Kuhn's 15 stages of laughter
I stumbled across Kuhn’s 15 stages of laughter in a paper by Ronald A. Berk (Berk, R. A. (2001). The active ingredients in humor: Psychophysiological benefits and risks for older adults. Educational Gerontology, 27:3-4, 323-339). Annoyingly, the source of the original article eludes me as it appears to be in a short-lived publication called the Journal of Nursing Jocularity.
Here are the 15 stages:
- Smirk: Slight, often fleeting upturning of the corners of the mouth, completely voluntary and controllable.
- Smile: Silent, voluntary and controllable, more perceptible than a smirk; begins to release endorphins.
- Grin: Silent, controllable, but uses more facial muscles (e.g., eyes begin to narrow).
- Snicker: First emergence of sound with facial muscles, but still controllable (if you hold in a snicker, it builds up gas).
- Giggle: Has a 50% chance of reversal to avoid a full laugh; sound of giggling is amusing; efforts to suppress it tend to increase its strength.
- Chuckle: Involves chest muscles with deeper pitch.
- Chortle: Originates even deeper in the chest and involves muscles of torso; usually provokes laughter in others.
- Laugh: Involves facial and thoracic muscles as well as abdomen and extremities; sound of barking or snorting.
- Cackle: First involuntary stage; pitch is higher and body begins to rock, spine extends and flexes, with an upturning of head.
- Guffaw: Full body response; feet stomp, arms wave, thighs slapped, torso rocks, sound is deep and loud; may result in free flowing of tears, increased heart rate, and breathlessness; strongest solitary laughter experience.
- Howl: Volume and pitch rise higher and higher and body becomes more animated.
- Shriek: Greater intensity than howl; sense of helplessness and vulnerability.
- Roar: Lose individuality; i.e., the audience roars!
- Convulse: Body is completely out of control in a “fit” of laughter resembling a seizure; extremities flail aimlessly, balance is lost, gasp for breath, collapse or fall off chair.
- Die Laughing: Instant of total helplessness; a brief, physically intense, transcendent experience; having died, we are thereafter reborn in a refreshing moment of breathlessness and exhaustion with colours more vivid and everything sparkling; everything is renewed.
