If the border between two
regions is formed by a line, as
in an outline drawing, one
region can be figure and the
other, ground. These relations
can also be reversible, with the
border always assigned to the
figure. Of course, a contour
that is just a line in itself is
neither convex nor concave,
but this feature is still ascribed
to whatever region is perceived
as figure. The two possible
figural percepts can be so
different from one another as
shapes, despite their
dependence on an identical
contour, that we may predict
that if observers organize the
pattern one way at one time,
the pattern as a whole will not
be recognized if it is organized
the opposite way at a later time.
Rubin did this experiment with
just this result.
