The portrayal of operant conditioning in the popular sitcom "Big Bang Theory" quite accurately depicts the simplicity of said phenomenon in psychology. One of the characters simply offers another character a piece of chocolate each time she does something acceptable... she is un-knowingly being trained during this process. This may seem like a very bare-bones, simplistic example of how operant conditioning can be utilized, but it is also very accurate. Today the world of animal training completely revolves around this concept of positive reinforcement to shape an animals behaviors.
Dolphin trainers at Sea World live by this theory and their efforts pay off each time they perform a show. I find it very interesting that such an elementary concept is so effective. Something that takes five minute for a sitcom to introduce, humorously, can be directly applied to real life situations. As long as the specimens: the character or dolphins, are presented with a stimulus that ignites the response of pleasure/enjoyment: chocolate or a rub on the belly, the training is almost inevitable. These dolphins perform amazing feats and obey their trainers unbelievably well. I find enjoyment in discovering psychological ideas being implemented in the world around me.
