I was searching some of the behaviour experiments when I remembered one which is going viral through social networking websites. The Monkeys, ladder and banana experiment which demonstrates the learned helplessness behaviour is summarised as in the image below.
In this article "What Monkeys Can Teach Us About Human Behavior: From Facts to Fiction" by Dario Maestripieri, Ph.D. I found that this experiment never happened and it was nearly invented by Michael Michalko and it was only an inspiration from an old research.
It was a little confusing for me but I learnt one lesson from this story, search for the scientific references and sources and never go after viral myths on the social networking websites.
