All languages have dialects.

The naturalistic approach is a “learner-centered” approach that prioritizes the use of recasts and mand-models over structured drill to improve functional intelligibility in conversational contexts.

 Spanish and English have the same number of vowels and consonants.

A clinician is working with a 5-year-old child who exhibits the phonological process of Stopping, substituting [p] for /f/. To establish the correct production of the target phoneme, the clinician provides the following instructions: “Touch your lower lip with your top teeth and blow. Watch the feather move while you keep the air going.” Which of the following best categorizes this specific clinical approach and the physiological goal of using the feather as a visual aid?
