Laugh vs. Smile

By Jaxson

Main Difference

The main difference between Laugh and Smile is that the Laugh is a expression of amusement and Smile is a conscious or subconscious facial muscular movement conveying mirth or pleasure

  • Laugh

    Laughter is a physical reaction in humans and some other species of primate, consisting typically of rhythmical, often audible contractions of the diaphragm and other parts of the respiratory system. It is a response to certain external or internal stimuli. Laughter can arise from such activities as being tickled, or from humorous stories or thoughts. Most commonly, it is considered a visual expression of a number of positive emotional states, such as joy, mirth, happiness, relief, etc. On some occasions, however, it may be caused by contrary emotional states such as embarrassment, apology, or confusion such as nervous laughter or courtesy laugh. Age, gender, education, language, and culture are all factors as to whether a person will experience laughter in a given situation.

    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.

    The study of humor and laughter, and its psychological and physiological effects on the human body, is called gelotology.

  • Smile

    A smile is a facial expression formed primarily by flexing the muscles at the sides of the mouth. Some smiles include a contraction of the muscles at the corner of the eyes, an action known as a “Duchenne smile”. Smiles performed without the eye contraction may be perceived as insincere.

    Among humans, smiling is an expression denoting pleasure, sociability, happiness, joy or amusement. It is distinct from a similar but usually involuntary expression of anxiety known as a grimace. Although cross-cultural studies have shown that smiling is a means of communication throughout the world, there are large differences among different cultures, with some using smiles to convey confusion or embarrassment.
