This theory is a controversial 
one and may seem farfetched, 
but it has great predictive 
power. For example, the 
interposition cue can be 
interpreted along these lines: 
seeing “two rectangles” is 
simpler than seeing a rectangle 
nestled against an L-shaped 
figure because a rectangle is 
more regular than an L-shape 
and because both figures are 
then alike. In the cue of size 
perspective, the outcome is 
that the objects all become 
equal in size rather than 
different. In the case of the 
kinetic depth effect, one might 
say that a rigid object rotating 
in depth is a simpler outcome 
than an object transforming in 
length and orientation within 
a plane.
