Regret is a common emotion that has important links with decision-making in adults. Recent research suggests that the ability to experience regret emerges relatively late in development. By around 6 years, most children will experience regret, but the likelihood of experiencing this emotion increases across childhood and into adolescence. The developmental emergence of regret seems to affect children’s decision-making: Children who experience regret about a choice are more likely to make a better choice next time, and regret also seems to help children learn to delay gratification and behave more prosocially.

后悔与决策：发展视角

遗憾是一种常见的情感，与成年人的决策有着重要的联系。最近的研究表明，体验后悔的能力在发展中相对较晚。到大约6岁时，大多数孩子都会感到遗憾，但是在整个童年和青春期经历这种情绪的可能性都会增加。后悔的发展出现似乎影响了孩子的决策：对选择感到后悔的孩子下次更有可能做出更好的选择，而后悔似乎也可以帮助孩子学会延迟满足和行为方式。
