Laughing is a reaction to certain stimuli. It may ensue from hearing a joke, being tickled, or other stimuli. Most commonly, it is considered a visual expression of a number of positive emotional states, such as joy, mirth, happiness, relief, etc. However on some occasions it may express other emotions, such as embarrassment, apology or confusion ("nervous laughter)" or courtesy laugh.
Laughter is a part of human behavior regulated by the brain, helping humans clarify their intentions in social interaction and providing an emotional context to conversations. Laughter is used as a signal for being part of a group — it signals acceptance and positive interactions with others. Laughter is sometimes seen as contagious, and the laughter of one person can itself provoke laughter from others as a positive feedback. This may account in part for the popularity of laugh tracks in situation comedy television shows.
Laughter is anatomically mediated by the epiglottis constricting the larynx.
The study of humor and laughter, and its psychological and physiological effects on the human body, is called gelotology.
