The other day, while driving, I was listening to an interesting piece on NPR. The topic escapes me now, but that may be due to the fact that no matter how interesting the interview was, I had to change stations.
It takes a fair bit to evoke this sort of reaction from me, but the interviewee pushed the right button to have me pushing the radio button. The woman being interviewed, from some university or other, spoke with a significant degree of uptalk, also known as moronic interrogative. That is, ending almost all of her sentences as if they were questions. This affectation has grown out of the California Valley Girl phenomenon of the early 1980s.
At one time it was limited to communication between young girls, but has now crossed gender lines and, if the NPR interview is any indication, has made its way into the field of academia. The first time I conversed with someone who uptalked, I thought she was asking me questions and I tried to figure out how to answer. Then it dawned on me that in fact, this was how she spoke!
