Yes. In fact, it is not limited to third-graders. I once sat in a class of intelligent undergraduates taking first-year Chinese. These were people who could format APA citations on hand-written exams. When asked to write a paragraph in Chinese, they often started at the edge of the paper, went all the way to the other edge, leaving no margins. The issue seems to be: are you comfortable enough with a language that some portion of your brain can focus on whether what you're writing looks nice, or are you straining so thoroughly just to control the micro motor movements that these is no attention left for macro aesthetics?
