ABSTRACT:
Like humans, pigeons exhibit multistability of perception when they are confronted with
a constant stimulus pattern like the so-called orthogonal alternative movement (OAM):
Perception switches between two interpretations of the unchanging sensory stimulus. In the
experiment we reported here, five pigeons were trained to discriminate horizontal and vertical
apparent motion stimuli and were then tested with seven (multistable) OAM stimuli that
differed in their aspect ratios. Because for humans there exists a dominance of verticality, the
OAM pattern that leads to an equal distribution of the two perceptual interpretations has to
be horizontally biased (aspect ratio 0.62). Contrary to that, the results we obtained suggest
that for pigeons a comparable dominance of verticality does not exist. The possible contribution
for an explanation of the preference of verticality by human observers of OAM patterns
of other well-known factors of the visual field anisotropy that differ for humans and pigeons
are discussed.
