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 preexperiment base rate.
