| experiment | Noun: A procedure done in a controlled environment for the purpose of gathering observations, data, or facts, demonstrating known facts or theories, or testing hypotheses or theories. Verb: To carry out such a procedure. (09 Oct 1997) |
|---|---|
| experimental | 1. Of, relating to or based on experience: empirical. 2. Of a disease: intentionally produced especially in laboratory animals for the purpose of study. (18 Nov 1997) |
| experimental allergic encephalitis | <pathology> An autoimmune disease that can be induced in various experimental animals by the injection of homogenised brain or spinal cord in Freund's adjuvant. The antigen appears to be a basic protein present in myelin and the response is characterised by focal areas of lymphocyte and macrophage infiltration into the brain, associated with demyelination and destruction of the blood-brain barrier. Sometimes used as a model for demyelinating diseases, although whether this is entirely justifiable is not clear. (18 Nov 1997) |

| experimental error | The total error of measurement ascribed to the conduct of an empirical observation. It is commonly expressed as the standard deviation of replicated experiments. There may be many components, including those in the sampling procedure, the measurements, injudicious choice of a model, observer bias, etc. (05 Mar 2000) |
| experimental group | A group of subjects exposed to the variable of an experiment, as opposed to the control group. (05 Mar 2000) |
| experimental medicine | The scientific investigation of medical problems by experimentation upon animals or by clinical research. (05 Mar 2000) |
| experimental method | In experimental psychology, control of environmental, physiological, or attitudinal factors to observe dependent changes in aspects of experience and behaviour. (05 Mar 2000) |
| experimental neurosis | A behaviour disorder produced experimentally, as when an organism is required to make a discrimination of extreme difficulty and "breaks down" in the process. (05 Mar 2000) |
| experimental psychology | A subdiscipline within the science of psychology that is concerned with the study of conditioning, learning, perception, motivation, emotion, language, and thinking, also used in relation to subject-matter areas in which experimental, in contrast to correlational or socio-experiential, methods are emphasized. (05 Mar 2000) |
| experimenter effects | The influence of the experimenter's behaviour, personality traits, or expectancies on the results of that person's own research. See: double blind study. (05 Mar 2000) |
| Mariotte's experiment | An experiment in which one looks fixedly with one eye (the other being closed), at a black dot on a card, on which is also marked a black cross; as the card is moved to or from the eye, at a certain distance the cross becomes invisible but appears again as the card is moved further; this proves the absence of photoreceptors where the optic nerve enters the eye. (05 Mar 2000) |

| Carr-Purcell experiment | In magnetic resonance, the multiple spin echo technique. (05 Mar 2000) |
| Weber's experiment | If the peripheral end of the divided vagus nerve is stimulated the heart is arrested in diastole. (05 Mar 2000) |
| control experiment | An experiment used to check another, to verify the result, or to demonstrate what would have occurred had the factor under study been omitted. See: control, control animal. (05 Mar 2000) |
| Scheiner's experiment | A demonstration of accommodation; through two minute holes in a card, separated from each other by less than the diameter of the pupil, one looks at a pin; at a short distance from the eye the pin appears double; as it is moved from the eye a point is found where it appears single, and beyond which it remains single for the emmetropic eye, but for the myopic eye it soon again becomes double. (05 Mar 2000) |
| hershey-chase experiment | <molecular biology> A landmark experiment done in 1952 which showed that DNA is the hereditary material. The experiment, done by Martha Hershey and Alfred Chase, involved allowing a bacteriophage which contained DNA labelled with 32P (an isotope of phosphorus) and a protein labelled with 35S (an isotope of sulphur) to attach to some bacteria. When the bacteriophages were later removed, they found that it was the 32P (and thus the DNA) that had entered the bacterial cells rather than the 35S (indicating the protein). (09 Oct 1997) |
| pulse-chase experiment | An experiment in which an enzyme, a metabolic pathway, a culture of cells, etc., interacts with a brief addition (pulse) of a labelled compound followed by its removal and replacement (chase) by an excess of unlabelled compound. (05 Mar 2000) |
| Stensen's experiment | Compression of the abdominal aorta of an animal promptly causes paralysis of the posterior portions of the body since the blood supply to the lumbar cord is almost entirely shut off. (05 Mar 2000) |
| Nussbaum's experiment | Exclusion of the glomeruli of the kidney from the circulation by ligation of the renal artery in animals, such as the frog, that have a renal portal system to maintain circulation to the tubules. (05 Mar 2000) |
| delayed reaction experiment | A method of measuring memory: a stimulus is presented and removed before the organism is permitted to respond to it; the interval during which the stimulus is absent, providing the organism responds correctly, is an indication of the length of memory. (05 Mar 2000) |
| double-blind experiment | <statistics> An experiment conducted with neither experimenter nor subjects knowing which experiment is the control; prevents bias in recording results. See: double-masked experiment. (05 Mar 2000) |
| double-masked experiment | A double-blind study conducted so neither the subject nor the observer know the identity of the control or variable. (05 Mar 2000) |
| tokamak physics experiment | <radiobiology> Smaller successor to TFTR at Princeton. Engineering design underway, construction scheduled to begin in FY 1995. (09 Oct 1997) |
| experiment |
the act of conducting a controlled test or investigation the testing of an idea; "it was an experiment in living"; "not all experimentation is done in laboratories" to conduct a test or investigation; "We are experimenting with the new drug in order to fight this disease" a venture at something new or different; "as an experiment he decided to grow a beard" try something new, as in order to gain experience; "Students experiment sexually"; "The composer experimented with a new style"

A type of research in which a researcher randomly assigns people to two or more conditions, varies the treatments that people in each condition are given, and then measures the effect on some response.
