One investigator, Walter Gogel
of the University of California
at Santa Barbara, believes that,
even though subjects may have
no usable information in such
a dark-room experiment, they
nonetheless have a tendency to
localize the object at some
specific distance from
themselves, roughly between 6
and 8 feet. Although Gogel
presents evidence for the
existence of such a "specific-
distance tendency," as he calls
it, the fact remains that objects
viewed under the conditions of
the dark-room experiment are
difficult to localize with any
certainty or precision and are
subjectively indeterminate in
size.
What potential sources of
information about distance
have we eliminated in this
experiment? By making use of a
similar procedure in the
laboratory, investigators have
isolated several different cues.
Some of these cues are
inherent in our eyes
themselves and in the
structure and functioning of
the visual nervous system;
others are inherent in the
characteristics of the objects
viewed and in the manner in
which they project images to
the eye.
