When
geometric
or
contoured
shapes are
generated
as
disparity regions
in
dynamic
random-dot
stereograms, the question
of
whether
the subject’s
response
is
evoked
largely
by
boundaries and
corners
of
the
disparate
region
arises.
To
examine
this
question
a disparate
square

shifted randomly within
a
focal region at one millisecond
intervals, resultmg
in
a
nebulous
stimulus
which

view.
The
technique
may
be regarded
as
an analogue
of
the
defocusing
technique
used
to resolve
similar questions
about evoked
potentials
to
patterned
stimuli.
Average visual
evoked
potentials
(VEP)
