JLB1568 | ‘Monkey Ladder Banana’ Experiment and Primary Sources
In this video I explain the importance of using primary sources to support ones claims, and focus on the example of the oft-cited ‘Monkey Ladder Banana’ experiment. This experiment involved five monkeys in a cage who were all sprayed with water if any of them climbed a ladder to get bananas; soon they learned to physically harm any fellow monkey who tried to climb the ladder, and this custom was passed on even to new monkeys entering the cage who had never been sprayed with water.
