25.1 Definition of Metaphorical Extension
Metaphorical extension is a form of verbal behavior in which the response has previously been acquired and the stimulus is novel and has some, but not all, of the relevant features of the stimulus that previously controlled the response. Irrelevant features of metaphorical extension include the type of elementary verbal relationship, the formal or dynamic characteristics of the response and stimulus, and whether or not the current response is followed by reinforcement.
