disorder is a communication disorder that involves discontinuous flow and
timing of speech. It is mostly seen in children who are learning to speak. Physical
tension, negative reactions, and avoiding of speaking situations work together
with this disorder. Individuals with this disorder display repetition of words,
sound extensions and long pauses when speaking. For the question given above, a
12-year-old student who says "i-i-i-i want i-i-i-ice c-c-c-cream" is

Im not sure but if you think of it, the one that you didn't put any salt is a independent variable because it doesn't really rely on anything it doesn't have salt. The Dependent variable would be the 2nd and the 3rd cup because it doesn't have much salt but the 4th cup has lots of salt so its basically controlled. Hope it helps !
