Definitions for "EXTINCTION"
The act of extinguishing or making extinct; a putting an end to; the act of putting out or destroying light, fire, life, activity, influence, etc.
State of being extinguished or of ceasing to be; destruction; suppression; as, the extinction of life, of a family, of a quarrel, of claim.
The ceasing to exist of a species of living organism, such as a plant or animal, whose numbers declined to the point where the last member of the species died and therefore no new members of the species could ever again be born.
The dimming of starlight as it passes through the interstellar medium.
The attenuation of light.
A dimming of the light of an object, by virtue of material lying between it and the observer, which scatters or absorbs part of that light. Usually refers to such a reduction caused by our own atmosphere, or by clouds of gas and dust in interstellar space.
The non-reinforcement of a previously reinforced response. This procedure involves ignoring the behavior or withholding reinforcement for a previously reinforced response. In all cases, when inappropriate behavior is being ignored, another behavior which is appropriate should be reinforced. Extinction is a technical procedure that requires staff training. This is a level I procedure.
In operant conditioning, return of a response to the baseline level when the response is no longer reinforced. (28)
1. in classical conditioning, the gradual disappearance of the conditioned response when the conditioned stimulus is repeatedly presented without being paired with the unconditioned stimulus. 2. in operant conditioning, the gradual disappearance of a response that is no longer followed by a reinforcer. (240, 252)
complete annihilation; "they think a meteor cause the extinction of the dinosaurs"
Process of becoming extinct; the end of a particular lifeform or evolutionary line; the extinction of the dinosaurs occurred 65 million years ago.
The elimination of all individuals in a group by natural (dinosaurs, trilobites) or human-induced (dodo, passenger pigeon) means.
"Extinction" is the title of an episode of Star Trek: Enterprise from the third season. It first aired on September 24, 2003.
"Extinction" is the third episode of the third season of the WB original series, Smallville. The episode was written by Todd Slavkin and Darren Swimmer and was directed by Michael Kattleman. It originally aired on October 15, 2003.
The dark gray to black portion of a face-up gemstone that does not refract light; usually caused by off-axis refraction.
The term refers to blockage of light transmission through an analyzer (polarizer) in polarized and DIC optical microscopy. This condition occurs when the vibrational plane of the electric vector in a linearly polarized wavefront is oriented perpendicularly with respect to the transmission axis of the analyzer. If two Polaroid filters are held together with their transmission axes crossed, extinction is said to occur when the magnitude of light transmission drops to a minimum. The extinction factor is defined as the ratio of light amplitudes when the electric vector of a linearly polarized wavefront and the transmission axis of the analyzer are parallel (maximum transmission) and crossed (extinction or minimum transmission).
Dark or black spots in a colored stone.
