Back in the early 1960's when I was in grade school, I was among the students who scored high enough (color code purple) on the
SRA Reading Kit to be allowed some training with a weird gizmo that I now know was a
tachistoscope. I am now a fast reader (about a book and a half a day), and do tend to notice things that flash by quickly.
However,
correlation does not imply causation, so I do not know if my tachistoscope training created my speed reading, or if I was just born a fast reader and the tachistoscope did absolutely nothing.
