Because the objection of
Boring and others could be met
in this way, and because
BoringΓÇÖs own theory was
implausible, it seemed proper to
reopen the investigation of the
taking-into-account theory as
an explanation of the moon
illusion. In the early 1960s,
Lloyd Kaufman and I developed
a set of experiments to test this
theory. The basic idea behind
our initial experiments was
quite simple, namely to create
artificial moons that, optically
speaking, would be far away
from the observer, just as the
real moon is. To make
immediate comparison
possible, and thus avoid the
possible inexactitude caused by
the long delay typical in
observing the moon in its
different celestial locations
under natural conditions, we
created two such artificial
moons. To make measurement
of the illusion possible, we
designed the disk of light
simulating a moon so that its
size could be varied.
