(565) The evolution and functions of laughter and humor: a synthetic approach.   Gervais M and Wilson DS.   2005.   The Quarterly Review of Biology, volume 80, pages 395-430.   With reference to working memory, emotional laughter, eponymously referred to as Duchenne laughter (see this reference, page 396, and reference 286, page 2122), may occur some time after the humorous stimulus, because working memory has enabled reverberation of the stimulus until there has been time for a reflective chuckle. Self-generated and emotionless laughter may be associated with stimuli by chance, or by personal meaning, as in the wry, sardonic sigh.
