Laughter is a very common non-verbal expression of emotion. Often associated with amusement and humour, laughter is more commonly produced for purely social and communicative reasons; within communicative settings it can be used in highly complex and nuanced ways. In this talk I will explore the evolution, acoustic and neural origins of laughter, and explore some of the complexities of its use in interactions.
