In experiments such as
Stratton performed, observers
will adapt to this abnormal
change in direction during
their movement. After a few
days, the scene no longer
appeared to Stratton to move
when he moved. It was not
simply that he grew accustomed
to such motion effects and
stopped attending to them. The
proof is that, on removing the
lenses at the end of the
experiment, the scene
appeared to move whenever
Stratton moved and in a
direction opposite to the
direction in which it appeared
to move when he first put the
lenses on. This kind of
outcome, of perceiving things
opposite to the way they
appeared when distorting
optical devices were worn
(generally referred to as a
negative aftereffect), can be
taken as strong proof that an
adaptive change has occurred.
We can therefore conclude that
StrattonΓÇÖs perceptual system
learned, while he was wearing
inverted lenses, that the
change of direction of
stationary things during his
own movement is toward the
direction of his movement, not
opposite to it, as is normally
the case.
