quick-motion phenomenon
   Also known as time-grabbing phenomenon. The term quick-motion phenomenon is a loose translation of the German expression Zeitrafferphänomen, literally 'time shortening phenomenon' or 'time abridgement phenomenon'. The term Zeitrafferphänomen was introduced in or shortly before 1934 by the Austrian neurologists Otto Pötzl (1877-1962) and Hans Hoff (1897-1969). It is used to denote a rare variant of *tachypsychia (which is itself classified as a type of *time distortion) in which psychological time is significantly speeded up. As a result, time seems to pass too quickly, and people and objects are perceived as if rushing about at an extraordinary speed. The quick-motion phenomenon has been described chiefly with reference to the visual modality, but it can also affect the auditory modality. In the latter case, people may seem to be talking too fast and too loud, in high-pitched voices, like an audio tape played at fast forward. The accompanying sensation that one's own movements are slowing down is called a * slow-motion hallucination. The quick-motion phenomenon was decribed as early as 1917 in an 8-year-old boy with fever by a German psychiatrist called Klien. Historically, the phenomenon has been associated primarily with temporal lobe dysfunction. However, emerging empirical evidence would seem to indicate that the neurobio-logical correlates of time perception are located within an extensive network that includes the right parietal lobe, the basal ganglia, and the cerebellum. Etiologically, the quick-motion phenomenon is associated primarily with *aurae occurring in the context of paroxysmal neurological disorders such as migraine and epilepsy, the * Alice in Wonderland syndrome, and the use of psychotomimetic substances such as cannabis, LSD, and mescaline. The term quick-motion phenomenon is used in opposition to the terms slow-motion hallucination and *protracted duration. It should not be confused with the notions of *akinetopsia and * cinematographic vision, which denote conditions in which the ability to perceive movement is lacking, and moving objects are therefore perceived in the form of a series of 'stills'. Nor should it be confused with the notion of * temporal compression, which refers to the retrospective sensation that time has passed too quickly.
