Interesting article. There's a type of psychotherapy called EMDR (http://en.wikipedia.org/wiki/EMDR) which claims that moving the eyes from side to side during the recall of traumatic experiences can help reprocess the trauma in a beneficial manner, but I've never known what to make of this theory. Maybe there is something to it after all.

For any westerner, moving their eyes left-right is what happens when reading, and learning and reading have been linked since, well, learning to read.

Is moving the eyes from side to side enough of a mimicry of reading to prime onesself to learn things?

Does the same hemispheric communication enhancement happen when reading?
