What describes laughter that arises from an impulsive and unplanned moment?

The description of laughter arising from an impulsive and unplanned moment aligns well with the concept of spontaneity theory. This theory suggests that laughter can occur in unexpected circumstances or as a natural reaction to a sudden stimulus, often without conscious effort or planning. This type of laughter reflects the spontaneity of humor in everyday situations where something surprising or amusing occurs, prompting an immediate laugh.

In contrast, other theories focus on different aspects of humor. Incongruity theory emphasizes the unexpected juxtaposition of ideas that leads to humor, while relief theory posits that laughter is a way to release psychological tension. Superiority theory involves humor that comes from feeling a sense of superiority over others or their misfortunes. Each of these theories captures different facets of humor and laughter, but spontaneity theory specifically addresses the impulsive nature of laughter in unpremeditated moments.
