In GibsonΓÇÖs experiment,
visual and touch perception are
in direct conflict. If touch
information were the ultimate
source of how things appear
visually, touch should be
dominant. However, the results
of later experiments were
always the same as in GibsonΓÇÖs
observation. Not only did vision
dominate, but the tactual
"feel" of the object conformed
to the visual "look" of it. Vision
captured touch.
In one experiment, for
example, Jack Victor and I
created a conflict of size
between the two senses. The
subject looked through a lens
(without realizing it was a lens)
at a square of a certain size.
Using vision alone, subjects
judged the square to be about
one-half its true size (exactly
what one would predict
knowing the minification
value of the lens). Using touch
aloneΓÇöΓÇôgrasping the square
without looking at itΓÇöΓÇôsubjects
judged the size more or less
correctly, as they should have,
since there was no distortion
with respect to touch. But when
looking and grasping
simultaneously, subjects
experienced the square to be
half its size, corresponding to
how they experienced it by
vision alone. Moreover, the
square felt to them as if it were
half size. We did a similar
experiment on shape. The
result was the same: Visual
capture of touch occurred.
