Displacement

A psychological process in which feelings originating from one source are expressed outwardly in terms of concern or preoccupation with an issue or problem that the patient considers more acceptable. In some BDD patients, obsession about the body includes displaced feelings, often related to a history of childhood abuse.

displacement

(1) change in position of a body or object, including size (magnitude) and direction of change, i.e. a vector quantity. linear displacement the distance and direction between the start and end point. Contains a measure of distance (e.g. metres) and a measure of direction (e.g. an angle in degrees to the horizontal) - effectively the distance and direction 'as the crow flies'. angular displacement the angle between the start and finish positions in a rotational movement, including a direction (e.g. clockwise or anticlockwise). Measured in degrees or radians. (2) the volume of fluid (usually water) that is moved when a body or object is immersed in it. (Displacement must be distinguished from 'distance moved' which includes only magnitude and not direction.)
