It's obvious to me based on my own experiences. Of course I'm talking about a "French as a Foreign/Second Language" major, not "French" like they teach in American high schools. And I'm talking about Computer Science or Software Engineering majors, not self-taught webpage developers. The rough visual-verbal spectrum for learners is obvious for me, and when teaching, we need activities that utilize both the visual and verbal faculties. I'm surprised you haven't encountered this continuum.
