Reading fluency was measured by a tachistoscope, which flashes a word
on a screen for a few milliseconds. The quicker one can recognize it,
the more skilled a reader you are. Fluency was higher in Notel in
grades 2 and 3 in Phase 1, but dropped back to similar levels with
Unitel and Multitel in Phase 2. However, there seemed to be little
effect on fluency among 8th graders, possibly because their reading
skills had been established by that age. The researchers thought that
TV hindered the acquisition of reading skills simply because it took
up so much time. Reading is a difficult skill, after all, and doesn't
become pleasurable or useful until you're good at it. If TV distracts
you from practising it in that crucial stage, you may never get good
reading habits. Once you have it, though, TV seems less harmful.
An interesting effect was hypothesized by the researchers. TV was
originally thought to be a great leveller, since both rich and poor
would be watching the same programs and would be provided with the
same news and information. Instead, the reverse may be happening.
Increased TV viewing in poorer households harms those kids' reading
abilities and habits. They thus do less reading throughout school and
so have less access to the primary (although far from the only) source
of knowledge. The gap in education is thus widened, not narrowed.
