This is an interesting study. I've always had trouble understanding speech in anything but a quiet environment. Even the small amount of audio information lost in a phone conversation makes it hard for me to understand what people are saying. However, I don't think I'm depressed any more than the average person (we all have down days sometimes). So, while depressed people seem to experience this kind of reduced speech comprehension, I wonder what other groups of people experience the same?
