The correct answer is C. Using a mand-to-tact transfer procedure.
Explanation:
The mand-to-tact transfer procedure is a strategy that can bring vocalizations under the control of a nonverbal stimulus from a motivating operation. This procedure involves the following steps:
1. The learner is first taught to mand (request) for the target item using a specific vocal response.
2. Once the learner reliably mands for the target item, the practitioner then shifts the reinforcer from the target item to a generalized conditioned reinforcer, such as praise or a token.
3. The practitioner then presents the target item as a nonverbal stimulus and prompts the learner to tact (label) the item using the same vocal response that was previously used to mand for it.
4. Through this process, the vocalization becomes under the control of the nonverbal stimulus, rather than solely the motivating operation.
The other options are not correct:
A. Using a mand frame is a different teaching strategy that focuses on teaching the learner to request items using specific verbal frames (e.g., "I want ___").
B. "All options are correct" is not the correct answer, as only one of the options represents the specific strategy described in the question.
D. Shifting the reinforcer from the target item to a generalized conditioned reinforcer is a step within the mand-to-tact transfer procedure, but it is not the complete strategy.
