risk perception and GMV in the left precuneus. Mediation analysis further identified GMV in the left precuneus as a mediator in the relationship between neuroticism and ethical risk perception, controlling for demographic factors, total GMV, and the other traits within the Big Five personality model. These findings offer valuable insights into the neurostructural underpinnings of ethical risk perception and highlight the critical role of GMV in the left precuneus in linking neuroticism with ethical risk perception, enhancing our understanding of the neural mechanisms driving risk decision-making in the ethical domain.

雇员的神经质和道德风险感知：左楔前叶神经结构的相关性

先前使用心理测量法的研究得出了关于神经质和道德冒险之间关系的复杂结果。考虑到伦理风险感知在影响伦理风险承担和更广泛的组织结果方面的关键作用，有必要探索其与神经质的联系以及这种联系背后的神经机制。本研究采用基于体素的形态学分析结构MRI数据，以灰质体积（GMV）测量道德风险感知的神经相关性，及其与神经质的关系，研究214名健康全职员工的样本。全脑回归分析显示左楔前叶伦理风险感知与GMV呈负相关。中介分析进一步发现，在人口统计学因素、总GMV和大五人格模型中的其他特征的控制下，左楔前叶GMV在神经质和伦理风险感知之间的关系中起中介作用。这些发现为伦理风险感知的神经结构基础提供了有价值的见解，并突出了左楔前叶GMV在连接神经质与伦理风险感知方面的关键作用，增强了我们对伦理领域驱动风险决策的神经机制的理解。

期刊介绍： Biological Psychology publishes original scientific papers on the biological aspects of psychological states and processes. Biological aspects include electrophysiology and biochemical assessments during psychological experiments as well as biologically induced changes in psychological function. Psychological investigations based on biological theories are also of interest. All aspects of psychological functioning, including psychopathology, are germane. The Journal concentrates on work with human subjects, but may consider work with animal subjects if conceptually related to issues in human biological psychology.
