Definition
An intraverbal is a verbal response evoked by another person's verbal behavior, where the response does not match the form of the stimulus. Answering 'a dog' to 'what barks?', filling in 'twinkle twinkle little ___', and conversational exchanges are all intraverbals.
Intraverbal repertoires are central to conversation and academic skills and are typically targeted after mands, tacts, and listener skills are established.
