A displacement activity is the result of two contradicting instincts in a particular situation. Birds, for example, may peck at grass when uncertain whether to attack or flee from an opponent similarly, a human may scratch his or her head when they do not know which of two options to choose. Displacement activities often involve actions to bring comfort such as scratching, drinking or feeding. The first description of a displacement activity though not the use of the term is probably by Julian Huxley in 1914. ref Huxley J. 1914.

This article discusses a concept in sociology. For the concept in physics, see time dilation . Time displacement in sociology refers to the idea that new forms of activities may replace older ones. New activities that cause time displacement are usually technology based, most common are the information and communication technologies such as Internet and television . Those technologies are seen as responsible for declines of previously more common activities such as in and out of home socializing, work, and even personal care and sleep. For example, Internet users may spend time online using it as a substitute of other activities that served similar function watching television, reading printed media, face time face to face interaction, etc. . Internet is not the first technology to result in time displacement. Earlier, television had a similar impact, as it shifted people s time from activities such as listening to radio , going to movie theater s or, talking in house, or spending time outside it.
