| 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) |
