They should put the kids by themselves without their parents in the room. The test might be wrong because they could have noticed but just wanted their parents attention. Plus the orangutans were alone, so the kids should be too. Also they should use same age orangutans instead of any age. In the video they did not mention the orangutans age. However, they mentioned the kids’ ages. So this could be inaccurate because if the orangutans were older than their brains might have been more developed than a 2 or 3 year old human. Lastly they should use the same number of animals in each test to see if it is accurate.
Some good things about the test is they used a 3 year old to see if there was any difference between them and many 2 year olds. They also used 2 different animals.
Their data could be accurate, but they should run more tests on the subjects.

Great points! A larger sample size gives more robust conclusions.
