Not so much about how language controls thoughts, but more how thoughts can be traced in language. But maybe these experiments could help with this question. Check out this Radiolab
podcast. Here's the synopsis:
In today’s podcast, a look at what scientists uncover when they treat words like data. In Agatha’s case, an English professor makes a diagnosis decades after her death. And in a study involving 678 nuns—as Dr. Kelvin Lim and Dr. Serguei Pakhomov from the University of Minnesota explain—an unexpected find in a convent archive leads to a startling twist. In both examples, words serve as a window into aging brains…a window that may someday help pinpoint very early warning signs for Alzheimer’s disease and dementia. We also hear from Sister Alberta Sheridan, a 94-year-old Nun Study participant.
