"Allowing the use of (the fingers of) both hands would cause many unforeseen effects on the brain, which would make it hard to interpret the results" so all participants had to "type using the right index finger [only]". How does one rule out the relevance of those "unforeseen effects" when claiming to compare typing in general vs handwriting in general? The paper only contains that one line about the matter, in the…

I think it gets worse > To prevent artifacts produced by head and eye movements caused by shifting gaze between the screen and the keyboard, typed words did not appear on the screen while the participant was typewriting. So no only were typists not touch typing, they couldn't see what they were typing. Too many variables are changed between the two tests. A) writers can see whole words vs no visual feedback B) writer…

This is how I feel as a left hander while writing the old fashioned way. I can’t see what I’m writing so I get sloppy really quickly, and always need paper with lines.

Not that this makes their methodology not totally bunk, of course.

There might be no 'normally' remaining any more : I've heard that in some «almost only words» fields, laptops for students (and projectors for professors) got generalized during lectures (?), while in math-heavy fields (and I assume, anything involving frequently having to do drawings / schematics), paper for students (and blackboards for professors) were still overwhelmingly used only a few years ago, and I predict…

I think things like iPads aren't uncommon, at least that's what I was using - but handwriting on an iPad is virtually identical to pen and paper, so no real difference.

But this is not handwriting vs typing. It's handwriting vs. "a weird input method none of the participants had ever used before", namely pecking at the keyboard with one finger of one hand.

But if the results were null, would anyone share and repost the article?

Earlier quoted context omitted.

We'll have to disagree on that, since IMHO even e-paper falls short of paper (while having other benefits of course)

The paper: https://www.frontiersin.org/journals/psychology/articles/10.... DOI: doi.org/10.3389/fpsyg.2023.1219945

So the study's findings only hold where typewriting means typing "the presented word using the right index finger on the keyboard," i.e. like a pigeon. It looks like this was done because while handwriting is a unihemispheral activity, typing with both hands is not. But it trashes the results from a practical perspective.

Which makes me wonder whether typing with both hands, hence using both hemispheres, actually results in more widespread connectivity in the brain.
