所有具有长期记忆能力的生物体都必然面向未来。我们认为，长期情景记忆最重要的适应功能之一是存储有关过去的信息，为个人未来的规划服务。因为一个系统在从事一项最大限度地利用其进化机制的任务时应该具有特别有效的性能，我们预测，相对于其他记忆任务，面向未来的规划将导致特别好的记忆。我们测试了一个单词列表的回忆性能，使用不同时间视角的编码任务（例如，过去，未来，但类似的背景。与我们的假设一致，未来导向编码产生了上级回忆。我们讨论了这些发现的影响，他们的论文，记忆进化，使其拥有者能够预测和应对未来的突发事件，不能知道的确定性。
All organisms capable of long-term memory are necessarily oriented toward the future. We propose that one of the most important adaptive functions of long-term episodic memory is to store information about the past in the service of planning for the personal future. Because a system should have especially efficient performance when engaged in a task that makes maximal use of its evolved machinery, we predicted that future-oriented planning would result in especially good memory relative to other memory tasks. We tested recall performance of a word list, using encoding tasks with different temporal perspectives (e.g., past, future) but a similar context. Consistent with our hypothesis, future-oriented encoding produced superior recall. We discuss these findings in light of their implications for the thesis that memory evolved to enable its possessor to anticipate and respond to future contingencies that cannot be known with certainty.
