Hoerl & McCormack suggest that saving tools does not require temporal reasoning. However, we identify a class of objects that are only possessed (i.e., saved) in anticipation of future needs. We propose that investigating these future-oriented objects may help identify temporal reasoning in populations where this ability is uncertain.

面向未来的对象

Hoerl & McCormack 建议保存工具不需要时间推理。然而，我们确定了一类仅在预期未来需要时才拥有（即保存）的对象。我们建议调查这些面向未来的对象可能有助于确定这种能力不确定的人群中的时间推理。
