chrono-, chron- +

A branch of chronobiology concerned with the effects of drugs upon the timing of biological events and rhythms, and the relation of biological timing to the effects of drugs.

1. A device that generates standard time signal pulses from a clock or other timing mechanism.
2. An apparatus for the distribution of electric time-signals.

A paraphilia in which sexual satisfaction depends on the age of the partner; most frequently, the partner must be of a greatly different age than the subject (chronophilic disparity). The term includes ephebophilia (adolescents are the sexual object), gerontophilia (the partner must be older, of parental or grandparental age), nepiophilia (infants), and pedophilia (juveniles).

1. Discomfort concerning the duration or immensity of time (a common psycho-neurosis of prison inmates).
2. It may be the most common anxiety disorder in prison inmates and is known as, "stir crazy"; by inmates.

As stated in the definition above, this is considered the most common psychiatric disorder in prison inmates, and sooner or later almost all prisoners suffer chronophobia to some degree; it occurs in every potential neurotic who goes to prison.

After the novelty of prison has worn off and the real length of the sentence is felt, chronophobia sets in. The prisoner goes into a panic, usually while in his cell, and fears his enclosure and restraint, but this apparent claustrophobia arises from fear of time, as represented by the prison.

Following early anxieties, the prisoner may become essentially a phlegmatic, indifferent automaton who serves the rest of his sentence by the clock and lives wholly in the present, one day at a time.

Chronophobia is characterized by panic, anxiety, and claustrophobia which is exhibited by prisoners having difficulty adjusting to long prison sentences.

A photograph taken as one of a series for the purpose of showing successive phases of a motion.

An early term for cinematic photography.

An instrument for observing and the precise measuring of minute time intervals of extremely brief periods of time.

Observation and exact measurement of time.

Employing intervals of time with a fixed significance (as in a system of signaling) by exposing visual objects or sounding audible signals for selected intervals of time.

1. A species which is represented in more than one geological time horizon.
2. The successive species replacing each other in a phyletic lineage which are given ancestor and descendant status according to the geological time sequence.
3. Any species for which there is paleontological evidence throuh a period of time.

An instrument formerly used for study of the rhythms of the pulse.

The study of geologic history based on the age of rock strata and their time sequences.

Distortion or confusion of the sense of time; as for dates, seasons of the year, times of day, and over estimation or under estimation of the duration of time.

The treatment of certain sleep disorders by capitalizing on the natural phase delay in adults; the bedtime is successively advanced by one to several hours each day until the individual can retire, sleep, and arise at appropriate times.

Relating to time and temperature.
