As a relation of objects in the
world, interposition is simple
enough to grasp, but, as a
perceptual phenomenon, it is
difficult to explain. The central
problem can be seen by trying
the following experiment. Cut
out two cardboard objects, a
circle and a rectangle. Cut a
small notch in the circle into
which the corner of the
rectangle can fit, as shown in
the illustration at left. Then
align the two objects as shown,
with the rectangle behind the
circle. When you view the
objects with one eye from the
appropriate vantage point, it
will seem that the rectangle is
occluding the circle and you
will receive the impression
that the rectangle is nearer.
But note that the stimulus your
eye receives is ambiguous. You
could just as easily perceive the
arrangement veridically (as it
is) as perceive it as two objects
in the same plane fitted
together like a jigsaw puzzle.
The conclusion that the
interposition depth
interpretation is preferred
therefore seems warranted.
