Rhesus monkeys are pretty bad hombres, as you can tell from this picture, which of course, I've chosen for the purpose.
The rhesus would bite the finger, which hurts.
The rhesus monkeys would do that with the cloth mother.
And so with the rhesus monkeys and many different primates, they've identified about 15% to 20% are called uptight versus laid back.
And so with the rhesus monkeys and many different primates, they've identified about 15 to 20% are called uptight
of 40 or 50 rhesus monkeys who live in this natural 6-acre habitat that has vast amounts of land.
So in rhesus monkeys, people have been working on a chip that goes into the frontal cortex, the most executive part of your brain that controls attention and
So they take these rhesus monkeys.
They took these uptight babies in the rhesus macaque population in another enclosure where
They had this colony of rhesus monkeys.
The amazing thing was that the rhesus adopted it.
And one of the interesting things about infant rhesus macaques is that they have these two behavioral phenotypes.
So a stumptail would be sitting on a branch and a rhesus would come over and say, get off of my branch.
Studies done with vervet monkeys, with rhesus monkeys, and with chimps shows the same sex-specificity of toy preferences.
And monkeys are often used-- rhesus monkeys particularly-- in psychological research, because they display some characteristics that are similar to humans.
Now unfortunately, Harry Harlow did not like rhesus monkeys very much.
So in this colony of rhesus monkeys, they introduced a colony of stumptails.
So the experiment was to see, how long is it going to take for the rhesus monkeys to wipe up the cage with these less aggressive guys?
so to call it, had been adopted by the rhesus monkeys.
And inspired by Spitz's research, he wanted to conduct some research with rhesus monkeys in environments where we could sort of control the environment a little bit
Now, we been able to replicate these findings in a variety of animal models, ranging from drosophila, the fruit fly, on the left, to rhesus macaques on the right.
Now, stumptails are a little bit bigger than rhesus monkeys, but they're also much, much less aggressive.
So they took the stumptails out after a while and watched to see, how long is it going to take for the rhesus
But in order to push the limits, what he started to do was he would take the rhesus monkeys and put them in isolation chambers for three months, six
And the amounts of time actually really stop mattering, because the point is that by the time a rhesus monkey has been put in an isolation
