Abstract
Intention is known to crucially influence perceptual reversal. How does it work in daily life? To tap this question, a pair of real eyeglasses, ambiguous in their perspective, were presented, and observers were either informed of the reversibility or not, for 60 s monocularly. The results showed that, when in the direction that the lenses were further away than the legs, more observers with intention achieved the reversal. However, when viewed in the opposite direction, most observers failed regardless of intention. Interestingly, across both viewing conditions, most observers? initial organization was the direction that the lenses were nearer, which was suspected more familiar. That is, only when the initial organization was conflict with the veridical organization, observers intention was effective for the reversal, suggesting that the role of intention might be minimal in a real world, rather the relationship between the initial and veridical organizations is more important.
