深思熟虑的目的是区分不同的选择，这样我们就可以选择一个，而放弃另一个。然而，自相矛盾的是，深思熟虑也可以在记忆中形成选择和未选择的选项之间的联系。在这里，我们考虑这种可能性，并研究其后果，即结果如何不仅影响我们选择的选项的价值，而且还通过关联影响我们没有选择的选项的价值。在五个实验中（共n = 612），包括一个预注册的实验（n = 235），我们发现，分配给未选择的选项的值是负相关的，他们选择的同行。此外，这种反向关系与参与者对他们选择的配对的记忆有关。我们的研究结果表明，在选项之间做出决定并不会结束它们之间的竞争。深思熟虑在记忆中将选择捆绑在一起，这样一个学习的价值可以影响另一个的推断价值。做出决定需要区分不同的选择，承诺一个，放弃另一个。在这里，作者表明，决策矛盾地将选项捆绑在一起，这样选择的结果最终会改变选择和未选择选项的价值，方向相反。
The goal of deliberation is to separate between options so that we can commit to one and leave the other behind. However, deliberation can, paradoxically, also form an association in memory between the chosen and unchosen options. Here, we consider this possibility and examine its consequences for how outcomes affect not only the value of the options we chose, but also, by association, the value of options we did not choose. In five experiments (total n = 612), including a preregistered experiment (n = 235), we found that the value assigned to unchosen options is inversely related to their chosen counterparts. Moreover, this inverse relationship was associated with participants’ memory of the pairs they chose between. Our findings suggest that deciding between options does not end the competition between them. Deliberation binds choice options together in memory such that the learned value of one can affect the inferred value of the other. Making a decision requires one to differentiate between choice options, committing to one and leaving the other behind. Here, the authors show that decision-making paradoxically binds options together, such that the outcome of the choice ends up changing the value of both the chosen and the unchosen options, in opposite directions.
