| higher order conditioning | The use of a previously conditioned stimulus to condition further responses, in much the same way unconditioned stimuli are used. (05 Mar 2000) |
|---|---|
| second-order conditioning | The use of a previously successfully conditioned stimulus as the unconditioned stimulus for further conditioning. (05 Mar 2000) |
| skinnerian conditioning | A type of conditioning developed by Skinner in which an experimenter waits for the target response (head scratching) to be conditioned to occur (emitted) spontaneously, immediately after which the organism is given a reinforcer reward; after this procedure is repeated many times, the frequency of emission of the targeted response will have significantly increased over its pre-experiment base rate. See: schedules of reinforcement. Synonym: skinnerian conditioning. (05 Mar 2000) |
| instrumental conditioning | Conditioning in which the response is a prerequisite to achieving some goal; often used as a synonym for operant conditioning, but some psychologists make distinctions in the usages of these two terms. (05 Mar 2000) |
| operant conditioning | A type of conditioning developed by Skinner in which an experimenter waits for the target response (head scratching) to be conditioned to occur (emitted) spontaneously, immediately after which the organism is given a reinforcer reward; after this procedure is repeated many times, the frequency of emission of the targeted response will have significantly increased over its pre-experiment base rate. See: schedules of reinforcement. Synonym: skinnerian conditioning. (05 Mar 2000) |
| tissue conditioning (dental) | The use of a treatment material (tissue conditioner) to re-establish tone and health to irritated oral soft tissue, usually applied to the edentulous alveolar ridge. (12 Dec 1998) |
| trace conditioning | Conditioning when there is no temporal overlap between the conditioning stimulus and the unconditioned stimulus. (05 Mar 2000) |
| transplantation conditioning | Preparative treatment of transplant recipient with various conditioning regimens including radiation, immune sera, chemotherapy, and/or immunosuppressive agents, prior to transplantation. Transplantation conditioning is very common before bone marrow transplantation. (12 Dec 1998) |
| escape conditioning | The technique whereby an organism learns to terminate unpleasant or punishing stimuli by making the appropriate new response which stops the delivery of such stimuli. Compare: avoidance conditioning. Synonym: escape training. (05 Mar 2000) |
| abscess, skin | Medical term for a common boil. (12 Dec 1998) |
| allergy skin test | Test done on the skin to identify the allergy substance (allergen) triggering the allergic reaction. A small amount of the suspected allergy substance is placed on the skin. The skin is then gently scratched through the small drop with a special sterile needle. If the skin reddens and, more importantly, swells, then allergy to that substance is probable. (12 Dec 1998) |
| alligator skin | <dermatology> A group of cutaneous disorders characterised by increased or aberrant keratinisation, resulting in noninflammatory scaling of the skin. Many different metaphors have been used to describe the appearance and texture of the skin in the various types and stages of ichthyosis, for example alligator, collodion, crocodile, fish and porcupine skin. most ichthyoses are genetically determined, while some may be acquired and develop in association with various systemic diseases or be a prominent feature in certain genetic syndromes. The term is commonly used alone to refer to i. Vulgaris. (18 Nov 1997) |
| appendages of skin | The hairs, nails, and sweat, sebaceous, and mammary glands. (05 Mar 2000) |
| aspergillus antigen skin test | <investigation> An antigen, prepared from aspergillus, is injected into the skin. In 48 to 72 hours the site is read as positive or negative. A positive skin test (inflammation at the test site) indicates prior exposure to aspergillus and therefore a risk for developing aspergillosis. (27 Sep 1997) |
| bronzed skin | The dark skin in Addison's disease. (05 Mar 2000) |
