Dispositional envy is distinguished by definition and neurally from episodic envy. While the neural correlates of episodic envy have been evaluated by specific tasks in previous studies, little is known about the structural neural basis of dispositional envy. In this study, we investigated the structural neural basis of dispositional envy underlying individual differences across two independent samples comprising a total of 100 young healthy adults. Firstly, 73 subjects' data (sample 1) was analyzed, and we assessed the association between regional gray matter volume (rGMV) and dispositional envy using voxel-based morphometry (VBM). Furthermore, we explored the role of emotional intelligence in the association between GMV and dispositional envy. VBM indicated that dispositional envy was positively correlated with GMV in the left dorsolateral prefrontal cortex (DLPFC) and superior temporal gyrus (STG). We also found that emotional intelligence partially mediated the association between DLPFC volume and dispositional envy. These results were replicated in another independent sample (Sample 2, n = 27). These results provide the first evidence that dispositional envy exhibits a structural neural correlation with the DLPFC and STG, and give a neutral explanation for why individuals with high emotional intelligence exhibit less envy.
特质嫉妒与情景嫉妒在定义和神经层面上是有区别的。虽然之前的研究已经通过特定任务评估了情景嫉妒的神经相关性，但对于特质嫉妒的结构神经基础知之甚少。在这项研究中，我们通过两个独立的样本（共包含 100 名年轻健康的成年人）调查了个体差异背后的特质嫉妒的结构神经基础。首先，我们分析了 73 名受试者的数据（样本 1），并使用基于体素的形态学（VBM）评估了区域灰质体积（rGMV）与特质嫉妒之间的相关性。此外，我们还探讨了情绪智力在 GMV 与特质嫉妒之间的关联中的作用。VBM 表明，特质嫉妒与左背外侧前额叶皮层（DLPFC）和颞上回（STG）的 GMV 呈正相关。我们还发现，情绪智力部分介导了 DLPFC 体积与特质嫉妒之间的关联。这些结果在另一个独立的样本（样本 2，n=27）中得到了复制。这些结果首次提供了证据，表明特质嫉妒与 DLPFC 和 STG 具有结构神经相关性，并为为什么情绪智力高的个体表现出较少的嫉妒提供了一个中立的解释。
