人类在生态和人口方面取得的巨大成功在很大程度上归功于我们积累文化的能力，知识和技术随着时间的推移而积累，但使文化积累成为可能的社会和认知能力仍然不清楚。在一项序列问题解决的比较研究中，我们给卷尾猴、黑猩猩和儿童提供了一个实验性的拼图盒，可以分三个阶段解决，以获得越来越多的奖励。孩子们的成功，而不是黑猩猩或卷尾猴，在达到更高层次的解决方案是密切相关的一个包的社会认知过程，包括教学通过口头指令，模仿，亲社会性，这是观察到只有在儿童和与性能协变。
The remarkable ecological and demographic success of humanity is largely attributed to our capacity for cumulative culture, with knowledge and technology accumulating over time, yet the social and cognitive capabilities that have enabled cumulative culture remain unclear. In a comparative study of sequential problem solving, we provided groups of capuchin monkeys, chimpanzees, and children with an experimental puzzlebox that could be solved in three stages to retrieve rewards of increasing desirability. The success of the children, but not of the chimpanzees or capuchins, in reaching higher-level solutions was strongly associated with a package of sociocognitive processes—including teaching through verbal instruction, imitation, and prosociality—that were observed only in the children and covaried with performance.
