The Ultimatum Game is an effective tool for understanding how social decision-making is influenced by emotions in both research and clinical settings. Previous findings have shown that the Ultimatum Game can evoke negative emotions, especially anger and aggression. In a sample of non-clinical adults (N = 143) we evaluated the sensitivity of an anger-infused version of the Ultimatum Game to individual differences in anger and irritability. Findings showed significant relationships between anger and aggressive behaviors in the Ultimatum game, but no association between irritability and aggressive behavior were observed. This indicates that the anger-infused Ultimatum Game is a promising method for studying individual differences in trait anger and anger expression. However, the relationship between decision-making in the anger-infused Ultimatum Game and irritability is less straight forward and needs further investigation. Therefore, when studying the behavioral responses of irritability, it would be beneficial to capture other behaviors beyond aggressive responses.
最后通牒博弈是一种有效的工具，可用于了解情绪如何在研究和临床环境中影响社会决策。先前的研究结果表明，最后通牒博弈会引发负面情绪，尤其是愤怒和攻击性。在一项非临床成年人样本（N=143）中，我们评估了愤怒注入版最后通牒博弈对愤怒和易怒个体差异的敏感性。研究结果表明，最后通牒博弈中的愤怒与攻击性行为之间存在显著关系，但易怒与攻击性行为之间没有关联。这表明愤怒注入版最后通牒博弈是研究特质愤怒和愤怒表达个体差异的有前途的方法。然而，愤怒注入版最后通牒博弈中的决策与易怒之间的关系并不简单，需要进一步研究。因此，在研究易怒的行为反应时，除了攻击性反应之外，捕捉其他行为将是有益的。
