Tickling is the act of touching a part of the body, so as to cause involuntary twitching movements or laughter. Such sensations can be pleasurable or exciting, but are sometimes considered highly unpleasant, particularly in the case of relentless heavy tickling. The word "tickle"&_160;(helpยทinfo) evolved from the Middle English tikelen, perhaps frequentative of ticken, to touch lightly. The idiom tickled pink means to be pleased or delighted.[1] In 1897 psychologists G. Stanley Hall and Arthur Allin described a "tickle" as two different types of phenomena.[2] The first is a sensation caused by very light movement across the skin. This type of tickle, called knismesis, generally does not produce laughter and is sometimes accompanied by an itching sensation. The second type of tickle is the laughter inducing, "heavy" tickle, produced by repeatedly applying pressure to "ticklish" areas, and is known as gargalesis. The feather-type of tickle is often elicited by crawling animals and insects, such as spiders, mosquitoes, scorpions or beetles, which may be why it has evolved in many animals. Gargalesis reactions, on the other hand, are thought to be limited to humans and other primates; however, some research has indicated that rats can be tickled as well.[3]
