Fear of the dark
From Wikipedia, the free encyclopedia
The fear of the dark is a common fear among children and to a varying degree is observed for adults. The pathological fear of the dark is sometimes called nyctophobia (from Greek νυξ nic-to-pho-bi-a: "night" and phobia), scotophobia, from σκότος - "darkness", or lygophobia, from lyge - "twilight".
The fear of the dark is heightened by imagination: a stuffed toy may appear a monster in the dark. Nightmares contribute to the fear of the dark as well: after waking up because of nightmare the child may refuse to go to bed without lights on. Fear of dark is a phase of child development.[1] Most observers report that fear of the dark seldom appears before the age of 2 years.[2] Fear of the dark is not fear of the absence of light, but fear of possible or imagined dangers concealed by the darkness.[3]
Some researchers, beginning with Sigmund Freud[4] consider the fear of the dark as a manifestation of separation anxiety.[citation needed]
In the 1960s scientists conducted experiments to discover molecules responsible for memory. In one experiment rats, normally nocturnal animals, were conditioned to fear the dark and a substance, called scotophobin that was apparently responsible for remembering this fear was extracted from rats' brains. Subsequently these findings were debunked.[5]
