Experimental
study on right-left problems in visual balance
K. Hirata |
This
experiment, using right-handed and right-eyed subjects under three
viewing conditions-binocular, monocular right and monocular Left-examined
their placement of the fulcrum of visual balance between paired,
right-left, squares. (1) The psychological balance point, under all
three viewing conditions, tended to be placed towards the center
from the physically expected point of balance, (2) Significant differences
in overestimating the right-hand square were shown under binocular
and monocular left (non-dominant eye) viewing conditions but were
not shown under monocular right (dominant eye) viewing condition.
(3) Under the binocular viewing condition, even when the difference
in size between the right-left squares was increased, the distances
between the psychological and physically expected balance points
did not show a significant difference, however under monocular, in
comparison with under the binocular viewing condition, as the difference
in size of the right-left squares was increased the difference in
right-left visual weight tended to be overestimated, and as the difference
between the two squares was decreased the difference in visual weight
tended to be underestimated. (4) Individual differences were shown.
It was shown that binocular balance point could not be predicted
in any straightforward fashion from monocular balance points.
