Primate foundation of cognitive development

人类和非人类灵长类动物之间的认知发展进行了比较。主要目标是与人类拥有最新共同祖先的黑猩猩。这项研究揭示了一个新的事实，即年轻的黑猩猩比成年人有更好的工作记忆。黑猩猩生活在此时此地的世界里。相比之下，人类经常在出生前思考过去，在死亡后思考未来。我们可以同情那些在偏远地区受苦受难的人们。总而言之，想象力是人类独有的。

Cognitive development was compared between humans and nonhuman primates. The main target was the chimpanzees that shared the latest common ancestor with humans. The study revealed the new fact that young chimpanzees have the better working memory than adult humans. Chimpanzees are living in the world of here and now. In contrast, humans often think about the past before the birth and the future after the death. We can be sympathetic to the people who are suffering in a remote place. In sum, the power of imagination is uniquely human.
