I found this article by searching for the keyword "cognition of elephants". This article focuses on the difference between elephant cognition and other mammals. Experiments have shown that wild elephants divide humans into different categories, and classify them independently based on smell or skin color. In digital discrimination, elephants do not display the effect of absolute or relative size differences when making digital judgments. The experimental authors have concluded that any coincidence in cognitive skills between elephants and primates indicates a convergent evolution of specific abilities, so future research on elephant cognition provides a better understanding of choosing specific The potential of the evolutionary power of mental skills. This article is very important for me to study the cognition of elephants. I can investigate and research from different aspects such as smell and numbers.

This article mainly studies how elephants use tools. In the first part of the study, the author observed a juvenile elephant and 33 adult wild elephants observed in Nagarhole National Park in Karnataka, India. Eight of these elephants may be driven off by branches fly. In the second part of the study, which was also conducted in Nagarhole Park, the author showed 13 captive elephants in captivity under natural systems, and in two trials on each elephant Long branches, and gave them 5 minutes to try to switch using long branches, or modify branches and use the changed branches to switch. Eight of these elephants modified the branch to a smaller branch in at least one experiment and switched using the changed branch. In the end, the authors concluded that the fact that the cerebral cortex of elephants can be used for cognitive processing exceeds that of any primate species seems to make this animal among the top apes in the cognitive abilities of tool use and tool manufacturing. This article is very helpful for me to study the intelligence level of elephants.

By reading these two articles, I learned a lot of research methods, such as the control variable method and the group experiment method. At the same time, I have a deeper understanding of elephant cognition, which is of great help for me to study the intelligence level of elephants.
