    The program of those who
share this theoretical
perspective, then, is to
discover what the higher-order
features of the stimulus are for
every kind of perception. By
essentially considering a
perception as a response and
the features of the input as a
stimulus, they attempt to
sidestep assumptions about the
mind in much the same way as
the Behaviorists do.

THE INFORMATION PROCESSING
PERSPECTIVE In the last several
decades a new approach has
arisen. Instead of thinking of
the stimulus on the retina in
terms of energy, it is thought of
as information that is then
processed by the brain. A
number of separate
developments converged to
form the basis of this approach,
such as the invention of
computers and Cybernetics,
which made use of concepts
such as bits and channels of
information. One of the
founding fathers of this
approach was the British
psychologist Donald Broadbent.
Following the experiments of
the British investigator E. Colin
Cherry, in which different
messages were transmitted to
the ears simultaneously,
Broadbent outlined a theory in
which attention was thought of
as the selection of one channel
or another by means of filters
that allowed only the stimuli
from one channel to be
transmitted deeper into the
brain. Other investigators such
as Ulric Neisser, then at
Brandeis University, sought to
analyze the stages of
information processing that led
to the development of internal
representations.
