Children's time estimation literature lacks of studies comparing prospective and retrospective time estimates of long lasting ecological tasks, i.e. tasks reflecting children's daily activities. In the present study, children were asked to estimate prospectively or retrospectively how much time they played a video game or read a magazine. Regardless of the task, the results revealed that prospective time estimates were longer than the retrospective ones. Also, time estimates of the video game task were longer, less accurate and more variable than those of the reading task. The results are discussed in the light of the current literature about time estimation of long lasting ecological tasks.
儿童时间估计文献缺乏比较长期生态任务的前瞻性和回溯性时间估计的研究，即反映儿童日常活动的任务。在本研究中，要求儿童前瞻性或回溯性地估计他们玩电子游戏或阅读杂志的时间。无论任务如何，结果都表明前瞻性时间估计比回溯性时间估计长。此外，与阅读任务相比，电子游戏任务的时间估计更长、更不准确且更具变异性。这些结果是根据关于长期生态任务时间估计的当前文献进行讨论的。
