Hand in Hand

ResearchBlogging.orgIn my recent endeavor to cut back on paper consumption, I've converted bank statements to digital versions, put a stop to mail catalogs, and have been doing most of my reading and writing online.

Speaking of, I've also been writing for www.Miller-McCune.com including their blog Today in Mice--check it if you like the kind of stuff you're reading here. But I diverge, the real issue that I'm blogging about today goes with reading/writing on the computer.

There's one bit of paper that I can't eliminate from my life; it's the writing that I do while I read science. At first I thought it was just a habit, scribbling notes and flow charts in the margins of scientific papers. But when I keep notes on the computer, without pen in hand, the information seems to trickle away like a lost train of thought.

A recent study published in the Journal of Cognitive Neuroscience suggests that it may be better to learn by writing (with your hand that is). In other words, learning and motor function go hand in hand.

Scientists from the Universite Paul Sabatier, the Universite de La Mediterranee and the Hopital de La Timone in France primarily interested in how we learn characters or symbols for written language, gave twelve subjects new characters to learn, either by handwriting or typing them. When tested, the individuals remembered the the funny lines and loop-d-loops and their orientation best when they were practiced by handwriting. Using motor skills to hit a key--even though the time spent on the task was equivalent--didn't cut it.

One intriguing aspect of the study is that the researchers used brain imaging to compare the neural pathways involved in both processes. Broca's area, historically associated with speech, is gaining recognition for a more broad role in language. The authors discern that the “left Broca's area activation seems to depend on the motor knowledge associated with the characters.”

This research is directly relevant to children learning to write. My preschool aged daughter, obsessed with the computer, sees me typing and wants to do her writing too. Letting her practice her letters with enlarged fuschia-font, I used to feel pretty good about the exercise. While the activity is not detrimental, I now make an extra effort to have her put in sufficient time with paper and pencil.

Taking the research to the level of comprehension may be speculative but the direct implications of this study and my anecdotal evidence is keeping paper in our lives.

Filtered Science

I ask every science writer I meet the same question.

Trace science blog articles back to the primary literature and you'll notice a strikingly high proportion source from open access articles. This goes for many news headlines too. Especially freelance science writers are disabled when it comes to accessing journal articles.

When I was a university employee, it was easy to take the library -the access- for granted. The process by which scientists and their discoveries make headlines or blog lines didn't seem a mystery when I had gloved hands. Fascinating science was obvious. The experiments leaped out of the journal. Even if the science wasn't ground breaking, the topics were gripping and the experiments, telling.

But now that my gloves are off and my password not functional, titles jump from the screen, topics may seem tantalizing -but they're just titles, topics and abstracts. Getting the article, the details of the research -or the background- is another story.

My question to the science writers I meet: Access, how do you get it? The solutions I've come across are always disappointing. The best involve relying on open access articles and retrieving the articles directly from the author. Sure there are ways; but the once deft, gloved hands are now somewhat tied.

What's more disappointing than not having fingertip access to all the cutting edge research, is the realization that the public in turn doesn't either -the science to some degree is filtered.
