Verbal behavior refers to language from a behavioral perspective. Components of verbal behavior include echoics, mands, tacts, and intraverbals. An echoic is verbal behavior evoked and reinforced by another's verbal behavior with point-to-point correspondence. A mand is a request reinforced by obtaining the requested object or activity. A tact is a label evoked by a nonverbal stimulus and reinforced by praise. An intraverbal is verbal behavior evoked and reinforced by other verbal behavior through questions, comments, and conversation.
