laughter
Laughing is a reaction to certain stimuli. Traditionally, it is considered a visual expression of happiness, or an inward feeling of joy.[citation needed] It may ensue from hearing a joke, being tickled, or other stimuli.
Laughter is a part of human behavior regulated by the brain, helping humans clarify their intentions in social interaction[citation needed] and providing an emotional context to conversations.[citation needed] Laughter is used as a signal for being part of a group — it signals acceptance and positive interactions with others.[citation needed] Laughter is sometimes seen as contagious, and the laughter of one person can itself provoke laughter from others as a positive feedback.[1] This may account in part for the popularity of laugh tracks in situation comedy television shows.[citation needed]
Laughter is anatomically caused by the epiglottis constricting the larynx.[citation needed]
The study of humor and laughter, and its psychological and physiological effects on the human body, is called gelotology
