Once the alternative is
achievedΓÇöΓÇôor what amounts to
the same thing, when subjects
are initially told about the
alternativesΓÇöΓÇôthe situation is
entirely different
psychologically. Now the
observer knows that the figure
is reversible, and the
alternative perceptions are
represented in memory.
Therefore, merely thinking
about the alternative not being
perceived at any given moment
may suffice to lead to a
perceptual reorganization in
which it is perceived. In short,
the explanation of reversal in
the case of informed observers
may have more to do with an
intention to reverse and a
shifting memory reference
than with neural fatigue.
However, as noted above, the
fatigue theory cannot be ruled
out as a contributing factor;
some evidence supports it.
