Transcript of Biology of Laughter Tee Hee XD Woo Hoo! Ayayayayayayayayaaaa

- mammals laugh too, just in different ways

- rats' chirps resemble our giggles

- hyenas, dogs, dolphins

- Dr. Balcombe: there are 2 kinds - tickle-induced and from some kind of verbal trigger Do Other Animals Laugh? By: Inna Lucero, Michelle Pham, Elia Martinez, Janella Manalang What is Laughter? Physiology of Laughter The Evolution of Laughter Physical Health Benefits Laughter triggers the release of endorphins.

Laughter protects the heart.

Laughter boosts the immune system. Mental
Health Benefits Endorphins?! In the Brain Gelotology: The study of laughter and it's effects on the human body -Laughter triggers different parts of the body and brain.
-Different chemical reactions throughout the body. What parts of the body is affected during laughter? -Hormones are released to reduce stress levels such as hormones of:
>Cortisol
>Epinephrine
-Increase health-enhancing hormones:
>Endorphins - laughter evolved as brain evolved

- was thought to have come about 7 million years ago

- innate in all humans, babies laugh before they can even talk

- even cavemen laughed during the Stone Age

- social brain hypothesis : brain evolved not for problem solving but for coping mechanisms, like laughter

- is laughter itself adaptive? -muscular exertions involved in laughing trigger increase in endorphins

- Robin Dunbar experiments:

-comedic videos
-tested before & after
-subjected to pain
- results
-pain resistance used
as indicator of
endorphin levels A study conducted at the University of Maryland School of Medicine found that 95 percent of the volunteers experienced increased blood flow while watching a funny movie, while 74 percent had decreased blood flow during a heavier picture. Increased Blood Flow Lobes -Left side cortex
-Frontal lobe
-Right side cortex
-Occipital lobe
-Motor Sections Adds JOY and ZEST to life!

Relieves stress!

Improves mood!

Enhances resilience! Limbic System -Amygdala
-Hippocampus
-Thalamus Theories of Laughter Incongruity Theory Superiority Theory Relief Theory Incongruity Theory Superiority Theory Relief Theory Movie makers have been using this basis for a long time. Describe humor relating to tension release A Cognitive Process Pattern Recognition Theory: When a situation/movie/story creates tension within ourselves, we need to find a way to release this feeling of tension and incongruity. - laughter vs. humor

- laughter's function as a "weapon of our cognitive arsenal"

- finding amusement in patterns we recognize

- we are attracted to people who laugh Laughter serves as that release of emotions and thoughts. In an action or thrillers, comic relief is often used following extremely tense situations. Whats so funny? "comes into play when we laugh at jokes that focus on someone else's mistakes, stupidity or misfortune." "We feel superior to this person, experience a certain detachment from the situation and so are able to laugh at it." Theory dates back to Aristotle, Plato and Thomas Hobbes' Leviathan -Muscles in the face contracts
-Sound is activated:
>Epiglottis
>Larynx
-Tear ducts
-Abdominal muscles
-Back muscles
-Arm and leg muscles
-Heart pumps harder and faster
>Blood flow increase
>Promote a healthier immune system Throughout the Body Sigmund Freud and Herbert Spencer were the most prominent relief theorist. Example:
A woman goes into a cafe with a duck. She puts the duck on a stool and sits next to it. The waiter comes over and says: “Hey! That's the ugliest pig that I have ever seen.” The woman says: “It’s a duck, not a pig.” And the Waiter says: “I was talking to the duck.” "suggests that humor arises when logic and familiarity are replaced by things that don't normally go together." Most popular answer to why we find things funny. Expecting a certain outcome, but instead, getting a unexpected one makes jokes funny. you have a "set up" and a "punch line". The set up comes first and creates an expectation. The punch line "violates that expectation". The anticipation of the jokes fuels emotions, but when the joke takes a turn new emotions are fueled. "We experience this incongruity between the different parts of the joke as humorous." Example: Two fish in a tank.
One turns to the other and says: “Do you know how to drive this?”
