There is a growing body of evidence that suggests
that our brain processes information in at least two major systems. The image
system appears to be associated with the right hemisphere of the brain. This
hemisphere seems to be specialized to process visual and auditory imagery,
spatial representation, pure melodic thought, fantasy, and the emotional
components of consciousness. Imagery allows us to continue to process
information when we are not actively looking at or listening to new stimuli, It
reproduces the sounds or sights of the past, enriching our thoughts, dreams, or
fantasies with a sense of "actuality" or context. As a coding system, imagery
operates by what is called "parallel" processing, e. g., we imagine the face of
a friend in one instantaneous configuration. The lexical system
is largely coordinated through the left hemisphere of the brain, and its chief
functions include language and grammatical organization, abstract
conceptualization and reasoning. This verbal or linguistic system functions
sequentially; it takes time for a sentence to run its course so it can be
understood. The lexical dimension is especially efficient for
integrating diverse phenomena under one label or formula that allows extremely
rapid retrieval of stored information (memories) later. Both
imagery and lexical systems seem essential for the highest levels of thought. It
is possible, however, that the immediacy of television precludes our more active
integration of images and words. We need time to replay mentally material just
witnessed and also to link pictures and sounds to word labels that make for the
most efficient kind of storage and retrieval. So rapidly does television
material come at us that it defies the capacities of our brain to store much of
it unless we actively turn our attention from the set and engage in some kind of
mental rehearsal. Only in the instant "replay" of sports programming does the
medium itself consciously abet the human requirement for
reduplication. Contrast this with the situation of reading. You
are in control of the pace. You can reread a sentence, turn back to an earlier
page and take the time to piece together combinations of images and words. As
you read you are also likely on occasion to drift away into more extended
private images and thoughts about the material. In effect, you
are engaging in a more creative act of imagination and perhaps also in the
forming of new combinations of words and images. Reading seems, therefore,
harder work than watching television but ultimately more rewarding because it
enhances your own imaginative capacities. We're not so naive as
to believe that television can be eliminated from the household, as some
suggest. Rather, we see the necessity for encouraging producers to free
themselves from the assumption that the rapid paced, quick-cut format, whether
directed at children or adults, is a necessity.
