The Perception of Egocentric
Orientation
When subjects wear inverting
optical devices, they
eventually learn to negotiate
the environment successfully.
At first, however, they
frequently misjudge the
location of objects.
How do we manage to perceive
veridically the orientations of
things, or a scene as a whole,
in relation to ourselves? This
question is often posed
because, as most people know,
even though the image of the
scene on the back of the eye is
upside down and reversed left
to right, we see the world as
upright in relation to
ourselves. This is not the
difficult problem that it may
first appear to be, however. In
fact, the more interesting and
puzzling problem is how we
would perceive the world if the
retinal image were turned
around and made upright.
