DARWIN-HECKER HYPOTHESIS OF LAUGHTER/HUMOR. This proposition -named after the English naturalist Charles Darwin and the German physiologist Ewald Hecker - states that humor and laughter (laughter induced by tickling) have common underlying mechanisms. In one test of the Darwin-Hecker hypothesis (Harris & Christenfeld, 1997), participants were tickled before and after viewing comedy videotapes; results showed that those who exhibited more pronounced laughter to comedy also laughed more vigorously to being tickled. However, there was no evidence that comedy-induced laughter increased subsequent laughter to tickle, nor that ticklish laughter increased laughter to comedy. Thus, it is suggested that humor and tickle are related only in that the two behaviors share a final threshold for elici-tation of their common behavioral response (smiling and laughing), and the possibility is not ruled out that humor develops ontogeneti-cally from tickling - but that after such a development has taken place, the two behaviors may share only a final common pathway. It may be possible, also, that tickle shares an internal state with other emotions (such as social anxiety), and that ticklish laughter might be more similar to nervous, rather than to mirthful, laughter.
