|---|---|
| contact lens solutions | Sterile solutions used to clean and disinfect contact lenses. (12 Dec 1998) |
| air conditioning | The maintenance of certain aspects of the environment within a defined space to facilitate the function of that space; aspects controlled include air temperature and motion, radiant heat level, moisture, and concentration of pollutants such as dust, microorganisms, and gases. (12 Dec 1998) |
| assertive conditioning | A form of behaviour modification or therapy in which a client is taught to feel free to make legitimate demands and refusals in situations which previously elicited diffident responses. Synonym: assertive conditioning. (05 Mar 2000) |
| aversive conditioning | <psychology> A form of behaviour training or modification in which a noxious event is used to punish or extinguish undesirable behaviour. See: aversion therapy. Synonym: aversive conditioning. (05 Mar 2000) |
| avoidance conditioning | The technique whereby an organism learns to avoid unpleasant or punishing stimuli by learning the appropriate anticipatory response to protect it from further such stimuli. Compare: escape conditioning. Synonym: avoidance training. (05 Mar 2000) |
| pavlov conditioning | The Russian physiologist Ivan petrovich pavlov (1848-1936) conditioned dogs to respond in what proved to be a predictable manner, for example, by first ringing a bell before feeding them and then simply ringing the bell upon which stimulus they would begin to salivate as if they were about to eat. (12 Dec 1998) |
| pavlovian conditioning | A type of conditioning, first studied by I. P. Pavlov, in which a previously neutral stimulus (bell sound) elicits a response (salivation) as a result of pairing it (associating it contiguously in time) a number of times with an unconditioned or natural stimulus for that response (food shown to a hungry dog). Synonym: pavlovian conditioning. (05 Mar 2000) |
| respondent conditioning | A type of conditioning, first studied by I. P. Pavlov, in which a previously neutral stimulus (bell sound) elicits a response (salivation) as a result of pairing it (associating it contiguously in time) a number of times with an unconditioned or natural stimulus for that response (food shown to a hungry dog). Synonym: pavlovian conditioning. (05 Mar 2000) |
| classical conditioning | <psychology> Learning that takes place when a conditioned stimulus is paired with an unconditioned stimulus. (12 Dec 1998) |
| physical conditioning, animal | Physical conditioning of domestic, laboratory, and zoo animals. Includes exercising of animals. (12 Dec 1998) |
| wall conditioning | <radiobiology> Describes a class of procedures used to control the composition of materials adsorbed onto the walls of a plasma device. Conditioning is important because material from the walls can create impurities in the plasma, and these impurities typically degrade plasma performance. See: boronisation, impurity control, electron cyclotron discharge cleaning. (09 Oct 1997) |
| conditioning | 1. <psychology> A general term referring to the learning of some particular response. 2. <oncology> A preparative regimen of chemotherapy before a bone marrow transplant. (03 Jul 1999) |
| conditioning, eyelid | Reflex closure of the eyelid occurring as a result of classical conditioning. (12 Dec 1998) |
| conditioning, operant | Learning situations in which the sequence responses of the subject are instrumental in producing reinforcement. When the correct response occurs, which involves the selection from among a repertoire of responses, the subject is immediately reinforced. (12 Dec 1998) |
