simple logic will tell you that if they think the lowering of a larynx is dependent on a large amount of air, it follows that, as the air is released, the larynx will rise. simple observation will tell you that it is possible to raise and lower the larynx with any amount of air in one's lungs. for example, try placing your finger on your larynx and go back and forth from a spoken 'ah' to a spoken 'oo' (of course, there are numerous other ways to trigger larynx movement). you'll feel the larynx move down on 'oo'. and you can try this with lungs full and lungs empty and get the same results.

Mike,
The scientists are not saying that laryngeal movement is DEPENDENT on the breath. They are saying that their observations show that there is a relationship between the two. Just like, if we observed a large group of people, we might discover that when they got in their cars in the morning, they went to work. This doesn't mean that getting in the car is the only way they can get to work, or that going to work is the only thing they can do when they get in their car.
The point is that, for the people observed, a full breath was associated with a lower larynx. The same could be said for certain conversations and heartburn, I suppose. Obviously, the inhalation muscles do not cause the larynx to lower. However, something involved in the deep inhalation process ENCOURAGES some people to use the muscles that lower the larynx.
Hope this clears up my thoughts on the subject.
