Monkeys shared geometric representations with humans

Scientists from the USA conducted an experiment in which rhesus macaques and baboons exhibited a perception of geometric shapes similar to that of humans.

The experiment involved preschoolers, monkeys, and adult humans from the Himba and Tsimane tribes. Participants had to choose the geometric shape that resembled the sample the most.

To process the results, the scientists used the CORnet neural network, which models how the brains of primates process visual information.

The results showed that monkeys, like humans, relied on high-level representations and symbolic features, especially when the shapes were rotated relative to the sample.

The work of the scientists was published in the Proceedings of the National Academy of Sciences.
