Which type of training involves fill-ins for songs and nursery rhymes using backward chaining?

The correct response is related to intraverbal training because this method targets the ability to engage in conversation or respond to questions using verbal behavior. In the context of fill-ins for songs and nursery rhymes, intraverbal training encourages individuals to complete phrases or sentences, which requires them to recall information and produce verbal responses based on cues that are provided.

When performing backward chaining, the trainer typically starts with the last part of the sequence (in this case, the ending of a song or rhyme) and builds backward, allowing the learner to gradually learn each component. This approach is especially effective in intraverbal training because it scaffolds learning by ensuring the individual can successfully respond to a prompt with the correct completion, reinforcing their ability to engage in dialogue that is contextually relevant.

In contrast, echoic training focuses on the imitation of sounds or words heard, mand training is centered around requesting behaviors, and tact training involves labeling items or actions. These approaches do not specifically involve the interactive completion of phrases or song lyrics in the same way that intraverbal training does. Thus, intraverbal training aligns perfectly with the fill-in-the-blank format that is integral to this type of expressive language development.
