conditioned response(redirected from conditioned reflexes)
Also found in: Dictionary, Thesaurus.
a response that does not occur naturally in the animal but that may be developed by regular association of some physiologic function with an unrelated outside event, such as ringing of a bell or flashing of a light. Soon the physiological function starts whenever the outside event occurs. Called also conditioned reflex. See also conditioning.
1. The process of acquiring, developing, educating, establishing, learning, or training new responses in an individual. Used to describe both respondent and operant behavior; in both usages, refers to a change in the frequency or form of behavior as a result of the influence of the environment.
2. The application of a structured training program to prepare cardiovascular, muscular, and psychological readiness in human, canine, and equine athletes for competition or strenuous events.
con·di·tioned re·flex (CR),
a reflex that is gradually developed by training and association through the frequent repetition of a definite stimulus. See: conditioning.
A new or modified response elicited by a stimulus after conditioning. Also called conditioned reflex.
an automatic reaction learned through training to a stimulus that does not normally elicit such response. Such responses can be physical or psychological and are produced by repeated association of some physiological function or behavioral pattern with an unrelated stimulus or event. In Pavlov's classic experiments, dogs learned to associate the sound of a ringing bell with feeding time so that they salivated at the sound of the bell, regardless of whether or not food was given to them. Also called acquired reflex, behavior reflex, conditioned reflex, trained reflex. Compare unconditioned response. See also classical conditioning, operant conditioning.
con·di·tioned re·sponse(kŏn-dish'ŭnd rĕ-spons')
educated by a conditioning process. See conditioning.
the pairing of a neutral stimulus with a primary, or natural, reinforcer.
a response that does not occur naturally in the animal but that may be developed by regular association of some physiological function with an unrelated outside event, such as ringing of a bell or flashing of a light. Soon the physiological function starts whenever the outside event occurs. Called also conditioned reflex. See also conditioning.
any action or change of condition evoked by a stimulus.
the immune response in which antibodies or immune lymphoid cells are produced against the body's own tissues.
shining a bright light in the eye causes a blink. Called also dazzle reflex.
galvanic skin response
the alteration in the electrical resistance of the skin associated with sympathetic nerve discharge.
specifically altered reactivity of the animal body after exposure to antigen, manifested as antibody-production, cell-mediated immunity, development of hypersensitivity, or as immunological tolerance. Called also immune reaction. See also immune response.
a test of vision for animals.
see placing reflex.
in surveys, the number of completed survey instruments (questionnaires, interview records) divided by the total number of persons approached.
a field trial conducted to test a hypothesis, often about the cause of a disease but can encompass therapeutics or control of a disease. The hypothesis is tested by observing the response to an alteration in the system, e.g. in feeding or in management.
triple response (of Lewis)
a physiological reaction of the skin to stroking with a blunt instrument: first a red line develops at the site of stroking, owing to the release of histamine or a histamine-like substance, then a flare develops around the red line, and lastly a wheal is formed as a result of local edema.
an unlearned response, i.e. one that occurs naturally. See also conditioning.
