Has anyone come across peer-reviewed research on the effect of text page formatting on cognitive load? I'm more particularly interested on wider evidence about whether working with column width, one can compensate for the difficulty of texts that use lengthy paragraphs that render them more difficult to comprehend.
I've seen some previous related questions, like this one, but even the most researched answers there limit themselves to providing some web links.
I've also looked up some research on the topic, but whereas (1) and (2) were insightful, they didn't address specifically my question
