Researchers reveal a dynamic attraction that primates share with humans. That is the ability to hear in conversations with other monkeys.
Previous experiments have shown that monkeys can form social connections to understand video games how humans behave. But this new research suggests that humans and primates may be more likely than previously thought.
The study, published in the journal Advances in science, shows that marmosets can hear and evaluate monkey conversations and shows a relationship with cooperative monkeys over the non – cooperative ones.
Lead author and researcher of Anthropology from the University of Zurich, Rahel Brügger explains that the study adds to the direct evidence that humans also pay attention to the actions of others, Inverse recitation.
“The study adds to the growing evidence that marmosets are not common and many animals are only passive observers of third-party interactions; they are capable of the interactions to understand and evaluate that, “she said.

Testing process
Brügger and her team used a combination of thermography and behavioral reports to understand how primates interpreted the monkey conversations. Thermography, also known as heat mapping, can help researchers understand the emotions of animal subjects that are invisible in behavioral reports.
according to Inverse, the researchers played audio recordings of six different monkey conversations both cooperatively and non-cooperatively that stimulated an emotional response from the monkeys at stage A of their experiment. The hearing is done by monkeys unrelated to the study, including babies crying for adult food chatting.
The researchers monitored the monkeys under an infrared heat camera as long as they did not stop the socialization between the monkeys to reduce their potential for prejudice or deterrence from human third parties.
At the same time, in step B, they opened the doors to a test area where they were broadcasting the audio recordings to the monkeys. They created | a Hollywood-like set where a mirror and set design make it appear like other marmoset monkeys in the test arena.
They saw how the monkeys got together and let them enter the area and saw if they would go back to their house or not.

How did the monkeys respond?
According to the researchers, they found interesting insights into how the monkeys handled the audio calls. CNN reported some minor gender differences between them as, female helper monkeys had the strongest temperature levels in response to the audible calls that are indicative of their desire to breed.
Male helper monkeys, on the other hand, showed a strong rise in nasal temperature which resulted in a decrease in arousal, thus showing relaxation.
In addition, the researchers also noted that the breeding monkeys did not on average show signs of temperature drop but also saw some differences. For example, female breeding monkeys are highly food-stimulated while the males show more controversy when they hear negative interactions between young and adult monkeys.
That means male breeding monkeys serve as caring members of their family. When they hear the negative audible calls, it provoked the more defensive and fatherly “fight or flight” response.
Psychology Today said that primates engage in social decoration to maintain and strengthen relationships between them. Overall, the study found that marmosets have committed skills in social thinking as humans. They use these skills to identify positive features about their future companion and in social co-operation, which are essential for their survival.
