Understanding Voluntary and Involuntary Laughter and Its Social Role
Laughter often serves social functions beyond amusement, occurring more frequently in the presence of others, especially familiar companions. It promotes bonding through contagious effects and helps reduce stress. Typical conversational laughter is short and voluntary, while uncontrollable, involuntary laughter is longer, higher pitched, and harder to suppress. Examples include situations where laughter becomes uncontrollable despite inappropriate timing, illustrating different brain mechanisms behind voluntary and involuntary laughter.
