BrainStuff Season 2 Episode 19 Do Animals Laugh?

Do Animals Laugh? This is the question that has puzzled humans for decades. In this episode of BrainStuff, host Lauren Vogelbaum explores the science behind the elusive behavior of animal laughter.

Lauren starts off by acknowledging the fact that laughter is a universal behavior among humans, and it is often associated with positive emotions such as joy and happiness. However, laughter is not limited to humans, and various studies suggest that animals too can experience this emotion. From chimpanzees to dolphins, the animal kingdom is full of examples of animals that seem to exhibit behavior that is similar to our own laughter.

So, how can we tell if animals are really laughing? Lauren delves into the latest scientific research on animal laughter, starting with the work of Dr. Marina Davila Ross, a psychologist at the University of Portsmouth. Dr. Ross studies primate laughter and has conducted experiments that demonstrate that chimpanzees can indeed laugh. She has observed that chimpanzees have the ability to produce a specific type of vocal sound that is closely associated with laughter in humans. Furthermore, they seem to laugh more when they are tickled, which is a behavior that is often associated with human laughter.

Lauren also discusses the work of Dr. Peter J. Panksepp, a neuroscientist who has studied laughter in rats. Dr. Panksepp discovered that rats emit an ultrasonic vocalization when they are tickled, which can be interpreted as a form of laughter. He also found that tickling can increase the level of dopamine in the rats' brains, which is a neurotransmitter associated with pleasure and reward.

Moving on from primates and rats, Lauren explores other examples of animal laughter. She talks about the playful behavior of dolphins, which often involves a series of vocalizations that could be interpreted as laughter. She also mentions the laughing kookaburra bird, which is known for producing a unique vocal sound that sounds eerily similar to human laughter.

But why do animals laugh? This is a difficult question to answer, but Lauren discusses some of the theories that have been put forward. One theory is that laughter is a social behavior that helps to strengthen social bonds within a group of animals. Another theory is that laughter is a way for animals to communicate their well-being and comfort to other members of their group. Whatever the reason, it is clear that animal laughter is a fascinating field of study that reveals much about the complex emotional lives of animals.

Lauren also touches on some of the ethical implications of studying animal laughter, particularly in relation to animal captivity and experimentation. She acknowledges that while studying animal laughter can provide valuable insights into the minds and emotions of animals, it is important to do so in an ethical and respectful manner.

In conclusion, Do Animals Laugh? is a fascinating episode of BrainStuff that provides a glimpse into the world of animal laughter. From primates to rats, dolphins to kookaburras, animals exhibit behavior that is strikingly similar to human laughter. Through the latest scientific research, we are beginning to better understand the importance and complexity of this behavior, and the episode serves as a reminder that animals are not so different from us after all.
