Is screen-reading really reading? People want to know
by Daniel Halevi Bloom
I am worried that reading on screens
might not be as good as reading on paper, this is why I am hoping
that MRI brain scans will be used in the future to research the issues
involved.
I am calling for this research because I am concerned that reading on
screens might be not be as good as reading on paper in terms of brain
chemisty, and I want to know the facts, from the standpoint of
neuroscience. And if I am wrong about my hunch that paper reading is
superior to screening, then I will adjust my thinking accordingly. I
want to see the facts, presented by experts. Anecdotal evidence no
longer cuts the cake. We need facts.
Is reading on paper surfaces, the same text, superior, inferior, or
the same, compared to reading the same text on a screen, in terms of
brain chemistry and which regions of the brain light up in regard to
processing the info, retaining it and critically thinking about it.
Nobody has done this research yet. Gary Small, a top UCLA scientist,
told me recently that it is possible to do this, but that it is costly
and expensive. He said his team is busy with other things, but that he
hopes to see the work done soon, too.
Doing MRI brain scan research on lab volunteers reading on paper
compared to others reading on screens (Kindles or Nooks or iPhones or
computer screens) will be expensive. But institutions like UCLA,
Harvard, Princeton and Tufts and other major universities in Europe,
Taiwan and Japan will be able to carry out this research over the next
few years. Scholars like Anne Mangen in Norway, Maryanne Wolf at
Tufts, Oliver Sacks at Columbia and Gary Small at UCLA are aware of
these issues and will likely be at the forefront of the research. It
might take five years, it might ten years, but the studies and
academic papers will come out.
I have no idea what the research will say. The MRI studies might show
the reading on paper is superior to reading on screens, or they might
say the opposite. Or they might say there is no real difference. But
we need to find out with neuroscience, not just anecdotal evidence.
So far, there has not been even one academic paper published about MRI
brain scan studies on this topic. However, several top people in the
field have told me that such research is imperative and that it will
happen sooner or later.
I am only zeroing in on MRIs as a target method but using PET brain
scans would also do the trick. We need research by academics and
neuroscientists worldwide on how the brain "does" reading -- both on
screens and on paper surfaces -- to learn more about these phenomena,
and both PET scans and MRI scans will be useful for the studies.
Research scientists will know better which method fits their mode of
research.
Let's say that huge differences are seen between
reading a book on paper compared to reading the same book on a screen.
Will it mean anything?
If the differences are huge, it will mean something, for sure. If the
differences are very slight, maybe it will not mean much. And if there
are no differences, then we can all relax. And if it turns out that
screening reading is superior to paper reading, then that’s good to
know too. We need to ask neuroscientists to tell us what’s going on.
However, as Dr Small at UCLA recently told a reporter for the Los
Angeles Times: "People tend to ask whether this is good or bad," Small
said. "My response is that the tech train is out of the station, and
it’s impossible to stop.”
He was referring to an earlier note that online readers often
demonstrate what he calls "continuous partial attention" as they click
from one link to the next. The risk is that we become mindless ants
following endless crumbs of digital data, Small indicated. But his
final note that the tech train is already out of the station and
cannot be stopped is telling.
It is highly likely that ereader manufacturers and the entire computer
industry will pay little attention to whatever findings come out. If
the findings back the superiority of reading off screens, they will
rejoice and help to publish the results. If the findings say that
reading on paper and reading off screens is more or less the same, in
terms of brain chemistry and reception, then they will also rejoice.
But if the findings come back that paper reading is superior to screen
reading, it won’t make a difference to the e-reader industry. As a
friend of mine in the industry told me recently:
"Just as dire warnings about cancer and radiation from excessive
cellphone use have more or less gone unheeded, the same thing will
happen with the results of the MRI tests on paper reading versus
screen reading. It’s too late to do anything about it. The reading
devices are already out there in the marketplace and in the schools. I
don’t think a few warnings will change a thing. It didn’t stop the
cellphone industry. It won’t stop the e-reader makers. It’s a billion
dollar industry, and it’s getting hotter every day."
